RS8557, RS8558, RS8559
Zero-Drift, Rail-to-Rail I/O CMOS Operational Amplifiers
FEATURES
DESCRIPTION
• Low Offset Voltage: ±3uV (TYP)
The RS8557, RS8558, RS8559 series of CMOS
• Input Offset Drift: ±0.03μV/°C
operational amplifiers use auto-zero techniques to
• High Gain Bandwidth Product: 4.3MHz
simultaneously provide very low offset voltage (20μV
• 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
max) and near-zero drift over time and temperature.
