The OPA207 precision operational amplifier (op amp) replaces the industry standard OP-07, OP-77 and OP–177 amplifiers. The OPA207 offers improved noise, wider output voltage swing, and is twice as fast with half the quiescent current of the industry standard alternatives. Features include ultra-low input offset voltage and drift, low input bias current, high common-mode rejection ratio, and high power-supply rejection ratio.

The OPA207 op amp operates over a wide power-supply-voltage range, from ±2.25 V to ±18 V, with excellent performance. High performance is maintained as the amplifiers swing to their specified limits.

The OPA207 operational amplifier is easy to use and free from phase inversion and the overload problems found in some other operational amplifiers. The OPA207 is stable in unity gain and provide excellent dynamic behavior over a wide range of load conditions.
