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 = ±0.006% of full scale = ±61ppm of full scale for the
LTC1591/LTC1591-1.
±1LSB = ±0.0015% of full scale = ±15.3ppm of full
scale for the LTC1597/LTC1597-1.
Note 3: Using internal feedback resistor.
Note 4: Guaranteed by design, not subject to test.
Note 5: I(OUT1) with DAC register loaded to all 0s.
Note 6: Typical temperature coefficient is 100ppm/
°C.
Note 7: IOUT1 load = 100Ω in parallel with 13pF.
Note 8: To 0.006% for a full-scale change, measured from the rising edge
of LD for the LTC1591/LTC1591-1. To 0.0015% for a full-scale change,
measured from the rising edge of LD for the LTC1597/LTC1597-1.
Note 9: VREF = 0V. DAC register contents changed from all 0s to all 1s or
all 1s to all 0s.
Note 10: VREF = 6VRMS at 1kHz. DAC register loaded with all 1s.
Note 11: Calculation from en = √4kTRB where: k = Boltzmann constant
(J/
°K), R = resistance (Ω), T = temperature (°K), B = bandwidth (Hz).
Note 12: Midscale transition code: 01 1111 1111 1111 to 10 0000 0000
0000 for the LTC1591/LTC1591-1 and 0111 1111 1111 1111 to 1000
0000 0000 0000 for the LTC1597/LTC1597-1.
Note 13: R1 and R2 are measured between R1 and RCOM, REF and RCOM.
Note 14: Measured using the LT1468 op amp in unipolar mode for I/V
converter and LT1468 I/V and LT1001 reference inverter in bipolar mode.
Sample Rate = 50kHz, Signal Frequency = 1kHz, VREF = 5V, TA = 25°C.
The
● denotes specifications that apply over the full operating temperature
range. VCC = 5V ±10%, VREF = 10V, IOUT1 = AGND = DGND = 0V, TA = TMIN to TMAX, unless otherwise noted.
