TLC27L1

TLC27L1, TLC27L1A, TLC27L1B
CMOS LOW POWER OPERATIONAL AMPLIFIERS
Description
Pin Assignments
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.
New Product
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.
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
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.
Wide range of supply voltages over specified temperature
range:
0°C to +70°C . . . 3 V to 16 V
–40°C to +85°C . . . 4 V to 16 V

Single-Supply Operation

Common-Mode Input Voltage Range
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.

Application Information
Parameter measurement circuits
Because the TLC271 is optimized for single-supply operation, circuit configurations used for the various tests can present some difficulties
since the input signal must be offset from ground. This issue can be avoided by testing the device with split supplies and the output load tied
to the negative rail. Example circuits are shown below.

Application Notes
Offset Voltage Nulling Circuit
The TLC27L1 offers external input offset null control. Nulling of the input off set voltage may be achieved by adjusting a 100-kΩ potentiometer
connected between the offset null terminals with the wiper connected as shown in Figure 31.

Input Bias Current – Error Protection
The TLC27L1 has an extremely high input impedance. To use the inputs as a high impedance node, for example, greater than100K, or to
accurately measure bias current, it is necessary to place a guard ring around the input pins and drive the ring to a potential equivalent to the
common mode input voltage. In many cases this common mode potential may exist as a part of the feedback circuit and can be obtained from
one of the appropriate nodes. In the case for the SO8 package, pin 4 is connected to ground or Vdd-. Input pins 2 and 3 are normally well
above the voltage on pin 4, so a large potential voltage on the order of several volts is likely between pins 3 and 4. To prevent interference with
a 1 pA bias current, the board resistance will need to be in the order of gigaohms to have a minimum impact. The goal is to have the common
mode potential on the guard ring, therefore reducing the stray voltage near the input pins to millivolts in normal applications. Any solder flux
residue, excess moisture, humidity or board contamination will be detrimental to using the device in a high impedance input mode.
