Analog Signals (continued) SIGNAL NAME DESCRIPTION PIN TYPE GPIO 337 BGA 176 Pin CMPIN4P Comparator 4 positive input I T4 44 CMPIN5N Comparator 5 negative input I P4 CMPIN5P Comparator 5 positive input I R4 29 CMPIN6N Comparator 6 negative input I P3 30 CMPIN6P Comparator 6 positive input I R3 31 CMPIN7N Comparator 7 negative input I U5 57 CMPIN7P Comparator 7 positive input I T5 56 CMPIN8N Comparator 8 negative input I U6 59 CMPIN8P Comparator 8 positive input I T6 58 DACOUTA Buffered DAC-A Output. O U1 43 DACOUTB Buffered DAC-B Output. O T1 42 DACOUTC Buffered DAC-C Output. O W2 47 VDAC Optional external reference voltage for on-chip DACs. I V2 46 VREFHIA ADC-A high reference. This voltage must be driven into the pin from external circuitry. Place at least a 2.2- µF capacitor on this pin for the 12-bit mode, or at least a 22-µF capacitor for the 16-bit mode. This capacitor should be placed as close to the device as possible between the VREFHIA and VREFLOA pins. NOTE: Do not load this pin externally I V1 37 VREFHIB ADC-B high reference. This voltage must be driven into the pin from external circuitry. Place at least a 2.2- µF capacitor on this pin for the 12-bit mode, or at least a 22-µF capacitor for the 16-bit mode. This capacitor should be placed as close to the device as possible between the VREFHIB and VREFLOB pins. NOTE: Do not load this pin externally I W5 53 VREFHIC ADC-C high reference. This voltage must be driven into the pin from external circuitry. Place at least a 2.2- µF capacitor on this pin for the 12-bit mode, or at least a 22-µF capacitor for the 16-bit mode. This capacitor should be placed as close to the device as possible between the VREFHIC and VREFLOC pins. NOTE: Do not load this pin externally I R1 35 VREFHID ADC-D high reference. This voltage must be driven into the pin from external circuitry. Place at least a 2.2- µF capacitor on this pin for the 12-bit mode, or at least a 22-µF capacitor for the 16-bit mode. This capacitor should be placed as close to the device as possible between the VREFHID and VREFLOD pins. NOTE: Do not load this pin externally I V5 55 VREFLOA ADC-A Low Reference I R2 33 VREFLOB ADC-B Low Reference I V6 50 VREFLOC ADC-C Low Reference I P2 32 VREFLOD ADC-D Low Reference I W6 51 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 51 Product Folder Links: TMS320F28388D TMS320F28386D TMS320F28386D-Q1 TMS320F28384D TMS320F28384D-Q1 TMS320F28388S TMS320F28386S TMS320F28386S-Q1 TMS320F28384S TMS320F28384S-Q1 |
