MAX1198 Datasheet, PDF (3/22 Pages) Maxim Integrated Products – Dual, 8-Bit, 100Msps, 3.3V, Low-Power ADC with Internal Reference and Parallel Outputs

Dual, 8-Bit, 100Msps, 3.3V, Low-Power ADC
with Internal Reference and Parallel Outputs
ELECTRICAL CHARACTERISTICS (continued)
(V_DD = 3.3V, OV_DD = 2.5V, 0.1µF and 2.2µF capacitors from REFP, REFN, and COM to GND; 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 = 100MHz, 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.)
