MCP6034-E/ST

MCP6034-E/ST Description

The MCP6034-E/ST from Microchip Technology is a general-purpose operational amplifier (op-amp) featuring four independent channels in a compact 14-TSSOP surface-mount package. Designed for low-power applications, it operates over a wide supply voltage range of 1.8V to 5.5V, making it suitable for battery-powered and portable electronics. With an ultra-low input bias current of 1 pA and a modest gain bandwidth product of 10 kHz, this op-amp is optimized for precision signal conditioning in low-frequency circuits. Its low supply current of 900nA per channel (3.6µA total for all four) ensures minimal power consumption, while the 150µV input offset voltage enhances DC accuracy.
