Texas Instruments BUF802 buffering operational amplifier

Mouser Electronics, Inc., now stocks the BUF802 high-speed buffering operational amplifier from Texas Instruments (TI). The operational amplifier is designed to increase signal bandwidth in data acquisition systems, enabling design engineers to scale front-end designs across multiple data-acquisition applications for a variety of test and measurement applications, including oscilloscopes, active probes and high-frequency data-acquisition systems.

The buffering op amp is a high-input impedance (Hi-Z), open-loop, unity gain buffer amplifier with a JFET-input stage that offers wide bandwidth capable of supporting frequency bandwidths up to 3.1 GHz. Replacing complex ASIC-based design implementations, the buffering op amp integrates features of discrete components in a single chip that considerably increases bandwidth, compared to FET-input amplifiers. This performance lets design engineers leverage high signal throughput with minimal input settling time, leading to faster throughout and improved accuracy in higher-frequency signal measurement.

For development, Mouser also stocks the BUF802RGTEVM evaluation module, which features two separate signal configurations: a composite loop with a precision amplifier and the standalone BUF802 buffer. The BUF802RGTEVM features single or split supplies and footprints for SMA connectors into all analog inputs and outputs. Additionally, the layout is optimised to reduce parasitic coupling and provide the best signal fidelity across frequency.
