Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DAC8562FSZ-REEL are identified based on the following allowed electrical and mechanical parameters:

• 12-bit resolution (Number of Bits)
• Single D/A converter channel (Number of D/A Converters)
• Voltage output configuration (Output Type)
• R-2R or String DAC architecture
• Operating temperature range compatibility
• Surface mount packaging
• ROHS3 compliance and Active product status

The identified substitutes maintain the core 12-bit, single-channel DAC functionality while permitting variations in settling time, reference configuration, supply voltage ranges, package form factor, and INL/DNL specifications within acceptable engineering tolerances for data acquisition applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain Active product status and ROHS3 compliance, qualifying them for current production use. Selection between the DAC8562FSZ-REEL and its substitutes depends on specific application requirements:

The DAC8562FSZ-REEL provides a fixed 5V supply requirement with internal reference and buffered output in a 20-SOIC package. This configuration is appropriate for applications with dedicated 5V power rails and standard PCB real estate allocation.

The AD5512AACPZ-REEL7 offers superior settling time (1µs versus 16µs) and tighter INL/DNL specifications (±0.5 LSB) with flexible supply voltage ranges (2.7V ~ 5.5V). The 16-LFCSP package provides a smaller footprint but requires external reference configuration and unbuffered output handling.

The AD5681RBRMZ combines flexible supply voltage ranges with dual reference capability (external or internal) and buffered output in a compact 10-MSOP package. The String DAC architecture and extended operating temperature range (-40°C ~ 105°C) support broader application scenarios, though INL/DNL specifications are ±1 LSB maximum.

Frequently Asked Questions (FAQ)

Q: Can AD5512AACPZ-REEL7 directly replace DAC8562FSZ-REEL in existing designs?

A: Direct replacement requires circuit redesign. The AD5512AACPZ-REEL7 uses unbuffered output and requires external reference, whereas the DAC8562FSZ-REEL provides buffered output with internal reference. Package footprints differ (16-LFCSP versus 20-SOIC), necessitating PCB layout changes.

Q: What are the key differences between internal and external reference configurations?

A: The DAC8562FSZ-REEL includes an integrated reference, simplifying circuit design and reducing component count. The AD5512AACPZ-REEL7 requires an external reference source, providing design flexibility but increasing circuit complexity. The AD5681RBRMZ supports both configurations, allowing selection based on application requirements.

Q: How do settling time differences affect application performance?

A: Settling time determines the speed at which the DAC output reaches final value after a digital input change. The AD5512AACPZ-REEL7 (1µs) is suitable for high-speed applications. The DAC8562FSZ-REEL (16µs) and AD5681RBRMZ (7µs) are appropriate for moderate-speed data acquisition. Application timing requirements must be verified against these specifications.

Q: Are package size differences critical for substitution?

A: Package selection depends on PCB layout constraints and manufacturing capabilities. The 20-SOIC (DAC8562FSZ-REEL) provides standard pitch spacing. The 16-LFCSP (AD5512AACPZ-REEL7) and 10-MSOP (AD5681RBRMZ) offer reduced footprints for space-constrained designs. Existing PCB designs require layout modification for different packages.

Q: What supply voltage flexibility do substitutes provide?

A: The DAC8562FSZ-REEL requires fixed 5V supplies. Both AD5512AACPZ-REEL7 and AD5681RBRMZ operate across 2.7V ~ 5.5V ranges, enabling use in multi-voltage systems and low-power applications. Digital supply for AD5681RBRMZ extends to 1.8V, supporting modern low-voltage digital logic interfaces.

Q: How do INL/DNL specifications impact measurement accuracy?

A: INL (Integral Non-Linearity) and DNL (Differential Non-Linearity) define conversion accuracy. Tighter specifications indicate better linearity. AD5512AACPZ-REEL7 (±0.5 LSB) provides superior accuracy compared to DAC8562FSZ-REEL (±0.75 LSB) and AD5681RBRMZ (±1 LSB maximum). Application accuracy requirements determine acceptable specification ranges.
