4 / 43 page  TPA3116D2, TPA3118D2, TPA3130D2 SLOS708E – APRIL 2012 – REVISED SEPTEMBER 2015 www.ti.com Pin Functions PIN TYPE(1) DESCRIPTION NO. NAME 1 MODSEL I Mode selection logic input (LOW = BD mode, HIGH = 1 SPW mode). TTL logic levels with compliance to AVCC. 2 SDZ I Shutdown logic input for audio amp (LOW = outputs Hi-Z, HIGH = outputs enabled). TTL logic levels with compliance to AVCC. 3 FAULTZ DO General fault reporting including Over-temp, DC Detect. Open drain. FAULTZ = High, normal operation FAULTZ = Low, fault condition 4 RINP I Positive audio input for right channel. Biased at 3 V. 5 RINN I Negative audio input for right channel. Biased at 3 V. 6 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. 7 GVDD PO Internally generated gate voltage supply. Not to be used as a supply or connected to any component other than a 1 µF X7R ceramic decoupling capacitor and the PLIMIT and GAIN/SLV resistor dividers. 8 GAIN/SLV I Selects Gain and selects between Master and Slave mode depending on pin voltage divider. 9 GND G Ground 10 LINP I Positive audio input for left channel. Biased at 3 V. Connect to GND for PBTL mode. 11 LINN I Negative audio input for left channel. Biased at 3 V. Connect to GND for PBTL mode. 12 MUTE I Mute signal for fast disable/enable of outputs (HIGH = outputs Hi-Z, LOW = outputs enabled). TTL logic levels with compliance to AVCC. 13 AM2 I AM Avoidance Frequency Selection 14 AM1 I AM Avoidance Frequency Selection 15 AM0 I AM Avoidance Frequency Selection 16 SYNC DIO Clock input/output for synchronizing multiple class-D devices. Direction determined by GAIN/SLV terminal. 17 AVCC P Analog Supply 18 PVCC P Power supply 19 PVCC P Power supply 20 BSNL BST Boot strap for negative left channel output, connect to 220 nF X5R, or better ceramic cap to OUTPL 21 OUTNL PO Negative left channel output 22 GND G Ground 23 OUTPL PO Positive left channel output 24 BSPL BST Boot strap for positive left channel output, connect to 220 nF X5R, or better ceramic cap to OUTNL 25 GND G Ground 26 BSNR BST Boot strap for negative right channel output, connect to 220 nF X5R, or better ceramic cap to OUTNR 27 OUTNR PO Negative right channel output 28 GND G Ground 29 OUTPR PO Positive right channel output 30 BSPR BST Boot strap for positive right channel output, connect to 220 nF X5R or better ceramic cap to OUTPR 31 PVCC P Power supply 32 PVCC P Power supply 33 PowerPAD G Connect to GND for best system performance. If not connected to GND, leave floating. (1) TYPE: DO = Digital Output, I = Analog Input, G = General Ground, PO = Power Output, BST = Boot Strap. 4 Submit Documentation Feedback Copyright © 2012–2015, Texas Instruments Incorporated Product Folder Links: TPA3116D2 TPA3118D2 TPA3130D2 |
