DAC12 Introduction

25.1 DAC12 Introduction

The DAC12 module is a 12-bit voltage-output DAC. The DAC12 can be configured in 8-bit or 12-bit mode

and may be used in conjunction with the DMA controller. When multiple DAC12 modules are present, they

may be grouped together for synchronous update operation.

Features of the DAC12 include:

• 12-bit monotonic output

• 8-bit or 12-bit voltage output resolution

• Programmable settling time vs power consumption

• Internal or external reference selection

• Straight binary or 2s compliment data format

• Self-calibration option for offset correction

• Synchronized update capability for multiple DAC12 modules

NOTE: Multiple DAC12 Modules

Some devices may integrate more than one DAC12 module. If more than one DAC12 is

present on a device, the multiple DAC12 modules operate identically.

Throughout this chapter, nomenclature appears such as DAC12_xDAT or DAC12_xCTL to

describe register names. When this occurs, the x is used to indicate which DAC12 module is

being discussed. In cases where operation is identical, the register is simply referred to as

DAC12_xCTL.

The block diagram of the DAC12 module is shown in Figure 25-1.
