STA510A-4*50W数字音频功放
The STA510A is a monolithic, quad, half-bridge
stage in multipower BCD technology. The device
can be used as dual-bridge or reconfigured, by
connecting the CONFIG pin to the VDD pin, as
single-bridge with double current capability, or 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, which employs a pulse-width
modulator driver. The STA510A is capable of
delivering an output power of 50 W into 3 Ω loads
with THD = 10% and VCC = 36 V. In single BTL
configuration the device can deliver 200 W into a
3 Ω load with THD = 10% and VCC = 36 V.
The input pins have a threshold proportional to VL pin voltage.
