AD7545ALPZ Equivalent & Substitute Parts

Part Overview

The AD7545ALPZ is a 12-bit Digital to Analog Converter (DAC) manufactured by Analog Devices Inc., designed for data acquisition applications requiring single-channel analog output conversion. This surface-mount component operates with external voltage references and delivers current-mode unbuffered output with 1µs settling time. The part is actively produced and maintains full RoHS3 compliance, making it suitable for modern industrial and instrumentation designs. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, supply chain considerations, or design flexibility needs.

Substitute Part Grouping Explanation

Substitution of the AD7545ALPZ is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part AD7545AKPZ maintains identical specifications in the following key areas:

• 12-bit resolution with single D/A converter channel
• 1µs settling time and R-2R architecture
• Current-mode unbuffered output with parallel data interface
• External reference voltage configuration
• Dual supply voltage range (5V ~ 15V for both analog and digital)
• Identical INL/DNL performance (±0.5 LSB max, ±1 LSB max)
• 20-PLCC (9x9) surface-mount package with 20-LCC J-Lead configuration
• Full RoHS3 compliance and MSL Level 1 rating

Both parts share the same base product number (AD7545) and are manufactured by Analog Devices Inc. with Active product status. Substitution is valid when all electrical performance requirements and mechanical package specifications must be preserved.
