AD1672AP-REEL

Overview

The AD1672AP-REEL is a monolithic, single-supply 12-bit analog-to-digital converter operating at a maximum conversion rate of 3 MSPS. It integrates a high-performance sample-and-hold amplifier and a voltage reference within a 28-pin PLCC package. The device utilizes a multistage pipelined architecture with output error correction logic to ensure no missing codes across the full operating temperature range of -40°C to +85°C. Power consumption is specified at 240 mW under standard conditions. Digital I/Os are compatible with both +5 V and +3.3 V logic families.

Feature Summary

• Integrates a complete sampling function including an on-chip sample-and-hold amplifier and voltage reference.
• Features pin-configurable input voltage ranges supporting unipolar and bipolar signal acquisition.
• Includes an out-of-range indicator to detect overflow conditions during operation.

Applications

• Communications systems requiring high-speed data acquisition
• Imaging applications utilizing rapid transient signal capture
• Medical instrumentation demanding precise analog-to-digital conversion

Procurement Notes

Verify component authenticity through authorized distribution channels due to obsolete status. Confirm package integrity and lead condition prior to installation. Ensure handling procedures comply with electrostatic discharge sensitivity requirements to prevent performance degradation or functional loss during assembly.

Selection Notes

Evaluate power supply compatibility for VCC, VDD, and DRVDD pins to match system logic levels. Assess thermal management requirements given the 240 mW power dissipation specification. Consider external reference options if stricter accuracy or drift characteristics are required compared to the onboard bandgap reference.
