The CD8561, CD8562, CD8564, (dual version &shutdown) series of CMOS operational amplifiers use auto-zero techniques to simultaneously provide very low offset voltage (20μV 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 11MHz and slew rate of 8.5V/μs. Single or dual supplies as low as +2.9V (±1.45V) and up to +5.5V (±2.75V) may be used.
The CD8561/CD8562/CD8564 (dual version with shutdown) are specified for the extended industrial and automotive temperature range (-40°C to 125°C). The CD8561 single amplifier is available in 5-lead SOT23, 8-lead MSOP8 and 8-lead SOIC packages, The CD8562 dual amplifier is available in 8-lead SOIC and 8-lead MSOP narrow surface mount packages, The CD8564 quad is available in 14-lead SOIC and 14-lead narrow TSSOP packages.
