An 8-bit resolution, dual channel A/D conversion chip. It is generally used in circuit applications where the input signal for AD detection is not more than 2 channels. It can be used as an external extension circuit without a built-in AD detection chip to increase the function of AD detection. Working voltage: 5V Resolution: 8-bit (0-5V returns result 0-255) Detection channel: 2 channels Conversion time: 32us Working temperature: 0-70 degrees Celsius Application scenario: The 51 microcontroller circuit detects analog signals, lighting, pressure, gas concentration, weight, etc. Color: Black & Green Material: Metal+Plastic Package Contents: 1*ADC0832 module Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
