Guaranteed Matching Characteristics
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.
