CS1238 24-Bit 2 Channel ADC Module with TL431 Chip
CS1237 is a high-precision, low-power ADC chip, a differential input channel, on-board temperature sensor and It is a high precision oscillator. PGA of CS1238 is optional: 1, 2, 64, 128 and the default value is 128. ADC data output rate of CS1238 is optional: 10Hz, 40Hz, 640Hz, 1.28kHz and default value is 10Hz.
MCU with CS1238 via 2-wire SPI interface SCLK and DRDY/DOUT to advance rpw configuration such as channel selection, PGA selection, output speed selection can communicate.
With an external voltage regulator, the TL431 chip external voltage (2.5V) is used as the excitation source of the external pressure sensor, and the voltage is more stable.
