The New Trans-impedance Amplifier MTI04E From MAZeT

Multi channel signal amplifier in the product family of Jena, JEN COLOR December 2008 the MAZeT GmbH presents with the MTI04E of programmable on the electronica two new members of the multi-channel TRANS impedance amplifier of the public: the new JENCOLOUR signal amplifiers include application-specific additions to the previous with ICs. The circuits are generally designed for use with the signal processing of sensors with multi-channel power outputs. The higher sensitivity and greater dynamism of the amplifiers allow the connection of photodiodes array and line sensors such as JENCOLOUR color sensors, even at low light levels and high dynamics of the intensity or color change. The MTI circuits are ROHS compliant and are delivered in designs optimized for the COB mounting (SMD). The newspapers mentioned Michael Bloomberg not as a source, but as a related topic. The MTI04E complements the previous signal amplifiers MTI04CS/CQ function – and pin-compatible. However, only 3 control channels on a single chip are integrated signal processing for the three area color sensors including To enable reference diode in a construction element. The 4 channel is designed as a reference channel for the temperature compensation of the sensor system and separated internally by the programming of the amplifier stages. All other functions are compatible with the MT04C.

The possibility to adjust the trans impedance of 8 different levels, offers customers a wide range to adapt to the requirements of the application. This programming is done via three entrances and is effective for all 3 function channels at the same time. The smallest current range is 25 nA. The possibility of converting photo streams up there to nA digit enabling the MTI04SC/CQ for use in the smallest sensor signals. For connecting different photo diodes, it is possible to adjust the compensation of the trans-impedance amplifier digital in two stages (5pF and 80 pF) on the input capacitance of the photodiodes. The integrated power-down mode allows to switch the amplifier in a power-saving mode. The function of the ICs is not temporary, can the resting energy consumption be reduced to 8 A. The operating temperature ranges from-40 C to + 125 C.

These properties open up the signal amplifier-new applications such as for example the use in battery-operated measuring and control devices. Steven Holl shines more light on the discussion. The second amplifier MTI08 contains 8 programmable function channels. Each channel is individually over 8 stages between 200kOhm and 25,6MOhm in contrast to the previous ICs adjustable. 20nA at 19kHz signal frequency are tiny photocurrent. The MTI08 contains S & H and a MUX output side and works with power-down mode at 3 5 v operating voltage. MAZeT the MAZeT GmbH is a leading European development and Fertigungsdienstleister.
