PGA870IRHDR Overview

There is a 28-VFQFN Exposed Pad case package that contains the instrumentation amplifiers. The instrumentation amplifier in this picture is of the Programmable Gain-type. Upon delivery, op amp ic is packaged in a Tape & Reel (TR) case. We are approaching the 28h termination of the year. In total, there are 28 pins on this op amp ic. This linear amplifier should be powered by an 5V battery. There are two types of Operational Amplifier op amps in this case, and this device falls into one of them. 28 pins are located on the operational amplifiers. This electrical part should be mounted using type Surface Mount. In terms of operating temperatures, this buffer amplifier works very well at a temperature of around -40°C~85°C . The buffer amplifier is capable of operating from a supply current of 143mA . It is recommended to keep the voltage gain at 20dB at all times. The total number of elements in this buffer amplifier is 1. The operating supply voltage of the buffer op amp is rated at 5V. This linear amplifier pack is based on the TR axis. In order for the op amp resistance to remain within the 173MOhm range, the op amp should be tested.
