• Manufacturer Part Number: MCP654
• Description: 50 MHz, 6 mA Op Amps with mCal
• Manufacturer: MICROCHIP [Microchip Technology]

A significant amount of current can flow out of the
inputs (through the ESD diodes) when the common
mode voltage (V

The input stage of the MCP651/2/4/5/9 op amps uses
a differential PMOS input stage. It operates at low com-
mon mode input voltage (V

When operating at very low non-inverting gains, the
output voltage is limited at the top by the V
