Parameter Test Conditions Min (1) Typ (2) Max (1) Units VOS Input Offset Voltage 1.2 7 mV TCVOS Input Offset Voltage Average Drift 2 µV/°C IB Input Bias Current 1.7 50 nA IOS Input Offset Current 0.6 40 nA CMRR Common Mode Rejection Ratio 0V ≤ VCM ≤ 1.7V 50 70 dB PSRR Power Supply Rejection Ratio 2.7V ≤ V+ ≤ 5V 50 65 dB VO = 1V, VCM = 1V VCM Input Common-Mode Voltage For CMRR ≥ 50 dB 0 −0.2 V Range 1.9 1.7 VO Output Swing RL = 100 kΩ to 1.35V V+ −100 V+ −3 mV 80 180 IS Supply Current LPV321-N 4 8 LPV358 8 16 Both Amplifiers µA LPV324 16 24 All Four Amplifiers (1) All limits are specified by testing or statistical analysis. (2) 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. 2.7V AC Electrical Characteristics Unless otherwise specified, all limits specified for TJ = 25°C, V + = 2.7V, V− = 0V, V CM = 1.0V, VO = V +/2 and R L > 1 MΩ. Parameter Test Conditions Min (1) Typ (2) Max (1) Units GBWP Gain-Bandwidth Product CL = 22 pF 112 kHz Φm Phase Margin 97 Deg Gm Gain Margin 35 dB en Input-Referred Voltage Noise f = 1 kHz 178 nV/ √Hz in Input-Referred Current Noise f = 1 kHz 0.50 pA/ √Hz (1) All limits are specified by testing or statistical analysis. (2) 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. 5V DC Electrical Characteristics Unless otherwise specified, all limits specified for TJ = 25°C, V + = 5V, V− = 0V, V CM = 2.0V, VO = V +/2 and R L > 1 MΩ. Boldface limits apply at the temperature extremes. Parameter Test Conditions Min (1) Typ (2) Max (1) Units VOS Input Offset Voltage 1.5 7 mV 10 TCVOS Input Offset Voltage Average Drift 2 µV/°C IB Input Bias Current 2 50 nA 60 IOS Input Offset Current 0.6 40 nA 50 CMRR Common Mode Rejection Ratio 0V ≤ VCM ≤ 4V 50 71 dB (1) All limits are specified by testing or statistical analysis. (2) 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.
