DAC7760: Automotive device

K.Hamamoto

Part Number: DAC7760
Other Parts Discussed in Thread: DAC8551-Q1, DAC6551-Q1, OPA192-Q1, OPA703

I am looking for the automotive device similar with DAC7760. Our customer need 10~16bit and +/-5V output voltage range DAC.

Do you have any device what can output +/-5V output? And Q1 part.

Hi Koji,

There is not an integrated Vout/Iout device like DAC7760 that is automotive qualified. I would recommend using an automotive qualified voltage output DAC and an op amp to create this +/- 5V bipolar voltage range. I have linked a TI Design below that describes in detail how to design a bipolar voltage output from unipolar DAC output. You could start by looking into DAC8551-Q1 (16-bit) or DAC6551-Q1 (12-bit) as the DAC in this circuit.

Thanks,

Garrett
