Frequently Asked Questions

What special features are available when using an L3 microcontroller with the UDA1345TS?

It supports digital volume control, soft mute via cosine roll-off (in 1024 samples), and digital de-emphasis for 32, 44.1, and 48 kHz.

What data formats does the UDA1345TS support over I²S-bus?

It supports combined MSB justified data output up to 24 bits, as well as LSB justified inputs of 16, 18, and 20 bits.

What is the maximum analog input voltage supported by the ADC?

The input voltage can be up to 2 V (RMS) when the current through the ADC input pin is limited to approximately 1 mA.

How much power does the UDA1345TS consume in its lowest power state?

The power consumption in power-down mode (PD mode) is very low, specified at 2.0 mW.
