LMV981_15 Datasheet, PDF (8/21 Pages) Texas Instruments – LMV981 SINGLE, LMV982 DUAL 1.8-V OPERATIONAL AMPLIFIERS WITH RAIL-TO-RAIL INPUT AND OUTPUT AND SHUTDOWN
LMV981, LMV982
5V DC ELECTRICAL CHARACTERISTICS Unless otherwise noted, all min/max limits are guaranteed for TA = 25°C, V+ = 5 V,
V− = 0 V, VCM = V+/2, VO = V+/2 and RL > 1 MW. Typical specifications represent the most likely parametric norm.

9. Connected as voltage follower with input step from V− to V+. Number specified is the slower of the positive and negative slew rates.
10. Input referred, RL = 100 kW connected to V+/2. Each amp excited in turn with 1 kHz to produce VO = 3 VPP. (For Supply Voltages < 3 V,
VO = V+).
