The 312B Series are ultra low noise, high gain, GaAs FET amplifiers designed for low level current source input applications in which high gain is required.
- ULTRA LOW NOISE – DOWN TO 1 pA/√Hz
- HIGH GAIN – 1 MV/A
- BANDWIDTH – DC or 200 Hz TO 65 MHz
- ACCEPTS CURRENT SOURCE INPUTS
- DIRECTIVE 2011/65/EU (RoHS II) COMPLIANT
Transimpedance amplifiers have a virtual ground input. The capacitance of the current source and any cabling reduces the bandwidth and increases the noise. To optimize bandwidth and noise performance AMI compensates the input stage of the Model 312B transimpedance amplifier for the end user’s source capacitance. The options are shown in the table below:
Please contact AMI to discuss your application or if you have any questions.
