PCM3794ARHBT Overview
For space-saving purposes, it is packaged in 32-VFQFN Exposed Pad. Tape & Reel (TR) packaging is adopted. It can perform highly efficiently in various applications since it is a type of Stereo Audio. As far as mounting types are concerned, it uses Surface Mount. Using -40°C~85°C as the operating performance allows it to operate normally. 2 / 2 ADC / DAC is integrated into it. An analog circuit is supplied with a voltage of 2.4V~3.6V. 1.71V~3.6V is the supply voltage for the digital circuit. In order to avoid reflections off the end of the transmission line, 32 terminations are used. In electronic terms, it is a kind of 32-pin device. With 32 pins, it is configured. More related parts can be found by using its base part number PCM3794. Voltage should not exceed 3.6V. It is recommended to maintain a voltage of 1.71V as the minimum value. It operates on a supply voltage of 3.3V. The device can operate with a voltage of 3.3V. Digital signals are converted into analog signals using 2 D/A converters. During any given time, a circuit should carry a current of 10μA.
