  • DAC60508: Unable to readback DAC60508 ChipID and also can't get DAC channel output

    Part Number: DAC60508 Hi, my read timing sequence is following: HAL_GPIO_WritePin(GPIOC, SS7_Pin, GPIO_PIN_RESET); spiWriteRegData(0x81,0x00,0x00); HAL_GPIO_WritePin(GPIOC, SS7_Pin, GPIO_PIN_SET); delay_ms(1); HAL_GPIO_WritePin(GPIOC, SS7_Pin, GPIO_PIN_RESET…

  • DAC60508: DC output impedance affects Vout accuracy?

    Resolved
    Part Number: DAC60508 Hello, Datasheet specify DC output impedance, 0.085ohms(typ) with midscale output and 15ohms(typ) with DAC output at GND or Vdd. Vout drops as follows due to the DC output impedance? Vout = Vout target * load /( DC output impedance…

  • DAC60508: no CS_ toggling is required at synchronous mode?

    Resolved
    Part Number: DAC60508 Hello, My customer uses one DAC60508 and a host communicates only the DAC60508 via SPI. So the SPI interface is not shared with other device. And they do not use asynchronous update, only use synchronous mode. In this case, can…

  • RE: DAC80508: Inquire about sample rate calculation.

    Resolved
    Hi Lee, This is not exactly the case. Lee SungYun said: DAC80508 (16-bit) is 1/5 us = 200 kSPS, DAC70508 (14-bit) is 1/5 us * 4 = 800 kSPS, DAC60508 (12-bit) is 1/5 us * 8 = 1600 kSPS = 1.6 MSPS. Settling time is a spec of the output buffer that consists of…

  • DAC60508: Confusing VREF

    TI Thinks Resolved
    Part Number: DAC60508 I'd like to drive the DAC60508 outputs to the VCC rail of 3.3V+/-5%. Can I connect VREF to VCC with DIV=2 and GAIN=2 without getting a reference alarm condition that shuts down the DAC outputs. I see you have divided the Vrefin…

  • DAC60508: DAC programming problem

    Resolved
    Part Number: DAC60508 Hi Uttam, By the datasheet to get Gain = 2 (Max out voltage 2*Vref, need to set BUFF-GAIN = 1, REF-DIV = 0. I did it, but the device output is 2.5V instead of expected 5V by this setting. Why?
