The TLC2652 and TLC2652A are high-precision  
chopper-stabilized operational amplifiers using  
Texas Instruments Advanced LinCMOSpro-  
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.  
FK PACKAGE  
(TOP VIEW)  
Chopper-stabilization techniques make possible  
extremely high dc precision by continuously  
nulling input offset voltage even during variations  
in temperature, time, common-mode voltage, and  
power supply voltage. In addition, low-frequency  
noise voltage is significantly reduced. This high  
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  
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.  
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of  
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
