DESCRIPTION
The LTC®6268/LTC6269 is a single/dual 500MHz FET-input
operational amplifier with extremely low input bias current
and low input capacitance. It also features low input-
referred 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.
The LTC6268 single op amp is available in 8-lead SOIC and
6-lead SOT-23 packages. The SOIC package includes two
unconnected pins which can be used to create an input pin
guard ring to protect against board leakage currents. The
LTC6269 dual op amp is available in 8-lead MSOP with
exposed pad and 3mm × 3mm 10-lead DFN packages.
They are fully specified over the –40°C to 85°C and the
–40°C to 125°C temperature ranges.
