AD7876BRZ

Overview

The AD7876BRZ is a complete monolithic 12-bit analog-to-digital converter featuring an internal track-and-hold amplifier and a buried Zener reference. It operates from ±5 V power supplies with a typical power dissipation of 60 mW. The device supports a sampling rate of 100 kS/s and accepts a bipolar input voltage range of ±10 V. Data output formats include parallel, byte, and serial interfaces, with a data access time of 57 ns. It is housed in a 24-pin SOIC package and functions within an industrial temperature range of -40°C to +85°C.

Feature Summary

Integrated 3 V buried Zener reference with external scaling capability for ±10 V operation
Versatile digital interface supporting parallel, byte, and serial data output modes
Laser-trimmed internal clock oscillator ensuring accurate conversion timing without external components

Applications

Data acquisition systems requiring high-speed 12-bit resolution
Industrial process control applications with bipolar signal inputs
Digital signal processing front-ends compatible with standard microprocessors

Procurement Notes

Verify the specific suffix BRZ indicates the industrial temperature grade (-40°C to +85°C) and SOIC package variant. Confirm RoHS compliance status and moisture sensitivity level prior to ordering. Ensure supply voltages match the required ±5 V specification for proper functionality.

Selection Notes

Select the AD7876BRZ when a bipolar ±10 V input range is required alongside 12-bit resolution. Compare against the AD7870 for ±3 V ranges or the AD7875 for unipolar 0 V to +5 V requirements. Consider interface flexibility needs when choosing between parallel and serial modes.

Part Context

The AD7876BRZ belongs to the AD7870/AD7875/AD7876 family of LC2MOS 12-bit sampling ADCs. While sharing core architecture and performance metrics, it is distinguished by its specific ±10 V input range capability. This variant complements the AD7870 and AD7875 within the same product line.
