T he OP193 family of single-supply operational amplifiers fea-
tures a combination of high precision, low supply current and
the ability to operate at low voltages. For high performance in
single supply systems the input and output ranges include
ground, and the outputs swing from the negative rail to within
600 mV of the positive supply. For low voltage operation the
OP193 family can operate down to 1.7 volts or ±0.85 volts.

T he combination of high accuracy and low power operation
make the OP193 family useful for battery powered equipment.
Its low current drain and low voltage operation allow it to con-
tinue performing long after other amplifiers have ceased func-
tioning either because of battery drain or headroom.

CAUTIO N
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection.
Although the OP193/OP293/OP493 feature proprietary ESD protection circuitry, permanent
damage may occur on devices subjected to high energy electrostatic discharges. T herefore,
proper ESD precautions are recommended to avoid performance degradation or loss of
functionality.

T he OP193 family of operational amplifiers are single-supply,
micropower, precision amplifiers whose input and output ranges
both include ground. Input offset voltage (VOS) is only 75 µV
maximum, while the output will deliver ±5 mA to a load. Sup-
ply current is only 17 µA.

A simplified schematic of the input stage is shown in Figure 23.
Input transistors Q1 and Q2 are PNP devices, which permit the
inputs to operate down to ground potential. T he input transis-
tors have resistors in series with the base terminals to protect the
junctions from over voltage conditions. T he second stage is an
NPN cascode which is buffered by an emitter follower before
driving the final PNP gain stage.

T he output stage, shown in Figure 24, is a noninverting NPN
“totem-pole” configuration. Current is sourced to the load by
emitter follower Q1, while Q2 provides current sink capability.
When Q2 saturates, the output is pulled to within 5 mV of
ground without an external pull-down resistor. T he totem-pole
output stage will supply a minimum of 5 mA to an external
load, even when operating from a single 3.0 V power supply.
Figure 24. OP193/OP293/OP493 Equivalent Output Circuit
Q5 tracks the collector current of Q1. When Q1 is on, Q5 keeps
Q4 off, and current source I1 keeps Q2 turned off. When Q1 is
driven to cutoff (i.e., the output must move toward V–), Q5
allows Q4 to turn on. Q4’s collector current then provides the
base drive for Q3 and Q2, and the output low voltage swing is
set by Q2’s VCE,SAT which is about 5 mV.
By operating as an emitter follower, Q1 offers a high impedance
load to the final PNP collector of the input stage. Base drive to
Q2 is derived by monitoring Q1’s collector current. T ransistor

D r iving Capacitive Loads
High performance portable equipment and instruments fre-
quently use lithium cells because of their long shelf life, light
weight, and high energy density relative to older primary cells.
Most lithium cells have a nominal output voltage of 3 V and are
noted for a flat discharge characteristic. T he low supply voltage
requirement of the OP193, combined with the flat discharge
characteristic of the lithium cell, indicates that the OP193 can
be operated over the entire useful life of the cell. Figure 25
shows the typical discharge characteristic of a 1 AH lithium cell
powering the OP193, OP293, and OP493, with each amplifier,
in turn, driving 2.1 Volts into a 100 kΩ load.
OP193 family amplifiers are unconditionally stable with capaci-
tive loads less than 200 pF. However, the small signal, unity-
gain overshoot will improve if a resistive load is added. For
example, transient overshoot is 20% when driving a 1000 pF/
10 kΩ load. When driving large capacitive loads in unity-gain
configurations, an in-the-loop compensation technique is rec-
ommended as illustrated in Figure 28.
Input O ver voltage P r otection
As previously mentioned, the OP193 family of op amps use a
PNP input stage with protection resistors in series with the
inverting and noninverting inputs. T he high breakdown of the
PNP transistors, coupled with the protection resistors, provides
a large amount of input protection from over voltage conditions.
T he inputs can therefore be taken 20 V beyond either supply
without damaging the amplifier.

