ELECTRICAL CHARACTERISTICS
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: The inputs are protected by back-to-back diodes. If any of
the input or shutdown pins goes 300mV beyond either supply or the
differential input voltage exceeds 1.4V the input current should be limited
to less than 10mA. This parameter is guaranteed to meet specified
performance through design and/or characterization. It is not production
tested.
Note 3: A heat sink may be required to keep the junction temperature
below the absolute maximum rating when the output current is high. This
parameter is guaranteed to meet specified performance through design
and/or characterization. It is not production tested.
Note 4: The LTC6252C/LTC6253C/LTC6254C and LTC6252I/LTC6253I/
LTC6254I are guaranteed functional over the temperature range of –40°C
to 85°C. The LTC6252H/LTC6253H/LTC6254H are guaranteed functional
over the temperature range of –40°C to 125°C.
Note 5: The LTC6252C/LTC6253C/LTC6254C are guaranteed to meet
specified performance from 0°C to 70°C. The LTC6252C/LTC6253C/
LTC6254C are designed, characterized and expected to meet specified
performance from –40°C to 85°C but are not tested or QA sampled at
these temperatures. The LTC6252I/LTC6253I/LTC6254I are guaranteed
to meet specified performance from –40°C to 85°C. The LTC6252H/
LTC6253H/LTC6254H are guaranteed to meet specified performance from
–40°C to 125°C.
Note 6: Supply voltage range is guaranteed by power supply rejection ratio
test.
Note 7: The input bias current is the average of the average of the currents
at the positive and negative input pins.
Note 8: Matching parameters are the difference between amplifiers A and
D and between B and C on the LTC6254; between the two amplifiers on the
LTC6253.
Note 9: Thermal resistance varies with the amount of PC board metal
connected to the package. The specified values are with short traces
connected to the leads with minimal metal area.
Note 10: The output voltage is varied from 0.5V to 4.5V during
measurement.
Note 11: Middle 2/3 of the output waveform is observed. RL = 1k to half
supply.
Note 12: The output voltage is varied from 0.5V to 2.2V during
measurement.
Note 13: FPBW is determined from distortion performance in a gain of +2
configuration with HD2, HD3 < –40dBc as the criteria for a valid output.
Note 14: Differential gain and phase are measured using a Tektronix
TSG120YC/NTSC signal generator and a Tektronix 1780R video
measurement set.
