Description
The CD8538, CD8539 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 +2.7V (±1.35V) and up to +5.5V (±2.5V) may be used. The CD8538/CD8539 are specified for the extended industrial and automotive temperature range (-40°C to 125°C).
The CD8538 single amplifier is available in 5-lead SOT23, 8-lead MSOP and 8-lead SOIC packages, The CD8539 dual amplifier is available in 8-lead SOIC and 8-lead MSOP narrow surface mount packages.
