AD7581JN

ADCs/DACs - Special Purpose Overview

The AD7581JN 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 within a supply voltage range of +5V for digital logic and +/-17V for analog inputs. Key electrical specifications include a maximum linear error of 0.731%, a parallel interface type, and single-ended input configuration. It is housed in a 28-pin PDIP package and supports an operating temperature range up to 70°C.

• Industrial process control instrumentation
• General-purpose analog signal digitization

ADCs/DACs - Special Purpose Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as the provided data indicates non-compliance. Ensure the specific suffix 'JN' corresponds to the required commercial temperature grade and DIP-28 packaging before procurement.

ADCs/DACs - Special Purpose Selection Notes

Select this component when an 8-bit resolution with 8 multiplexed channels is sufficient for the application. Consider the +/-17V analog input range against standard 5V logic levels. Verify that the parallel interface and PDIP-28 form factor fit the target PCB layout constraints.

ADCs/DACs - Special Purpose Part Context

This part belongs to the AD7581 series of data acquisition systems. It serves as a lower-resolution alternative to higher-bit variants like the AD7582. The JN suffix typically denotes a commercial temperature range and plastic dual in-line package construction.

ADCs/DACs - Special Purpose Replacement Considerations

Direct pin-compatible replacements may include other parts from the AD758x family, such as the AD7581KNZ, though verification of temperature range and RoHS status is required. Cross-reference with Maxim Integrated MX7581 equivalents if available.
