V + = 5V, V − = 0V, V CM = V +/2, V O = V +/2, R L > 1 MΩ and SHDN tied to V +. Boldface limits apply at the temperature extremes. See (1). Parameter Test Conditions Min (2) Typ (3) Max (2) Units PSRR Power Supply Rejection Ratio 1.8V ≤ V+ ≤ 5V 75 100 dB VCM = 0.5V 70 CMVR Input Common-Mode Voltage For CMRR TA = 25°C V− −0.2 −0.2 to 5.3 V+ +0.2 Range Range ≥ 50dB TA = −40°C to 85°C V− V+ V TA = 125°C V− +0.3 V+ −0.3 AV Large Signal Voltage Gain RL = 600Ω to 2.5V, 88 102 (LMV981-N Single) VO = 0.2V to 4.8V 87 dB RL = 2kΩ to 2.5V, 94 113 VO = 0.2V to 4.8V 93 Large Signal Voltage Gain RL = 600Ω to 2.5V, 81 90 LMV982 (Dual) VO = 0.2V to 4.8V 78 dB RL = 2kΩ to 2.5V, 85 100 VO = 0.2V to 4.8V 82 VO Output Swing RL = 600Ω to 2.5V 4.855 4.890 VIN = ±100mV (4) 4.835 0.120 0.160 0.180 V RL = 2kΩ to 2.5V 4.945 4.967 VIN = ±100mV 4.935 0.037 0.065 0.075 IO Output Short Circuit Current LMV981-N, Sourcing, VO = 0V 80 100 (5) VIN = 100mV 68 mA Sinking, VO = 5V 58 65 VIN = −100mV 45 Ton Turn-on Time from Shutdown 8.4 μs VSHDN Turn-on Voltage to enable part 4.2 V Turn-off Voltage 0.8 (5) Applies to both single-supply and split-supply operation. Continuous short circuit operation at elevated ambient temperature can result in exceeding the maximum allowed junction temperature of 150°C. Output currents in excess of 45mA over long term may adversely affect reliability. 5V AC Electrical Characteristics Unless otherwise specified, all limits ensured for TJ = 25°C. V + = 5V, V − = 0V, V CM = V +/2, V O = 2.5V, R L > 1 MΩ and SHDN tied to V +.Boldface limits apply at the temperature extremes. See (1). Parameter Test Conditions Min (2) Typ (3) Max (2) Units SR Slew Rate (4) 0.42 V/µs GBW Gain-Bandwidth Product 1.5 MHz Φm Phase Margin 71 deg Gm Gain Margin 8 dB en Input-Referred Voltage Noise f = 10 kHz, VCM = 1V 50 nV/ √Hz in Input-Referred Current Noise f = 10 kHz 0.08 pA/ √Hz (1) Electrical Table values apply only for factory testing conditions at the temperature indicated. Factory testing conditions result in very limited self-heating of the device such that TJ = TA. No ensured specification of parametric performance is indicated in the electrical tables under conditions of internal self heating where TJ > TA. See Application Note section for information on temperature derating of this device. Absolute Maximum Ratings indicated junction temperature limits beyond which the device may be permanently degraded, either mechanically or electrically. (2) All limits are specified by testing or statistical analysis. (3) Typical values represent the most likely parametric norm as determined at the time of characterization. Actual typical values may vary over time and will also depend on the application and configuration. The typical values are not tested and are not ensured on shipped production material. (4) Connected as voltage follower with input step from V− to V+. Number specified is the slower of the positive and negative slew rates.
