Cable receivers boast bigger dynamic range
Mazet has released fully functional prototypes of its newly developed fibre-optic cable receivers, which will be available as standard assemblies in larger batches in the second half of the year.
Sensors show their true colours in Nuremberg
Mazet is set to satisfy demands for true colour sensors by launching its Jencolour true colour portfolio just in time for Sensor + Test 2005 in Nuremberg.
The new MTI04CS/CQ is designed to work with Mazet's Jencolour product family as well as a wide range of other applications.
The MTI04CS/CQ offers the ability to adapt the compensation of the transimpedance amplifier to the input capacitance of the sensors, such as photodiodes.
This is done digitally in two stages, 5 and 80pF.
Programming of the transimpedance gain is carried out via three input pins to any of eight levels, and takes effect for all channels simultaneously.
The MTI04CS/CQ integrates four channels on a single chip, but it is possible to increase the number of channels if required by the customer.
Combined with naked chip (die) manufacturing and corresponding sensors, surface optimised receiver modules are possible.
When cascaded, these can be laid out as scanning row modules.
To increase the input sensitivity compared with previous ICs, the amplification has been increased by a factor of four (from 5 to 20Mohm) and the noise has been minimised.
The smallest current measurement range is now 25nA.
Initial tests have verified the low noise and higher amplification of the IC.
The new MTI04CS/CQ is therefore ideal for the conversion of the smallest photo currents in the lower nanoamp range or the conversion of very high input frequencies in the upper kilohertz or even megahertz range.
Also new, the power-down mode of the MTI04CS/CQ allows the IC to be operated in power saving mode.
Because of its of multiple channels, programmability, sensitivity and bandwidth, the MTI04CS/CQ is particularly suited for use as amplifiers for sensors such as opto arrays and rows in the UV, VIS, NIR and IR regions.
This is also true for typical applications such as industrial sensor technology (light grid, length, filling level, position, thickness and distance measurement), equipment for surface analysis and temperature measurement (thermal imaging, combustion supervision), detectors for alpha, beta, gamma and X-rays and ions as well as applications for measurement, regulation and control of light and laser sources.
