Other Parts Discussed in Thread: ADS131M08
Hi team，
The attachment is the schematic diagram of the customer's ADS131M08. Please help to check, the chip part, the customer's library is not completed, and a 32PIN is used instead.
A few other questions to ask:
1 At present, our precision requirements are not very high. The input signal does not require amplification. Therefore, can the two resistors and one capacitor at the ADC sampling input end be canceled directly. As shown in the figure R2 R3 C2.
2 The recommended external reference voltage is 1.25V, can it be directly connected to 3.3V?
3 Can the input crystal oscillator use other frequencies? As long as it does not exceed 8.192MHZ? How much error can SPI_CLK and CLK_IN accept?
