MAX9622: Precision, high-bandwidth op amp improves system efficiency in power modules

Maxim introduced the MAX9622, a precision operational amplifier with high gain bandwidth. This op amp employs a unique autotrimming technique to precisely calibrate the input-offset voltage (Vos) on power-up. This approach enables the device to achieve a Vos of only 100microvolts (max) to allow the use of a small sense resistor, thus improving system efficiency by reducing sense resistor power consumption. The MAX9622 is well suited for active filter design and low-side current sensing in power modules and automotive power supplies.
