Arrives
- HX711 is a specially designed for high precision electronic scales for 24-bit A/D converter chip.
- Operating Voltage Range: 2.6~5.5V;Operating Current: <1.7mA, Shutdown Current: <1μA; Operating Temperature Range: -20°C to +85°C
- The chip with the rear end of MCU chip interfaces and programming is very simple, all control signals from the pin driver without internal chip register.
- Input selector switch can select any channel A or channel B and its low noise, programmable internal amplifier is connected. A programmable channel amplifier of 128 or 64, corresponding to the full amount of differential input signal amplitude was ± 20mV or ±40mV. Channel B, compared to a fixed gain of 32 for the parameter recognition system.
- Compared with the same type of other chips that integrates the peripheral circuits including power supply, on-chip clock oscillator with other types of chips, high integration, fast response, strong anti-interference advantages. Reduces the total cost of electronic scale, improves overall performance and reliability.
- Free 30-Day Returns
- Full Refund for Damaged or Incorrect Items
- Guaranteed Delivery or Money Back
- Secure Checkout & Fast Support

1. Power consumption (including power supply circuit): more typical.
2.Operating Current: <1.7mA, Shutdown Current: <1μA
3.Operating voltage range: 2.6~5.5V
4.Operating temperature range: -20°C to +85°C.
5. Automatic power on reset circuit.
6. Two selectable differential inputs.
7. Rene-chip programmable quiet amplifier, selectable amplifier of 64 and 128.
Rene-chip voltage regulator delivers power directly to the external sensor and on-chip A/D converter.
Rene-chip clock oscillator does not require external components, if necessary Can also be used as an external crystal or watch.
10. Easy digital control and serial communication: all are controlled by input pins, the chip registers without programming.
11. Choose 10 Hz or 80 Hz output data rates.
12. Simultaneous rejection of 50 Hz and 60 Hz current interference.
Package includes:
3 x HX711 A/D converter chip converter.
3 x pin header
