AD5535ABCZ Equivalent & Substitute Parts

Part Overview

The AD5535ABCZ is a 14-bit Digital to Analog Converter (DAC) with 32 independent D/A converter channels, designed for high-density data acquisition applications. It features voltage-buffered output, external reference capability, and operates across a wide digital supply voltage range of 2.7V to 5.25V with a 5V analog supply. The device is packaged in a 124-CSPBGA (15x15) ball grid array format for surface mount applications.

The AD5535ABCZ is currently classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain reliability, and support legacy system maintenance or redesign initiatives.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AD5535ABCZ is determined by strict equivalence across the following critical parameters:

• Resolution and Channel Count: 14-bit resolution with 32 independent D/A converters
• Output Characteristics: Voltage-buffered output with no differential output capability
• Interface Protocol: SPI and DSP data interface support
• Supply Voltage Requirements: 5V analog supply and 2.7V to 5.25V digital supply range
• Accuracy Specifications: INL/DNL of ±0.1 and ±0.5 LSB respectively
• Settling Performance: 65µs typical settling time
• Package Specification: 124-CSPBGA (15x15) ball grid array format
• Environmental Compliance: MSL 3 rating and equivalent thermal operating range

The AD5535BKBCZ meets all these criteria and qualifies as a direct substitute. The primary distinction is product status: the substitute part is active and available, whereas the original part is obsolete.
