LT1024

Dual, Matched

Picoampere, Microvolt Input,

Low Noise Op Amp

DESCRIPTIO

The LT

1024 dual, matched internally compensated

universal precision operational amplifier can be used in

practically all precision applications requiring multiple op

amps. The LT1024 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. Extremely high

common mode and power supply rejection ratios,

practically immeasurable warm-up drift, and the ability to

deliver 5mA load current with a voltage gain of a million,

round out the LT1024’s superb precision specifications.

Tight matching is guaranteed on offset voltage,

noninverting bias currents and common mode and power

supply rejections.

The all-around excellence of the LT1024 eliminates the

necessity of the time-consuming error analysis procedure

of precision system design in many dual applications; the

LT1024 can be stocked as the universal dual op amp in the

14-pin DIP configuration.

For a single op amp with similar specifications, see the

LT1012 data sheet; for a single supply dual precision op

amp in the 8-pin configuration, see the LT1013 data sheet.
