MCP601T-E/OT: Single-Supply, Low-Power CMOS Op-Amp from Microchip

In the realm of analog signal conditioning, operational amplifiers (op-amps) are fundamental building blocks. The MCP601T-E/OT from Microchip Technology stands out as a highly versatile component designed for modern, power-sensitive applications. This single-general-purpose CMOS op-amp is engineered to deliver reliable performance where power consumption and space are critical constraints.

A primary advantage of the MCP601T-E/OT is its single-supply operation, which simplifies system design by eliminating the need for a negative voltage rail. It functions seamlessly with a supply voltage range from 2.7V to 6.0V, making it an ideal choice for battery-powered devices and embedded systems powered by a single Li-Ion cell or two/three alkaline batteries. This feature is complemented by its exceptionally low quiescent current of just 100 µA (typical), which directly extends battery life in portable equipment such as sensors, handheld meters, and remote monitors.

Despite its low power draw, the device does not compromise on performance. It offers a gain bandwidth product of 2.8 MHz and a slew rate of 2.3 V/µs, providing sufficient speed for a wide array of DC and AC signal processing tasks, including filtering, amplification, and buffering. The CMOS input stage ensures very high input impedance, minimizing the loading effect on sensors or preceding circuit stages. Furthermore, the op-amp features rail-to-rail input and output operation, maximizing the dynamic range and allowing signals to swing close to both supply rails—a crucial capability in low-voltage single-supply environments.

Housed in a space-saving SOT-23-5 package, the MCP601T-E/OT is tailored for compact PCB layouts. Its extended industrial temperature range (-40°C to +125°C) guarantees robust performance in harsh environmental conditions. The combination of low power, single-supply flexibility, and small form factor makes this amplifier a go-to solution for designers aiming to enhance efficiency without sacrificing functionality.

ICGOODFIND: The MCP601T-E/OT is a quintessential low-power op-amp that masterfully balances performance with efficiency. Its single-supply, rail-to-rail operation and tiny package make it an exceptional choice for space-constrained, battery-dependent applications across industrial, automotive, and consumer markets.
