The TLC2652 and TLC2652A are high-precision
chopper-stabilized operational amplifiers using
FK PACKAGE
Texas Instruments Advanced LinCMOS pro-

cess. This process, in conjunction with unique
chopper-stabilization circuitry, produces opera-
tional amplifiers whose performance matches or
exceeds that of similar devices available today.

noise voltage is significantly reduced. This high
9 10 11 12 13
precision, coupled with the extremely high input
impedance of the CMOS input stage, makes the
TLC2652 and TLC2652A an ideal choice for
low-level signal processing applications such as
strain gauges, thermocouples, and other
transducer amplifiers. For applications that
NC − No internal connection
require extremely low noise and higher usable
bandwidth, use the TLC2654 or TLC2654A
device, which has a chopping frequency of
10 kHz.
The TLC2652 and TLC2652A input common-mode range includes the negative rail, thereby providing superior
performance in either single-supply or split-supply applications, even at power supply voltage levels as low as
±
1.9 V.
Two external capacitors are required for operation of the device; however, the on-chip chopper-control circuitry
is transparent to the user. On devices in the 14-pin and 20-pin packages, the control circuitry is made accessible
to allow the user the option of controlling the clock frequency with an external frequency source. In addition, the
clock threshold level of the TLC2652 and TLC2652A requires no level shifting when used in the single-supply
configuration with a normal CMOS or TTL clock input.

description (continued)
Innovative circuit techniques are used on the TLC2652 and TLC2652A to allow exceptionally fast overload
recovery time. If desired, an output clamp pin is available to reduce the recovery time even further.
The device inputs and output are designed to withstand
±
100-mA surge currents without sustaining latch-up.
Additionally the TLC2652 and TLC2652A incorporate internal ESD-protection circuits that prevent functional
failures at voltages up to 2000 V as tested under MIL-STD-883C, Method 3015.2; however, care should be
exercised in handling these devices, as exposure to ESD may result in degradation of the device parametric
performance.
The C-suffix devices are characterized for operation from 0°C to 70°C. The I-suffix devices are characterized
for operation from − 40°C to 85°C. The Q-suffix devices are characterized for operation from − 40°C to125°C.
The M-suffix devices are characterized for operation over the full military temperature range of −55°C to125°C.

† Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
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.
NOTES: 1. All voltage values, except differential voltages, are with respect to the midpoint between VDD + and VDD − .
2. Differential voltages are at IN+ with respect to IN −.
3. 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.
