Overview
The OP462GS from Analog Devices Inc. is a quad rail-to-rail operational amplifier designed for high-speed and low-voltage applications. This amplifier is part of the OPx62 family, which includes the OP162 (single) and OP262 (dual) versions. The OP462GS is fabricated using Analog Devices’ high-speed complementary bipolar process, known as XFCB, which enhances its performance by reducing parasitic capacitances. This makes the OP462GS an excellent choice for applications requiring fast and accurate signal processing.
