Product description
This module adopts 24-bit high-precision A/D converter chip hx711, which is designed for high-precision electronic scales with two analog channel inputs and an internal integrated 128 times gain programmable amplifier. The input circuit can be configured to provide bridge voltage bridge type (such as pressure, weighing) sensor mode, is an ideal high-precision, low-cost sampling front-end module;
Specifications: 1. Two selectable differential input channels
2. On-chip source low noise PGA with selectable gains of 32, 64 and 128
3. On-chip power regulator for load cell and ADC analog power supply
4. On-chip oscillator, no external components required, external crystal optional
5. On-chip power reset
6. Simple digital control and serial interface: pin-driven control, no programming required
7. Selectable 10SPS or 80SPS output data rate
8. Synchronous 50 and 60Hz power supply rejection
9. Current consumption including on-chip analog power regulator: < 1.5mA for normal operation, < 1uA for power down
10. Operating supply voltage range: 2.6 ~ 5.5V
11. Operating temperature range: -20 degrees ~ +85 degrees Celsius
