Product Code : SCL-EELE-12711
Indian Lab Suppliers supplies the 8-bit Multiplying Digital to Analog (D to A) Converter (based on AD1408) Trainer (Product ID: 12711) as part of its electronics engineering lab equipment range. It demonstrates an 8-bit multiplying D/A converter whose output is the product of the digital input and a reference.
Quick Answer
Eight SPDT switches set the digital input, shown on LEDs, and the AD1408 converter produces an output current proportional to that code multiplied by the reference current. A 741 op-amp turns the current into a voltage, and a 723 regulator provides a stable reference, so students can plot output against input code and then vary the reference to see the multiplying action. Supplies of ±15 V and 5 V (50 mA each) are built in, and the board runs from 230 V ±10%, 50 Hz mains with fuse and jewel light. Operating instructions with theory, design procedure and report suggestions are supplied.

Frequently Asked Questions
What does multiplying mean for this DAC?
The output equals the digital input fraction multiplied by the reference, so changing the reference scales the output.
Why is a 741 op-amp used?
To convert the DAC output current into a voltage.
How is the digital input set?
With eight SPDT switches, shown on LEDs.
