is used to achieve
low

biasing
throughout results in
excell_entgain linearity over the full Input voltage range.
Applications for which the BUF-{)3is well-suited include
high-speed line drivers. isolation amplifiers
for driving
reactive loads. and high-speed sample-hold circuits.

NOTES;
1. In order 10operate the device at an ambienltemperatureot+ 125DC,more
extensive heat sinking must be used to ensure that the chip temperature
never exceeds Ihe absolute maximumot +175' C. The chip temperature of
+165.C Is achieved by reducing tl1ecase-to-ambient thermal resistance
to 30'CIW ie.g.. Thermalloy 2227).
2. Guaranteed by deeign.
