Thread Summary
Thread Summary
The user asked if both the ON Semi NSS1C300ET4G and STMicroelectronics STD2805T4 are recommended for use with ADAU145x and ADAU146x DSPs. The final answer confirms both are recommended, with the NSS1C300 being automotive qualified and the STD2805 being cheaper. The accompanying answer notes that both parts are out of stock as of August 2026, and suggests looking for similar transistors with the same parameters for SigmaDSP DVDD regulation.AI Generated Content

Tomoto,
Both of these PNP transistors have been tested with the ADAU145x and ADAU146x DSPs. Both are recommended. The STD2805 is considerably cheaper, but the NSS1C300 is automotive qualified, while the STD2805 is not,
