  • Page 3: Overview

    N-channel JFET capable of operating over a wide drain-to- source voltage of up to 40 V and a gate-to-drain voltage down to –40 V. The JFE150 yields excellent noise performance for currents from 50 μA to 20 mA with extremely high input impedance (> 1 TΩ). When biased at 5 mA, the device yields 0.8 nV/√Hz.
  • Page 4: Getting Started

    Figure 4-2. If dual-supply operation is required, VSS can be powered separately; adjust components R25 and R12 to bias the JFE150 to the desired bias point. Set Vbias to midsupply, as discussed in section Section 2.3. 2.2 Input The input to the JFE150EVM is designed to interface high-impedance sources to the gate of the JFET.
  • Page 5: Application Circuit

    VDD = 12 V and VSS = GND. The output voltage, Vout, settles to approximately midsupply or 6 V, as shown in Figure 3-1. A theoretical explanation of the preamplifier with a JFE150 front end in a closed-loop circuit is detailed in the JFE150 Ultra-Low-Noise- Pre-Amp application report.
