description
BIAS SELECT
The TLC251C, TLC251AC, and TLC251BC are
low-cost, low-power programmable operational
amplifiers designed to operate with single or dual
supplies. Unlike traditional metal-gate CMOS
operational amplifiers, these devices utilize Texas

process,
OFFSET N1
OFFSET N2
This series of parts is available in selected grades of input offset voltage and can be nulled with one external
potentiometer. Because the input common-mode range extends to the negative rail and the power consumption
is extremely low, this family is ideally suited for battery-powered or energy-conserving applications. A
bias-select pin can be used to program one of three ac performance and power-dissipation levels to suit the
application. The series features operation down to a 1.4-V supply and is stable at unity gain.
These devices have internal electrostatic-discharge (ESD) protection circuits that prevent catastrophic failures
at voltages up to 2000 V as tested under MIL-STD-883C, Method 3015.1. However, care should be exercised
in handling these devices as exposure to ESD may result in a degradation of the device parametric
performance.
Because of the extremely high input impedance and low input bias and offset currents, applications for the
TLC251C series include many areas that have previously been limited to BIFET and NFET product types. Any
circuit using high-impedance elements and requiring small offset errors is a good candidate for cost-effective
use of these devices. Many features associated with bipolar technology are available with LinCMOS
operational amplifiers without the power penalties of traditional bipolar devices. Remote and inaccessible
equipment applications are possible using the low-voltage and low-power capabilities of the TLC251C series.
Inaddition, bydrivingthebias-selectinputwithalogicsignalfromamicroprocessor, theseoperationalamplifiers
can have software-controlled performance and power consumption. The TLC251C series is well suited to solve
the difficult problems associated with single battery and solar cell-powered applications.
The TLC251C series is characterized for operation from 0°C to 70°C.

APPLICATION INFORMATION
latch-up avoidance
Junction-isolated CMOS circuits have an inherent parasitic PNPN structure that can function as an SCR. Under
certain conditions, this SCR may be triggered into a low-impedance state, resulting in excessive supply current.
To avoid such conditions, no voltage greater than 0.3 V beyond the supply rails should be applied to any pin.
In general, the operational amplifier supplies should be applied simultaneously with, or before, application of
any input signals.

APPLICATION INFORMATION
using BIAS SELECT
The TLC251 has a terminal called BIAS SELECT that allows the selection of one of three I
150, and 1000 µA typical). This allows the user to trade-off power and ac performance. As shown in the typical
conditions (10,
DD
supply current (I ) versus supply voltage (V ) curves (Figure 4), the I varies only slightly from 4 V to 16

V. Below 4 V, the I
varies more significantly. Note that the I
values in the medium- and low-bias modes at
DD
V
= 1.4 V are typically 2 µA, and in the high mode are typically 12 µA. The following table shows the
recommended BIAS SELECT connections at V

output stage considerations
The amplifier’s output stage consists of a source-follower-connected pullup transistor and an open-drain
pulldown transistor. The high-level output voltage (V ) is virtually independent of the I
selection and

increases with higher values of V and reduced output loading. The low-level output voltage (V ) decreases

with reduced output current and higher input common-mode voltage. With no load, V is essentially equal to

DD–
input offset nulling
The TLC251C series offers external offset null control. Nulling may be achieved by adjusting a 25-kΩ
potentiometer connected between the offset null terminals with the wiper connected to the device V /GND
DD–
pin as shown in Figure 2. The amount of nulling range varies with the bias selection. At an I
setting of
DD
1000 µA (high bias), the nulling range allows the maximum offset specified to be trimmed to zero. In low or
medium bias or when the amplifier is used below 4 V, total nulling may not be possible for all units.
supply configurations
Even though the TLC251C series is characterized for single-supply operation, it can be used effectively in a
split-supply configuration when the input common-mode voltage (V
supply voltage limits are not exceeded.

circuit layout precautions
The user is cautioned that whenever extremely high circuit impedances are used, care must be exercised in
layout, construction, board cleanliness, and supply filtering to avoid hum and noise pickup, as well as excessive
dc leakages.
