LT1884/LT1885

Dual/Quad Rail-to-Rail

Output, Picoamp Input

Precision Op Amps

FEATURES

DESCRIPTIO

■

Offset Voltage: 50µV Max (LT1884A)

The LT^®1884/LT1885 op amps bring high accuracy input

performance to amplifiers with rail-to-rail output swing

while providing faster response than other precision am-

plifiers. Input offset voltage is trimmed to less than 50µV

and the low drift maintains this accuracy over the operat-

ing temperature range. Input bias currents are an ultralow

400pA maximum.

■

Input Bias Current: 400pA Max (LT1884A)

■

Offset Voltage Drift: 0.8µV/°C Max

■

Rail-to-Rail Output Swing

■

Operates with Single or Split Supplies

■

Open-Loop Voltage Gain: 1 Million Min

■

1mA Maximum Supply Current Per Amplifier

■

Slew Rate: 1V/µs

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

Slew rates of 1V/µs with a supply current of less than 1mA

per amplifier give superior response and settling time

performance in a low power precision amplifier.

■

Instrumentation Amplifiers

■

Battery-Powered Systems

■

Photo Current Amplifiers

■

Precision Integrators

The dual LT1884 is available with standard pinouts in

8-pin SO and PDIP packages. The quad LT1885 is also in

the standard pinout 14-pin SO package.
