产品概述 返回TOP
The CXAR4190/CXAR4190A is a stereo audio power amplifier in a TQFN4x4-16 or TQFN3x3-16 (CXAR4190A) package. To simplify the audio system design in notebook computer applications, the CXAR4190/CXAR4190A 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. When the CXAR4190/CXAR4190A 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 3W/4W/8W load (Speaker) with less than 1% THD+N respectively. When the CXAR4190/CXAR4190A operates in the single-ended mode, it is capable of delivering 160mW/85mW of continuous output power per channel into 16W/32W load (Headphone). The CXAR4190/CXAR4190A also serves low-voltage applications well.The CXAR4190/CXAR4190A, with 3.3V supply voltage, provides 900mW (at 1% THD+N) per channel into 4W load. Both of the depop circuitry and the thermal shutdown protection circuitry are integrated in the CXAR4190/CXAR4190A. 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 CXAR4190/CXAR4190A also features a shutdown function which reduces the supply current only 0.5mA (typical).
