SGM8555/SGM8556

Single-Supply, Single Rail-to-Rail I/O

Precision Operational Amplifiers

GENERAL DESCRIPTION

FEATURES

The single SGM8555 and dual SGM8556 are precision

operational amplifiers which can operate from 2.5V to

5.5V single supply. These devices provide rail-to-rail

input and output operation.

● Low Offset Voltage: 90μV (MAX)

● Ultra-Low Input Bias Current: 30pA

● Low Noise Density: 21nV/ Hz at 1kHz

√

● Low Voltage Noise: 0.6μV_P-Pat 0.1Hz to 10Hz

● Gain-Bandwidth Product: 3.5MHz

● Slew Rate: 3V/μs

The SGM8555/6 offer a low offset voltage less than

90μV and an ultra-low bias current of 30pA. The

combination of characteristics makes the SGM8555/6

good choices for temperature measurements, pressure

and position sensors, strain gauge amplifiers and medical

instrumentation, or any other 2.5V to 5.5V applications

requiring precision and long-term stability.

● Voltage Gain: 133dB (TYP) at 5V

● High PSRR: 96dB (TYP)

● High CMRR: 98dB (TYP)

● Overload Recovery Time: 40μs (at V_S= 5V)

● Rail-to-Rail Input and Output

● Supply Voltage Range: 2.5V to 5.5V

● Low Supply Current: 950μA/Amplifier (TYP)

● No External Capacitors Required

● -40℃ to +125℃ Operating Temperature Range

● Small Packaging:

The SGM8555 is available in Green SOT-23-5, SOIC-8

and MSOP-8 packages. The SGM8556 is available in

Green SOIC-8 and MSOP-8 packages. They are

specified over the extended industrial temperature

range (-40℃ to+125℃).
