The MCP6141/2/3/4 is a low quiescent current, stable operational amplifier that can operate from a single supply voltage as low as 1.4V. This device features a gain bandwidth product of 100kHz and is stable for gains of 10V/V or higher.
The MCP6141/2/3/4 family are low‑quiescent (600 nA) non‑unity‑gain operational amplifiers that operate from a single supply as low as 1.4 V and support rail‑to‑rail input and output swings. They are offered in single (MCP6141), single with chip‑select (MCP6143), dual (MCP6142) and quad (MCP6144) configurations and are stable for gains of 10 V/V or higher.
The datasheet provides detailed electrical characteristics, including a 100 kHz gain‑bandwidth product, typical input offset voltage of ±3 mV, and a wide supply range of 1.4 V to 5.5 V. Package options include PDIP, SOIC, MSOP and TSSOP, and the document lists typical applications such as toll‑booth tags, wearable products, temperature measurement, and battery‑powered designs.
