AD7892ARZ-3REEL7

Analog To Digital Converters (ADC) Overview

The AD7892ARZ-3REEL7 is a 12-bit successive approximation analog-to-digital converter (ADC) fabricated in LC2MOS technology. It operates from a single +5 V supply and achieves a throughput rate of 600 kSPS with a conversion time of 1.47 µs and an acquisition time of 200 ns. The device features an internal +2.5 V reference, an on-chip track/hold amplifier, and overvoltage protection allowing inputs up to ±7 V. It accepts a bipolar input range of ±2.5 V and provides flexible parallel or serial data output interfaces.

Analog To Digital Converters (ADC) Feature Summary

• Integrated signal scaling for direct handling of ±2.5 V analog inputs without external attenuation
• Versatile interface logic supporting both high-speed parallel and three-wire serial connections
• On-chip track/hold amplifier ensures accurate sampling at maximum throughput rates
• Internal voltage reference eliminates the need for external components in standard configurations

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring isolated signal conditioning
• Portable instrumentation powered by single-supply batteries
• Data acquisition modules interfacing with microcontrollers via serial ports
• Vibration monitoring and acoustic sensing applications

Analog To Digital Converters (ADC) Procurement Notes

Verify that the specific suffix 'REEL7' corresponds to the tape-and-reel packaging format required for automated surface-mount assembly. Confirm the 'A' grade designation meets the specified temperature range and accuracy requirements for the target environment before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-supply operation is mandatory alongside high-speed conversion capabilities. The AD7892-3 variant is specifically designed for bipolar ±2.5 V input ranges. Ensure the system design accommodates the 60 mW power dissipation typical for normal operation modes.

Analog To Digital Converters (ADC) Part Context

This part belongs to the AD7892 family of fast, low-power ADCs. The 'AR' package code indicates a 24-lead Small Outline Integrated Circuit (SOIC). The '3' suffix specifies the ±2.5 V input range and 600 kSPS speed class, distinguishing it from the ±10 V/±5 V (AD7892-1) or unipolar (AD7892-2) variants.

Analog To Digital Converters (ADC) Replacement Considerations

The AD7892BRZ-3REEL serves as a functional equivalent within the same product line, offering identical electrical performance but potentially differing in relative accuracy specifications.
