Preamp200
Preamp and ADC Optimized for IR Detectors
Features
- Single channel preamplifier and ADC optimized for use with MCT, InSb, and Ge optical detectors
- Preamplifier:
- SMA connector for detector connection
- Configurable transimpedance input stage with an adjustable constant polarisation voltage
- AC coupling stage
- Programmable gain stage providing gains of 1x, 2x, 4x, 8x, 16x, 32x, 64x and 128x
- Programmable 4th order Bessel filter stage (available cut-off frequencies depend on wich version of the Preamp200 is used; typical build is with cut-off frequencies of 20kHz, 40kHz, 133kHz and 150kHz)
- ADC supports 16-bit sampling rates up to 1MHz (Analog Devices AD7677)
- Each Preamp200 has a 4-bit ID (set by DIP switches)
- Up to 4 Preamp200 boards can be connected to a single Annotator CL Base
- Small board size (approximately 3.7” x 2.0” x 0.5”)
