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
P-P
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.
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.
