APPLICATIONS

Instrumentation Buffer

RF Buffer

Line Driver

High Speed Current Source

Op Amp Output Current Booster

High Performance Audio

High Speed AD/DA

High slew rate and very low noise and THD, coupled with wide

input and output dynamic range, make the BUF04 an excellent

choice for video and high performance audio circuits.

The BUF04’s inherent ability to drive capacitive loads over a

wide voltage and temperature range makes it extremely useful

for a wide variety of applications in military, industrial, and

commercial equipment.

The BUF04 is specified over the extended industrial (–40

°C to

+85

°C) and military (–55°C to +125°C) temperature range.

BUF04s are available in plastic and ceramic DIP plus SO-8

surface mount packages.

availability.

*Patent pending.

GENERAL DESCRIPTION

The BUF04 is a wideband, closed-loop buffer that combines

state of the art dynamic performance with excellent dc

performance. This combination enables designers to maximize

system performance without any speed versus dc accuracy

compromises.

Built on a high speed Complementary Bipolar (CB) process for

better power performance ratio, the BUF04 consumes less than

8.5 mA operating from

±5 V or ±15 V supplies. With a 2000 V/µs

min slew rate, and 100 MHz gain bandwidth product, the

BUF04 is ideally suited for use in high speed applications where

low power dissipation is critical.

Full

±10 V output swing over the extended temperature range

along with outstanding ac performance and high loop gain

accuracy makes the device useful in high speed data acquisition

systems.
