The RS8521, RS8522, RS8524 series of CMOS operational amplifiers use auto-zero techniques to simultaneously provide very low offset voltage (5μV 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 350KHz and slew rate of 0.17V/μs. Single or dual supplies as low as +2.3V (±1.15V) and up to +5.5V (±2.75V) may be used. The RS8521/ RS8522/ RS8524 are specified for the extended industrial and automotive temperature range (-40°C to 125°C). The RS8521 single amplifier is available in 5-lead SOT23, and 8-lead SOP packages, The RS8522 dual amplifier is available in 8 lead SOP and 8-lead TSSOP narrow surface mount packages. The RS8524 quad is available in 14-lead SOP and 14-lead narrow TSSOP packages.
