AD774BBRZ

Overview

The AD774BBRZ is a 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Analog Devices Inc. It features two single-ended input channels and utilizes an internal reference voltage. The device operates with an analog supply voltage range of ±11.4V to 16.5V and a digital supply voltage of 5V. It supports a sampling rate of 125 kS/s and offers a typical integral nonlinearity (INL) of ±0.5 LSB. The component is housed in a 28-SOIC surface-mount package and functions within a temperature range of -40°C to +85°C.

Feature Summary

• 12-bit resolution with SAR architecture
• Two single-ended input channels
• Internal reference voltage capability
• Parallel data interface

Applications

• Industrial process control systems
• Data acquisition modules
• Portable instrumentation

Procurement Notes

Verify the specific suffix 'BRZ' corresponds to the tube packaging format as indicated in distributor records. Confirm RoHS3 compliance status for environmental regulations. Check moisture sensitivity level (MSL 3) requirements for storage and handling procedures prior to assembly.

Selection Notes

Select this component when dual-channel 12-bit conversion is required with parallel interfacing. Ensure the system can accommodate the wide analog supply voltage range up to 16.5V. Verify that the 28-SOIC footprint fits the PCB layout constraints compared to other pin-count options in the AD774B family.

Part Context

This part belongs to the AD774B series, which includes variants like the AD674B. The AD774B specifically denotes the 12-bit resolution version with enhanced performance characteristics over earlier generations. The 'BRZ' suffix typically indicates a lead-free, RoHS-compliant variant in the SOIC-28 package.

Replacement Considerations

The MAX174AEWI+ is listed as a similar alternative. Verify pin compatibility and electrical parameter alignment before substitution.
