Maxim Integrated MAXREFDES82# smart force sensor reference design

Design engineers can now rapidly evaluate and deploy human-machine interface (HMI) devices using the MAXREFDES82# smart force sensor reference design from Maxim Integrated.

Typical weigh scales provide one dimension of information: downward force. The reference design provides both downward force and centre of mass by collecting responses from four load cells using the MAX11254, a 24-bit, 6-channel analog-to-digital converter (ADC). This configuration, enabled by the integrated 24-bit ADC, provides second and third dimensions of information about whatever object presses upon it.

The interface requires no special glass or material, making it suitable for industrial environments. It offers measurements of weight and centre of mass up to 780 g. Less than 50 mA is consumed during normal operation.

The product operates as both a weigh scale and 3D touch interface in rugged environments. It features a combination of a multichannel, high-resolution ADC with integrated programmable gain amplifiers and low power consumption, providing users with speed and flexibility when designing industrial systems.
