Description

STA508 is a monolithic quad half bridge stage in Multipower BCD technology. The

device can be used as dual bridge or reconfigured, by connecting CONFIG pin to

Vdd pin, as single bridge with double current capability, and as half bridge (Binary

mode) with half current capability.

The device is particularly designed to make the output stage of a stereo all-digital

high efficiency (DDX™) amplifier capable to deliver 80 + 80 W @ THD = 10 % at VCC

= 35 V output power on 8 Ω load.

In single BTL configuration is also capable to deliver a peak of 160 W @ THD = 10

% at VCC = 35 V on 4 Ω load. The input pins have threshold proportional to VL pin

voltage.
