DESCRIPTION
The LTC®6268-10/LTC6269-10 is a single/dual 4GHz 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, and
high-impedance sensor amplifiers. It is a decompensated
op amp that is gain-of-10 stable.
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 LTC6268-10 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 LTC6269-10 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.
