DESCRIPTION
The SSTD89A n-channel JFET features built-in self-biased
diodes and is designed to provide low voltage, low noise
and low cut-off voltage. It can be used with power supplies
as low as 1.2 V. The SSTD89A is ideal for use in low
current amplifier, hearing aid and mini-microphone
applications.
The SSTD89A is available in the SC-70 (SOT-353), 5-lead
package.
