Either input can be selected by an external logic signal. The OPA675 is compatible with ECL logic while the OPA676 is TTL compatible. Both amplifiers are externally compensated and feature very fast input selection speed: ECL = 4ns, TTL = 6ns. This amplifier features fully symmetrical differential inputs due to its “classical” operational amplifier circuit architecture. Unlike “current-feedback” amplifier designs, the OPA675/676 may be used in all op amp applications requiring high speed and precision. Low distortion and crosstalk make these amplifiers suitable for RF and video applications. The OPA675 and OPA676 are available in KG (0°C to +70°C) and SG (–55°C to +125°C) grades. All grades are packaged in a 16-pin DIP. _ Input A + A Output _ Input B + TTL: OPA676 ECL: OPA675 International Airport Industrial Park • Mailing Address: PO Box 11400 • Tucson, AZ 85734 • Street Address: 6730 S.
