V + = 2.7V, V − = 0V, V CM = 1.0V, VO = 1.35V and RL > 1 MΩ. Boldface limits apply at the temperature extremes. Symbol Parameter Conditions Typ(1) Units SR Slew Rate See(2) 0.41 V/µs GBW Gain-Bandwidth Product 1 MHz Φm Phase Margin 65 Deg. Gm Gain Margin 10 dB en Input-Referred Voltage Noise f = 1 kHz, VCM = 0.5V 45 nV/ √Hz in Input-Referred Current Noise f = 1 kHz 0.1 pA/ √Hz THD Total Harmonic Distortion f = 1 kHz, AV = +1 0.077 % RL = 600kΩ, VIN = 1 VPP Amp-to-Amp Isolation See(3) 140 dB (1) Typical Values represent the most likely parametric norm. (2) V+ = 5V. Connected as voltage follower with 5V step input. Number specified is the slower of the positive and negative slew rates. (3) Input referred, V+ = 5V and RL = 100kΩ connected to 2.5V. Each amp excited in turn with 1kHz to produce VO = 3VPP. Copyright © 2000–2013, Texas Instruments Incorporated Submit Documentation Feedback 5 Product Folder Links: LMV921 LMV922 LMV924 |
