MAX9737 Overview
The device operates from 8V to 28V and provides a high 80dB PSRR, eliminating the need for a regulated power supply. Filterless modulation allows the MAX9737 to pass CE EMI limits with 1m cables using only a low-cost ferrite bead and small-value capacitor on each output. prehensive click-and-pop suppression circuitry reduces noise on power-up/down or into and out of shutdown or mute.
