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.
6Typical thermal impedance for the ST-44 (LQFP) 44-lead package (in still air):

JA = 55

7A change in input offset voltage with respect to a change in V
DD.
8SNR/harmonics based on an analog input voltage of –1.0 dBFS referenced to a 1.024 V full-scale input range.
Specifications subject to change without notice.
