Stereo Audio SNR ADC Module PCM1802

Description

What is the PCM1802 ADC Module? The PCM1802 is an audio analogue-to-digital converter module offering stereo sound recording with a signal-to-noise ratio (SNR) of 105 dB. It’s designed for high-quality sound applications and can be easily integrated into audio electronics and Arduino projects. Features SNR of 105 dB Audio Analogue-to-Digital Conversion Stereo Sound Recording What is it used for? This module is ideal for multi-track audio recording projects, where microphones can be connected to record on a computer. It’s compatible with Arduino and can be used to develop professional-level audio electronics projects. Tutorial: How to use the PCM1802 Stereo Audio SNR ADC Module Connect the module pins to an Arduino: VCC to 5V, GND to GND, SCK to pin 13, MISO to pin 12, MOSI to pin 11, CS to pin 10. Connect stereo audio pins to IN+ and IN- of the module. Connect a 10kΩ resistor between CS and GND. Load the source code onto Arduino. Check audio quality with an analysis software. Experiment with different audio inputs. Verify technical specifications not mentioned in the datasheet. Adapt the code for your needs. Example Code “`cpp #include void setup() { Wire.begin(); Serial.begin(9600); } void loop() { int16_t left, right; Wire.requestFrom(1024, 4); left = Wire.read() << 8 | Wire.read(); right = Wire.read() << 8 | Wire.read(); Serial.print("Left: "); Serial.println(left); Serial.print("Right: "); Serial.println(right); } “` Mini-project Create a multi-track audio recording system with this module and microphones. Connect the microphones to the module and record onto a computer. Common mistakes Connecting CS to VCC instead of GND. Omitting pull-up resistor. Not verifying technical specifications in the datasheet. Connecting stereo audio to incorrect pins.
