- Page 2 Overview The TAS5518-5261K2EVM PurePath Digital™ customer evaluation amplifier module demonstrates the two audio integrated circuits TAS5518 and TAS5261 from Texas Instruments (TI). TAS5518PAG is a high-performance, 32-bit (24-bit input) multichannel PurePath Digital™ pulse width modulator (PWM) based on Equibit™ technology with fully symmetrical AD modulation scheme. It accepts input sample rates from 32 kHz to 192 kHz.

Page 10: Additional Documentation
Related Documentation from Texas Instruments 4.2.2 Overtemperature Protection (OTP) TAS5261 has an on-chip temperature-sensing system. If the chip temperature reaches a critical temperature, the overtemperature warning pin goes low. If the chip temperature continue to increase, the TAS5261 protects itself by shutting down the power stage. In this case, both OTW and SD are low. -
