The Fast One!
- Fast
- Wide dynamic range
- Compact
The transimpedance amplifier TZA200 is designed for precise, high speed measurement of current in the µA to mA range. The output is a voltage linearly proportional to the input current.
The gain of the TZA200 is fixed.
- Receptacles: BNC (input and output)
- Rise time: 35ns (10MHz)
- Bandwidth (-3dB): 10MHz
- Noise equivalent current: 1 µA(RMS)
- Gain control: none
The TZA200 amplifier employs precision single ended transimpedance input stages to provide for low offset and high linearity throughout the full dynamic range. The single ended input stage is required for applications where the current source is inherently grounded externally.
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-noise-ratio makes the TZA200 series particularly useful in systems control feedback loops.
These amplifiers have a particularly high bandwidth of 10MHz allowing monitoring of high frequency noise components of many light sources.
The TZA200 series is insensitive to electromagnetic interference by design, an important factor when working in „dirty“ industrial environments. These units are provided in OEM-style enclosures. The case wings provide for mounting on standard 25mm and 1“ optical table tops and for OEM applications.
