AUTO-ZEROED OPERATIONAL AMPLIFIERS

GENERAL DESCRIPTION

FEATURES

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 15µV maximum offset

voltage, 0.15µV/°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 350µA. 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.
