AD7892ARZ-3

Overview

The AD7892ARZ-3 is a 12-bit successive approximation analog-to-digital converter fabricated in LC2MOS technology. It operates from a single +5 V supply with typical power consumption of 60 mW. The device features an on-chip track/hold amplifier and internal +2.5 V reference. Input range is ±2.5 V with overvoltage protection up to ±7 V. Throughput rate reaches 600 kSPS with conversion time of 1.47 µs and acquisition time of 200 ns. It supports parallel and serial interfaces in a 24-lead SOIC package.

Feature Summary

• Integrated signal scaling, track/hold, reference, and ADC functions on a single chip
• Flexible interface options supporting both high-speed parallel and serial connections
• On-chip +2.5 V reference with option for external reference input
• Overvoltage protection on analog inputs for robust operation

Applications

• Portable instrumentation systems requiring low power consumption
• Microprocessor-based data acquisition systems
• Digital signal processor interfacing applications

Procurement Notes

Verify the specific suffix 'ARZ-3' corresponds to the Analog Devices Inc. manufacturer part number. Confirm the package type is 24-lead SOIC and the temperature range is commercial (-40°C to +85°C). Ensure the input range specification matches the ±2.5 V requirement for this variant before procurement.

Selection Notes

Select the AD7892ARZ-3 when a ±2.5 V input range is required with overvoltage protection. Choose this model for applications needing 600 kSPS throughput rates. Consider the parallel or serial interface options based on system bus architecture requirements. Verify power supply constraints align with the single +5 V operation specification.

Part Context

The AD7892 belongs to Analog Devices' LC2MOS family of mixed-signal converters. This series combines precision bipolar circuits with low-power CMOS logic. The ARZ-3 variant specifically targets applications requiring ±2.5 V input ranges with high speed and low power consumption characteristics.
