描述 Description

The RS8538, RS8539 series of CMOS operational amplifiers use auto-zero techniques to simultaneously 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 offset 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 +2.7V(±1.35V) and up to +5.5V (±2.75V) may be used.

The RS8538/RS8539 are specified for the extended industrial and automotive temperature range (-40°C to 125°C). The RS8538 single amplifier is available in 8-lead MSOP8 and 8-lead SOIC packages, The RS8539 dual amplifier is available in 8-lead SOIC and 8-lead TSSOP narrow surface mount packages.
