Precision A/D Converters < 20 MSPS
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
The AD7768-1 is a low power, high performance, Σ-Δ analog to digital converter (ADC), with a Σ-Δ modulator and digital filter for precision conversion of both ac and dc signals.
The LTC2358-18 is an 18-bit, low noise 8-channel simultaneous sampling successive approximation register (SAR) ADC with buffered differential, wide common mode range picoamp inputs.
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.
