Note 2: These parameters are guaranteed and 100% production tested. Note 3: These parameters will be guaranteed but not 100% production tested. Note 4: The LM9044 has been designed to common-mode to b3V, but production testing is only performed at g1V. Note 5: Gain error is given as a percent of full-scale. Full-scale is defined as 1V at the input and 4.5V at the output. Note 6: For operation in ambient temperatures above 25 §C the device must be derated based on a maximum junction temperature of 150 §C and a thermal resistance of 93 §C/W junction to ambient.
