AD9761ARS Equivalent & Substitute Parts

Part Overview

The AD9761ARS is a 10-bit digital-to-analog converter (DAC) manufactured by Analog Devices Inc., designed for data acquisition applications requiring dual-channel current output conversion. This active product operates across analog supply voltages of 3V to 5.5V and digital supply voltages of 2.7V to 5.5V, with a typical settling time of 35 nanoseconds. The component is housed in a 28-SSOP surface-mount package and features differential current outputs with external and internal reference capability. Substitute parts are identified when all critical electrical and mechanical parameters remain identical, ensuring direct functional equivalence without design modification.

Substitute Part Grouping Explanation

Substitution of the AD9761ARS is determined by strict equivalence across all critical parameters. The substitute part AD9761ARSZ maintains identical electrical specifications including 10-bit resolution, dual-channel configuration, 35ns settling time, current-unbuffered output topology, differential output capability, parallel data interface, and dual reference support (external and internal). Supply voltage ranges, INL/DNL performance, current-source architecture, and operating temperature range are identical. Both parts are housed in the 28-SSOP surface-mount package with matching mechanical dimensions. Compliance certifications including ROHS3, MSL Level 1, and REACH status are equivalent. The substitution is valid based on complete parameter alignment across electrical performance, interface characteristics, packaging, and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

Both AD9761ARS and AD9761ARSZ are active products from Analog Devices Inc. with identical electrical and mechanical specifications. Selection between these parts may be based on inventory availability or supplier preference, as no technical differentiation exists. Both components meet ROHS3 compliance requirements and carry REACH Unaffected status, making them suitable for applications subject to environmental and regulatory constraints. The MSL Level 1 rating indicates unlimited moisture sensitivity protection, supporting standard PCB assembly processes without special handling requirements. Either part is suitable for direct substitution in existing designs without circuit modification or re-qualification.
