17 / 306 page  6.2 Pin Attributes Table 6-1. Pin Attributes SIGNAL NAME MUX POSITION 337 176 PIN TYPE DESCRIPTION ANALOG ADCIN14 T4 44 I Input 14 to all ADCs. This pin can be used as a general purpose ADCIN pin or it can be used to calibrate all ADCs together (either single-ended or differential) from an external reference CMPIN4P I Comparator 4 positive input ADCIN15 U4 45 I Input 15 to all ADCs. This pin can be used as a general purpose ADCIN pin or it can be used to calibrate all ADCs together (either single-ended or differential) from an external reference CMPIN4N I Comparator 4 negative input ADCINA0 U1 43 I ADC-A Input 0. There is a 50-kΩ internal pulldown on this pin in both an ADC input or DAC output mode which cannot be disabled. DACOUTA O Buffered DAC-A Output. ADCINA1 T1 42 I ADC-A Input 1. There is a 50-kΩ internal pulldown on this pin in both an ADC input or DAC output mode which cannot be disabled. DACOUTB O Buffered DAC-B Output. ADCINA2 U2 41 I ADC-A Input 2 CMPIN1P I Comparator 1 positive input ADCINA3 T2 40 I ADC-A Input 3 CMPIN1N I Comparator 1 negative input ADCINA4 U3 39 I ADC-A Input 4 CMPIN2P I Comparator 2 positive input ADCINA5 T3 38 I ADC-A Input 5 CMPIN2N I Comparator 2 negative input ADCINB0 V2 46 I ADC-B Input 0. There is a 100-pF capacitor to VSSA on this pin whether used for ADC input or DAC reference which cannot be disabled. If this pin is being used as a reference for the on-chip DACs, place at least a 1-µF capacitor on this pin. VDAC I Optional external reference voltage for on-chip DACs. ADCINB1 W2 47 I ADC-B Input 1. There is a 50-kΩ internal pulldown on this pin in both an ADC input or DAC output mode which cannot be disabled. DACOUTC O Buffered DAC-C Output. ADCINB2 V3 48 I ADC-B Input 2 CMPIN3P I Comparator 3 positive input ADCINB3 W3 49 I ADC-B Input 3 CMPIN3N I Comparator 3 negative input ADCINB4 V4 I ADC-B Input 4 ADCINB5 W4 I ADC-B Input 5 ADCINC2 R3 31 I ADC-C Input 2 CMPIN6P I Comparator 6 positive input ADCINC3 P3 30 I ADC-C Input 3 CMPIN6N I Comparator 6 negative input www.ti.com TMS320F28388D, TMS320F28386D, TMS320F28386D-Q1 TMS320F28384D, TMS320F28384D-Q1, TMS320F28388S TMS320F28386S, TMS320F28386S-Q1, TMS320F28384S, TMS320F28384S-Q1 SPRSP14D – MAY 2019 – REVISED FEBRUARY 2021 Copyright © 2021 Texas Instruments Incorporated Submit Document Feedback 17 Product Folder Links: TMS320F28388D TMS320F28386D TMS320F28386D-Q1 TMS320F28384D TMS320F28384D-Q1 TMS320F28388S TMS320F28386S TMS320F28386S-Q1 TMS320F28384S TMS320F28384S-Q1 |
