This unique configuration, enabled by the highly integrated 24-bit ADC, provides second and third dimensions of information about whatever object presses upon it.
The MAXREFDES82# reference design is:
- Fast – 64kS/s provides real time operation;
- Rugged – interface requires no special glass or material, making it suited for industrial environments;
- Precise – accurate measurements of weight and centre of mass up to 780g; and
- Low power – less than 50mA consumed during normal operation.
David Andeen, Director of Reference Designs, Maxim Integrated, commented: “Maxim’s smart force sensor reference design is a new concept, operating as both a weigh scale and 3D touch interface in rugged environments. MAXREFDES82# has a unique combination of a multi-channel, high resolution ADC with integrated programmable gain amplifiers and low power consumption, giving our customers speed and flexibility when designing industrial systems.”
The MAXREFDES82# reference design is available for $99. Hardware and firmware design files, as well as test data, are provided free and available online.
