Description
The STA515W is a monolithic quad half-bridge
stage in Multipower BCD Technology. The device
can be used as a dual bridge or reconfigured, by
connecting pin CONFIG to pins VDD, as a single
bridge with double-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 10 W x
4 channels into 4 loads with 10% THD at
VCC = 18 V in single-ended configuration.
It can also deliver 20 W + 20 W into 8 loads
with 10% THD at VCC = 18 V in BTL configuration
or, in single parallel BTL configuration, 40 W into
a 8 load with 10% THD at VCC = 26 V.
The input pins have a threshold proportional to
the voltage on pin VL.
The STA515W comes in a 36-pin PowerSSO
package with exposed pad down (EPD).

Figure 8 below shows a single-BTL configuration capable of supplying 40 W into a 4 load
at 10% THD with VCC = 19 V. This result was obtained with peak power for <1 s using the
STA308+STA515W+STA50X demo board. A PWM modulator as driver is required.
