As you may notice -- this is not a new product but one introduced in the very beginning of this year. We somehow missed posting the product and wanted you to know about it because it is a significant product that you should keep on file for future designs.
Tucson, AZ. (Jan. 14, 2004) -- Texas Instruments Incorporated (TI) announced a low-power, current-feedback amplifier from the company's Burr-Brown product line, which offers unmatched bandwidth at low and high gains. The device is designed for applications in video signal processing, cable modems, wireless communications and test instrumentation.
At higher gains (G = +8), the OPA695 offers 4300V/μsec slew rate and >450MHz bandwidth, providing a low-power solution for Intermediate Frequency (IF) amplifier applications. Capable of single supply +5V to +12V operation, the OPA695 gives an improved output intercept at lower power than existing dedicated IF amplifiers. At lower gains (G = +2), popular for video line driving, the OPA695 offers 1.4GHz bandwidth with 2500V/μsec slew rate, covering the highest speed video requirements.
The low 12.9mA supply current is precisely trimmed at +25°C. This trim, along with low quiescent current shift over a wide temperature range, gives low system power over temperature. Fully specified over both the commercial (0°C to +70°C) and industrial temperature (-40°C to +85°C) ranges, the OPA695 shows minimal drop-off in performance at the temperature extremes. Using the optional disable control pin, the OPA695 supply current may be further reduced to less than 170μA. This power-saving feature, along with exceptional single +5V operation and ultra-small SOT23-6 packaging, will be attractive to wideband amplifier requirements in portable applications.
Additional features include low input voltage noise (1.8nV/rtHz), high 3rd-order intercept (>30dBm through 120MHz), high output swing (+/-4.2V on +/-5V supply) and instrumentation level dG/dP (0.04%/0.01°) for composite video applications.
The OPA695 is packaged in both an SO-8 and SOT23-6 in industry standard pinouts. The OPA695ID (SO-8 package) is available now from TI and its authorized distributors. The device is priced from $1.35 in 1,000 piece quantities (suggested resale pricing). The OPA695IDBV (SOT23-6 package) is available now.
