  • TLV5638-EP: About continuous access

    TI Thinks Resolved
    Part Number: TLV5638-EP Hi, I want to know the timing constraints for continuous access. How long between 1st /CS rising edge and 2nd /CS falling edge is needed? We can not find the time in datasheet. I am looking forward to hearing from you.

  • TLV5638: DAC not showing output for any input signal

    Part Number: TLV5638 I have connected PIC 18F6520 Microcontroller output to DAC DIN, SCLK and CS. All inputs are coming correctly, when analysed on the oscilloscope. I am first giving an output of 0XD002 for programming with internal reference of 2.048V…

  • TLV5638: REF input range vs. VDD supply voltage

    TI Thinks Resolved
    Part Number: TLV5638 Hi team, I would like to see if REF input is 2.5V, VDD should be greater than 4V. But, my customer saw, with VDD=3.3V, TLV5638 can also output 2.5V range. How to understand the relation between REF input range and VDD supply voltage…

  • TLV5638: reference is changed from external to internal from time to time

    Part Number: TLV5638 Customer is reporting this: Specifically, we are talking about the TLV5638. So far, we have installed the component on a good 10k boards. As it looks, it can happen that the reference is changed from external to internal from time…

  • TLV5638: Use SPI which simulated by the McBSP module of f28335 to communicate with TLV5638.

    Resolved
    Part Number: TLV5638 Dear team: One of my customer use SPI which simulated by the McBSP module of f28335 to communicate with TLV5638. Now TLV5638 chip can output DA signal normally, but there is a problem: outa and outb, only one output can be selected…

  • TLV5638-EP: Offset difference between channel A and B of the same device

    Resolved
    Part Number: TLV5638-EP Hello, is the any Information on how much the zero-scale offset differers between channel A and B on the same chip? I have not found that Information in the datasheet. So I would assume the worst case from one output being at the…

  • TLV5638: DAC is not functioning

    TI Thinks Resolved
    Part Number: TLV5638 I am working on DAC tlv5638. I am driving the sclk, cs and data from FPGA to DAC. For FPGA output i have checked it on ILA .Then I have connected the outputs from FPGA to DAC inputs. I have checked the DAC pins of sclk, cs and data…

    TI Thinks Resolved
    Part Number: TLV5638-EP Hi E2E, Good day! May I know the ESD classification/level of TLV5638-EP? Looking forward to your response. Best regards, Franz

  • TLV5638: Part Markings

    TI Thinks Resolved
    Part Number: TLV5638 My company purchased V62/03628-02XE. All parts are correctly marked with "5638ME" as per the datasheets. Under that is "52T". Some parts have "E60N" or "A4YR" on the bottom line. What do these markings mean or what is the difference…

  • TLV5638-EP: Package thermal information/clarification desired

    TI Thinks Resolved
    Part Number: TLV5638-EP In your answer to the question "Need Junction to Case (Theta JC)- TLV5638-EP (V62/03628-02XE)", you gave a list of Theta-JC and Psi-JT for Low and High K boards. However, you gave multiple, different values for each of…
