Overview
The AD745JR-16 is a high-speed, ultralow noise, BiFET operational amplifier produced by Analog Devices Inc. This amplifier is designed for applications that demand low noise and high DC precision. It is particularly useful in high-speed applications where low-level signals need to be amplified with high gain and wide bandwidth. The AD745JR-16 does not exhibit output phase reversal and offers excellent DC performance with low input bias current and offset voltage. It is available in a 16-lead SOIC package and is rated over the commercial temperature range of 0°C to 70°C.
