Low noise, 4.3MHz, RRIO, zero drift single channel operational amplifier
CBM8557.pdf | 2.27M

The CBM8557, CBM8558, CBM8559 series of CMOS operational amplifiers use auto-zero techniques to simultaneously provide very low offset voltage (50μV max) and near-zero drift over time and temperature. This family of amplifiers has ultra low 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 CBM8557/CBM8558/CBM8559 are specified for the extended industrial and automotive temperature range (-40°C to 125°C). The CBM8557 single amplifier is available in 5-lead SOT23, 8-lead MSOP8 and 8-lead SOIC packages, The CBM8558 dual amplifier is available in 8-lead SOIC and 8-lead MSOP narrow surface mount packages, The CBM8559 quad amplifier is available in 14-lead SOIC and 14-lead narrow TSSOP packages.
