How Does It Compare with Other JLab Converter Trainers?
| Trainer | Converter type | Power supplies | Meter, switches and indicator |
|---|---|---|---|
| This trainer (EL-DEECP-1196) | D/A, R-2R ladder | 5 V DC, 150 mA; 15 V DC, 150 mA | 1 voltmeter; SPDT switching (listed as 1); one output indicator |
| Digital to Analog D and A Converter using Weighted Resistor Network | D/A, weighted resistor network | 5 V DC, 150 mA; +15 V DC, 150 mA | 1 voltmeter; 4 SPDT switches; one output indicator |
| Analog to Digital A and D Converter | A/D and D/A, R-2R and successive approximation | 5 V DC, 100 mA; 0–10 V DC, 200 mA; +15 V DC, 250 mA | 1 voltmeter; 4 SPDT switches; one output indicator |
Choose this trainer to teach the R-2R ladder on its own. The weighted resistor trainer shows the simpler but less practical network for comparison, and the A to D converter trainer adds analog-to-digital conversion by successive approximation.
What Is the R-2R DAC Trainer Used For?
A DAC turns a binary number into a proportional voltage, the step that lets digital systems drive loudspeakers, motors and other analogue loads. The R-2R ladder does this with just two resistor values, R and 2R, repeated for every bit. Each bit switch connects its leg of the ladder to the logic 1 or logic 0 level, and the ladder weights the bits so that the most significant bit contributes half of full-scale output and each lower bit half as much as the one above it. Because only two values are needed, the resistors are easy to match, and more bits can be added by extending the ladder.
Students set binary codes with the switches, read the analogue output on the voltmeter, and plot output voltage against the binary value to check that the steps are equal and the graph is a straight line; any uneven step points to a mismatched resistor. The experiment belongs to the data-conversion unit of B.Sc. electronics and physics, engineering diplomas and ITI electronics trades, and pairs naturally with the weighted resistor DAC to show why the ladder is preferred.
What to Specify When Ordering
- Number of input switches and bits — the listing reads “1 SPDT switches”; confirm the bit count your practical manual needs.
- Mains input — give your supply voltage.
- Patch cords — not mentioned in this listing; add them to the enquiry if needed.
- Quantity — the minimum order is 10 units.
Frequently Asked Questions
Why use an R-2R ladder instead of a weighted resistor network?
A weighted resistor DAC needs a resistor value that doubles for every lower bit, and such a wide spread of values is hard to make accurate. The R-2R ladder uses only two values, so it is easier to match and to extend.
What power supplies does the trainer have?
Two DC regulated supplies: 5 V DC at 150 mA and 15 V DC at 150 mA.
How many input switches does it have?
The listing says “1 SPDT switches” for selecting logic 1 and 0, which may be a typing slip, as a multi-bit DAC normally needs one switch per bit. Confirm the number and the bit count with JLab before ordering.
How does it differ from the A to D converter trainer?
This trainer studies digital-to-analog conversion with the R-2R ladder only. The A to D converter trainer covers both directions of conversion, including successive approximation, and has a 0–10 V DC supply.
Who manufactures this DAC trainer?
JLab, the trading name of Jain Laboratory Instruments Pvt Ltd, at its works in Ambala, Haryana, India.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a manufacturer of electronics trainers and laboratory equipment in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The R-2R DAC trainer is produced at JLab’s own works rather than bought in from a trader, so institutes, dealers and importers buy factory-direct, every unit is visually inspected before dispatch, and repeat orders are handled by the manufacturer. It is registered for GST under GSTIN 06AADCJ9848D1ZE and identified by Legal Entity Identifier 549300DTGS77DGYD6N03. JLab exports worldwide and ships to buyers in every region — for example Ghana in West Africa, Fiji in Oceania, Tajikistan in Central Asia, Algeria in North Africa and the USA in North America.
