PICOCAP® 정전용량 감지

PICOCAP는 CDC (capacitive-to-digital converter)입니다. 특허로 되어 있는 PICOCAP 측정 원리는 휘발성 기법으로 광범위한 범위의 용량성 센서를 측정할 수 있도록 제공됩니다. 입력 용량은 fF ~ 수 백 nF 사이의 범위에서 존재할 수 있으며, 따라서 커패시터 크기에 대한 제한은 현실적으로 존재하지 않습니다. 멀티 채널 CDC는 정밀도, 속도, 초저전력 동작 관점에서 고도의 유연성을 제공합니다. 통합형의 강력한 CPU는 온칩 선형화, 온도 측정 및 보상을 가능하게 합니다.

PCap02

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.

PCap04

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 ams 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.

시그널 컨버터

ams 신호 변환기에는 4개 또는 8개의 신호 채널이 탑재되어 있어서 여러 증폭 레벨을 통해 프로세스 도중에 동적으로 프로그램될 수 있습니다. 따라서 동적 증폭과 높은 센서 대역폭이 적용되는 다채널 센서 시스템에 매우 적합합니다. 이들 변환기는 모두 소형이므로 공간을 줄여주는 (Q)SOP 패키지나 COB (Chip-on-Board, 칩 온 보드) 패키지로 제공됩니다.

AS89000

The AS89000-devices are a family of integrated circuits of programmable gain transimpedance amplifiers with 4 channels per IC (more custom specific, on request). The AS89000-devices are mainly used for signal conditioning of sensors with current outputs. They are especially suitable for connection of photodiodes of array and row sensors. The possibility to adjust the transimpedance in 8 stages is a special feature. The adjustment is made by programming three pins and is valid for all channels together. The device packages (naked chip on request) are RoHS conform and optimized for COB- mounting and SMD.

AS89010

The AS89010 processes via charge-balance method and converts lowest photo-currents at high accuracy. Its full-scale range can be customized to specific applications. Sensitivity of 20 fA/LSB at a dynamic of 1 to 1,000,000. The IC is temperature compensated and features the possibility of external synchronization.

AS89020

The AS89020 is a 12-bit, 4 channel, current input Analog-to-Digital Converter (ADC). It combines current-to-voltage (TIA) and analog-to-digital (AD) conversion, so that 4 separate current output devices (e.g. photodiodes) can be directly connected to its inputs and digitized. For each of the 4 inputs the AS89020 provides an input amplifier with a track and hold circuit. The outputs of the track and hold stages are serial converted to 12-bit digital words using an analog-to-digital converter (ADC).

PS081

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

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.

AS8510

The AS8510 data acquisition front-end IC is a virtually offset free, low noise, 2-channel measurement device. It is tailored to accurately measure battery current from mA range up to kA range in combination with a 100 µOhm shunt resistor connected in series with the battery rail. Through the second measurement channel it enables capture of either battery voltage synchronous with the current or to measure the analog output of an internal or external temperature sensor.
