AD7819YRZ-REEL

Analog To Digital Converters (ADC) Overview

The AD7819YRZ-REEL is an 8-bit successive approximation analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It operates on a single supply voltage ranging from 2.7 V to 5.5 V and supports a maximum throughput of 200 kSPS with a conversion time of 4.5 µs. The device features an 8-bit parallel interface, an on-chip track-and-hold circuit, and an internal clock oscillator. It is housed in a 16-lead SOIC package and functions within a temperature range of -40°C to +125°C. Power consumption is 17.5 mW at 5 V during normal operation, significantly reduced via automatic power-down modes.

Analog To Digital Converters (ADC) Feature Summary

• Automatic power-down mode reduces average power consumption at lower throughput rates
• Microprocessor-compatible 8-bit parallel interface for easy system integration
• On-chip track-and-hold circuitry eliminates external sampling components
• Internal clock oscillator simplifies timing requirements

Analog To Digital Converters (ADC) Applications

• Battery-powered instrumentation systems
• Industrial process control data acquisition
• Portable measurement devices

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'REEL' indicates tape and reel packaging when sourcing. Confirm RoHS compliance status as manufacturing processes may change. Check for obsolescence notices or lifecycle status updates directly from Analog Devices before finalizing procurement plans.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring low-cost, single-supply 8-bit conversion with high speed. Ensure the microprocessor interface supports parallel data reading. Consider the automatic power-down feature if battery life is critical at moderate sampling rates.

Analog To Digital Converters (ADC) Part Context

This part belongs to the AD7819 family of 8-bit ADCs. It shares architectural similarities with other SAR converters but is distinguished by its specific parallel interface and integrated oscillator. It serves as a bridge between analog signals and digital processing units in cost-sensitive embedded designs.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements include the AD7819YR (tube) or AD7819YNZ (DIP). Verify that any substitute maintains the 2.7 V to 5.5 V operating range and 200 kSPS throughput specification.
