DESCRIPTION
The OPA675 and OPA676 are wideband monolithic
operational amplifiers with two independent differen-
tial inputs. 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.
