7.9.2.1.1 Features

The core of the ADC contains a single 12-bit converter fed by two sample-and-hold circuits. The sample-and-hold circuits can be sampled simultaneously or sequentially. These, in turn, are fed by a total of up to 16 analog input channels. The converter can be configured to run with an internal band-gap reference to create true-voltage based conversions or with a pair of external voltage references (VREFHI/VREFLO) to create ratiometric-based conversions.

Contrary to previous ADC types, this ADC is not sequencer-based. It is easy for the user to create a series of conversions from a single trigger. However, the basic principle of operation is centered around the configurations of individual conversions, called SOCs, or Start-Of-Conversions.

Functions of the ADC module include:

  • 12-bit ADC core with built-in dual sample-and-hold (S/H)
  • Simultaneous sampling or sequential sampling modes
  • Full range analog input: 0 V to 3.3 V fixed, or VREFHI/VREFLO ratiometric. The digital value of the input analog voltage is derived by:
    • Internal Reference (VREFLO = VSSA. VREFHI must not exceed VDDA when using either internal or external reference modes.)
      GUID-FA0F7399-5CAD-4B73-AE0D-74950ED8D1E6-low.gif
    • External Reference (VREFHI/VREFLO connected to external references. VREFHI must not exceed VDDA when using either internal or external reference modes.)
      GUID-FD391025-6774-489F-9DC7-C2408BC7190F-low.gif
  • Up to 16-channel, multiplexed inputs
  • 16 SOCs, configurable for trigger, sample window, and channel
  • 16 result registers (individually addressable) to store conversion values
  • Multiple trigger sources
    • S/W – software immediate start
    • ePWM 1–7
    • GPIO XINT2
    • CPU Timers 0/1/2
    • ADCINT1/2
  • 9 flexible PIE interrupts, can configure interrupt request after any conversion

ADC Connections if the ADC is Not Used

TI recommends keeping the connections for the analog power pins, even if the ADC is not used. Following is a summary of how the ADC pins should be connected, if the ADC is not used in an application:

  • VDDA – Connect to VDDIO
  • VSSA – Connect to VSS
  • VREFLO – Connect to VSS
  • ADCINAn, ADCINBn, VREFHI – Connect to VSSA

When the ADC module is used in an application, unused ADC input pins should be connected to analog ground (VSSA).

Note:

Unused ADCIN pins that are multiplexed with AIO function should not be directly connected to analog ground. They should be grounded through a 1-kΩ resistor. This is to prevent an errant code from configuring these pins as AIO outputs and driving grounded pins to a logic-high state.

When the ADC is not used, be sure that the clock to the ADC module is not turned on to realize power savings.
