MAX1184 Datasheet, PDF (3/21 Pages) Maxim Integrated Products – Dual 10-Bit, 20Msps, +3V, Low-Power ADC with Internal Reference and Parallel Outputs

Dual 10-Bit, 20Msps, +3V, Low-Power ADC with
Internal Reference and Parallel Outputs
ELECTRICAL CHARACTERISTICS (continued)
(V_DD = +3V, OV_DD = +2.5V, 0.1µF and 1.0µF capacitors from REFP, REFN, and COM to GND; REFOUT connected to REFIN through
a 10kΩ resistor, V_IN = 2Vp-p (differential w.r.t. COM), C_L = 10pF at digital outputs (Note 5), f_CLK = 20MHz, T_A = T_MIN to T_MAX, unless
otherwise noted. Typical values are at T_A = +25°C.)
