DESCRIPTION
LOW NOISE: 2.8µV
PP
The OPA379 family of micropower, low-voltage
D
D
D
microPower: 5.5µA (max)
operational amplifiers is designed for battery-powered
applications. These amplifiers operate on a supply voltage
as low as 1.8V. High-performance, single-supply
operation with rail-to-rail capability makes the OPA379
family useful for a wide range of applications.
LOW OFFSET VOLTAGE: 1.5mV (max)
DC PRECISION:
− CMRR: 100dB
− PSRR: 2µV/V
In addition to microSize packages, the OPA379 family of
op amps features impressive bandwidth (90kHz), low bias
current (25pA), and low noise (80nV/√Hz) relative to the
very low quiescent current (5.5µA max).

WIDE SUPPLY VOLTAGE RANGE: 1.8V to 5.5V
microSize PACKAGES
The OPA379 (single) is available in SC70-5, SOT23-5,
and SO-8 packages. The OPA2379 (dual) comes in
SOT23-8 and SO-8 packages. The OPA4379 (quad) is
offered in a TSSOP-14 package. All versions are specified
from −40°C to +125°C.

gain (A ) typical values are 100dB or better.
OL
When designing for ultra-low power, choose system
components carefully. To minimize current consumption,
select large-value resistors. Any resistors will react with
stray capacitance in the circuit and the input capacitance
of the operational amplifier. These parasitic RC
combinations can affect the stability of the overall system.
A feedback capacitor may be required to assure stability
and limit overshoot or gain peaking.
Figure 1. Input Current Protection for Voltages
Exceeding the Supply Voltage
NOISE
Although micropower amplifiers frequently have high
wideband noise, the OPA379 series offer excellent noise
performance. Resistors should be chosen carefully
Good layout practice mandates the use of a 0.1µF bypass
capacitor placed closely across the supply pins.
because the OPA379 has only 2.8µV of 0.1Hz to 10Hz
PP
noise, and 80nV/√Hz of wideband noise; otherwise, they
can become the dominant source of noise.
OPERATING VOLTAGE
OPA379 series op amps are fully specified and tested from
+1.8V to +5.5V. Parameters that vary significantly with
supply voltage are shown in the Typical Characteristics
curves.
CAPACITIVE LOAD AND STABILITY
Follower configurations with load capacitance in excess of
30pF can produce extra overshoot (see typical
characteristic, Small-Signal Overshoot vs Capacitive
Load) and ringing in the output signal. Increasing the gain
enhances the ability of the amplifier to drive greater
capacitive loads. In unity-gain configurations, capacitive
load drive can be improved by inserting a small (10Ω to
INPUT COMMON-MODE VOLTAGE RANGE
The input common-mode voltage range of the OPA379
family typically extends 100mV beyond each supply rail.
This rail-to-rail input is achieved using a complementary
input stage. CMRR is specified from the negative rail to 1V
below the positive rail. Between (V+) − 1V and (V+) + 0.1V,
the amplifier operates with higher offset voltage because
of the transition region of the input stage. See the typical
characteristic, Offset Voltage vs Common-Mode Voltage.
20Ω) resistor, R , in series with the output, as shown in
S
Figure 2. This resistor significantly reduces ringing while
maintaining DC performance for purely capacitive loads.
However, if there is a resistive load in parallel with the
capacitive load, a voltage divider is created, introducing a
Direct Current (DC) error at the output and slightly
reducing the output swing. The error introduced is
proportional to the ratio R /R , and is generally negligible.
S
L
PROTECTING INPUTS FROM
OVER-VOLTAGE
Normally, input currents are 5pA. However, large inputs
(greater than 500mV beyond the supply rails) can cause
excessive current to flow in or out of the input pins.
Therefore, as well as keeping the input voltage below the
maximum rating, it is also important to limit the input
current to less than 10mA. This limiting is easily
accomplished with an input voltage resistor, as shown in

In unity-gain inverter configuration, phase margin can be
reduced by the reaction between the capacitance at the op
amp input and the gain setting resistors, thus degrading
capacitive load drive. Best performance is achieved by
using smaller valued resistors. However, when large
valued resistors cannot be avoided, a small (4pF to 6pF)
capacitor, CFB, can be inserted in the feedback, as shown
in Figure 3. This configuration significantly reduces

LOW-SIDE CURRENT MONITOR
WINDOW COMPARATOR
The micropower OPA379 is well suited for current
monitoring circuits in applications such as a voltage
regulator with fold-back current limiting, or a high-current
power supply with crowbar protection. Figure 5 shows the
OPA379 monitoring the current in a power-supply return
path using a 0.1Ω shunt resistor. The NPN transistor, Q1
(2N2222 or equivalent) is used to generate equal voltages
at the inverting and noninverting inputs. Therefore, the
