LTC6257 - Linear Technology

LTC6257 65uA Power Efficient Rail-to-Rail I/O Op Amps

The LTC®6255/LTC6256/LTC6257 are single/dual/quad operational amplifiers with low noise, low power, low supply voltage, and rail-to-rail inputs and outputs. They are unity gain stable with or without capacitive loads. They feature 6.5MHz gain-bandwidth product, 1.8V/µs slew rate while consuming only 65µA of supply current per amplifier operating on supply vo.
