Overview
The STA510F is a monolithic, quad, half-bridge stage in multipower BCD technology, designed and manufactured by STMicroelectronics. This device is particularly suited for use in high-efficiency, all-digital audio amplifiers. It can be configured as a dual-bridge or reconfigured into a single-bridge with double current capability by adjusting the CONFIG pin. The STA510F is capable of delivering significant power output, such as 100 W + 100 W into 6 Ω loads with a THD of 10% and VCC of 36 V in stereo BTL configuration, and up to 200 W into a 3 Ω load in single BTL configuration under the same conditions.
