MAX1425_11 Datasheet, PDF (8/16 Pages) Maxim Integrated Products – 10-Bit, 20Msps ADC Separate Digital Supply Input for 3V Logic Compatibility

10-Bit, 20Msps ADC
Typical Operating Characteristics (continued)
(V_AVDD = V_CMLP = +5V, V_DVDD = +3.3V, V_CMLN = V_AGND = 0V, internal reference, digital output load = 35pF, f_CLK = 20Msps (50%
duty cycle), for dynamic performance 0dB is full scale, T_A = +25°C, unless otherwise noted.)
