AD7581JNZ

ADCs/DACs - Special Purpose Overview

The AD7581JNZ is an 8-bit, 8-channel analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It utilizes a successive approximation architecture and features CMOS technology compatible with microprocessors. The device operates on a single +5 V supply and includes an internal clock oscillator. Key electrical specifications include a maximum linear error of 0.731% and an input voltage range spanning from -17 V to +17 V. It is housed in a 28-lead DIP package.

• CMOS uP-Compatible 8-Bit ADC
• 8 Analog Input Channels
• Internal Clock Oscillator
• Single +5 V Supply Operation

ADCs/DACs - Special Purpose Applications

• Industrial Process Control
• Data Acquisition Systems
• Motor Control

ADCs/DACs - Special Purpose Procurement Notes

Verify the RoHS compliance status for the AD7581JNZ variant, as documentation indicates non-compliance for similar leaded packages. Confirm the specific ordering suffix requirements for lead-free versions if environmental regulations apply to the target deployment.

ADCs/DACs - Special Purpose Selection Notes

Select this component when an 8-bit resolution with multiple input channels is required. Ensure the application supports the specified ±17 V input range and that the 0.731% linearity meets system accuracy constraints. Verify compatibility with the 28-pin DIP footprint during PCB layout.

ADCs/DACs - Special Purpose Part Context

This part belongs to the AD7581 family of multiplexed ADCs. It shares architectural similarities with other CMOS ADCs from Analog Devices but is distinct in its specific pin count and channel configuration compared to lower-density variants.

ADCs/DACs - Special Purpose Replacement Considerations

Check for direct pin-compatible substitutes within the AD758x series or newer generations such as the AD7582/AD7583 if higher resolution is needed. Verify that any replacement maintains the same 28-lead DIP package and logic interface compatibility.
