MAX104 Datasheet, PDF (6/32 Pages) Maxim Integrated Products – ±5V, 1Gsps, 8-Bit ADC with On-Chip 2.2GHz Track/Hold Amplifier

±5V, 1Gsps, 8-Bit ADC with
On-Chip 2.2GHz Track/Hold Amplifier
Note 11: Effective Number of Bits (ENOB) and Signal-to-Noise Plus Distortion (SINAD) are computed from a curve fit referenced to
the theoretical full-scale range.
Note 12: Total Harmonic Distortion (THD) is computed from the first five harmonics.
Note 13: Guaranteed by design with a reset pulse one clock period long or greater.
Note 14: The DREADY to DATA propagation delay is measured from the 50% point on the rising edge of the DREADY signal (when
the output data changes) to the 50% point on a data output bit. This places the falling edge of the DREADY signal in the
middle of the data output valid window, within the differences between the DREADY and DATA rise and fall times, which
gives maximum setup and hold time for latching external data latches.
Typical Operating Characteristics
(V_CCA = V_CCI = V_CCD = +5V, V_EE = -5V, V_CCO = +3.3V, REFIN connected to REFOUT, f_S = 1Gsps, T_A = +25°C, unless otherwise
noted.)
