MAX1190 Datasheet, PDF (3/21 Pages) Maxim Integrated Products – Dual 10-Bit, 120Msps, 3.3V, Low-Power ADC with Internal Reference and Parallel Outputs

Dual 10-Bit, 120Msps, 3.3V, Low-Power ADC
with Internal Reference and Parallel Outputs
ELECTRICAL CHARACTERISTICS (continued)
(V_DD = 3.3V; OV_DD = 2V; 0.1µF and 1.0µF capacitors from REFP, REFN, and COM to GND, REFOUT connected to REFIN through a
10kΩ resistor; V_REFIN = 2.048V; V_IN = 2V_P-P (differential with respect to COM); C_L = 10pF at digital outputs; f_CLK = 120MHz; 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.)
