CS8406-CSZ Overview
Additionally, there is a case included with the book as well. The mounting type recommended by the manufacturer is Surface Mount. A 28-SOIC (0.295, 7.50mm Width) case contains it. A 2 channel is present on the device. For your reference, this part contains Audio Transmitter functions. Digital Audio Interfacing can be used with the device. We supply it within 3.3V~5V. Using -10°C~70°C TA as a temperature range, this device operates. A search for parts belonging to the CS8406 family will yield similar results. Refer to the device's specifications: 8kHz ~ 192kHz. An accessible 28 pin can be found on the chip. You can use CONSUMER CIRCUIT to sort consumer ICs on a part. The chip conducts in a 5V-voltage supply. Using 12.7mA as the supply current, it operates.
