Mouser Electronics stocks TI’s latest 8GHz op amp

Distributor, Mouser Electronics now stocks Texas Instruments’ OPA855, a decompensated amplifier.

The OPA855 is designed as a wideband, low-noise, bipolar-input operational amplifier and is claimed to excel in high bandwidth transimpedance and voltage amplifier applications. The 8GHz gain-bandwidth product (GBWP) enables high-gain configurations while maintaining wide closed-loop bandwidth, confirms Mouser. The low input-voltage noise of 0.98nV/√Hz minimises noise contribution from the amplifier and the high slew rate of 2750 V/ micro seconds enables wide output voltage swings.

For transimpedance amplifier (TIA) applications the OPA855 has a low input capacitance of only 0.8 pF, which minimises the total circuit input capacitance and enables higher-speed designs, says Mouser. The package pinout simplifies the layout of the feedback network while simultaneously isolating pin-to-pin capacitance between the input and feedback connections. This pinout design reduces the total parasitic capacitance around the amplifier’s feedback network, allowing for high-gain TIA designs to achieve wide bandwidth.

The OPA855 joins the FET-input OPA858 and OPA859 devices by Texas Instruments. This family of amplifiers can be used for wideband transimpedance circuits as well as high-speed data acquisition systems and low-noise front ends.

The TI OPA855DSGEVM op amp evaluation module and the general-purpose DEM-OPA-WSON8-EVM unpopulated evaluation board are also available from Mouser.

Mouser claims to stock the world’s widest selection of the latest semiconductors and electronic components. Mouser Electronics’ website is continually updated and offers advanced search methods to help customers quickly locate inventory. It also houses datasheets, supplier-specific reference designs, application notes, technical design information and engineering tools.
