1 Overview
1.1 JFE150
The
JFE150
is an ultra-low-noise, low-gate-current, 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. The device is offered in 5-pin SOT23 and SC-70 packages.
1.2 JFE150EVM
The JFE150EVM is intended to provide basic functional evaluation of the JFE150 device. Key EVM features
include the following:
•
JFE150 Ultra-Low-Noise Pre-Amp
•
BNC connections for input and output
•
Convenient test points to all pertinent nodes
•
Resistor and capacitor through hole and surface mount pad options for critical signal paths
•
Banana plug connections for power supplies and bias nodes

1.4 Evaluation Module Limitations and Cautions
The default JFE150EVM configuration is designed to operate within the specified voltage and current regions
of the
JFE150
N-channel JFET and the
Take care by referencing the respective product data sheets to maintain specified operating conditions for
each device. In addition to observing the specified current and voltage levels, proper electrostatic discharge
precautions are advised when handling and applying the EVM.
1.5 Electrostatic Discharge Caution
Many of the components on the JFE150EVM are susceptible to damage by electrostatic discharge
(ESD). Customers are advised to observe proper ESD handling precautions when unpacking and
handling the EVM. Failure to observe ESD handling procedures may result in damage to the EVM
components.
