AD7872JNZ

Overview

The AD7872JNZ is a complete monolithic 14-bit analog-to-digital converter (ADC) fabricated in LC2MOS technology. It operates from ±5 V power supplies and accepts bipolar input signals within the ±3 V range. The device features an internal laser-trimmed clock, track-and-hold amplifier, and a 3 V buried Zener reference. It provides an 83 kSPS throughput rate with a typical power dissipation of 50 mW. The AD7872JNZ utilizes a serial digital interface for data output.

Feature Summary

• Serial-only data output architecture
• Integrated on-chip clock oscillator
• Internal 3 V voltage reference
• Bipolar signal conversion capability

Applications

• Digital signal processing systems
• High-speed modem applications
• Speech recognition and synthesis equipment
• Spectrum analysis instruments
• DSP servo control loops

Procurement Notes

Verify the specific suffix JNZ against official documentation to confirm the commercial temperature range and package type. Ensure that the ordering information matches the exact pinout and electrical specifications required for the target application design.

Selection Notes

Select this component when a single-channel 14-bit resolution is required with a serial interface. It is suitable for designs needing low power consumption and integrated reference circuitry without external timing components. Verify compatibility with the host microprocessor's serial communication protocols.

Part Context

This part belongs to the AD7871/AD7872 family of fast, complete 14-bit sampling ADCs. While the AD7871 offers parallel and byte interfaces, the AD7872 variant is restricted to serial data transmission only. Both share identical core analog performance characteristics and internal architectures.

Replacement Considerations

The AD7871KRZ is listed as a substitute part number by distributors.
