LT1635

ELECTRICAL CHARACTERISTICS

±5V OP AMP: The q denotes the specifications which apply over the full operating temperature range, otherwise specifications are

at TA = 25°C. VS = ±5V; VCM = VOUT = 0V, unless otherwise noted. (Note 2)

Note 1: Absolute Maximum Ratings are those values beyond which the life

of a device may be imparied.

Note 2: The LT1635C is guaranteed to operate over the commercial

temperature range of 0°C to 70°C. It is designed, characterized and

expected to meet these extended temperature limits, but is not tested at

– 40°C and 85°C. The LT1635I is guaranteed to meet the industrial

temperature range.

Note 3: The LT1635 op amp operates on a 1.2V supply over the full

industrial temperature range with an input common mode voltage of 0V to

0.2V. The minimum supply voltage for the reference to operate properly

over this temperature range is 1.3V.

Note 4: This parameter is not 100% tested. Temperature coefficient is

measured by dividing the change in output voltage by specified

temperature range.

Note 5: Shunt gain defines the operation in floating applications when the

output is connected to the V + terminal and input common mode is

referred to V –.

Note 6: If part is stored outside of the specified temperature range, the

output may shift due to hysteresis.
