The CSM1153, CSM1253(dual version) and CSM1453 (quad version) series of CMOS operational amplifiers use auto-zero techniques to simultaneously provide very low offset voltage (1.5μV, 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 high gain-bandwidth product of 350kHz and slew rate of 0.2V/μs. Single or dual supplies as low as +1.8V(±0.9V) and up to +5.5V (±2.75V) may be used.

The CSM1153, CSM1253(dual version) and CSM1453 (quad version) are specified for the extended industrial and automotive temperature range (-40°C to 125°C). The CSM1153 single amplifier is available in SOT-23-5, MSOP-8 and SOIC-8 packages. The CSM1253 dual amplifier is available in DFN-2×2-8, SOIC-8 and TSSOP-8 narrow surface mount packages. The CSM1453 quad amplifier is available in SOIC-14 and TSSOP-14 packages.
