3 All AC specifications expressed in decibels are referred to full-scale input range (FSR) and are tested with an input signal of 0.5 dB below full scale, unless otherwise

specified.

4 Hysteresis in output voltage is created by package stress that differs depending on whether the IC is previously at a higher or lower temperature. Output voltage is always

measured at 25°C, but the IC is cycled to the hot or cold temperature limit before successive measurements. Hysteresis measures the maximum output change for the

averages of three hot or cold temperature cycles. For instruments that are stored at well controlled temperatures (within 20°C or 30°C degrees of operational temperature),

it is usually not a dominant error source. Typical hysteresis is the worst-case of 25°C to cold to 25°C or 25°C to hot to 25°C, preconditioned by one thermal cycle.

5 Maximum operating supply voltage, VS (VS+ − VS−) should not exceed 10 V.

6 The ADAQ4381-4 is rated for performance over extended industrial temperature range, TCASE = −40°C to +105°C.
