Description

The CBM8561, CBM8562, CBM8564, (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 CBM8561/CBM8562/CBM8564 (dual version with shutdown) are specified for the

extended industrial and automotive temperature range (-40°C to 125°C). The CBM8561 single

amplifier is available in 5-lead SOT23, 8-lead MSOP8 and 8-lead SOIC packages, The CBM8562

dual amplifier is available in 8-lead SOIC and 8-lead MSOP narrow surface mount packages, The

The CBM8564 quad is available in 14-lead SOIC and 14-lead narrow TSSOP packages.
