Texas Instruments TLC Series Digital to Analog Converters – DAC are available at Mouser Electronics. Mouser offers inventory, pricing, & datasheets for . D Easily Interfaced to Microprocessors. D On-Chip Data Latches. D Monotonic Over the Entire A/D Conversion. Range. D Segmented High-Order Bits Ensure. In order to try out the new I/O expansion bus for the MC3 I built a few quick I/O boards. The first one is a simple 8-bit DAC. I had an TLC laying around.

TLC7524CD – D/A converter IC 8 Bit SO-16, TLC7524 – Texas Instruments
You’re the man Kevin! DAC output is first buffered, amplified and then it is connected to a non-inverting summer amplifier with a 10V so the final output voltage is V.
Send to a friend.
This keeps both switches inside of the DAC biased at the same potential, even though there is still the limitation of having VDD be larger than the Bias voltage.
This figure from the datasheet shows the resistor ladder at top and the digital switches beneath. Oct 17, 6: We are glad that we were able to resolve this issue, and will now proceed to close this thread. Update A DAC can be quite useful as a debugging tool when connected to a scope.
Can I return the calibrated item if I am not satisfied with the device itself? How to quickly remove all unused packages under Debian.
For absolute accuracy, the circuit would need a few slight changes, which could be as simple as a very accurate 5V supply and high-precision resistors. No license, either express or implied, by estoppel or otherwise, is granted by TI.
The Neato XV vacuum cleaner.
What do I receive if I choose a calibrated product at Distrelec? With all ‘1’ on the data latches the output voltage on Vref was a little less then 2. Last but not least both specs call the resistance between Vref 15 to ground tlcc7524 be 5k to 20K.
TLC Datasheet(PDF) – Texas Instruments
I have tried putting a voltage follower after the DAC and a 1M resistor to get the voltage out but nothing helps. Linux Upgrading Debian Wheezy to Jessie.
Jaakko Nevala I have ltc7524 several of these available and time is of the essence. In trying to use multiple sources for this DAC, I came across the differences in trying to use them in “voltage mode”. Jaakko Nevala Device still identifies 3.

Unfortunately Texas Instruments cannot guarantee the performance of the DAC if the datasheet specifications are not met. Leo, I salvaged your mail from the filter. Enclosure for the MC3. Oct 20, 7: A quite tidy backside.
The level was then about right but as soon as I began loading the output the level also dropped significantly.
The newly created question will be automatically linked to this question. Because I need 5 volt output I bypassed the tlc524 by replacing the voltage follower with a non-inverting x2 opamp but I remain curious. Transceiver build – part 2. Expert technical support on hand Our expert team have over 25 years experience solving problems and providing expert tllc7524. How ever I would like your opinion of my design if I may. As the product is customised to your requirements, we cannot accept returns should you decide you no longer want the instrument.
I believe that the formula in the TLC datasheet is theoretically correct.
I have already several of these available and time is of the essence. In the application examples the REF pin is an input and the OUT1 and OUT2 are outputs feeding a differential amplifier but from this vague description I figured it might be possible to make tlx7524 work the other way around with the REF pin acting as a single output.
The first one is a simple 8-bit DAC.

Image is for illustrative purposes only. Replacing a failed disk in an MD array. All orders for calibrated items are non-cancellable and non-returnable. For glc7524 case this is perfectly adequate and the linearity is good. I did some more testing and got interesting results.
