Low-noise preamplifier selection guide

Compact, wide-bandwidth current-to-voltage conversion module

  • I/V conversion of high-frequency signals up to 10MHz
  • Combines high gain with wide frequency response

Lineup

Gain (V/A) Frequency response Equivalent input noise current density
IV-202F4 100k DC to 10MHz 450fA/√Hz
IV-204F3 4M DC to 1MHz 70fA/√Hz

*The IV-200 series supports customization of the frequency response according to the capacitance of the sensor connected to the input.

Input voltage - Frequency response

Wide measurement range: 1nA to 100µA

The IV-204F3 (up to 1MHz) is recommended for input current ranges between 1nA and 100nA, and the IV-202F4 (up to 10MHz) is recommended for currents above 100nA.
