The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates. CONNECTION DIAGRAM QFN PACKAGE 32-PIN (TOP VIEW) TERMINAL FUNCTIONS PIN TYPE(1) DESCRIPTION NO. NAME 1 PLIMIT I Power limit level adjust. Connect a resistor divider from GVDD to GND to set power limit. Connect directly to GVDD for no power limit. 2 GVDD PO Internally generated gate voltage supply. Not to be used as a supply or connected to any component other than a 1uF X7R ceramic decoupling capacitor. 3 GAIN/SLV I Sets Gain and selects between Master and Slave mode depending on pin voltage divider. 4 GND G Ground 5 INNL I Negative audio input for left channel. Biased at 3V. 6 INPL I Positive audio input for left channel. Biased at 3V. 7 MUTE I Mute signal for fast disable/enable of outputs: HIGH = outputs OFF (high-Z), LOW = outputs ON. TTL logic levels with compliance to AVCC. 8 AM2 I AM Avoidance Frequency Selection 9 AM1 I AM Avoidance Frequency Selection 10 AM0 I AM Avoidance Frequency Selection 11 SYNC DIO Clock input/output for synchronizing multiple class-D devices. Direction determined by GAIN/SLV pin. Input signal not to exceed GVDD (7V) 12 AVCC P Analog Supply 13 PVCC P Power supply 14 PVCC P Power supply 15 BSPL BST Boot strap for positive left channel output, connect to 220nF X7R ceramic cap to OUTPL 16 OUTPL PO Positive left channel output 17 GND G Ground 18 OUTNL PO Negative left channel output (1) TYPE: DO = Digital Output, I = Analog Input, G = General Ground, PO = Power Output, BST = Boot Strap. 2 Submit Documentation Feedback Copyright © 2013, Texas Instruments Incorporated Product Folder Links: TPA3131D2 TPA3132D2 |
