MCP6L04T-E/ST Test Circuit
The test circuit is designed to evaluate both DC and AC characteristics of the operational amplifier. It allows engineers to independently adjust the common-mode voltage (VCM) and output voltage (VOUT’) to verify parameters such as gain, offset voltage, CMRR, PSRR, and open-loop gain.
In this setup, resistors RF and RG (both 100 kΩ) define the amplifier’s gain, while small capacitors CF (6.8 pF) provide frequency compensation to prevent oscillation. The load network, consisting of RL = 10 kΩ and CL = 60 pF, simulates typical output conditions. Meanwhile, decoupling capacitors CB1 (100 nF) and CB2 (1 µF) are connected across the supply rails to reduce power noise and enhance signal integrity.
Through this configuration, the circuit accurately measures key performance indicators such as differential-mode gain, input offset voltage, and output swing.
