The Microchip MCP6141/2/3/4 family of operational amplifiers are designed for low-power, portable applications. These op amps operate with a single supply voltage as low as 1.4V and draw less than 1 µA of quiescent current per amplifier. They support rail-to-rail input and output operation, making them suitable for battery-powered devices. With a gain bandwidth product of 100 kHz and stability for gains of 10 V/V or higher, the MCP6141 is a versatile solution for various applications including toll booth tags, wearable products, and temperature measurement systems.
