FHP3131
0.4mA, 2.5V to 12V, 70MHz Rail-to-Rail Amplifier
February 2007
Features at +5V
Description
■ 0.4mA supply current
■ 70MHz bandwidth at unity gain
■ Power down to 30μA
■ Output voltage range at RL = 1kΩ : 0.07V to 4.8V
■ Input extends below negative rail: -0.3V to 4V
■ 50V/μs slew rate
■ 12nV/Hz input voltage noise
■ Small SOT23-6 and MicroPak™ -6 package options
■ Fully specified at +2.7V, +5V, and ±5V supplies
Applications
■ Portable/battery-powered applications
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.
■ A/D buffer
■ Active filters
■ Portable test instruments
■ Set-top box
■ HDTV
■ DVD players and recorders
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
