Data converter circuits

Analog-to-digital converter (ADC) and digital-to-analog converter (DAC) circuits that can be quickly modified to meet your specific design needs

Each data converter circuit below includes step-by-step instructions with formulas allowing you to adapt the circuit to meet your unique design requirements. We've provided at least one recommended data converter for each circuit, but you can easily swap it with another device if you've found one that fits better with your design. Our circuits require a basic understanding of data converter concepts, so if you are new to data converter design, we highly recommend reviewing our TI Precision Labs (TIPL) training series.

Analog-to-digital converter (ADC) circuits

Low-power, small size, and cost optimized circuits

This section emphasizes low power ADC and amplifier circuits.  Often these circuits total power dissipation is a function of the sampling rate and the documentation will explain this trade off.  Frequently, these circuits also use a smaller physical PCB area, so often an example PCB layout and associated PCB area is covered in the document.

Commonly used auxiliary circuits

This section covers circuits that are commonly used with ADC systems.  For example, a power supply design that shows how to generate a -0.3V negative supply for an ADC drive amplifier is covered.  Other power supply options and ADC reverence drive circuits are also covered.

Audio outputs

Circuits and design techniques for high-performance audio systems, optimizing signal-to Noise ratio (SNR), total-harmonic-distortion (THD), and other AC specifications critical for audio applications.

Auxiliary and biasing circuits

Programmable open or closed loop voltage or current sources commonly used in adaptive voltage scaling, comparator, sensor excitation, or other calibration and biasing applications.

Current sources

High-side, low-side, and bi-directional current source or sink circuits commonly used for both control and biasing applications.

Voltage sources

High-voltage and low-voltage single-ended or differential circuits along with options for high-current drive, capacitive load compensation, and positive and negative sense connections.
