ELECTRICAL CHARACTERISTICS 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. VOCM is the voltage on the VOCM pin. VOUTCM is defined as (+VOUT + –VOUT)/2. VINCM is defined as (+VIN + –VIN)/2. VINDIFF is
defined as (+VIN – –VIN). VOUTDIFF is defined as (+VOUT – –VOUT). Typical values are at TA = 25°C. Specifications apply to the
LTC1992-5 only.

Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2: Output load is connected to the midpoint of the +VS and –VS
potentials. Measurement is taken single-ended, one output loaded at a
time.
Note 3: A heat sink may be required to keep the junction temperature
below the absolute maximum when the output is shorted indefinitely.
Note 4: Differential output slew rate. Slew rate is measured single ended
and doubled to get the listed numbers.
Note 5: The LTC1992C/LTC1992-XC/LTC1992I/LTC1992-XI are guaranteed
functional over an operating temperature of –40°C to 85°C. The
LTC1992H/LTC1992-XH are guaranteed functional over the extended
operating temperature of –40°C to 125°C.
Note 6: The LTC1992C/LTC1992-XC are guaranteed to meet the specified
performance limits over the 0°C to 70°C temperature range and are
designed, characterized and expected to meet the specified performance
limits over the –40°C to 85°C temperature range but are not tested or QA
sampled at these temperatures. The LTC1992I/LTC1992-XI are guaranteed
to meet the specified performance limits over the –40°C to 85°C
temperature range. The LTC1992H/LTC1992-XH are guaranteed to meet the
specified performance limits over the –40°C to 125°C temperature range.
Note 7: Differential offset voltage, differential offset voltage drift, CMRR,
noise voltage density and PSRR are referred to the internal amplifier’s
input to allow for direct comparison of gain blocks with discrete amplifiers.
