STA515W:40 V, 3 A quad power half-bridge digital audio amplifier

The STA515W is a monolithic quad half-bridge stage in Multipower BCD Technology. The device can be used as a dual bridge or reconfigured, by connecting pin CONFIG to pins VDD, as a single bridge with double-current capability.

The device is designed, particularly, to be the output stage of a stereo all-digital high-efficiency amplifier. It is capable of delivering 10 W x 4 channels into 4 Ω loads with 10% THD at VCC = 18 V in single-ended configuration.

It can also deliver 20 W + 20 W into 8 Ω loads with 10% THD at VCC = 18 V in BTL configuration or, in single parallel BTL configuration, 40 W into a 8 Ω load with 10% THD at VCC = 26 V.

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

The STA515W comes in a 36-pin PowerSSO package with exposed pad down (EPD).
