JAJSFF9B March 2016 – May 2018 TAS5751M
PRODUCTION DATA.
The TAS5751M PWM processor contains an internal oscillator to support autodetect of I2S clock rates. This reduces system cost because an external reference is not required. A reference resistor must be connected between pin 16 and 17, as shown in Table 18.
Writing 0x00 to register 0x1B enables the trim that was programmed at the factory.
Note that trim must always be run following reset of the device.
