LT1881/LT1882

Dual and Quad

Rail-to-Rail Output,

Picoamp Input Precision Op Amps

DESCRIPTIO

FEATURES

The LT^®1881 and LT1882 op amps bring high accuracy

■

Offset Voltage: 50μV Maximum (LT1881A)

Input Bias Current: 200pA Maximum (LT1881A)

Offset Voltage Drift: 0.8μV/°C Maximum

Rail-to-Rail Output Swing

amplifiers, at the cost of a slight loss in speed. Input

offset voltage is trimmed to less than 50μV and the low

drift maintains this accuracy over the operating tempera-

ture range. Input bias currents are an ultralow 200pA

maximum.

Supply Range: 2.7V to 36V

Operates with Single or Split Supplies

Open-Loop Voltage Gain: 1 Million Minimum

1mA Maximum Supply Current Per Amplifier

Stable at A_V= 1, C_L= 1000pF

Standard Pinouts

The amplifiers work on any total power supply voltage

between 2.7V and 36V (fully specified from 5V to 15V).

Output voltage swings to within 40mV of the negative

supply and 220mV of the positive supply make these

amplifiers good choices for low voltage single supply

operation.

APPLICATIO S

■

Thermocouple Amplifiers

Bridge Transducer Conditioners

Instrumentation Amplifiers

Battery-Powered Systems

■

Capacitive loads up to 1000pF can be driven directly in

unity-gain follower applications.

■

Photo Current Amplifiers

The dual LT1881 and LT1881A are available with standard

pinouts in S8 and PDIP packages. The quad LT1882 is in

a 14-pin SO package. For a higher speed device with

similar DC specifications, see the LT1884/LT1885.
