Description
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 loads with THD = 10% at
VCC = 51 V or, in single BTL configuration, 400 W
into a 3 load 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).
