AD7890ANZ-10

ADCs/DACs - Special Purpose Overview

The AD7890ANZ-10 is an 8-channel, 12-bit data acquisition system fabricated in LC2MOS technology. It integrates a multiplexer, track/hold amplifier, SAR ADC, and 2.5 V reference on a single chip. Operating from a single 5 V supply, it supports ±10 V analog input ranges with a maximum conversion time of 5.9 μs. The device features a high-speed serial interface and draws 50 mW maximum power in normal mode. It is housed in a 24-lead PDIP package 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 to MUX OUT for external antialiasing filtering
• On-chip 2.5 V voltage reference and track/hold amplifier
• High-speed bidirectional serial interface compatible with microcontrollers and DSPs
• Low-power operation with 30 mW typical dissipation and 75 μW standby mode

ADCs/DACs - Special Purpose Applications

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

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'ANZ-10' against the manufacturer's current ordering guide to confirm availability and exact pinout compatibility. Ensure the application requires the ±10 V input range associated with this variant. Check RoHS compliance status as indicated in the latest datasheet revision C documentation.

ADCs/DACs - Special Purpose Selection Notes

Select the AD7890ANZ-10 when bipolar ±10 V input signals are required. Compare performance against the AD7890-4 (0 V to 4.096 V) or AD7890-2 (0 V to 2.5 V) if unipolar inputs suffice. Consider the PDIP-24 package constraints versus SOIC_W alternatives for PCB layout requirements.

ADCs/DACs - Special Purpose Part Context

This component belongs to the AD7890 family of monolithic data acquisition systems. It shares architectural similarities with variants like the AD7890ANZ-4 and AD7890ARZ-10, differing primarily in input voltage range and package type. The 'A' version denotes commercial temperature specifications (-40°C to +85°C).

ADCs/DACs - Special Purpose Replacement Considerations

Direct functional substitutes include other AD7890 variants such as AD7890ANZ-4 or AD7890BR-10REEL, provided the input voltage range matches the application needs. Verify package footprint compatibility between PDIP and SOIC packages if switching form factors.
