Datasheet LTC6800 (Analog Devices) - 4

LTC6800 elecTrical characTerisTics
Note 3:
If the total source resistance is less than 10k, no DC errors result
Note 6:
The power supply rejection ratio (PSRR) measurement accuracy from the input bias currents or the mismatch of the input bias currents or depends on the proximity of the power supply bypass capacitor to the the mismatch of the resistances connected to –IN and +IN. device under test. Because of this, the PSRR is 100% tested to relaxed
Note 4:
The CMRR with a voltage gain, A limits at final test. However, their values are guaranteed by design to meet V, larger than 10 is 120dB (typ).
Note 5:
At temperatures above 70°C, the common mode rejection ratio the data sheet limits. lowers when the common mode input voltage is within 100mV of the
Note 7:
The LTC6800H is guaranteed functional over the operating supply rails. temperature range of –40°C to 125°C. Specifications over the –40°C to 125°C range (denoted by l) are assured by design and characterization but are not tested or QA sampled at these temperatures. Typical perForMance characTerisTics
