Typical Characteristics: VS = 5.0 V (continued)

at VS+ = 5.0 V, VS– = 0 V, VOUT = 2 VPP, RF = 0 Ω, RL = 2 kΩ, G = 1 V/V, input and output referenced to mid-supply, and TA ≈

25°C (unless otherwise noted)

See Figure 74, gain = 2 V/V,

input edge rate set to stay below slew limiting

Figure 7. Noninverting Step Response vs Time and VOPP

See Figure 75, gain = –1 V/V,

input edge rate set to stay below slew limiting
