Precision A/D Converters
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 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 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.
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.
