Dual CMOS op-amp for low-power, wide-temperature analog conditioning
The Microchip MCP6062T-E/MNY is a dual CMOS operational amplifier with rail-to-rail output, designed for applications that demand low quiescent current and a wide supply range. The amplifier type is CMOS, which gives it a 1 pA typical input bias current—useful when buffering high-impedance sources like pH probes or photodiodes without loading the signal. The 8-TDFN (2x3) package with exposed pad aids thermal dissipation in compact layouts, and the surface-mount footprint suits automated assembly lines.
At 60 µA per channel, the MCP6062T-E/MNY sits in the micropower class. For a dual-channel device, the total quiescent draw is 120 µA typical. The 1 pA input bias current is typical for CMOS inputs; it means the designer can use high-value feedback resistors (megaohm range) without significant offset from bias current, which simplifies the gain-setting network in precision DC applications. The 150 µV typical input offset voltage is moderate for a CMOS amplifier. Designs that require sub-millivolt accuracy—like weigh scales or current-sense amplifiers—may need a trim or a chopper-stabilized part. For general-purpose signal conditioning, this offset is acceptable and keeps the BOM cost below precision-grade alternatives.
Package and mounting: 8-TDFN with exposed pad
The MCP6062T-E/MNY is supplied in an 8-WFDFN exposed-pad package, also designated as 8-TDFN (2x3). The 2 mm × 3 mm footprint saves board area compared to SOIC-8, and the exposed pad provides a low-thermal-resistance path to the PCB.
