65-volt, 7.5-amp, quad power half bridge
  • active Active

STA516B is a monolithic quad half-bridge stage in multipower BCD technology. The device can be used as dual bridge or reconfigured, by connecting pin CONFIG to pins VDD, as a single bridge with double-current capability or as a half bridge (binary mode) with half 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 200 W + 200 W into 6 Ω loads with THD = 10% at VCC= 51 V or, in single BTL configuration, 400 W into a 3 Ωload with THD = 10% at VCC= 52 V.

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

The STA516B is aimed at audio amplifiers in hi-fi applications, such as home theatre systems, active speakers and docking stations.

It comes in a 36 pin PowerSO package with exposed pad up (EPU).
