S-bus input as digital source.
Although a level of 1.414 V (RMS) would be required to optimal drive the ADC in this gain setting, this level can not
be used. Due to the 3.3 V supply voltage input, signals of 1.17 V (RMS) and higher will result in clipping.
APPLICATION INFORMATION
The UDA1335H can only be used in combination with an external (E)PROM. This (E)PROM can be connected to the
port pins (P0 and P2) of the UDA1335H and must contain the firmware for the microcontroller. The UDA1335H will be
delivered with standard USB compliant firmware. The I
2
C-bus EEPROM is optional and can be used to configure client
specific configurations and descriptors.
More information about the firmware, descriptors and configurations can be obtained from several application notes.
