Description

General part information

LTC6269 Series

The LTC6268/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.ApplicationsTrans-Impedance AmplifiersADC DriversCCD Output BufferPhotomultiplier Tube Post-AmplifierLow IBIASCircuits
