Description
The FHP3131 is a high-performance, voltage-feedback
amplifier that consumes only 0.4mA of supply current
while providing 70MHz of bandwidth and 50V/μs slew
rate. The FHP3131 is designed to operate from 2.5V to
12V (±6V) supplies. The common mode voltage range
extends below the negative rail and the output provides
rail-to-rail performance.
The FHP3131 is fabricated on a complementary bipolar
process. The combination of low power, rail-to-rail perfor-
mance, low voltage operation, and tiny package options
make this amplifier well suited for use in many general-
purpose, high-speed applications.
For power sensitive applications, the FHP3131 offers
unparalleled dynamic performance. It also offers a shut-
down feature to lower the supply current draw below
30μA. The FHP3131 is available in space-saving 6-lead
SOT23 or MicroPak™ packages and operates from -40°C
to +85°C.

Absolute Maximum Ratings
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be operable
above the recommended operating conditions and stressing the parts to these levels is not recommended. In addition,
extended exposure to stresses above the recommended operating conditions may affect device reliability. The absolute
maximum ratings are stress ratings only.
