LT1113
elecTrical characTerisTics Note 7:
Input voltage range functionality is assured by testing offset
Note 11:
∆CMRR and ∆PSRR are defined as follows: voltage at the input voltage range limits to a maximum of 2.3mV (1) CMRR and PSRR are measured in µV/V on the individual amplifiers. (A grade) to 2.8mV (C grade). (2) The difference is calculated between the matching sides in µV/V.
Note 8:
This parameter is not 100% tested. (3) The result is converted to dB.
Note 9:
Slew rate is measured in AV = –1; input signal is ±7.5V, output
Note 12:
The LT1113 is measured in an automated tester in less than one measured at ±2.5V. second after application of power. Depending on the package used, power
Note 10:
The LT1113 is designed, characterized and expected to meet dissipation, heat sinking, and air flow conditions, the fully warmed-up chip these extended temperature limits, but is not tested at –40°C and 85°C. temperature can be 10°C to 50°C higher than the ambient temperature. Guaranteed I grade parts are available. Consult factory.
