AN7535NSA

ICs for Audio Common Use AN7535NSA Headphone amplifier IC for portable equipment 7.8±0.3 Unit : mm 13 s Overview The AN7535NSA is an audio signal processing IC in which line amplifiers and beep circuit are built in the headphone amplifiers for use in portable equipment. Its headphone output block is using the center amplifier method which eliminates the need for coupling capacitor so that the circuit is most suitable for rationalization of audio circuit. 24 6.1±0.3 8.1±0.3 1 12 0.525±0.1 1.2±0.2 (0.5) (0.325) 0.65 0.22−0.05 Seating plane +0.1 Output coupling capacitor is not required (Center amplifier method) Built-in line amplifiers Built-in headphone amplifier gain change-over circuit (8 dB/12 dB) Built-in mute circuit Built-in beep circuit Built-in circuit against a shock noise generated when power supply is momentary cut off. 0.525±0.1 s Features 0.15 Seating plane SSOP024-P-0300B s Applications Potable CD and MD players, etc. s Block Diagram 24 23 22 21 20 1 19 1 18 17 16 15 14 Mute VREF Beep 8/12 dB Ripple Filter 10 11 12 1 2 3 4 5 6 7 8 9 8/12 dB 13 0.1±0.1 1 AN7535NSA s Pin Descriptions Pin No. 1 2 3 4 5 6 7 8 9 10 11 12 VCC1 Ripple filter Supply voltage Headphone amplifier ch.1 output pin N.C.
