    The CBM8538, CBM8539 series of CMOS operational amplifiers use auto-zero techniques to simultan-eously 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 offer high input impedance and rail-to-rail input and rail-to-rail output swing. With high gain-bandwidth product of 1.6MHz and slew rate of 0.7V/μs.  

     Single or dual supplies as low as +2.5V(±1.25V) and up to +5.5V (±2.75V) may be used.

   The CBM8538/CBM8539 are specified for the extended industrial and automotive temperature range (-40°C to 125°C). The CBM8538 single amplifier is available in 5-lead SOT23, 8-lead MSOP and 8-lead SOIC packages, The CBM8539 dual amplifier is available in 8-lead SOIC and 8-lead MSOP narrow surface mount packages.
