ADAS3022BSTZ

Analog To Digital Converters (ADC) Overview

The ADAS3022BSTZ is a complete 16-bit, 1 MSPS data acquisition system manufactured on Analog Devices' proprietary iCMOS high voltage industrial process. It integrates an 8-channel low leakage multiplexer, a programmable gain instrumentation amplifier (PGIA) with >100 dB common-mode rejection, a precision 4.096 V reference, and a 16-bit SAR ADC. The device supports differential input ranges up to ±24.576 V using ±15 V supplies. It features a serial 4-wire SPI-compatible interface operating at 1.8 V to 5 V logic levels. Available in LFCSP and LQFP packages, it operates within the −40°C to +85°C industrial temperature range.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific package variant required for the design, as the ADAS3022 family includes both LFCSP and LQFP options. Confirm that the ordering suffix matches the intended physical footprint and pinout configuration. Ensure supply voltages align with the specified requirements for proper operation of the integrated high-voltage analog front end.

Analog To Digital Converters (ADC) Selection Notes

Select this component when designing systems requiring high channel counts with simultaneous signal conditioning and digitization. The integrated PGIA eliminates the need for external amplifiers, simplifying board layout. Consider the power consumption characteristics relative to the sampling rate, as current draw scales linearly with throughput. Verify compatibility with the host microcontroller's serial interface timing constraints.

Analog To Digital Converters (ADC) Part Context

The ADAS3022 belongs to the ADAS302x series of data acquisition systems from Analog Devices. This series is designed to simplify the design of advanced industrial data acquisition systems by consolidating multiple discrete components into a single highly integrated solution. The BSTZ suffix typically denotes a specific package and tape/reel configuration within the broader product line.

Analog To Digital Converters (ADC) Replacement Considerations

Direct replacements within the same family include the ADAS3022BCPZ and ADAS3022BSTZ variants, which share identical electrical specifications but differ in packaging. Cross-family alternatives may require significant redesign due to differences in integration levels and pinouts.
