The RS8541, RS8542 series of CMOS operational amplifiers use auto-calibration techniques to simultaneously provide very low offset voltage (7μV TYP) and near-zero drift over time and temperature. This family of amplifiers has ultralow noise, offset and power. This miniature, high-precision operational amplifiers offset high input impedance and rail-to-rail input and rail-to-rail output swing. With gain-bandwidth product of 350KHz and slew rate of 0.16V/μs. Single or dual supplies as low as +2V (±1V) and up to +5.5V (±2.75V) may be used. The RS854X are specified for the extended industrial and automotive temperature range (-40°C to 125°C). The RS8541 single amplifier is available in 5-lead SOT23 package, The RS8542 dual amplifier is available in 8-lead SOP package.
