ELECTRICAL CHARACTERISTICS The
l
denotes the specifications which apply over the full operating temperature range, otherwise specifications are at TA = 25°C. V+ = 5V, V– = 0V, VCM = VOCM = VICM = 2.5V, VSHDN = open. VS is defined as (V+ – V–). VOUTCM is defined as (V+OUT + V–OUT)/2. VICM is defined as (V+IN + V–IN)/2. VOUTDIFF is defined as (V+OUT – V–OUT). SYMBOL PARAMETER CONDITIONS MIN TYP MAX UNITS

Note 9:
Input common mode range is tested by verifying that at the limits may cause permanent damage to the device. Exposure to any Absolute stated in the Electrical Characteristics table, the differential offset (VOSDIFF) Maximum Rating condition for extended periods may affect device and common mode offset (VOSCM) have not deviated by more than ±1mV reliability and lifetime. and ±35mV respectively compared to the VICM = 2.5V (at VS = 5V) and

Input pins (+IN, –IN, V V OCM and SHDN) are protected by steering ICM = 1.5V (at VS = 3V) cases. diodes to either supply. If the inputs should exceed either supply voltage, Output common mode range is tested by verifying that at the limits stated the input current should be limited to less than 10mA. In addition, the in the Electrical Characteristics table, the common mode offset (VOSCM) inputs +IN, –IN are protected by a pair of back-to-back diodes. If the has not deviated by more than ±15mV compared to the VOCM = 2.5V differential input voltage exceeds 1.4V, the input current should be limited (at VS = 5V) and VOCM = 1.5V (at VS = 3V) cases. to less than 10mA.

Output CMRR is defined as the ratio of indefinitely. the change in the voltage at the VOCM pin to the change in differential
Note 4:
The LTC6362C and LTC6362I are guaranteed functional over input referred offset voltage. This specification is strongly dependent on the operating temperature range of –40°C to 85°C. The LTC6362H is feedback ratio matching between the two outputs and their respective guaranteed functional over the operating temperature range of –40°C to inputs and it is difficult to measure actual amplifier performance (see 125°C.

Supply voltage range is guaranteed by power supply rejection determined by a large sampling of typical parts. Drift is not guaranteed by ratio test. test or QA sampled at this value.
Note 8:
Input bias current is defined as the maximum of the input currents flowing into either of the input pins (–IN and +IN). Input Offset current is defined as the difference between the input currents (I + – OS = IB – IB ). 6362fa 5 Document Outline Features Applications Description Typical Application Absolute Maximum Ratings Pin Configuration Order Information Electrical Characteristics Typical Performance Characteristics Pin Functions Block Diagram Applications Information Typical Applications Package Description Revision History Typical Application Related Parts
