MAX1448 Datasheet, PDF (3/21 Pages) Maxim Integrated Products – 10-Bit, 80Msps, Single 3.0V, Low-Power ADC with Internal Reference

10-Bit, 80Msps, Single 3.0V, Low-Power
ADC with Internal Reference
ELECTRICAL CHARACTERISTICS (continued)
(V_DD = 3.0V, OV_DD = 2V, 0.1µF and 1µF capacitors from REFP, REFN, and COM to GND, V_REFIN = 2.048V, REFOUT connected to
REFIN through a 10kΩ resistor, V_IN = 2V_P-P (differential with respect to COM), C_L = 10pF at digital outputs, f_CLK = 83.3MHz, T_A = T_MIN
to T_MAX, unless otherwise noted. ≥ +25°C guaranteed by production test, < +25°C guaranteed by design and characterization; typical
values are at T_A = +25°C.)
