1 Chip Function Description
The CS1237 is a high-precision, low-power analog-to-digital conversion chip with one differential input channel, built-in temperature sensor and high-precision oscillator.
The CS1237 PGA is optional: 1, 2, 64, 128. The default is 128. CS1237 ADC data output rate in normal mode is optional: 10Hz, 40Hz, 640Hz, 1.28kHz, default is 10Hz; The MCU can municate with the CS1237 through the 2-wire SPI interface SCLK, DRDY /DOUT to configure it, such as channel selection, PGA selection, output rate selection, and so on.
