BETAMCP6022Dual rail-to-rail CMOS operational amplifier
Two fast analog channels from a single low-voltage supply.
MCP6022 integrates two CMOS operational amplifiers with rail-to-rail inputs and outputs. Both channels share a 2.5–5.5 V supply, but each has independent signal inputs, feedback and output. The typical gain-bandwidth product is 10 MHz. The example uses a 5 V supply and a common 0.50 V DC input. Channel A has a gain of three and channel B is a voltage follower, producing ideal outputs of 1.50 V and 0.50 V. Local 100 nF bypass and nearby 1 µF bulk storage help keep the supply quiet. This page follows the industrial MCP6022-I/P and MCP6022-I/SN parts, specified from −40 to +85°C. It is the dual amplifier: the reference-voltage output and chip-select feature of certain single-amplifier family members do not exist on MCP6022.
