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.
