LTC6416 3.6V ELECTRICAL CHARACTERISTICSThe l denotes the specifi cations which apply over the fulloperating temperature range, otherwise specifi cations are at TA = 25°C. V+ = 3.6V, GND = 0V, No RLOAD, CLOAD = 6pF. VCM = 1.25V,CLHI = V+, CLLO = 0V unless otherwise noted. VINCM is defi ned as (IN+ + IN–)/2. VOUTCM is defi ned as (OUT+ + OUT–)/2. VINDIFF isdefi ned as (IN+ – IN–). VOUTDIFF is defi ned as (OUT+ – OUT–). See DC test circuit schematic.SYMBOLPARAMETERCONDITIONSMINTYPMAXUNITS IVRMIN Input Voltage Range, IN+, IN– Defi ned by Output Voltage Swing Test l 0.1 V (Minimum) (Single-Ended) IVRMAX Input Voltage Range IN+, IN– Defi ned by Output Voltage Swing Test l 2.4 V (Maximum) (Single-Ended) IB Input Bias Current, IN+, IN– IN+ = IN– = 1.25V l –15 –5 15 μA RINDIFF Differential Input Resistance VINDIFF = ±1.2V l 9 12 15 kΩ CINDIFF Differential Input Capacitance 1 pF RINCM Input Common Mode Resistance IN+ = IN– = 0.65V to 1.85V 6 kΩ CMRR Common Mode Rejection Ratio IN+ = IN– = 0.65V to 1.85V, 63.5 83 dB CMRR = (VOUTDIFF/GDIFF/1.2V) l 59.6 dB eN Input Noise Voltage Density f = 100kHz 1.8 nV/√Hz iN Input Noise Current Density f = 100kHz 6.5 pA/√Hz Output Common Mode Voltage Control GCM VCM Pin Common Mode Gain VCM = 0.65V to 1.85V l 0.9 0.96 1.05 V/V VINCMDEFAULT Default Input Common Mode Voltage VINCM.
