Description
The AD9256 is a high efficiency stereo digital
amplifier power stage delivering 85% efficiency.
Devices need two power supplies for the AD9256
operation up to 15V supply for PVDD and 3.3V for
VDD. The AD9256 can deliver 10W/CH output
power into 8 Ω loudspeaker (in BTL operation)
within 1% THD+N at supply 15V.
A built-in anti-pop function can reduce the
speaker’s pop without requiring complex anti-pop
sequence in PWM input, when AD9256 is applied in
AD modulation.
The AD9256 has included protection circuits that
integrated on chip. Protections ensure the AD9256
against the fault conditions that could damage the
AD9256. These safeguards of the AD9256 include
over-temperature, over-current, and under-voltage
protection circuits.
