Overview
The STA510FTR, produced by STMicroelectronics, is a monolithic, quad, half-bridge stage in multipower BCD technology. This device is designed to be highly versatile and can be configured as a dual-bridge or reconfigured into a single-bridge with double current capability by adjusting the CONFIG pin. It is particularly suited for use in stereo all-digital high-efficiency (FFX) amplifiers, capable of delivering significant power outputs with low distortion.

Applications
The STA510FTR is primarily used in high-efficiency audio amplifiers, particularly in stereo all-digital FFX amplifiers. It can deliver up to 100 W + 100 W output power into 6 Ω loads with a total harmonic distortion (THD) of 10% and a supply voltage (VCC) of 36 V. In single BTL (Bridge-Tied Load) configuration, it can deliver up to 200 W into a 3 Ω load under similar conditions.
Other potential applications include mono BTL configurations and quad half-bridge configurations, making it versatile for various high-power audio systems.
