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

鈥渃lassical鈥?operational amplifier circuit architecture.

Unlike 鈥渃urrent-feedback鈥?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擄C to

+70擄C) and SG (鈥?5擄C to +125擄C) grades. All grades

are packaged in a 16-pin DIP.
