  • LM48580: Detect output voltage when IC is enabled by SHDN pin without PWM at IN+ pin

    Part Number: LM48580 Hi TI, I have a problem when the LM48580 is enabled by the SHDN Pin, but no input over IN+ is done. We are using a Timer of a µC with a PWM which is output to IN+. When no PWM is played and the IC is "ON" than at OUT+ and OUT- I…

  • LM48580: Question of the LM48580's Common Mode Input Voltage Specification

    Resolved
    Part Number: LM48580 Hi Sirs, The Vin (max) of the LM48580 is 3Vpp (~1.060Vrms) according to the datasheet page 5. In case of 5V VDD, will it damage the LM48580 device or just generate output clipping when the input voltage exceeds 3Vpp since the absolute…
