Beskrivelse
Description:
PCM1808 Audio Stereo ADC Decoder Amplifier Module is a high-efficiency and economical stereo ADC audio amplifier module with single-ended analog voltage input, which is based on PCM1808 chip. This chip can work in master mode or slave mode and has a double data format with a 24-Bit resolution of Left-Justified. The PCM1808 chip is a stereo A / D converter, which applies a delta-sigma modulator with 64 times oversampling. It has a high pass filter (HPF), which results in removing the input signal component. This chip is equipped with power down and reset utility for pausing the system clock. The PCM1808 is developed for consumer devices that need high performance at low cost, simultaneously. It can be supplied with a 5V DC in analog or 3.3V in digital.
Because of supporting support two I2C interface or three serial port interfaces, so it can easily be interfaced with raspberry and Arduino projects and can support the card reader module. This module is a cheap and high-quality module, so it can be applied in the DIY projects, portable audio player, cellular phone, video camcorder, movie camera, digital camera, PMP/DMB, voice recorder, and so on.
