Transimpedance Amplifiers and Current-to-Digital Converters Turn even Minute
Signal Levels into Measurable Signals Quickly and Dynamically
Jena, Germany, 19 May 2015. Integrated signal amplifiers and converters from
MAZeT GmbH, specialized in the development and custom production of embedded
systems and optoelectronics, convert sensor signals from optical sensors in high
resolution and for the frequency and bandwidth required by the specific
application. The extended range of signal ASICs comprises the fast MTI04 and MTI08
transimpedance amplifiers and analog converters as well as the MDDC04AQ and
MCDC04EQ current-to-digital converters, featuring very high amplification and
bandwidth. MAZeT’s ASICs meet the demand in the area of signal electronics for fast
real-time signal conversion in inline processes as well as processing, for example,
extremely low sensor signal levels that are sometimes only slightly above the inherent
noise range.
“Optoelectronic sensors are semiconductor diodes with a power output; in many
technical applications, they also function as an individual receiver or as arrays for
light detection,” explains Frank Krumbein, Product Manager for Color and Spectral
Sensoring at MAZeT. “The application spectrum ranges from simple light barriers to
presence detection and optical fiber receivers for data transfer and imaging
equipment, such as scanners or digital cameras, right through to facilitating
measuring technology applications including the analysis of states, movements or
light-related parameters such as brightness or colors.”
All signal ASICs contain four or eight signal channels and can be dynamically
programmed in the process by means of multiple amplification levels. This makes
them very well suited for multi-channel sensor systems in applications with
dynamic amplification and a high sensor bandwidth. All converters feature highly
compact dimensions and are also available in space-saving (Q)SOP packages or
alternatively as COB technologies.

continuous signal processing at high signal frequencies, thus meeting the demands
of automated processes. They are best suited to synchronous measuring procedures in
the kilohertz range, where fast converters are required to scan optical signals.

Examples include sensors for quality testing in inline manufacturing processes or
those in touchless handheld devices. The MTI04 with analog output can convert up
to four photo currents per chip within an 8-pin programmable amplification level
featuring parallel signal output.
The MTI08 8-channel converter augments the functions of the MTI04 by adding
sample & hold as well as a multiplexer at the voltage output. To implement this,
MAZeT integrates a TIA with multiple channels into an ASIC and adds extra
functions such as programmability, power down, or multiplexer. This results in
reduced space requirements as compared with the discrete design, the temperature
coefficient of the amplification is lower, and the individual channels provide very
good synchronization properties across the gain stages.
Multi-Channel Current-to-Digital Converters
The MDDC04 and MCDC04AQ converters with digital outputs also feature highresolution on-chip AD conversion in addition to signal amplification and
temperature compensation and can be programmed using a digital interface. The
MDDC04 contains four current-voltage converters that work in cycles, and for each
channel 16 transimpedances can be separately adjusted in binary increments. Using
the maximum transimpedance, even currents in the nano-ampere range can be
measured quickly while covering a dynamic range of 30 dB. The chip is ideally
suited to higher signal frequencies in the kilohertz range and is therefore
recommended for fast synchronous measuring processes. The MCDC04AQ current-todigital converter converts photo currents from detectors via a continually integrating
load balance procedure and makes them available via an I²C interface as digital
data in 16-bit format on the output side. Due to the internal current load conversion
in the corresponding parameters, the signal ASIC is ideal for use in connection with
optical sensors for applications with very little light or with a high variance in
light that require the measurement of light in a broad range from very low to very
high levels of light. Other applications include light control with dimming or
