Description
The LTC6269, LTC6268 is a single/dual 500MHz FET-input operational amplifier with extremely low input bias current and low input capacitance. It also features low inputreferred current noise and voltage noise making it an ideal choice for high speed transimpedance amplifiers, CCD output buffers, and high-impedance sensor amplifiers. Its low distortion makes the LTC6268 / LTC6269 an ideal amplifier for driving SAR ADCs. It operates on 3.1V to 5.25V supply and consumes 16.5mA per amplifier. A shutdown feature can be used to lower power consumption when the amplifier is not in use.
