The RS8551-Q1, RS8552-Q1 series of CMOS operational amplifiers use auto-zero techniques to simultaneously provide very low offset voltage (100μV max) 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 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. The RS8551-Q1/RS8552-Q1 are specified for the extended industrial and automotive temperature range (-40°C to 125°C). The RS8551-Q1 single amplifier is available in 5-lead SOT23, The RS8552 Q1 dual amplifier is available in 8-lead SOP and 8-lead MSOP narrow surface mount packages.
