ASIC-level wide bandwidth performance, minimal input stabilization time

Texas Instruments (TI) introduces an amplifier that addresses engineers' needs by eliminating the need for custom ASICs and simplifying front-end design.

TI announced on the 20th that it is launching the 'BUF802', a high-input impedance (Hi-Z) buffer amplifier with the industry's largest bandwidth of up to 3 GHz.

The BUF802 increases signal throughput and minimizes input settling time through its wide bandwidth and high slew rate.

Engineers can leverage the BUF802's fast throughput to more accurately measure high-frequency signals in test and measurement applications such as oscilloscopes, active probes, and high-frequency data acquisition systems.

TI's BUF802 provides a single-chip solution that can replace the performance of products based on ASICs or FET input amplifiers by integrating the functions of components.

Additionally, it delivers performance comparable to custom ASICs by providing 10 times wider bandwidth than FET input amplifiers in data acquisition systems.

The BUF802 is the industry's first buffer amplifier capable of regulating the bandwidth from 100 MHz to 3 GHz at 1 V peak-to-peak (VPP) and up to 2 GHz at 2 VPP, as well as the quiescent current according to signal swing requirements.

Bandwidth and signal swing like thisThe wide range of adjustments allows engineers to easily scale front-end designs across multiple data acquisition applications, making them easier to redesign and cost-effective.

Integrated function mode allows engineers to use the BUF802 as a standalone buffer or in a complex loop with a precision amplifier such as the OPA140.

Using the BUF802 as a standalone buffer allows for 100mV offset voltage while achieving high input impedance and high slew rate in AC-coupled signal channel applications.
