ADS1256 24 비트 8채널 ADC 변환 모듈
(ADS1256 24 Bit 8 Channel ADC Module)
개요
- 본 제품은 멀티플렉서를 내장한 TI 사의 ADS1256 24비트 ADC 칩을 탑재한 모듈입니다.
- 8개의 채널을 ADC할 수 있으며, SPI인터페이스를 통해서 마이크로컨트롤러와 인터페이스 할 수 있습니다.
특징
- 1. A0-A7 ADC 8 input channels, can be easily configured as a differential input and a single-ended input.
2. Low-noise wafer temperature drift Vishay metal film resistors.
3. The input filter capacitor (104), one for each channel.
The high-speed low-noise LDO, high power supply rejection ratio, low quiescent current.
5. The digital signal frequency attenuation resistor, external high frequency noise isolation.
6. ADR03 2.5V voltage reference, by OPA350 cache consisting of 0.1Hz ~ 10Hz low-pass filter circuit, high-capacity tantalum and ceramic capacitors in parallel and with low noise metal film resistors wafer effectively suppress low-frequency noise.
7. 100uF bulk filter tantalum capacitors, and inductors LC filter circuit, the power is more pure.
8. Analog signal and digital signal wiring separated.
9. To increase the GND, 2.5V, 3.3V test point, make it easier to debug circuit.
