These devices offer 3MHz unity gain bandwidth. They also feature low input bias currents of 1pA and 10 mA output drive. The combination of low supply currents, low offsets, very low input bias currents, and wide supply range make these amplifiers useful in a wide variety of low power applications. REV.
