(1)

8 averages, 1-Hz conversion cycle. Measurements are taken in oil bath.

(2)

±0.75°C maximum error between –55°C to –40°C.

(3)

Repeatability is the ability to reproduce a reading when the measured temperature is applied consecutively, under the same conditions.

(4)

Long-term stability is determined using accelerated operational life testing at a junction temperature of 150°C.

(5)

Hysteresis is defined as the ability to reproduce a temperature reading as the temperature varies from room

→ hot → room → cold →

room. The temperatures used for this test are –40°C, 25°C, and 125°C.

(6)

Quiescent current between conversions.

6.5 Electrical Characteristics

minimum and maximum specifications are over –55°C to +125°C and V+ = 1.9 V to 5.5 V (unless otherwise noted); typical

specifications are at TA = 25°C and V+ = 3.3 V
