Now at Mouser: TI’s BUF802 Buffering Op Amp

Removes Complexity in Measurement DAQ Front Ends


Mouser Electronics, Inc., the industry’s leading New Product Introduction (NPI) distributor with the widest selection of semiconductors and electronic components, is now stocking the BUF802 high-speed buffering operational amplifier from Texas Instruments (TI). The BUF802 exponentially increases 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 TI BUF802, available from Mouser Electronics, is a high-input-impedance (Hi-Z), open-loop, unity gain buffer amplifier with a JFET-input stage that offers the industry’s widest bandwidth, capable of supporting frequency bandwidths up to 3.1 GHz. Replacing complex and costly ASIC-based design implementations, the BUF802 integrates features of discrete components in a single chip that increases bandwidth tenfold compared to FET-input amplifiers. This performance lets design engineers leverage higher signal throughput with minimal input settling time, leading to faster throughput 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 optimized to reduce parasitic coupling and provide the best signal fidelity across frequency.
