AD7890BRZ-10REEL

ADCs/DACs - Special Purpose Overview

The AD7890BRZ-10REEL is an 8-channel, 12-bit serial data acquisition system manufactured by Analog Devices Inc. It integrates a multiplexer, track/hold amplifier, ADC, and 2.5 V reference on a single chip. Operating from a single 5 V supply, it supports ±10 V input ranges with a maximum conversion time of 5.9 μs. The device features a high-speed serial interface, low power consumption (30 mW typical), and operates within a temperature range of -40°C to +85°C.

ADCs/DACs - Special Purpose Feature Summary

• Integrated 8-channel multiplexer with separate access for external antialiasing filtering
• High-speed serial interface compatible with microcontrollers and DSPs
• On-chip 2.5 V voltage reference and track/hold amplifier
• Low power operation: 30 mW typical in normal mode, 75 μW in standby

ADCs/DACs - Special Purpose Applications

• Industrial process control systems requiring multi-channel signal acquisition
• Data acquisition modules for factory automation
• Embedded measurement systems interfacing with digital signal processors

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'REEL' indicates tape-and-reel packaging when sourcing. Confirm the '-10' designation corresponds to the ±10 V input range variant. Ensure the 'B' version meets the required -40°C to +85°C operating temperature specifications for the target application environment.

ADCs/DACs - Special Purpose Selection Notes

Select this component for applications requiring an integrated solution for up to eight single-ended analog inputs. The ±10 V input range makes it suitable for standard industrial sensor signals. Consider the serial interface requirements and ensure the host processor can support the necessary clocking modes (self-clocking or external).

ADCs/DACs - Special Purpose Part Context

This part belongs to the AD7890 family of data acquisition systems. The 'B' version denotes the commercial temperature grade (-40°C to +85°C), while the '-10' suffix specifies the ±10 V input voltage range capability. The 'REEL' suffix indicates the manufacturing packaging format for automated assembly.

ADCs/DACs - Special Purpose Replacement Considerations

Direct replacements within the same family include other AD7890 variants with different input ranges (e.g., AD7890-4 for 0-4.096 V) or temperature grades (e.g., AD7890S for extended temperature). Verify pin compatibility and software register configurations when substituting.
