Description
The AD9256H is a high performance stereo digital
amplifier power stage. It can deliver 10W x 2CH output
power into 8Ω loudspeaker for stereo or 20W x 1ch
output power into 4Ω loudspeaker for mono in BTL
configuration within <1% THD+N at 15V supply.
A patented, built-in anti-pop function can reduce the
speaker’s pop noise without requiring complex
anti-pop sequence in PWM input.
The AD9256H’s chip is integrated with
over-temperature, over-current, and under-voltage
protection circuits. These additions safeguard the
AD9256H against fault conditions that could damage
the chip and system catastrophically.
