RS8538, RS8539

Zero-Drift, Rail-to-Rail I/O CMOS Operational Amplifiers

Features

Description

The RS8538, RS8539 series of CMOS operational

amplifiers use auto-zero techniques to simultan-

eously provide very low offset voltage (5uV max)

and near-zero drift over time and temperature. This

family of amplifiers has ultralow noise, offset and

power.

•

Low Offset Voltage: ±1uV (TYP)

Input Offset Drift: ±0.005uV/°C

High Gain Bandwidth Product: 1.6MHz

Rail-to-Rail Input and Output

High Gain, CMRR, PSRR:130dB

High Slew Rate: 0.7V/us

Low Noise: 1.3uVp-p (0.01Hz~10Hz)

Low Power Consumption: 180uA /op amp

Overload Recovery Time:2us

Low Supply Voltage: +2.5 V to +5.5 V

No External Capacitors Required

Extended Temperature: -40°C to +125°C

This miniature, high-precision operational amplifiers

offer high input impedance and rail-to-rail input and

rail-to-rail output swing. With high gain-bandwidth

product of 1.6MHz and slew rate of 0.7V/us.

Single or dual supplies as low as +2.5V (±1.25V)

and up to +5.5V (±2.75V) may be used.

The RS8538/RS8539 are specified for the extended

industrial and automotive temperature range (-40°C

to 125°C ). The RS8538 single amplifier is available

in 5-lead SOT23, 8-lead MSOP and 8-lead SOIC

packages, The RS8539 dual amplifier is available in

8-lead SOIC and 8-lead MSOP narrow surface

mount packages.
