TIMING 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, TA = TMAX to
TMIN. Timing specifications apply with a 32 pF load, 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.
