www.DataSheet4U.com MITSUMI I2C BUS - Controlled 11-Input 3-Output Audio Switch MM1631 I2C BUS - Controlled 11-Input 3-Output Audio Switch Monolithic IC MM1631 Outline This is an I2C BUS controlled audio switch developed for use in TVs, PDP and projection TVs. It can switch among 11 audio signal (R, L) lines and 3 output lines. Input switching block design is simple when this IC and MM1630 (video switch) are used as a pair. Features 1. The desired input can be selected for each of the 3 independent output lines. 2. Wide dynamic range (3vrms). 3. Serial control possible through I2C BUS. 4. Forced mute enabled by external pin. 5. Built-in Power Save function. 6. I2C BUS line maintains high impedance when power is off. 7. No output waveform folding with 7.1Vrms input Package SSOP-36A Pin Assignment 36 35 34 33 32 31 30 29 28 27 26 25 24 23 22 21 20 19 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 SSOP-36A (TOP VIEW) 1 2 3 4 5 6 7 8 9 L3 R3 L4 R4 L5 R5 L6 R6 L7 10 11 12 13 14 15 16 17 18 R7 L8 R8 L9 R9 L10 R10 L11 R11 19 20 21 22 23 24 25 26 27 BIAS MUTE ADR SDA SCL GND ROUT3 LOUT3 ROUT2 28 29 30 31 32 33 34 35 36 LOUT2 ROUT1 LOUT1 VCC VCC L1 R1 L2 R2 www.DataSheet4U.com MITSUMI I2C BUS - Controlled 11-Input 3-Output Audio Switch MM1631 Block Diagram L1 33 L2 35 0dB L3 L4 L5 L6 L7 1 3 5 7 9 0dB 29 ROUT1 30 LOUT1 L8 11 L9 13 L10 15 L11 17 R1 34 R2 36 R3 R4 R5 R6 2 4 6 8 0dB 26 LOUT3 0dB 27 ROUT2 0dB 28 LOUT2 R7 10 R8 12 0dB R9 14 R10 16 R11 18 25 ROUT3 BIAS 19 BIAS L...
