LTC1595/LTC1596/LTC1596-1
ELECTRICAL CHARACTERISTICS The l denotes the specifications which apply over the full operating
temperature range, otherwise specifications are at TA = 25°C. VDD = 5V ±10%, VREF = 10V, VOUT1 = GND = 0V, TA = TMIN to TMAX,
unless otherwise noted.

Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2: ±1LSB = ±0.0015% of full-scale = ±15.3ppm of full-scale.
Note 3: Using internal feedback resistor.
Note 4: Guaranteed by design, not subject to test.
Note 5: IOUT1 with DAC register loaded with all 0s.
Note 6: Typical temperature coefficient is 100ppm/°C.
Note 7: OUT1 load = 100Ω in parallel with 13pF.
Note 8: To 0.0015% for a full-scale change, measured from the falling
edge of LD1, LD2 or LD.
Note 9: VREF = 6VRMS at 1kHz. DAC register loaded with all 1s;
op amp = LT1007.
Note 10: Calculation from en = √4kTRB where: k = Boltzmann constant
(J/°K); R = resistance (Ω); T = temperature (°K); B = bandwidth (Hz).
Note 11: Minimum high time for STB1, STB2, STB4. Minimum low time
for STB3.
Note 12: Minimum low time for STB1, STB2, STB4. Minimum high time
for STB3.
