AD7872KR

Overview

The AD7872KR 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, successive approximation register, and a 3 V buried Zener reference. It provides a serial digital interface with an 83 kSPS throughput rate and typical power dissipation of 50 mW. The K version supports an operating temperature range of 0°C to +70°C.

Feature Summary

Serial data output interface for microprocessor compatibility
Integrated track-and-hold amplifier with 2 μs acquisition time
Internal 3 V temperature-compensated voltage reference
Self-contained laser-trimmed clock oscillator

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 KR against official Analog Devices documentation to confirm the commercial temperature grade and package type. Ensure supply chain sources provide valid RoHS compliance certificates. Confirm that the ordering information matches the exact part number requirements for your design specifications.

Selection Notes

Select this component when a serial interface is required instead of parallel access. The AD7871 variant offers parallel and byte modes, whereas the AD7872 is strictly serial. Verify that the system timing accommodates the 57 ns data access time and the specific serial clock constraints defined in the datasheet.

Part Context

This device belongs to the AD7871/AD7872 family of fast, complete 14-bit sampling ADCs. Both parts share identical internal architecture and performance characteristics, differing primarily in their digital output configuration. The AD7872 specifically restricts operation to serial data transmission only.
