Texas Instruments DAC900U
DAC900U variants from Texas Instruments
DAC900U Overview
What changes between part numbers, and what to check before you lock the BOM — Digital to Analog Converters (DAC).
Key Features
- Footprint / package: SOIC, 28-SOIC (0.295", 7.50mm Width)Land pattern and thermal pad differ between these packages — run a quick footprint check before you swap variants.
- Lifecycle mix: ActiveConfirm lifecycle on the exact MPN, not just the base number prefix.
Target Applications
- Digital to Analog Converters (DAC) — design-in and field replacement
- BOM scrub where only the base prefix is known but suffix is TBD
- Second-source checks when the original MPN is constrained
Ordering Variants
Compare 2 DAC900U part numbers by package, electrical parameters, lifecycle, and availability. Use RFQ for stock and lead-time confirmation.
| Part Number | Description | Package Type | Manufacturer | Lifecycle | RoHS | Availability | Action |
|---|---|---|---|---|---|---|---|
| DAC900U | Package: SOIC | Operating Supply Voltage: 5V | Max Supply Voltage: 5.5V | Min Supply Voltage: 2.7V | Number of Channels: 1 | Number of Outputs: 1 | Number of Bits: 10 | Interface: Parallel | SOIC | Texas Instruments | Active | Compliant | In Stock | |
| DAC900U/1K | Package: 28-SOIC (0.295", 7.50mm Width) | Mounting Type: Surface Mount | Number of Bits: 10 | Operating Temperature: -40°C ~ 85°C | 28-SOIC (0.295", 7.50mm Width) | Texas Instruments | Active | Compliant | In Stock |

How to Choose the Right DAC900U Digital to Analog Converters (DAC)
Match the footprint first
Packages here: SOIC, 28-SOIC (0.295", 7.50mm Width). Open the land-pattern drawing before you substitute a different suffix.
Electrical headroom
Compare voltage and current columns in the variant table. For DAC900U, a suffix with lower voltage or current rating will not survive the same circuit without recalculation.
Temp grade letter matters
Commercial (0–70 °C) and industrial (−40–85 °C+) suffixes look similar in the prefix — confirm ambient + self-heating, not just the first page of the datasheet.
Copy the full MPN
Do not BOM only "DAC900U" — include the full suffix (e.g. 1K). RFQ with reel/tube preference and required date code.
