Product Summary

The STA510A is a monolithic quad half bridge stage in Multipower BCD Technology. The device can be used as dual bridge or reconfigured, by connecting pin CONFIG to VDD, as a single bridge with double current capability, or as half bridges (Binary mode) with half current capability. The STA510A is intended for the output stage of a stereo all-digital high-efficiency (DDX) amplifier which employs a pulse-width modulator driver.
