PRODUCTION DATA
The DACx3401-Q1 implement a device lock feature that prevents an accidental or unintended write to the DAC registers. The device locks all the registers when the DEVICE_LOCK bit (address D1h) is set to 1. To bypass the DEVICE_LOCK setting, write 0101 to the DEVICE_UNLOCK_CODE bits (address D3h).
