5 / 33 page LMH6503 www.ti.com SNOSA78E – OCTOBER 2003 – REVISED APRIL 2013 Electrical Characteristics (1) (continued) Unless otherwise specified, all limits ensured for TJ = 25°C, VS = ±5V, AV(MAX) = 10, VCM = 0V, RF = 1kΩ, RG = 174Ω, VIN_DIFF = ±0.1V, RL = 100Ω, VG = +1V. Boldface limits apply at the temperature extremes. Parameter Test Conditions Min(2) Typ(2) Max(2) Units DC & Miscellaneous Performance GACCU Gain Accuracy (see Application VG =1.0V +0.25 +0.9/ −0.4 Information) 0V < VG < 1V ±0.3 +1.3/ −1.5 dB −0.7V < VG < 1V ±0.4 +4.4/ −4.3 G Match Gain Matching (see Application VG = 1.0 – ±0.7 Information) 0 < VG < 1V – +1.7/ −1.1 dB −0.7V < VG < 1V – +4.0/ −4.7 K Gain Multiplier (see Application 1.58 1.72 1.87 V/V Information) 1.58 1.91 VCM Input Voltage Range Pin 3 & 6 Common Mode, ±2.0 ±2.2 V |CMRR| > 50dB(6) ±1.80 VIN_ DIFF Differential Input Voltage Across pins 3 & 6 ±0.34 ±0.37 V ±0.28 IRG MAX RG Current Pins 4 & 5 ±1.70 ±2.30 mA ±1.60 IBIAS Bias Current Pins 3 & 6(7) 11 18 20 µA Pins 3 & 6(7), 3 10 VS= ±2.5V 13 TCBIAS Bias Current Drift Pin 3 & 6(8) 100 nA/°C I OFF Offset Current Pin 3 & 6 0.01 2.0 µA 2.5 TC IOFF Offset Current Drift See(8) 5 nA/°C RIN Input Resistance Pin 3 & 6 750 k Ω CIN Input Capacitance Pin 3 & 6 5 pF IVG VG Bias Current Pin 2, VG = 1.4V (7) 45 µA TC IVG VG Bias Drift Pin 2(8) 20 nA/°C R VG VG Input Resistance Pin 2 70 K Ω C VG VG Input Capacitance Pin 2 1.3 pF VOUT Output Voltage Range RL = 100Ω ±3.00 ±3.20 ±2.97 V RL Open ±3.95 ±4.05 ±3.90 ROUT Output Impedance DC 0.1 Ω IOUT Output Current VOUT ±4V from Rails ±75 ±90 mA ±70 VO OFFSET Output Offset Voltage −1V < VG < 1V ±80 ±350 mV ±380 +PSRR +Power Supply Rejection Ratio Input Referred, 1V change, −80 −58 dB (See(9)) VG = 1.4V −56 −PSRR −Power Supply Rejection Ratio Input Referred, 1V change, −67 −57 dB (See(9)) VG = 1.4V −51 CMRR Common Mode Rejection Ratio Input Referred, VG = 1V −67 dB (See(10)) −1.8V < VCM < 1.8V (6) CMRR definition: [| ΔVOUT/ΔVCM|/AV] with 0.1V differential input voltage. ΔVOUT is the change in output voltage with offset shift subtracted out. (7) Positive current correspondes to current flowing in the device. (8) Drift determined by dividing the change in parameter distribution at temperature extremes by the total temperature change. (9) +PSRR definition: [| ΔVOUT/ΔV +| /A V], -PSRR definition: [|ΔVOUT/ΔV −| /A V] with 0.1V differential input voltage. ΔVOUT is the change in output voltage with offset shift subtracted out. (10) CMRR definition: [| ΔVOUT/ΔVCM|/AV] with 0.1V differential input voltage. ΔVOUT is the change in output voltage with offset shift subtracted out.
