Overview
The STA516B13TR, produced by STMicroelectronics, is a monolithic quad half-bridge stage in multipower BCD technology. This device is designed to serve as the output stage of high-efficiency audio amplifiers, particularly in hi-fi applications such as home theatre systems, active speakers, and docking stations. It can be configured as a dual bridge, a single bridge with double-current capability, or as a half bridge in binary mode. The STA516B is capable of delivering significant audio power, such as 200 W + 200 W into 6 Ω loads with THD = 10% at VCC = 51 V, or 400 W into a 3 Ω load in single BTL configuration with THD = 10% at VCC = 52 V.
