description
The TLC2652 and TLC2652A are high-precision
chopper-stabilized operational amplifiers using
Texas
Instruments
Advanced
process. This process in conjunction with unique
chopper-stabilization circuitry produces opera
tional amplifiers whose performance matches or
exceeds that of similar devices available today.
LinCMOS
Chopper-stabilization techniques make possible
extremely high dc precision by continuously
nulling input offset voltage even during variation 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.
