DAC8802IPWR Equivalent & Substitute Parts

Part Overview

The DAC8802IPWR is a 14-bit digital-to-analog converter manufactured by Texas Instruments, designed for data acquisition applications requiring dual D/A conversion channels with current output. The device operates across a wide supply voltage range of 2.7V to 5.5V for both analog and digital supplies, making it suitable for mixed-signal systems. With an active product status and ROHS3 compliance, the DAC8802IPWR remains in production with 1439 units currently in stock. Substitute parts are identified when the original part becomes unavailable, when supply chain constraints occur, or when design flexibility permits component alternatives that maintain functional and electrical equivalence.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DAC8802IPWR is determined by strict alignment of the following critical parameters:

• Resolution: 14-bit conversion capability
• Channel Count: Dual D/A converters (2 channels)
• Output Configuration: Current output, unbuffered topology
• Interface Protocol: SPI digital communication
• Reference Architecture: External reference input
• Settling Performance: 500ns typical settling time
• Linearity Specifications: INL/DNL ±1 LSB maximum
• Operating Temperature Range: -40°C to 85°C
• Package Format: 16-TSSOP surface mount
• Supply Voltage Compatibility: Operation within 2.7V to 5.5V range

The AD5555CRUZ from Analog Devices Inc. meets all mandatory substitution criteria across these parameters, enabling direct functional replacement in applications where the DAC8802IPWR is specified.

Parameter Comparison

Engineering Selection Recommendations

Both the DAC8802IPWR and AD5555CRUZ maintain active product status with full ROHS3 compliance and REACH unaffected certification. The DAC8802IPWR supports a wider analog supply voltage range (2.7V to 5.5V) compared to the AD5555CRUZ (5V fixed), which may be a determining factor in applications requiring flexible supply configurations. The AD5555CRUZ features improved moisture sensitivity classification (MSL 1, Unlimited shelf life) versus the DAC8802IPWR (MSL 2, 1 Year), providing extended storage capability. Both devices are manufactured to identical electrical specifications for resolution, settling time, and linearity performance. Selection between these parts should be based on specific supply voltage requirements and storage/shelf-life constraints of the application.

Frequently Asked Questions (FAQ)

Q: Can the AD5555CRUZ directly replace the DAC8802IPWR in existing designs?

A: Yes, the AD5555CRUZ provides functional equivalence across all critical electrical parameters including 14-bit resolution, dual-channel configuration, 500ns settling time, SPI interface, and identical linearity specifications. Both devices use the same 16-TSSOP package format and surface mount technology, enabling direct PCB substitution without layout modifications.

Q: What is the primary difference between these two parts?

A: The DAC8802IPWR supports analog and digital supply voltages from 2.7V to 5.5V, while the AD5555CRUZ operates at a fixed 5V supply. Additionally, the AD5555CRUZ offers superior moisture sensitivity rating (MSL 1 with unlimited shelf life) compared to the DAC8802IPWR (MSL 2 with 1-year shelf life).

Q: Are there any architectural differences between the DAC8802IPWR and AD5555CRUZ?

A: The DAC8802IPWR uses a multiplying DAC architecture, while the AD5555CRUZ employs an R-2R architecture. Both architectures deliver identical electrical performance specifications for this application category, with no functional impact on substitution compatibility.

Q: Do both parts require external reference circuitry?

A: Yes, both the DAC8802IPWR and AD5555CRUZ require external reference inputs. The external reference architecture is identical between both devices, allowing existing reference circuits to function without modification.

Q: What packaging considerations apply to substitution?

A: Both parts are supplied in 16-TSSOP surface mount packages with identical 0.173-inch (4.40mm) width specifications. No PCB layout changes or reflow profile adjustments are required for substitution.
