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 amplifiers
offer low offset voltage errors by periodically sampling
offset error, and storing correction voltages on capacitors.
Previous single amplifier designs required two user-sup-
plied, external 0.1
μ
F error storage correction capacitors —
much too large for on-chip integration. 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 implemen-
tation. A single TC913 replaces two TC7650's and four
capacitors. Five components and assembly steps are elimi-
nated.
The TC913 pinout matches many popular dual-
operational 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
error eliminates offset voltage trim potentiometers often
needed with bipolar and low-accuracy CMOS operational
amplifiers.
The TC913 takes full advantage of TelCom's propri-
etary CMOS technology. Unity gain bandwidth is 1.5 MHz
and slew rate is 2.5 V/
μ
sec.
