NOTES
1Gain error and gain temperature coefficient are based on the ADC only (with a fixed 2.5 V external reference).
23 dB bandwidth with full-power input signal.
3t
V and tPD are measured from the threshold crossing of the ENCODE input to valid TTL levels of the digital outputs. The output ac load during test is 5 pF (Refer to
equivalent circuits Figures 5 and 6).
4I
IH and IIL are valid for differential input voltages of less than 1.5 V. At higher differential voltages, the input current will increase to a maximum of 1.5 mA.
5Power dissipation is measured under the following conditions: analog input is –1 dBFS at 19.7 MHz.
