NY9A802B General Description:
The NY9A802B is mono audio power amplifier CMOS IC. They are designed by LSI high technology with a lowpower and low-cost process. Less peripheral components are required in application. NY9A802B is a BridgeTied Load (BTL) power amplifier. It is capable of delivering 2.5W of average power to a 4Ω load or 3.0W of average power to a 3Ω load with less than 10% distortion (THD+N) from a 5V power supply.
NY9A802B Features:
(1). Wide operating voltage range: VDD = 2.0V ~ 5.5V.
(2). Bridge-Tied Load (BTL).
(3). High output power: POUT is 2.5W for VDD = 5V, Load =4Ω, f = 1kHz and THD+N = 10%.
(4). Low standby (shutdown) current. (Typ.=0.1uA)
(5). Support PWM differential signal input.
(6). No output coupling capacitors, snubber networks or bootstrap capacitors required.
(7). BTL output can directly drive capacitive loads such like piezo-buzzer.
(8). Built-in auto Ramp-up/ Ramp-down circuit to minimize the turn-on and turn-off pop noise. The time of
Ramp-up can be adjusted by Cb bypass capacitor.
(9). Built-in Thermal Shutdown (TSD).
(10). High 5KV Human Body Mode (HBM) ESD protection.
(11). SOP-8 package.
