LT1024 Dual, Matched Picoampere, Microvolt Input, Low Noise Op Amp

The LT™1024 dual, matched internally compensated universal precision operational amplifier can be used inpractically 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 LT1024µs 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 then 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 datasheet
