ADAS3023BCPZ

Analog To Digital Converters (ADC) Overview

The ADAS3023BCPZ is a complete 16-bit, eight-channel simultaneous sampling data acquisition system manufactured on Analog Devices' iCMOS high voltage process. It integrates low leakage track-and-hold circuits, a programmable gain instrumentation amplifier (PGIA) with 95 dB common-mode rejection, and a PulSAR SAR ADC. The device supports differential input ranges up to ±20.48 V using ±15 V supplies. Throughput 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 an internal 4.096 V reference, a 4-wire SPI-compatible interface, and operates within a −40°C to +85°C temperature range in a 40-lead LFCSP package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and temperature grade. Confirm that the required supply voltages match the ±15 V analog rails and 5 V digital logic levels specified for optimal performance. Ensure the host controller supports the required serial clock speeds and timing constraints for the SPI interface.

Analog To Digital Converters (ADC) Selection Notes

Select this component when simultaneous sampling of multiple channels is critical to avoid phase errors. Evaluate the required input voltage range against the available PGIA gains to ensure compatibility with the signal source. Consider the power supply complexity due to the requirement for ±15 V rails if interfacing with high-voltage signals directly.
