ELECTRICAL CHARACTERISTICS The q denotes the specifications that apply over the full operating
temperature range, otherwise specifications are at TA = 25°C. VS = 5V, AGND = 2.5V, Gain = 1 (Digital Inputs 001), RL = 10k
to midsupply point, unless otherwise noted.
Note 1: Absolute Maximum Ratings are those values beyond which the life
of the device may be impaired.
Note 2: The LTC6910-XC and LTC6910-XI are guaranteed functional over
the operating temperature range of – 40
°C to 85°C. The LTC6910-XH are
guaranteed functional over the operating temperature range of –40
°C to
125
°C.
Note 3: The LTC6910-XC are guaranteed to meet specified performance
from 0
°C to 70°C. The LTC6910-XC are designed, characterized and
expected to meet specified performance from – 40
°C to 85°C but are not
tested or QA sampled at these temperatures. LTC6910-XI are guaranteed
to meet specified performance from – 40
°C to 85°C. The LTC6910-XH are
guaranteed to meet specified performance from – 40
°C to 125°C.
Note 4: Operating all three logic inputs at 0.5V causes the supply current
to increase typically 0.1mA from this specification.
Note 5: Output voltage swings are measured as differences between the
output and the respective supply rail.
Note 6: Extended operation with output shorted may cause junction
temperature to exceed the 150
°C limit and is not recommended.
Note 7: Gain is measured with a DC large-signal test using an output
excursion between approximately 30% and 70% of supply voltage.
Note 8: Offset voltage referred to “IN” pin is (1 + 1/G) times offset voltage
of the internal op amp, where G is nominal gain magnitude. See Applica-
tions Information.
Note 9: Input resistance can vary by approximately
±30% part-to-part at a
given gain setting.
Note 10: At limits of AGND input range, open-loop gain of internal op amp
may be greater than, or as much as 15dB below, its value at nominal
AGND value.
