Analog Devices provides an unrivalled portfolio for precision A/D converters. When you select an ADI precision ADC, you are selecting from the industry leading portfolio in ac and dc performance, power, speed and size, with products ranging from 8-bit to 32-bit resolution. ADI champions ease of use, with ever increasing emphasis on helping our customers to more quickly arrive at their end design objective, at a component level and signal chain level. Choose from a comprehensive suite of tools to simplify design in from selection to prototyping. Products are available in a range of architectures:
- SAR—Successive Approximation ADCs
- Σ-Δ Modulators
- Isolated ADCs
AD4111
AD4111 is a multi-channel, low power, low noise, 24-bit sigma-delta ADC that integrates an analog front end for fully differential or single-ended, high impedance bipolar, +/-10 V voltage inputs, and 0 mA to 20 mA current inputs.
AD7380
AD7380 is a 16-bit dual simultaneous sampling, high speed, low power, successive approximation register (SAR) ADC that operates from a 3.0 V to 3.6 V power supply and features throughput rates up to 4 MSPS.
AD4020
The AD4020 is a low noise, low power, 20-bit, 1.8 MSPS precision successive approximation register (SAR) analog-to-digital converter (ADC). It incorporates ease of use features that lower the signal chain power, reduce signal chain complexity, and enable higher channel density.

Linear & Precision Technology: New Product Upgrades
With the industry’s broadest portfolio of op amps, precision converters (ADCs and DACs), digital potentiometers, temperature sensors, voltage references, switches, and multiplexers, Analog Devices can help solve your toughest design challenges. ADI offers over 1000 precision linear ICs, outstanding customer support, and a full complement of precision design and development resources to meet any signal chain design demand.
Explore how we cover the signal chain in Power Management and Voltage References.
Using DIE products in your signal chain design
For space constrained designs, ADI offers die solutions for many products in our portfolio. Our team develops die solutions for precision converters for both:
- Functional CHIPS model – verified to be functional at Ambient temperature.
- KGD – Known Good Die guaranteed to meet Datasheet specifications
Both Die options can be shipped in Die on Film, Waffle pack or Tape & Reel.
Explore ADI’s precision ADC Die Portfolio
If you see a product that does not offer Die packaging, contact your ADI sales representative to explore how ADI can meet your needs. If you’re interested in system-in-package (SiP) technology, please see our Precision Signal Chain μModule solutions page.
Condition-based Monitoring (CbM) Development Platforms
Developing accurate, reliable condition monitoring solutions for industrial assets requires a combination of technologies and design considerations to capture and convert critical signals into actionable insights. Our platforms enable diagnostic and predictive maintenance solutions for accelerated sensor data collection.
Precision Technology Selection Guide
ADI’s Precision Technology Selection Guide easily enables selection of the right components for across the entire precision signal chain, from amplifiers, switches, analog-to-digital converters (ADCs), digital-to-analog converters (DACs), voltage references, and power management devices.
Precision ADC Driver Tool
A specialized simulation environment where you can quickly determine the impact of the driver and RC filter on the performance of an ADC signal chain.
Virtual Eval
Accelerate precision ADC product selection and evaluation with Virtual Eval. Configure operating conditions and simulate crucial part performance characteristics within seconds, including noise, distortion, frequency response plots, timing diagrams, FFTs and more.
AD7606x Software Model
The AD7606x Software Model enables users to try different configurations for AD7606, AD7606B, AD7608 and AD7609 : sampling rate, RC filtering, oversampling, calibration; and analyze frequency response, noise performance, interface timing or power consumption, among others.
