| Description | DAD1000 is a dedicated ASIC for waveform generation and reset drive in DLP projection systems, matched with DDP1000 and DMD chipsets. |
| Stock Status | In Stock |
| Origin | Original |
Product Overview
DAD1000 is an ASIC developed by Texas Instruments for DLP projection equipment. It integrates signal generator and reset driver to produce timing signals for driving Digital Micromirror Device (DMD). Belonging to TI DLP Discovery 1000/3000 series, it mainly works with 0.7″ XGA DMD chips. This device is now obsolete, suitable for old cinema equipment and engineering projector maintenance projects.
Core Advantages
Integrated DMD Timing Drive Function
Replace discrete components to generate complete control waveforms required by DMD, simplify peripheral circuit layout.
Stable LVTTL Digital Interface
3.3V LVTTL compatible input interface, matched perfectly with DDP1000 controller chipset.
Proven Mature Solution
Mass used in traditional DLP projection equipment, stable performance for legacy equipment repair.
Complete Reset Waveform Control
Built-in internal 5V regulator, supports mirror reset voltage control for normal DMD switching operation.

Frequently Asked Questions
Q1: Is DAD1000 still actively manufactured by TI?
A: DAD1000 is officially obsolete. Our stock is surplus original inventory, only available for equipment maintenance and refurbishment projects.
Q2: Can DAD1000 work independently without DDP1000?
A: No. It must work with DDP1000 controller and matched DMD chip, cannot operate separately.
Q3: What is the recommended alternative for new hardware design?
A: TI DLPA200 or integrated DLP controller solutions are recommended for new projects.
Q4: Can DLPA200 directly replace DAD1000 on existing PCB?
A: Not pin-to-pin compatible. It requires PCB redesign, timing adjustment and firmware modification, not suitable for simple drop-in replacement.
Q5: Why is there no official complete datasheet for DAD1000 on TI website?
A: TI never fully published formal datasheet after discontinuation. All parameters are summarized from historical engineering documents and practical application experience.
Q6: Which DMD model is matched with DAD1000?
A: Mainly matched with 0.7″ XGA DMD within TI DLP Discovery 1000/3000 platform.
Q7: Do you support sample testing of DAD1000?
A: Samples are available. Please send inquiry to confirm stock and sample cost.
Q8: Can you provide real item photos to verify marking?
A: Yes, we can provide actual photos including surface marking before order confirmation.
Q9: What warranty do you offer for DAD1000?
A: 1-year quality warranty for original surplus stock under proper operating conditions.
