SPECIFICATIONS
VDD = 12 V to 16.5 V, VSS = −12 V to −16.5 V, VCC = 4.75 V to 5.25 V, VDRIVE = 2.7 V to 5.25 V, VREF = 2.5 V internal/external, fSCLK = 20 MHz,
fS = 1 MSPS, TA = TMAX to TMIN, unless otherwise noted. MUXOUT+ is connected directly to ADCIN+ and MUXOUT− is connected directly to
ADCIN−, which is connected to GND for single-ended mode.
