LTC7541A
VDD = 15V, VREF = 10V, OUT 1 = OUT 2 = GND = 0V, TA = TMIN to TMAX, unless otherwise specified.
The q denotes specifications which apply over the full operating
temperature range.
Note 1:
±0.5LSB = ±0.012% of full scale.
Note 2: Using internal feedback resistor.
Note 3: Guaranteed by design, not subject to test.
Note 4: IOUT1 with all digital inputs = 0V or IOUT2 with all digital
inputs = VDD.
Note 5: OUT 1 load = 100
in parallel with 13pF.
Note 6: Measured from digital input change to 90% of final analog value.
Digital inputs = 0V to VDD or VDD to 0V.
Note 7: VREF = 0V. All digital inputs 0V to VDD or VDD to 0V. Measured
using LT1363 as output amplifier.
