ZHCSHK8E october 2017 – july 2023 TAS2770
PRODUCTION DATA
The TAS2770 can operate in two distinct operational modes, each with eight selectable device addresses. In TDM/I2C Mode, audio input and output are provided through the FSYNC, SBCLK, SDIN and SDOUT pins using formats including I2S, Left Justified and TDM. Configuration and status are provided through the SDA and SCL pins using the I2C protocol.
The PDM input can be used for a low latency playback path or as a sensor input.
Table 8-1 below illustrates how to configure the device for TDM/I2C Mode. I2C slave addresses are shown left shifted by one bit with the R/W bit set to 0 (i.e. {ADDR[6:0],1b0}). 5% or better tolerance resistors should be used for setting the mode configuration.
