DC ELECTRICAL CHARACTERISTICS

Temperature ranges = -55 to +225

°C, VDD = 10.0V ±10%

Typical @ +25

°C, Vlogic = +5V, unless otherwise specified

(1) Can be adjusted by tying VTRIM to external resistor and VREF_OUT or VSSA.

(2) Available for external loads, external load should not change during conversion.
