STA510A:44 V, 5.5 A quad power half-bridge digital audio amplifier

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 device is intended for the output stage of a stereo all-digital high-efficiency (DDX®) amplifier which employs a pulse-width modulator driver.

The STA510A is capable of delivering an output power of 50 W into 3 Ω x 4 channels with THD = 10% at VCC = 37 V in single ended configuration. It can also deliver 100 W + 100 W into 6-Ω loads with THD = 10% at VCC = 36 V in BTL configuration and 200W into 3 Ω with THD = 10% at VCC = 36 V in single paralleled BTL configuration.

The input pins have a threshold proportional to the voltage on pin VL.
