AD7876BRZ-REEL7

Overview

The AD7876BRZ-REEL7 is a monolithic 12-bit successive approximation analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It operates from ±5 V power supplies and features an internal laser-trimmed clock, track-and-hold amplifier, and 3 V reference. The device accepts single-ended analog input signals within a ±10 V range. Data output formats include parallel, byte, and serial interfaces. Key electrical specifications include a maximum conversion time of 8 μs, a typical power dissipation of 60 mW, and a data access time of 57 ns. The component is housed in a 24-pin SOIC package and supports an operating temperature range of -40°C to +85°C.

Feature Summary

• Integrated 12-bit SAR architecture with on-chip track-and-hold amplifier and buried Zener reference.
• Versatile digital interface supporting parallel, byte, and serial data output modes.
• Internal laser-trimmed clock oscillator eliminates the need for external timing components.

Applications

• Data acquisition systems requiring 12-bit resolution.
• Industrial process control applications.
• Instrumentation and measurement equipment.

Procurement Notes

Verify the specific suffix REEL7 indicates reel packaging when sourcing. Confirm the B grade corresponds to the industrial temperature range of -40°C to +85°C. Ensure compatibility with ±5 V supply rails and check pinout alignment for the 24-SOIC footprint during integration.

Selection Notes

Select this model for applications requiring a ±10 V input range. Compare against AD7870 for ±3 V inputs or AD7875 for unipolar ranges. Verify that the 100 kHz sampling rate and 57 ns access time meet system throughput requirements.

Part Context

This component belongs to the AD7870/AD7875/AD7876 family of complete 12-bit ADCs. The AD7876 variant is distinguished by its ±10 V analog input capability, whereas other family members support different voltage ranges. All variants share the same core architecture and interface logic.
