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.
