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.)

Note 1: Internal reference, REFIN bypassed to AGND with a combination of 0.22µF in parallel with 1nF capacitor.

Note 2: External 2.048V reference applied to REFIN.

Note 3: Internal reference disabled. VREFIN = 0, VREFP = 2.162V, VCML = 1.65V, and VREFN = 1.138V.

Note 4: IMD is measured with respect to either of the fundamental tones.

Note 5: Specifies the common-mode range of the differential input signal supplied to the MAX1420.

Note 6: VDIFF = VREFP - VREFN.

Note 7: Input bandwidth is measured at a -3dB level.

Note 8: VREFIN is internally biased to 2.048V through a 10kΩ resistor.

Note 9: Measured as the ratio of the change in mid-scale offset voltage for a ±5% change in VAVDD, using the internal reference.

Typical Operating Characteristics

(VAVDD = VDVDD = 3.3V, AGND = DGND = 0, VIN = ±1.024V, differential input drive, AIN = -0.5dBFS, fCLK = 60.006MHz (50% duty

cycle), digital output load CL = 10pF, TA = TMIN to TMAX, unless otherwise noted. Typical values are at TA = +25°C.)
