TI Unveils New OPA690/1/2 Operational Amplifiers

November 17, 2002 by Jeff Shepard

Texas Instruments Inc. (Dallas, TX) announced the completion of an eight-member family of high-speed operational amplifiers from the company's Burr-Brown product line that are suitable for DSL line drivers, video buffers and analog-to-digital converter input drivers. Covering a wide range of advanced system requirements, the family offers single-, dual- and triple-channel versions in either voltage-feedback (OPA690), current-feedback (OPA691) and fixed-gain video buffer (OPA692) topologies.

The OPA690 is a unity-gain-stable, voltage-feedback amplifier with optional disable that provides slew rate and full-power bandwidth. Using a single +5V supply, the OPA690 can deliver a 1V to 4V output swing with over 150mA drive current and 150MHz bandwidth. The OPA691 operates on a low 5.1mA supply current and offers a slew rate of 2,100V/µs and output power of 190mA, which makes it suitable for multi-line broadcast video interface applications. The OPA692 features a single 5V to 12V supply, a dual ±2.5 to ±6V supply, a ±190mA (±250mA current limit) output current, a 2,100V/µs slew rate, a ±4V output-voltage swing, and a dG/dP of 0.07 percent/0.02 degrees.

All eight devices are now available in all package versions. Pricing in 1,000-piece quantities starts for the single-channel versions at $1.50 (OPA690), $1.45 (OPA691) and $1.35 (OPA692).
