1 / 10 page Ordering number : ENN6657 72502RM (OT) No. 6657-1/10 Overview The LA4802T is a headphone stereo power amplifier for portable CD and MD players. It features a high signal-to- noise ratio, a high ripple rejection ratio, low distortion, and low current drain. Functions • Headphone stereo power amplifier • Power switch • Muting switch • Beep tone function control input pin (The beep tone function can be used regardless of whether the mute function is on or off.) Features • High signal-to-noise ratio (100 dB typical at 7.5 µV) • High ripple rejection ratio (70 dB typical) • Low current drain (950 µA typical) • On-chip bass compensation circuit (Compensates for bass frequency attenuation due to the output capacitors and achieves flat frequency characteristics.) • Ultraminiature package (MSOP-20) Package Dimensions unit: mm 3262-MSOP20 5.2 0.5 (0.35) 0.125 1 10 20 11 0.2 SANYO: MSOP20 [LA4802T] LA4802T SANYO Electric Co.,Ltd.
