Part Number: TAS2770

Dear Concern,

In TAS2770, there is pull down Resistance for Digital IO pin i.e. 18K mentioned in datasheet.

IRQZ and SDZ pins are the active open drain, then how to pull down to GND.

please find the Below image for clarification.

Kind Regards,

Hi, Shubham,

IRQZ and SDZ pull-up or pull-down resistors are not required. IRQZ has an optional internal 20k pull-up resistor to IOVDD and the user can disable it in case he prefers an external pull-up resistor.
