PSØ81 - The Innovation in Strain Gauge Electronics goes on

The PS081 is the latest addition to the PICOSTRAIN product familiy of integrated circuits for measuring strain gauges. As a PS08 derivative, the PS081 also combines an ultra low power 24-Bit microprocessor with a high resolution T/D-converter (TDC) according to the known PICOSTRAIN measuring principle. An LCD controller and an EEPROM makes it a full featured System on Chip. Equipped with an extended memory range, enlarged ROM routines, enhanced IO-capabilities and an optional interface for external LCD driver control, the PS081 fulfills all requirements of coming generations of weigh scales, force sensors, pressure sensors or torque measurement systems in the consumer and the industrial market.

The most powerful combination of low power and highest accuracy

The unique  combination of a low power microprocessor with the PICOSTRAIN measuring unit shows impressive performance. The device reaches more than 28-Bit rms resolution and its excellent linearity and drift numbers are only comparable to absolute high-end Sigma-Delta A/D-converters. On the resolution side the PS081 makes it possible to get up to150,000 stable peak to peak divisions (at 2mV/V)! On the other hand a sophisticated power management together with the special features of the PICOSTRAIN method can reduce the total system current down to 15 µA, including the sensor current. Since the device is specified down to 2.2V it  can be driven by a single lithium coin cell for a very long time. This will save costs and offers great advantages for wireless and battery driven systems.
Further features like the software adjustment of the offset and gain compensation or the possibility to operate with only one halfbridge opens the door to new and innovative solutions.
