Avia Semiconductor analog-to-digital transducers for electronic scales

The HX711 is a precision 24-bit transducer for direct communication with the bridge sensor. It has two input channels and a programmable amplifier with 32, 64 or 128 gain. Data is transmitted at 10 or 80 SPS, depending on the setting. The supply voltage is in the range of 2. 6. . . 5. 5 V and the permissible operating temperature is from -40°C to +85°C. The system is available in the SOP-16 housing.

The HX710 series of transducers has a resolution of 24 bits. The HX710A includes a built-in temperature sensor, the HX710B differential voltage sensor for the analog and digital parts, and the HX710C strain gauge power switch to help save energy. The built-in low-noise amplifier has a constant gain of 128 and is compatible with a differential input of ±20 mV. The oscillator included in the circuits allows operation without the need to provide an external clock signal. Data is transmitted via a two-wire serial bus at 10 or 40 SPS, depending on the setting. The system does not require programming of registers for operation. The systems are delivered in SOP-8 enclosures.

The HX712 is a 24-bit transmitter for electronic scales and industrial control applications. It has one input channel as well as a programmable amplifier with 128 or 256 gain. The system also includes a strain gauge beam power switch and a battery voltage sensor. The designer can use a built-in clock or use an external clock source. Data is transmitted at 10 or 40 SPS, depending on the setting. The supply voltage is in the range of 2. 6. . . 5. 5 V and the permissible operating temperature is from -40°C to +85°C. The system is available in the SOP-14 housing.

The HX720D is another 24-bit analog-to-digital converter with a built-in 3. 3-volt stabilizer. The built-in amplifier has a constant gain of 128 as well. Data is transmitted at 10 or 40 SPS, depending on the setting. The permissible operating temperature is -40°C to +85°C. The system is available in the SOP-8 housing.
