Description

Data Acquisition ADCs/DACs - Specialised 20-Bit, 8-channel Sim Sampling DAQ System

AD4858 Data Acquisition System (DAS)

Analog Devices' AD4858 is a high-performance, buffered, simultaneous sampling Data Acquisition System (DAS) featuring configurable SoftSpan ranges for each channel.

Key Features:

• Performance: The AD4858 features an 11 MHz bandwidth, picoamp input analog buffers, and a 120 dB common-mode rejection ratio (CMRR). This enables direct digitization of input signals with varying swings on INx+ and INx−.
• Precision: With ±160 μV integral nonlinearity (INL), no missing codes at 20 bits, a 97.2 dB signal-to-noise ratio (SNR), and a 111.4 dB dynamic range (DR), it is ideal for high accuracy, throughput, and precision applications.
• Flexibility: It supports 24-bit oversampling for enhanced SNR and dynamic range. Per-channel offset, gain, and phase adjustments allow for calibration and removal of system-level errors before data acquisition.
• Digital Interface: The AD4858 features a serial peripheral interface (SPI) register configuration bus (0.9 V to 5.25 V) and supports both LVDS and CMOS data output buses. Users can optimize bus width and throughput by employing between one and eight lines of data output in CMOS mode.
• Evaluation Kit: The EVAL-AD4858FMCZ evaluation kit demonstrates the AD4858's performance and provides access to various configuration options via an easy-to-use ACE plug-in graphical interface.