O utput P hase Rever sal—O P 193
The OP193’s input PNP collector-base junction can be forward-
biased if the inputs are brought more than one diode drop
(0.7 V) below ground. When this happens to the noninverting
input, Q4 of the cascode stage turns on and the output goes
high. If the positive input signal can go below ground, phase
reversal can be prevented by clamping the input to the negative
supply (i.e., GND) with a diode. T he reverse leakage of the
diode will, of course, add to the input bias current of the ampli-
fier. If input bias current is not critical, a 1N914 will add less
than 10 nA of leakage. However, its leakage current will double
for every 10°C increase in ambient temperature. For critical
applications, the collector-base junction of a 2N3906 transistor
will only add about 10 pA of additional bias current. T o limit
the current through the diode under fault conditions, a 1 kΩ
resistor is recommended in series with the input. (T he OP193’s
internal current limiting resistors will not protect the external
diode).

Input O ffset Voltage Nulling
T he OP193 provides two offset nulling terminals that can be
used to adjust the OP193’s internal VOS. In general, operational
amplifier terminals should never be used to adjust system offset
voltages. T he offset null circuit of Figure 26 provides about
±7 mV of offset adjustment range. A 100 kΩ resistor placed in
series with the wiper arm of the offset null potentiometer, as
shown in Figure 27, reduces the offset adjustment range to
400 µV and is recommended for applications requiring high null
resolution. Offset nulling does not adversely affect T CVOS per-
formance, providing that the trimming potentiometer tempera-
ture coefficient does not exceed ±100 ppm/°C.
O utput P hase Rever sal—O P 293 and O P 493
T he OP293 and OP493 include lateral PNP transistors Q7 and
Q8 to protect against phase reversal. If an input is brought more
than one diode drop (≈0.7 V) below ground, Q7 and Q8 com-
bine to level shift the entire cascode stage, including the bias to
Q3 and Q4, simultaneously. In this case Q4 will not saturate
and the output remains low.
T he OP293 and OP493 do not exhibit output phase reversal for
inputs up to –5 V below V– at +25°C. T he phase reversal limit
at +125°C is about –3 V. If the inputs can be driven below these
levels, an external clamp diode, as discussed in the previous sec-
tion, should be added.

sands of hours before requiring battery replacement, thus

Some single supply circuits work best when inputs are biased

cases a false ground can be created by using a voltage divider

T his circuit will generate a false-ground reference at 1/2 of the
supply voltage, while drawing only about 27 µA from a 5 V sup-
ply. T he circuit includes compensation to allow for a 1 µF by-
pass capacitor at the false-ground output. T he benefit of a large
capacitor is that not only does the false ground present a very
low dc resistance to the load, but its ac impedance is low as well.
T he OP193 can both sink and source more than 5 mA, which
improves recovery time from transients in the load current.
Figure 29. A Battery Powered Voltage Reference
A Single-Supply Cur r ent Monitor
Current monitoring essentially consists of amplifying the voltage
drop across a resistor placed in series with the current to be
measured. T he difficulty is that only small voltage drops can be
tolerated, and with low precision op amps this greatly limits the
overall resolution. T he single-supply current monitor of Figure
30 has a resolution of 10 µA and is capable of monitoring 30
mA of current. T his range can be adjusted by changing the cur-
rent sense resistor R1. When measuring total system current, it
may be necessary to include the supply current of the current
monitor, which bypasses the current sense resistor, in the final
result. T his current can be measured and calibrated (together
with the residual offset) by adjustment of the offset trim potenti-
ometer, R2. T his produces a deliberate temperature dependent
offset. However, the supply current of the OP193 is also propor-
tional to temperature, and the two effects tend to track. Current
in R4 and R5, which also bypasses R1, can be adjusted via a
gain trim.

Design of the reference is based on the Brokaw bandgap core
technique. Scaling of resistors R1 and R2 produces unequal cur-
rents in Q1 and Q2. T he resulting ∆VBE across R3 creates a tem-
perature-proportional voltage (PT AT ) which, in turn, produces
a larger temperature-proportional voltage across R4 and R5, V1.
T he temperature coefficient of V1 cancels (first order) the

tempco is at a minimum. Bandgap references can have start-up
problems. With no current in R1 and R2, the OP193 is beyond
its positive input range limit and has an undefined output state.
Shorting Pin 5 (an offset adjust pin) to ground forces the output
high under these circumstances and insures reliable startup
without significantly degrading the OP193’s offset drift.

