FHP3131

FHP3131 0.4mA, 2.5V to 12V, 70MHz Rail-to-Rail Amplifier February 2007 FHP3131 0.4mA, 2.5V to 12V, 70MHz Rail-to-Rail Amplifier Features at +5V ■ 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 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 performance, low voltage operation, and tiny package options make this amplifier well suited for use in many generalpurpose, high-speed applications. Applications ■ Portable/battery-powered applications ■ A/D buffer ■ Active filters ■ Portable test instruments ■ Set-top box ■ HDTV ■ DVD players and recorders ■ Coaxial cable drivers ■ Video driver For power sensitive applications, the FHP3131 offers unparalleled dynamic performance. It also offers a shutdown feature to lower the supply current draw below 30μA. The FHP3131 is available in space-saving 6-lead SOT23 or Mi...
