SWITCHING CHARACTERISTICS
Temperature ranges as follows: J, K, L versions: –40 C to +85 C
Gain error is measured using internal feedback resistor. Full-Scale Range (FSR) = V
Guaranteed not tested.
DAC thin-film resistor temperature coefficient is approximately –300 ppm/ C.
AC parameter, sample tested @ +25 C to ensure conformance to specification.
