ISL28191_0808 Datasheet, PDF (4/16 Pages) Intersil Corporation – Low Distortion Rail-to-Rail Output, Op Amp

ISL28191, ISL28291
Electrical Specifications
V+ = 5.0V, V- = GND, R_L = Open, R_F = 1kΩ, A_V = -1 unless otherwise specified. Parameters are per amplifier.
Typical values are at V+= 5V, T_A = +25°C. Boldface limits apply over the operating temperature range,
-40°C to +125°C, temperature data guaranteed by characterization. (Continued)
