VS = 5V, AGND = 2.5V, Gain = 1 (Digital Inputs 001), RL = 10k to midsupply point, unless otherwise noted. ELECTRICAL CHARACTERISTICS Note 1: Absolute Maximum Ratings are those values beyond which the life of the device may be impaired. Note 2: The LTC6911C and LTC6911I are guaranteed functional over the operating temperature range of – 40 °C to 85°C. The LTC6911H is guaranteed functional over the operating temperature range of – 40 °C to 125 °C. Note 3: The LTC6911C is guaranteed to meet specified performance from 0 °C to 70°C. The LTC6911C is designed, characterized and expected to meet specified performance from – 40 °C to 85°C but is not tested or QA sampled at these temperatures. LTC6911I is guaranteed to meet specified performance from – 40 °C to 85°C. The LTC6911H is guaranteed to meet specified performance from –40 °C to 125°C. Note 4: Output voltage swings are measured as differences between the output and the respective supply rail. Note 5: Extended operation with output shorted may cause junction temperature to exceed the 150 °C limit and is not recommended. Note 6: Gain is measured with a DC large-signal test using an output excursion between approximately 30% and 70% of the total supply voltage. Note 7: Channel-to-channel isolation is measured by applying a 200kHz input signal to one channel so that its output varies 1VRMS and measuring the output voltage RMS of the other channel relative to AGND with its input tied to AGND. Isolation is calculated: Isolation V V Isolation V V A OUTB OUTA B OUTA OUTB == 20 20 10 10 • log , • log Note 8: Offset voltage referred to the INA or INB input is (1 + 1/G) times the offset voltage of the internal op amp, where G is the nominal gain magnitude. See Applications Information. Note 9: Input resistance can vary by approximately ±30% part-to-part at a given gain setting (input resistance match remains as specified).
