HX711 is a precision 24-bit analog digital converter (ADC) designed for weigh scales and industrial control applications to interface directly with a bridge sensor. It is possible to use both outputs of the integrated circuit.
Where to buy?
• Two selectable differential input channels (To use channel B, R7(100R), R8(100R) and C8(100nF) must be populated.)
• Current consumption including on-chip analog power supply regulator: normal operation < 1.5mA, power down < 1uA
• Operation supply voltage range: 2.7 ~ 5.5V
