- TM7711 24bit ADC module for wlectronic weighting sensors. This chip is very similar to HX710A, but costs less. It’s designed for weigh scales and industrial control applications to interface directly with a bridge sensor. The TM7711 is an ideal product for high-precision weigh scale systems with a special structure to ensure extremely low power consumption.
- And built-in power-down mode to reduce standby power consumption. The chip also has the advantages of high integration, fast response, strong anti-interference, etc. Greatly reduces the overall cost of the electronic scale system and improve the performance and reliability of the whole system.
- This chip converts a single analog channel input to a digital signal with a high resolution, 24Bit precision. In this module, to achieve higher precision, input analog signal attains from a bridge-bridged voltage sensor (e.g. pressure, weighing) mode.
- The input voltage signal is produced by 3 resistors and a weight sensor configured as a Watson bridge (named and released as a load-cell device), then the TM711 converts and amplifies this load-cell signal, then sends converted voltage to micro-controller preparing it for further uses.
