AD7715ARZ-5REEL

Overview

The AD7715ARZ-5REEL is a single-channel, 16-bit Sigma-Delta analog-to-digital converter manufactured by Analog Devices. It operates with an analog supply voltage of 5 V and a digital supply range of 3 V to 5.25 V. The device features a differential input architecture and supports 3-Wire, Microwire, and SPI serial interfaces. It provides a maximum sampling rate of 500 samples per second. Key static performance metrics include an integral nonlinearity of ±0.0015% FSR and a gain error of ±0.0015% FSR. Power consumption is specified at 9.5 mW under typical operating conditions.

Feature Summary

• Integrates a programmable gain front end capable of accepting low-level signals directly from transducers without external conditioning.
• Includes on-chip self-calibration and system calibration options to eliminate zero-scale and full-scale errors.
• Features a charge-balancing ADC architecture with a digital filter offering programmable output update rates.

Applications

• Pressure measurement systems
• Temperature measurement applications
• Smart transmitter implementations

Procurement Notes

Verify the specific suffix 'REEL' indicates tape-and-reel packaging when placing orders. Confirm that the '-5' designation corresponds to the 5 V analog supply variant. Ensure compatibility with the EVAL-AD7715-3EBZ development kit if hardware validation is required for the design phase.

Selection Notes

Select this component for single-channel applications requiring high precision at low data rates. The 16-bit resolution and low noise characteristics make it suitable for bridge sensor interfaces. Verify that the available serial interface protocols match the host microcontroller or DSP capabilities.

Part Context

This part belongs to the AD7715 family of complete analog front ends designed for low-frequency measurement. It utilizes Sigma-Delta conversion techniques to achieve high accuracy. The device integrates the modulator, digital filter, and reference inputs into a single package to simplify system design.

Replacement Considerations

The AD7715ARUZ-5REEL7 serves as a pin-compatible alternative in the TSSOP-16 package. The AD7715ANZ-3 offers the same functionality in a PDIP-16 through-hole package. Verify package dimensions and lead configurations before substituting these variants.
