MAX1196 Datasheet, PDF (3/23 Pages) Maxim Integrated Products – Dual 8-Bit, 40Msps, 3V, Low-Power ADC with Internal Reference and Multiplexed Parallel Outputs

Dual 8-Bit, 40Msps, 3V, Low-Power ADC with
Internal Reference and Multiplexed Parallel Outputs
ELECTRICAL CHARACTERISTICS (continued)
(V_DD = OV_DD = 3V, 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 (Note 5), f_CLK = 40MHz, 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.)
