LTC6405 Dc electrical characteristics The l denotes the specifications which apply over the fulloperating temperature range, otherwise specifications are at TA = 25°C. V+ = 5V, V– = 0V, VCM = VOCM = VICM = 2.5V, VSHDN = open,circuit component values in Figure 1 used, unless otherwise noted. VS is defined as (V+ – V–). VOUTCM is defined as (V+OUT + V–OUT)/2.VICM is defined as (V+IN + V–IN)/2. VOUTDIFF is defined as (V+OUT – V–OUT).SYMBOLPARAMETERCONDITIONSMINTYPMAXUNITS VOSDIFF Differential Offset Voltage (Input Referred) VICM = 5V (Note 12) l ±1 ±7 mV VICM = 2.5V l ±0.5 ±3.5 mV VICM = 0V (Note 12) l ±1 ±7 mV ∆VOSDIFF/∆T Differential Offset Voltage Drift (Input Referred) VICM = 5V (Note 12) l 1.5 µV/°C VICM = 2.5V l 1 µV/°C VICM = 0V (Note 12) l 3 µV/°C IB Input Bias Current (Note 6) VICM = 5V 8 µA VICM = 2.5V l –24 –7 µA VICM = 0V –14 µA IOS Input Offset Current (Note 6) VICM = 5V ±0.5 µA VICM = 2.5V l ±0.5 ±4 µA VICM = 0V ±0.5 µA RIN Input Resistance Common Mode 230 kΩ Differential Mode 3.5 kΩ CIN Input Capacitance Differential 1 pF en Differential Input Referred Noise Voltage Density f = 1MHz, Not Including RI/RF 1.6 nV/√Hz Noise in Input Noise Current Density f = 1MHz, Not Including RI/RF 2.4 pA/√Hz Noise enVOCM Input Referred Common Mode Output Noise Voltage f = 1MHz 9.5 nV/√Hz Density VICMR (Note 7) Input Signal Common Mode Range Op-Amp Inputs l V– V+ V CMRRI Input Common Mode Rejection Ratio VICM from 0V to 5V l 50 75 dB (Note 8) (Input Referred) ∆VICM/∆VOSDIFF CMRRIO Output Common Mode Rejection Ratio VOCM from 0.5V to 3.9V l 50 75 dB (Note 8) (Input Referred) ∆VOCM/∆VOSDIFF PSRR Differential Power Supply Rejection VS = 4.5V to 5.25V l 50 75 dB (Note 9) (∆VS/∆VOSDIFF) PSRRCM Output Common Mode Power Supply Rejection VS = 4.5V to 5.25V l 55 70 dB (Note 9) (∆VS/∆VOSCM) GCM Common Mode Gain (∆VOUTCM/∆VOCM) VOCM from 0.5V to 3.9V l 1 V/V ∆GCM Common Mode Gain Error 100 • (GCM – 1) VOCM from 0.5V to 3.9V l ±0.25 ±0.8 % BAL Output Balance (∆VOUTCM/∆VOUTDIFF) ∆VOUTDIFF = 2V Single-Ended Input l –60 –40 dB Differential Input l –65 –40 dB VOSCM Common Mode Offset Voltage (VOUTCM – VOCM) l ±6 ±15 mV ∆VOSCM/∆T Common Mode Offset Voltage Drift l 20 µV/°C VOUTCMR Output Signal Common Mode Range l 0.5 3.9 V (Note 7) (Voltage Range for the VOCM Pin) RINVOCM Input Resistance, VOCM Pin l 13 19 25 kΩ VOCM Self-Biased Voltage at the VOCM Pin VOCM = Open l 2.35 2.5 2.65 V VOUT Output Voltage, High, +OUT/–OUT Pins IL = 0 l 3.9 4 V IL = –5mA l 3.85 3.95 V Output Voltage, Low, +OUT/–OUT Pins IL = 0 l 0.3 0.45 V IL = 5mA l 0.42 0.54 V ISC Output Short-Circuit Current, +OUT/–OUT Pins l ±40 ±60 mA (Note 10) 6405fb For more information www.linear.com/6405 3
