LT1024

Dual, Matched

Picoampere, Microvolt Input,

Low Noise Op Amp

FEATURES

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

temperaturerange), microvoltoffsetvoltage(andlowdrift

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.

■

Guaranteed Offset Voltage: 50µV Max

■

Guaranteed Bias Current:

25°C: 120pA Max

–55°C to 125°C: 700pA Max

■

Guaranteed Drift: 1.5µV/°C Max

■

Low Noise, 0.1Hz to 10Hz: 0.5µV_P-P

■

Guaranteed Supply Current: 600µA Max

■

Guaranteed CMRR: 112dB Min

Guaranteed PSRR: 112dB Min

■

Guaranteed Voltage Gain with 5mA Load Current

Guaranteed Matching Characteristics

■

Tight matching is guaranteed on offset voltage,

noninverting bias currents and common mode and power

supply rejections.

APPLICATIO S

■

Strain Gauge Signal Conditioner

■

Dual Limit Precision Threshold Detection

The all-around excellence of the LT1024 eliminates the

necessityofthetime-consumingerroranalysisprocedure

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.
