Overview
The STA515W13TR is a monolithic quad half-bridge stage in Multipower BCD Technology, designed by STMicroelectronics. This device is particularly suited as the output stage of a stereo all-digital high-efficiency amplifier. It can be configured as a dual bridge or reconfigured as a single bridge with double-current capability by connecting the CONFIG pin to the VDD pins. The STA515W13TR is capable of delivering significant power, such as 10 W x 4 channels into 4 Ω loads with 10% THD at VCC = 18 V in single-ended configuration, and up to 40 W into an 8 Ω load in single parallel BTL configuration at VCC = 26 V.
