TC913A/TC913B
Package Type
General Description:
The TC913 is the world’s first complete monolithic, dual
auto-zeroed operational amplifier. The TC913 sets a
new standard for low-power, precision dual-operational
amplifiers. Chopper-stabilized or auto-zeroed amplifi-
ers offer low offset voltage errors by periodically sam-
pling offset error, and storing correction voltages on
capacitors. Previous single amplifier designs required
two user-supplied, external 0.1μF error storage correc-
tion capacitors — much too large for on-chip integra-
tion. The unique TC913 architecture requires smaller
capacitors, making on-chip integration possible.
Microvolt offset levels are achieved and external
capacitors are not required.
The TC913 system benefits are apparent when con-
trasted with a TC7650 chopper amplifier circuit imple-
mentation. A single TC913 replaces two TC7650’s and
four capacitors. Five components and assembly steps
are eliminated.
The TC913 pinout matches many popular dual-opera-
tional amplifiers: OP-04, TLC322, LM358, and ICL7621
are typical examples. In many applications, operating
from dual 5V power supplies or single supplies, the
TC913 offers superior electrical performance, and can
be a functional drop-in replacement; printed circuit
board rework is not necessary. The TC913’s low offset
voltage
potentiometers often needed with bipolar and low
accuracy CMOS operational amplifiers.
The TC913 takes full advantage of Microchip’s
proprietary CMOS technology. Unity gain bandwidth is
1.5 MHz and slew rate is 2.5V/μsec.
