Anpec Electronics APA2036A

The APA2036/APA2036A is a stereo audio power amplifier in a TQFN4x4-16 or TQFN3x3-16 (APA2036A) package. When the APA2036/APA2036A is in the BTL mode with 5V supply voltage, it is capable of delivering 2.4W/2.0W/1.3W of continuous output power per channel into 3Ω/4Ω/8Ω load (Speaker) with less than 1% THD+N respectively. When the APA2036/APA2036A operates in the single-ended mode, it is capable of delivering 160mW/85mW of continuous output power per channel into 16Ω /32Ω load (Headphone).

FEATURES

GENERAL DESCRIPTION

To simplify the audio system design in notebook computer applications, the APA2036/APA2036A combines a stereo bridge-tied mode for speaker drive and a stereo single-end mode for headphone drive into a single chip, where both modes are easily switched by the SE/BTL input control pin signal. The APA2036/APA2036A also serves low-voltage applications well. The APA2036/APA2036A, with 3.3V supply voltage, provides 900mW (at 1% THD+N) per channel into 4Ω load. Both of the depop circuitry and the thermal shutdown protection circuitry are integrated in the APA2036/APA2036A. The depop function reduces pops and clicks noise during power on/off and enable/shutdown processes. The thermal protection protects the chip from being destroyed by over-temperature failure. For power sensitive applications, the APA2036/APA2036A also features a shutdown function which reduces the supply current only 0.5µA (typical).
