3 Description

The JFE150 is a Burr-Brown? discrete JFET built

using Texas Instruments' modern, high-performance,

analog bipolar process. The JFE150 features

performance not previously available in older discrete

JFET technologies. The JFE150 offers the maximum

possible noise-to-power efficiency and flexibility,

where the quiescent current can be set by the user

and yields excellent noise performance for currents

from 50 μA to 20 mA. When biased at 5 mA, the

device yields 0.8 nV/√Hz of input-referred noise,

giving ultra-low noise performance with extremely

high input impedance (> 1 TΩ). The JFE150 also

features integrated diodes connected to separate

clamp nodes to provide protection without the addition

of high-leakage, nonlinear, external diodes.

The JFE150 can withstand a high drain-to-source

voltage of 40 V, as well as gate-to-source and gateto-

drain voltages down to –40 V. The temperature

range is specified from –40°C to +125°C. The device

is offered in 5-pin SOT-23 and SC70 packages.
