MAX1420

12-Bit, 60Msps, 3.3V, Low-Power ADC with Internal Reference

Maxim Integrated 

12-Bit, 60Msps, 3.3V, Low-Power ADC

with Internal Reference

ELECTRICAL CHARACTERISTICS (continued)

(VAVDD = VDVDD = 3.3V, AGND = DGND = 0, VIN = ±1.024V, differential input voltage at -0.5dBFS, internal reference, fCLK =

62.5MHz (50% duty cycle); digital output load CL = 10pF, ≥+25°C guaranteed by production test, <+25°C guaranteed by design and

characterization. Typical values are at TA = +25°C.)
