ADAS3023BCPZ-RL7

Analog To Digital Converters (ADC) Overview

The ADAS3023BCPZ-RL7 is a complete 16-bit, eight-channel simultaneous sampling data acquisition system manufactured on Analog Devices' proprietary iCMOS high voltage industrial process. It integrates low leakage track-and-hold circuits, programmable gain instrumentation amplifiers (PGIA), and a PulSAR SAR ADC. The device supports differential input ranges up to ±20.48 V with ±15 V supplies. Sampling rates vary by channel count: 500 kSPS for two channels, 250 kSPS for four, 167 kSPS for six, and 125 kSPS for eight channels. It features a serial SPI-compatible interface, internal reference, and operates from −40°C to +85°C in a 40-lead LFCSP package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix RL7 corresponds to tape and reel packaging requirements before procurement. Confirm that the host system provides the necessary dual supply voltages of ±15 V for the analog section and appropriate logic levels for the digital interface. Ensure the application design accounts for the specified thermal resistance characteristics of the LFCSP package.

Analog To Digital Converters (ADC) Selection Notes

Select this component when high channel count and simultaneous sampling are required without external multiplexing latency. Evaluate the PGIA gain settings against the expected input signal amplitudes to optimize dynamic range. Consider the power supply requirements and ensure adequate decoupling for the analog and digital domains to maintain specified noise performance.

Analog To Digital Converters (ADC) Part Context
