  • Forum Post: Re: Cheap single or dual channel precision DAC

    Anjana Govil
    In case the primary concern of the customer is price (for a single or dual DAC), the best family to consider is the famly of SC-70 DACs. It is a family of 8/10/12/14/16 bit DACs all available in the SC-70 package whose pricing starts at $0.55/1ku. The 12 bit version in this case will be DAC7311. Besides...

    Drew Lundsten
    Hi, Reading the TLV5610IYZ or IDW/IPW datasheets, I can't tell whether DOUT will power-on default to high-Z, or if it is always driven but just not latching the DIN shift register until it's enabled. I would (like to) assume that DOUT is high-z until you set CTRL0 bit 3 to 1, but this kind...

    Markus Luecke
    Hello everybody, I try to use the DAC7562. At the moment I can write over SPI to output something on channel A or channel A and B tohether. But in the case I want to output something on channel B it doesn't work. If I write the command 0x19**** oder 0x11**** (**** are the output value for the...

    I'm using ADS1015 in one of my development.I have configured for 2.048 volt reference with single ended analog input. As per design we are dropping the 4-20mA current from a pressure transmitter across a 220 ohm resistor. I have given this current in column E in the following table. A ctual voltage...

  • Forum Post: Re: Multiple DAC7513s on same SPI bus

    John Schnellenberger
    Tony, Thanks for your detailed response. We are planning on using two of these DACs as well as a third IC on the SPI bus. Based on your explanation, I'm assuming that the loading effects will not be significant enough to cause any communication problems. Is that correct? Thanks. John S.

    Hi. I have some problems with the DAC7562. The SPI communication is OK. I can see the frames on the oscilloscope. But I get no output signal and no internal reference on the depending pin. In which order must the config frames send? I couldn't find any documentation for this. Thanks...

    Michael Lindemann
    I have a DAC1220 EVM wired up and was hoping to command some nice voltages, but unfortunately, such is not the case for me. As soon as I power up the board I get a 2.5-2.6 volt output which ripples some when I connect my powered-up microprocessor. My settings are: S1 (sys ref): internal (to the right...

  • Forum Post: AMC7812 Internal DAC resistance

    Carlos Luis Bernal Quintero
    I'm using the AMC7812's DACs to margin some Voltage regulators. I have a series resitor connected between the AMC DAC output and the VR's feedback. While the DAC is not configured the internal resistor ~10K affects my feedback voltage. How do you recomend to use the AMC to margin VRs?

    Gary Richardson
    I have a board with a DAC7512 on it; VDD is 3.3 volts (measured 3.2). SYNC, SCL & DIN are driven by a SN74AHC541. The dac output is stuck at 2.4 volts. SYNC and DIN toggle between 3.2 volts and ground. SCL switches from 3.2 to 2.4 volts when SYNC switches to ground and toggles between 2.4 and ground...

    Hi, I'm creating software for DAC7578 QFN-24 package. But am not getting expected analog output in the ouput pin. I am providing vref 3.3v and the circuit is made according to the datasheet. When I write 0x80 it is showing 0.125v output instead of 0.103v, likewise 0x0F0 showing 0.238v instead of...

    Can anybody recommend a 12 bit DAC, easy to use, with some code examples or evaluation board with software, like DAC7614, TLV5614 or similar. I need to generate 4 analog output voltages using an MSP430 (SPI or I2C) to control each channel.
