LTC1992 Family ELECTRICAL CHARACTERISTICSThe l denotes the specifications which apply over the full operatingtemperature range, otherwise specifications are at TA = 25°C. +VS = 5V, –VS = 0V, VINCM = VOUTCM = VOCM = 2.5V, unless otherwisenoted. VOCM is the voltage on the VOCM pin. VOUTCM is defined as (+VOUT + –VOUT)/2. VINCM is defined as (+VIN + –VIN)/2. VINDIFF isdefined as (+VIN – –VIN). VOUTDIFF is defined as (+VOUT – –VOUT). Typical values are at TA = 25°C. Specifications apply to theLTC1992-1 only.LTC1992-1CMS8LTC1992-1ISM8LTC1992-1HMS8SYMBOL PARAMETERCONDITIONSMINTYPMAXMINTYPMAXUNITS GDIFF Differential Gain 1 1 V/V Differential Gain Error l ±0.1 ±0.3 ±0.1 ±0.35 % Differential Gain Nonlinearity 50 50 ppm Differential Gain Temperature Coefficient l 3.5 3.5 ppm/°C en Input Referred Noise Voltage Density (Note 7) f = 1kHz 45 45 nV/√Hz RIN Input Resistance, Single-Ended +IN, –IN Pins l 22.5 30 37.5 22 30 38 kΩ VINCMR Input Signal Common Mode Range VS = 5V –0.1V to 4.9V –0.1V to 4.9V V CMRR Common Mode Rejection Ratio VINCM = –0.1V to 3.7V l 55 60 55 60 dB (Amplifier Input Referred) (Note 7) SR Slew Rate (Note 4) l 0.5 1.5 0.5 1.5 V/μs GBW Gain-Bandwidth Product fTEST = 180kHz 3 3 MHz The l denotes the specifications which apply over the full operating temperature range, otherwise specifications are at TA = 25°C.+VS = 5V, –VS = 0V, VINCM = VOUTCM = VOCM = 2.5V, unless otherwise noted.
