1 Introduction

Before selecting a DAC, assess the absolute system requirements:

  • What are the key specifications? – Output voltage range, current drive capability, current drive, and communication interface are important considerations.
  • Is a high resolution necessary? – Some applications achieve sufficient performance with lower bit resolutions, reducing the DAC power and cost.
  • What is the bandwidth of the DAC? – The minimum time needed for DAC output changes is related to output slew rate limitations and settling time.
  • What integrated features reduce system complexity? – Integrated voltage reference, diagnostic features such as output monitoring and STATUS alarms, or integrated analog-to-digital converters (ADC) can simplify the design and reduce bill-of material (BOM).
  • What device rating does the target industry require? – AEC-Q100 for automotive (Q1) or radiation hardened for space applications (SP).
