LTC6373
ELECTRICAL CHARACTERISTICS Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
Note 8:
Input bias current is defined as the maximum of the input currents may cause permanent damage to the device. Exposure to any Absolute flowing into either of the input pins (–IN and +IN). Input Offset current is Maximum Rating condition for extended periods may affect device defined as the difference between the input currents (I + – OS = IB – IB ). reliability and lifetime.
Note 9:
Input CMRR (CMRR) is defined as the ratio of the change in
Note 2:
The LTC6373 is capable of producing peak output currents in the input common mode voltage at the pins +IN or –IN to the change excess of 40mA. Current density limitations within the IC require the in differential input referred offset voltage. Output CMRR (CMRRIO) is continuous RMS current supplied by the output (sourcing or sinking) defined as the ratio of the change in the voltage at the VOCM pin to the over the operating lifetime of the part be limited to under 40mA (Absolute change in differential input referred offset voltage. Maximum).
Note 10:
Differential power supply rejection ratio (PSRR) is defined as
Note 3:
A heat sink may be required to keep the junction temperature the ratio of the change in supply voltage to the change in differential below absolute maximum when the output is shorted indefinitely. input referred offset voltage. Common mode power supply rejection ratio
Note 4:
The LTC6373I is guaranteed functional over the operating (PSRRCM) is defined as the ratio of the change in supply voltage to the temperature range of –40°C to 85°C. The LTC6373H is guaranteed change in the common mode offset voltage. functional over the operating temperature range of –40°C to 125°C.
Note 11:
This parameter is measured in a high speed automatic tester
Note 5:
The LTC6373I is guaranteed to meet specified performance that does not measure the thermal effects with longer time constants. The from –40°C to 85°C. The LTC6373H is guaranteed to meet specified magnitude of these thermal effects are dependent on the package used, performance from –40°C to 125°C. PCB layout, heat sinking and air flow conditions.
Note 6:
Guaranteed by design.
Note 12:
Hysteresis in output voltage is created by mechanical stress
Note 7:
ESD (Electrostatic Discharge) sensitive device. ESD protection that differs depending on whether the IC was previously at a higher or devices are used extensively internal to the LTC6373; however, high lower temperature. Output voltage is always measured at 25°C, but electrostatic discharge can damage or degrade the device. Use proper ESD the IC is cycled to the hot or cold temperature limit before successive handling precautions. measurements. For instruments that are stored in well controlled temperatures (within 20 or 30 degrees of operational temperature), hysteresis is usually not a significant error source. Typical Hysteresis is the worst case of differential offset measured between 25°C to -40°C to 25°C thermal cycle and 25°C to 125°C to 25°C thermal cycle.
