Microchip MCP6001 CMOS Op-Amp, 1MHz, SOT-23, Single

The Microchip MCP6001T-I/OT is a single, low-power operational amplifier engineered for a wide range of general-purpose applications. Manufactured using Microchip’s state-of-the-art CMOS process, this op-amp delivers a balance of low power consumption and high performance, making it ideal for space-constrained and battery-powered designs.

This device features a gain bandwidth product of 1MHz (typical) and rail-to-rail input and output, allowing maximum dynamic range and ease of use in single-supply systems. With a supply voltage range from 1.8V to 6.0V and a low quiescent current of 100µA per amplifier (typical at VDD = 5.5V), the MCP6001 is optimised for energy-efficient operations.

The op-amp provides a typical phase margin of 90°, ensuring stability even when driving larger capacitive loads. Its high precision is evidenced by a maximum input offset voltage of 4.5mV, along with excellent power supply rejection ratio (86dB typical) and common-mode rejection ratio (76dB typical).

Packaged in a compact 5-lead SOT-23 surface-mount package, the device operates over an extended temperature range from -40°C to +85°C, making it suitable for demanding industrial and automotive environments. The MCP6001 is a flexible, cost-effective solution for a variety of analogue signal conditioning tasks.

Typical Applications

Its low-voltage and low-power characteristics make it well-suited for automotive electronics, portable equipment, photodiode amplifiers, analogue filters, notebooks, PDAs, and other battery-powered systems. The rail-to-rail output swing and high phase margin allow for reliable performance in portable and sensor interface circuits.
