MCP6V28-E/SN

MCP6V28-E/SN Description

The MCP6V28-E/SN from Microchip Technology is a high-precision, zero-drift operational amplifier designed for applications requiring ultra-low offset voltage and minimal input bias current. Packaged in an 8-pin SOIC and supplied in tubes, this surface-mount IC operates over a 2.3V to 5.5V supply range, making it suitable for both low-voltage and standard 5V systems. With a 2 MHz gain bandwidth product (GBW) and 1V/µs slew rate, it balances speed and precision, while consuming only 620µA supply current, ideal for power-sensitive designs. Its 2 µV input offset voltage and 7 pA input bias current ensure exceptional accuracy in signal conditioning and sensor interfacing.
