AS15-F PDF Datasheet – Voltage Buffer, TQFP48 (EC5575-F)

A voltage buffer, also known as a voltage follower or unity-gain buffer, is an electronic circuit or amplifier with a primary function: to replicate the input voltage at its output without amplifying or attenuating it. In essence, it provides a high input impedance and a low output impedance while maintaining the same voltage level as the input.
