FEATURES  
DESCRIPTIO  
The LT®1012 is an internally compensated universal  
precision operational amplifier which can be used in  
practically all precision applications. The LT1012  
combines picoampere bias currents (which are  
maintained over the full –55°C to 125°C temperature  
range), microvolt offset voltage (and low drift with time  
and temperature), low voltage and current noise, and  
low power dissipation. The LT1012 achieves precision  
operation on two Ni-Cad batteries with 1mW of power  
dissipation. Extremely high common mode and  
power supply rejection ratios, practically unmeasurable  
warm-up drift, and the ability to deliver 5mA load current  
with a voltage gain of one million round out the LT1012’s  
superb precision specifications.  
OP-07 Type Performance:  
at 1/8th of OP-07’s Supply Current  
at 1/20th of OP-07’s Bias and Offset Currents  
Guaranteed Offset Voltage: 25µV Max  
Guaranteed Bias Current: 100pA Max  
Guaranteed Drift: 0.6µV/°C Max  
Low Noise, 0.1Hz to 10Hz: 0.5µVP-P  
Guaranteed Low Supply Current: 500µA Max  
Guaranteed CMRR: 114dB Min  
Guaranteed PSRR: 114dB Min  
Guaranteed Operation at ±1.2V Supplies

Replaces OP-07 While Saving Power  
Precision Instrumentation  
The all around excellence of the LT1012 eliminates the  
necessity of the time consuming error analysis procedure  
of precision system design in many applications; the  
LT1012 can be stocked as the universal internally  
compensated precision op amp.
