GENERAL DESCRIPTION
The TC911 CMOS auto-zeroed operational amplifier is
the first complete monolithic chopper-stabilized amplifier.
Chopper operational amplifiers like the ICL7650/7652 and
LTC1052 require user-supplied, external offset compensa-
tion storage capacitors.
External capacitors are not re-
quired with the TC911.
Just as easy to use as the conven-
tional OP07 type amplifier, the TC911 significantly reduces
offset voltage errors. Pinout matches the OP07/741/7650
8-pin mini-DIP configuration.
Several system benefits arise by eliminating the exter-
nal chopper capacitors: lower system parts count, reduced
assembly time and cost, greater system reliability, reduced
PC board layout effort and greater board area utilization.
Space savings can be significant in multiple-amplifier de-
signs.
Electrical specifications include 15
μ
V maximum offset
voltage, 0.15
μ
V/
°
C maximum offset voltage temperature
coefficient. Offset voltage error is five times lower than the
premium OP07E bipolar device. The TC911 improves off-
set drift performance by eight times.
The TC911 operates from dual or single power sup-
plies. Supply current is typically 350
μ
A. Single 4.5V to 16V
supply operation is possible, making single 9V battery
operation possible. The TC911 is available in 2 package
types: 8-pin plastic DIP and SOIC.
