5.5 Electrical Characteristics (continued)

at AVDD_5V = 4.75V to 5.25V for ADS9129, and ADS9128, and AVDD_5V = 4.5V to 5.5V for ADS9127, VDD_1V8 = 1.75V

to 1.85V, internal VREF = 4.096V, and maximum throughput (unless otherwise noted); minimum and maximum values at TA =

–40°C to +125°C; typical values at TA = 25°C
