TC911B  
Monolithic Auto-Zeroed Operational Amplifers  
GENERAL DESCRIPTION  
FEATURES  
The TC911 CMOS auto-zeroed operational amplifier  
is the first complete monolithic chopper-stabilized ampli-  
fier. Chopper operational amplifiers like the ICL7650/7652  
and LTC1052 require user-supplied, external offset com-  
pensation storage capacitors. External capacitors are  
not required with the TC911. Just as easy to use as the  
conventional 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.  
■ First Monolithic Chopper-Stabilized Amplifier  
With On-Chip Nulling Capacitors  
■ Offset Voltage .................................................... 5µV  
■ Offset Voltage Drift .................................. 0.05µV/°C  
■ Low Supply Current ...................................... 350µA  
■ High Common-Mode Rejection .................... 116dB  
■ Single Supply Operation .......................4.5V to 16V  
■ High Slew Rate......................................... 2.5V/µsec  
■ Wide Bandwidth............................................1.5MHz  
■ High Open-Loop Voltage Gain  
(RL = 10kΩ) ..................................................... 120dB  
■ Low Input Voltage Noise  
(0.1Hz to 1Hz) ............................................ 0.65µVP-P  
■ Pin Compatible With ICL7650  
■ Lower System Parts Count  
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.
