MEASUREMENT PRINCIPLE
The TZA300 series of amplifiers employs
precision dual transimpedance input
stages to provide for high common mode
rejection and linearity throughout the full
dynamic range. The differential input stage
design requires a floating current input. If
the application involves a grounded
current source, a single ended amplifier
must be used.

LEDs via a variety of photodiodes for
these applications such as Si and InGaAs.
The TZA300 series is insensitive to
electromagnetic interference by design, an
important factor when working in „dirty“
industrial environments. The case wings
provide for mounting on standard 25mm
and 1“ optical table tops and for OEM
applications. 19“ rack mounting is also
available.

FIELDS OF APPLICATION
These transimpedance amplifiers are
particularly useful for the measurement of
current from photodiodes. The output is a
voltage linearly proportional to input
current and thus, to input power in
photodiode monitoring applications. The
fast response time at high signal-noiseratio makes the TZA300 series particularly
useful in systems control feedback loops.
The high sensitivity and large dynamic
range allow measurement of a wide range
of optical sources such as lasers and
