CS1237 24-bit ADC Module Onboard TL431 External Reference Chip Single-channel

CS1237 24-bit ADC Module Onboard TL431 External Reference Chip Single-channel

• 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 defaultIs 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.
• Built-in crystal oscillator
• Integrated temperature sensor
• 1 24-bit differential input without loss of code, ENOB is 20 bits (5V) 19.5 bits (3.3V) when PGA=128
• 2-wire SPI interface, the maximum speed is 1.1MHz
