DRV2604: Question of DRV2604's Analog Input

Wayne Chen (Audio AE)

Part Number: DRV2604

Hi SIrs,

We would like to know if there is any bit address can be revised for the vibrator be shaking or quiet alternatively in analog input mode. The vibrator is always shaking when customer put the a long period analog signal into the pin B1.

Example:

Analog input Amplitude>0.9V, DRV2604 shakes the vibrator

Analog input Amplitude<, =0.9V, DRV2604 stops shaking the vibrator

Thank you and Best regards,

Hi Wayne,

I do not fully understand the question. Is this using an analog input for a LRA or ERM? The analog input uses a 1.8V reference. So when inputting 1.8V, the output should be full scale. At 0.9V, hte output should be 50% and at 0V the output should stop.
