HX710(A/B) is a precision 24-bitanalog-to-digital converter (ADC) with built-intemperature sensor (HX710A) or DVDD, AVDD voltage difference detection (HX710B). It’s designed for weigh scales and industrial control applications to interface directly with a bridge sensor.
The input low-noise amplifier (PGA) has afixed gain of 128, corresponding to a full-scale differential input voltage of ±20mV, when a 5V reference voltage is connected to the VREF pin. On chip oscillator provides the system clock without any external component. On-chip poweron-reset circuitry simplifies digital interface initialization. There is no programming needed for the internal registers. All controls to the HX710 are through the pins.
Key Features
-
- 24-Bit Resolution: Provides highly detailed digital readings.
- Integrated Design: Features an on-chip oscillator, eliminating the need for external components.
- Fixed Gain: Includes a low-noise programmable gain amplifier (PGA) with a fixed gain of 128.
- Data Rate: Selectable output data rate of 10 or 40 samples per second (SPS).
- Voltage Detection: Designed for 2.6V–5.5V operation, with specific capability to measure voltage differences between DVDD and AVDD.
- Interface: Simple 2-wire serial interface (clock and data), similar to the HX711, making it easy to use with Arduino or other microcontrollers. [1, 2, 3, 4, 5]
Common Applications
-
- Air Pressure Sensor Modules: Specifically, the 0-40kPa modules (often used in DIY kits) that allow for 2.5mm tube connections.
- Liquid Water Level Detection: By measuring pneumatic pressure.
- Weighing Scales: Similar to HX711, it can be used with load cells.
- Altitude/Weather Monitoring: Used in altimeters and barometers. [1, 2, 3, 4, 5]