Designing a true single-supply instrumentation amplifier with
zero-input and zero-output operation requires special care. T he
traditional configuration, shown in Figure 31, depends upon
amplifier A1’s output being at 0 V when the applied common-
mode input voltage is at 0 V. Any error at the output is multi-
plied by the gain of A2. In addition, current flows through
resistor R3 as A2’s output voltage increases. A1’s output must
remain at 0 V while sinking the current through R3, or a gain
error will result. With a maximum output voltage of 4 V, the
current through R3 is only 2 µA, but this will still produce an
appreciable error.

One solution to this problem is to use a pull-down resistor. For
example, if R3 = 20 kΩ, then the pull-down resistor must be
less than 400 Ω. However, the pull-down resistor appears as a
fixed load when a common-mode voltage is applied. With a 4 V
common-mode voltage, the additional load current will be 10 mA,
which is unacceptable in a low power application.

T he change in output current with temperature is the derivative
of the transfer function:
Figure 32 shows a better solution. A1’s sink current is provided
by a pair of N-channel FET transistors, configured as a current
mirror. With the values shown, sink current of Q2 is about
340 µA. T hus, with a common-mode voltage of 4 V, the addi-
tional load current is limited to 340 µA versus 10 mA with a
400 Ω resistor.

From the formulas, it can be seen that if the span trim is ad-
justed before the zero trim, the two trims are not interactive,
which greatly simplifies the calibration procedure.

Calibration of the transmitter is simple. First, the slope of the
output current versus temperature is calibrated by adjusting the
span trim, R7. A couple of iterations may be required to be sure
the slope is correct.

An OP293 in combination with an inexpensive quad CMOS
analog switch forms the precision VCO of Figure 34. T his cir-
cuit provides triangle and square wave outputs and draws only
50 µA from a single 5 V supply. A1 acts as an integrator; S1
switches the charging current symmetrically to yield positive and
negative ramps. T he integrator is bounded by A2 which acts as
a Schmitt trigger with a precise hysteresis of 1.67 volts, set by
resistors R5, R6, and R7, and associated CMOS switches. T he
resulting output of A1 is a triangle wave with upper and lower
levels of 3.33 and 1.67 volts. T he output of A2 is a square wave
with almost rail-to-rail swing. With the components shown, fre-
quency of operation is given by the equation:

T he circuit of Figure 35 uses the DAC8408 CMOS quad 8-bit
DAC and the OP493 to form a single-supply quad voltage out-
put DAC with a supply drain of only 140 µA. T he DAC8408 is
used in the voltage switching mode and each DAC has an out-
put resistance (≈10 kΩ) independent of the digital input code.
T he output amplifiers act as buffers to avoid loading the DACs.
T he 100 kΩ resistors ensure that the OP493 outputs will swing
to within 1/2 LSB of ground, i.e.:
fOUT = VCONTROL (Volts) × 10 Hz/V
but this can easily be changed by varying C1. T he circuit oper-
ates well up to 500 Hz.

T he combination of the quad OP493 and the DAC8408 quad
8-bit CMOS DAC creates a quad programmable gain amplifier
with a quiescent supply drain of only 140 µA (Figure 36). T he
digital code present at the DAC, which is easily set by a micro-
processor, determines the ratio between the fixed DAC feedback
resistor and the resistance that the DAC feedback ladder pre-
sents to the op amp feedback loop. T he gain of each amplifier is:

If the digital code present at the DAC consists of all zeros, the
feedback loop will be open causing the op amp to saturate. T he
10 MΩ resistors placed in parallel with the DAC feedback loop
eliminates this problem with a very small reduction in gain accu-
racy. T he 2.5 V reference biases the amplifiers to the center of
the linear region providing maximum output swing.
