1.CS1237 Product Details： With external voltage regulator, use TL431 chip external voltage (2.5V) as the excitation source of external pressure sensor, voltage is more stable. Chip function description: CS1237 is a high precision, low power consumption ADC chip, one differential input channel, built-in temperature sensor and High precision oscillator. The PGA of the CS1237 can be 1, 2, 64, or 128.  The default value is 128. CS1237 ADC data output rate in normal mode can be 10Hz, 40Hz, 640Hz, or 1.28kHz by default Is 10Hz; MCU can communicate with CS1237 through 2-wire SPI interface SCLK and DRDY/DOUT to advance it Row configuration, such as channel selection, PGA selection, and output rate selection.

Main functions and features of the chip: Built-in crystal oscillator Integrated temperature sensor With the Power down function 2-wire SPI interface, the maximum speed is 1.1MHz
