TLC27L1, TLC27L1A, TLC27L1B
CMOS LOW POWER OPERATIONAL AMPLIFIERS
Description
The TLC27L1 operational amplifier combines a wide range of input
offset-voltage grades with low offset-voltage drift and high input
impedance. The TLC27L1 is a low-bias version of the TLC271
programmable amplifier.
Three offset-voltage grades are available, ranging from the low-cost
TLC27L1 (10mV) to the TLC27L1B (2mV) low-offset version. The
devices are offered in both commercial and industrial operating
temperature ranges.
Pin Assignments
New Product
The extremely high input impedance and low bias currents, in
conjunction with good common-mode rejection and supply voltage
rejection, make these devices a good choice for new state-of-the-art
designs as well as for upgrading existing designs.
The devices also exhibit low-voltage single-supply operation, with a
common-mode input-voltage range including the negative rail.
Features
Wide range of supply voltages over specified temperature

Applications
The TLC27L1 is the low power version of the TLC271. It offers low
power for applications requiring long battery life. For applications
that require more performance consider the TLC271.
The TLC27L1 is well suited to many consumer audio, industrial and
other low power applications. Consider carefully the bandwidth and
slew rate requirements for a specific application.

5. Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device. These are stress ratings only;
functional operation of the device at these or any other conditions beyond those indicated under recommended operating conditions is not implied.
Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
6. All voltage values, except differential voltages, are with respect to ground.
7. Differential input voltages are at IN+ with respect to IN-.
8. The output may be shorted to either supply. Temperature and/or supply voltages must be limited to ensure that the maximum dissipation rating is
not exceeded.
9. For operating at high temperatures, the TLC27L1 must be derated 8.5mW/°C to zero based on a +150°C maximum junction temperature and a
thermal resistance of +117 °C/W when the device is soldered to a printed circuit board, operating in a still air ambient.
