PICOCAP Capacitive Sensing
PICOCAP is a Capacitance-to-Digital Converter (CDC) which uses the patented PICOCAP measuring principle to interface to a broad range of capacitive sensors. The input capacitance can range between a femtoFarad and hundreds of nanoFarads, which means that there is almost no limit to the size of capacitor. The multi-channel CDC provides a high degree of flexibility with respect to accuracy, speed and operating current. A powerful integrated CPU enables on-chip linearization and temperature measurement and compensation.
Product overview
PCAP04 Capacitance-to-Digital Converter
PCap04 is a capacitance-to-digital converter (CDC) with integrated digital signal processor (DSP) for on-chip data post-processing. Its front end is based on the PICOCAP principle. This conversion principle offers outstanding flexibility with respect to power consumption, resolution and speed. Further, PCap04 covers a wide capacitance input range from a few femtofarads up to several hundreds of nanofarads. It is easy to configure the PCap04 for different capacitance measurement tasks, i.e. single as well as differential sensors in both, grounded or floating connection. The on-chip DSP allows to implement sensor algorithms like linearization and temperature compensation, with data output in a digital (SPI or IIC) or analog (PDM/PWM) way.
PCAP02 Capacitance-to-Digital Converter
Low power capacitance-to-digital converter with wide input range (from fF to nF) and versatile configuration options. PCap02 can be configured for highest sampling rates up to 500kHz, lowest current consumption down to 2µA or lowest noise of 15 aF (rms). The internal signal processor allows for power-efficient and fast calculations, e.g. for sensor linearization or complex arithmetics.
PCAP01 Capacitance-to-Digital Conversion Digital Signal Processor
PCapØ1 is a dedicated Capacitance-to-Digital Conversion Digital Signal Processor. Its front end is based on acam‘s patented 4→ principle. This conversion principle offers high resolution at conversion times as short as 2 µs. Customers benefit from outstanding flexibility for optimizing power consumption, resolution and speed.
PICOSTRAIN Resistive Sensing
The Resistance-to-Digital Converters (RDCs), based on the pure digital PICOSTRAIN measuring principle, combine very high precision with very low power consumption. Featuring an on-chip CPU, the PICOSTRAIN devices enhance the performance of resistive pressure sensors, force sensors, weighing scales and many other applications.
Product overview
PS081 Resistance-to-Digital Converter
The PSØ81 is a system on chip for ultra low power and high resolution applications. It was designed especially for weight scales but fits also to any kind of force or torque measurements based on metal strain gauges. It takes full advantage of the digital measuring principle of PICOSTRAIN. Thus, it combines the performance of a 28-bit signal converter with a 24-bit microprocessor. Additional elements like an LCD driver, 3K ROM with many complex pre-defined functions, 2k EEPROM program memory and an integrated 10kHz oscillator round off the device. A small amount of external components is sufficient to build a complete weighing electronic.
PS09 Resistance-to-Digital Converter
The PSØ9 is a system on chip for ultra low power and high resolution applications. It was designed especially for weight scales but fits also to any kind of force, pressure or torque measurements based on metal strain gauges. It takes full advantage of the digital measuring principle of PICOSTRAIN. Thus, it combines the performance of a 28-bit converter with a 24-bit microprocessor.
