LTC1588/LTC1589/LTC1592

1588992fa

Note 1: Absolute Maximum Ratings are those values beyond which the life

of a device may be impaired.

Note 2:

±1LSB = ±0.0015% of full scale = ±15.3ppm of full scale

(LTC1592).

±1LSB = ±0.006% of full scale = ±61.2ppm of full scale

(LTC1589).

±1LSB = 0.024% of full scale = ±244.8ppm of full scale

(LTC1588).

Note 3: Using internal feedback resistor.

Note 4: Guaranteed by design, not subject to test.

Note 6: Typical temperature coefficient is 100ppm/

°C.

Note 7: To 0.0015% for a full-scale change, measured from the falling

edge of LD for the LTC1592 only.

amplifier = LT1468.

Note 10: Midscale transition code: 32767 to 32768 for the LTC1592, 8191

to 8192 for the LTC1589, 2047 to 2048 for the LTC1588.

Note 12: If a continuous clock is used with data changing on the rising

frequency. If data changes on the falling edge of SCK then the setup time

will limit the maximum clock frequency to 8MHz (continuous 50% duty

cycle clock).
