12/20/2004 - Texas Instruments Incorporated (TI) (NYSE: TXN) announced a dual, high-output current, high-gain bandwidth operational amplifier from the company´s Burr-Brown product line. Featuring low input voltage noise with exceptionally low harmonic distortion, the OPA2614 provides high dynamic range for digital subscriber line (DSL) driver solutions in differential configurations.
Typical applications include driving 16-bit analog-to-digital converters, such as TI's ADS1605 16-bit, 5MSPS ADC, high-capacitive loads and multiple load video lines. The OPA2614 is also well suited for precision baseband I/Q receiver channels, low distortion audio amplifiers and active filters.
"The OPA2614 is an exceptional differential line driver through low to moderate frequencies. And the voltage feedback design gives the lowest total output noise for any currently available line driver solution," said Michael Steffes, strategic marketing manager of TI's high-speed signal processing group.
The amplifier has a flexible supply range of 5V to 12V for single condition and +/-2.5V to +/-6V for dual design. Single +5V operation as a differential I/O interface to ADC inputs can support 14- to 16-bit converters with no degradation in SNR or SFDR. Plus, the high power output stage of the OPA2614 can easily drive heavy filter loads.
Very high output current (350mA) coupled with a low gain stable design provides a good solution for driving large capacitive loads through moderate frequencies.
The OPA2614 is available now from TI and its authorized distributors in a standard SO-8 package in both plastic and PSO-8 thermally enhanced packaging with an exposed heat slug. The device is priced at $1.55 in 1,000 piece quantities (suggested resale pricing). For applications requiring very low gains or integrator-based filters, the OPA2613 (unity gain stable version) is recommended.
TI offers analog engineers a wide-ranging support infrastructure that includes training and seminars, design tools and utilities, technical documentation, evaluation modules, an online KnowledgeBase, a product information hotline and a comprehensive offering of samples that ship within 24 hours of request.
