The MCP651-E/SN is a high-performance operational amplifier from Microchip Technology, designed for applications requiring high bandwidth and low offset voltage. It features a gain-bandwidth product of 50 MHz and a slew rate of 30 V/¬µs, making it suitable for fast signal processing tasks. The device operates on a supply voltage range of +2.5V to +5.5V and is optimized for single-supply operation with rail-to-rail output capability. The MCP651-E/SN exhibits a low input offset voltage of ¬±200 ¬µV (maximum) and a typical input bias current of 6 pA, ensuring high accuracy in signal amplification. It is also characterized by low noise performance, with a noise density of 7.5 nV/,àöHz at 1 MHz. The amplifier supports a low-power mode, drawing only 5 ¬µA per channel, which is beneficial for battery-operated devices. This op-amp is specified for an extended temperature range of -40¬8C to +125¬8C, making it suitable for industrial and automotive applications. Typical applications include driving A/D converters, current sensing, and audio signal processing. The MCP651-E/SN is available in compact package options such as SOT23-5 and DFN, facilitating integration into space-constrained designs.
