Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
Note 5:
Supply voltage range is guaranteed by power supply rejection may cause permanent damage to the device. Exposure to any Absolute ratio test. Maximum Rating condition for extended periods may affect device
Note 6:
The input bias current is the average of the average of the currents reliability and lifetime. at the positive and negative input pins.
Note 2:
The inputs are protected by back-to-back diodes. If any of
Note 7:
Matching parameters are the difference between the two amplifiers the input or shutdown pins goes 300mV beyond either supply or the on the LTC6253-7. differential input voltage exceeds 1.4V the input current should be limited
Note 8:
Thermal resistance varies with the amount of PC board metal to less than 10mA. This parameter is guaranteed to meet specified connected to the package. The specified values are with short traces performance through design and/or characterization. It is not production connected to the leads with minimal metal area. tested.
Note 9:
The output voltage is varied from 0.5V to 4.5V during
Note 3:
A heat sink may be required to keep the junction temperature measurement. below the absolute maximum rating when the output current is high. This parameter is guaranteed to meet specified performance through design
Note 10:
Middle 2/3 of the output waveform is observed. RL = 1k to half and/or characterization. It is not production tested. supply.
Note 4:
The LTC6253-7I is guaranteed to meet specified performance
Note 11:
The output voltage is varied from 0.5V to 2.2V during from –40°C to 85°C. The LTC6253-7H is guaranteed to meet specified measurement. performance from –40°C to 125°C.
Note 12:
FPBW is determined from distortion performance in a gain of +7 configuration with HD2, HD3 < –40dBc as the criteria for a valid output.
