RS8557, RS8558, RS8559

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

FEATURES

DESCRIPTION

The RS8557, RS8558, RS8559 series of CMOS

operational amplifiers use auto-zero techniques to

simultaneously provide very low offset voltage (20μV

max) and near-zero drift over time and temperature.

This family of amplifiers has ultralow noise, offset and

power.

•

Low Offset Voltage: ±3uV (TYP)

Input Offset Drift: ±0.03μV/°C

High Gain Bandwidth Product: 4.3MHz

Rail-to-Rail Input and Output

High Gain, CMRR, PSRR: 120dB

High Slew Rate: 2.5V/μs

Low Noise: 0.93uVp-p (0.01Hz~ 10Hz)

Low Power Consumption: 650μA/op amp

Overload Recovery Time: 1us

Low Supply Voltage: +2.7V to +5.5V

No External Capacitors Required

Extended Temperature: -40°C to +125°C

This miniature, high-precision operational amplifiers

offset high input impedance and rail-to-rail input and

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

product of 4.3MHz and slew rate of 2.5V/μs.

Single or dual supplies as low as +2.7V (±1.35V) and

up to +5.5V (±2.75V) may be used.

APPLICATIONS

The RS8557/RS8558/RS8559 are specified for the

extended industrial and automotive temperature

range (-40°C to 125°C ). The RS8557 single amplifier

is available in 5-lead SOT23, 8-lead MSOP8 and 8-

lead SOIC packages, The RS8558 dual amplifier is

available in 8-lead SOIC and 8-lead MSOP narrow

surface mount packages, the RS8559 quad amplifier

is available in 14-lead SOIC and 14-lead narrow

TSSOP packages.
