Product details
Overview
ADAS3023BCPZ from Analog Devices is a 16-bit, 8-channel simultaneous-sampling data acquisition system (DAS) integrating PGIA, SAR ADC, on-chip 4.096 V reference, and SPI/SPORT-compatible interface. It delivers 125 kSPS at 8 channels, ±20.48 V differential input range, >500 MΩ input impedance, and 95.0 dB common-mode rejection-enabling high-accuracy industrial voltage monitoring with minimal external circuitry.
For engineers reviewing the ADAS3023BCPZ datasheet, ADAS3023BCPZ pinout, ADAS3023BCPZ application, or ADAS3023BCPZ equivalent, key selection criteria include simultaneous sampling rate per channel count, differential input voltage range scalability via PGIA gain settings (0.2–1.6), internal reference stability (±5 ppm/°C), and LFCSP-40 thermal performance (θJA = 44.1°C/W) in harsh environments.
Technical Context
The ADAS3023BCPZ employs a charge redistribution PulSAR® SAR architecture with no pipeline latency, enabling immediate result availability post-conversion. Its integrated programmable gain instrumentation amplifier supports four differential input ranges (±2.56 V to ±20.48 V) and achieves 95.0 dB DC CMRR across all channels.
It uses iCMOS® high-voltage process technology to support ±15 V analog supplies (VDDH/VSSH), enabling direct connection to industrial sensors without level-shifting. The device features dual supply domains: high-voltage analog (±15 V), core analog/digital (5 V), and flexible I/O (1.8–5 V), with dedicated decoupling pins (ACAP, DCAP, RCAP) for noise-sensitive analog sections.
Key Specifications
