The MCP6422T-E/MS from Microchip Technology is a Dual-Channel CMOS Operational Amplifier that is ideal for portable medical instruments, safety monitoring, battery-powered systems, supply current sensing, analog active filters, and remote sensing applications. It requires a supply voltage of 1.8 - 5.5 V, an input offset voltage from -1 mV to +1 mV, and an input bias current of up to 50 pA. This op-amp provides an output current of ±22 mA. It delivers a large signal voltage gain of 115 dB and has a common-mode rejection ratio (CMRR) of 90 dB. This amplifier offers enhanced electromagnetic interference (EMI) protection to minimize any EMI-related effects from external sources. It has been designed to prevent phase reversal when the input pin voltage exceeds the supply voltage. This op-amp is supported by electrostatic discharge (ESD) protection to prevent sudden voltage spikes or over-voltage conditions. It is available in a surface-mount package that measures 3 x 3 mm.
