AD1674KRZ-REEL

Analog To Digital Converters (ADC) Overview

The AD1674KRZ-REEL is a 12-bit, 100 kSPS analog-to-digital converter manufactured by Analog Devices Inc. It features an integrated sample-and-hold amplifier (SHA) and operates within the 0 °C to +70 °C temperature range. The device utilizes a SAR architecture with a parallel digital interface and accepts single-ended inputs across four calibrated ranges: 0 V to +10 V, 0 V to +20 V, –5 V to +5 V, and –10 V to +10 V. Power supplies include +5 V logic and ±12 V or ±15 V analog rails. Key specifications include a full-scale error of 0.25% FSR, integral nonlinearity of ±0.5 LSB, and a signal-to-noise and distortion ratio of 70 dB.

Analog To Digital Converters (ADC) Feature Summary

• Integrated SHA supporting full Nyquist bandwidth without requiring wait-states
• Industry standard pinout compatible with AD574A and AD674A
• Flexible digital interface with three-state output buffers for microprocessor connection
• On-chip 10 V reference with external or internal reference options

Analog To Digital Converters (ADC) Applications

• Signal processing systems requiring AC and DC specifications
• Traditional DC measurement applications
• Microprocessor-based data acquisition systems
• Industrial control environments

Analog To Digital Converters (ADC) Procurement Notes

Verify that the suffix 'REEL' indicates tape and reel packaging rather than tube packaging. Confirm the K grade designation corresponds to the commercial 0 °C to +70 °C operating range. Ensure the specific revision level matches system requirements as specifications are subject to change without notice.

Analog To Digital Converters (ADC) Selection Notes

Select this component when industry-standard pin compatibility with legacy ADCs is required alongside improved conversion speeds. The K grade is suitable for commercial applications where operation above 70 °C is not needed. Verify power supply availability for ±12 V or ±15 V analog rails and +5 V logic.

Analog To Digital Converters (ADC) Part Context

The AD1674KRZ-REEL belongs to the AD1674 family of 12-bit ADCs. It is pin-compatible with the AD574A and AD674A but offers faster conversion rates due to its onboard sampling function. The KRZ variant specifically denotes the plastic SOIC package in tape and reel format for the K temperature grade.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements include other members of the AD1674 family such as AD1674JRZ for lower accuracy or AD1674BRZ for extended temperature ranges. Verify that substitute parts maintain the same package type and thermal characteristics.
