“Gain T empco” is for converter only; “T emperature Coefficient” is for bandgap reference only.
2
Output propagation delay (t
PD
) is measured from the 50% point of the rising edge of the encode command to the midpoint of the digital outputs with 10 pF maximum
loads.
3
RMS signal to rms noise with analog input signal 0.5 dB below full scale at specified frequency for BR/BRS, 1.0 dB below full scale for BRS-60.
4
Intermodulation measured relative to either tone with analog input frequencies of 9.5 MHz and 9.9 MHz at 7 dB below full scale.
5
Power dissipation is measured at full update rate with AIN of 10.3 MHz and digital outputs loaded with 10 pF maximum. See Figure 4 for power dissipation at other
conditions.
6
Measured as the ratio of the change in offset voltage for 5% change in +V

device at these or any other conditions above those indicated in the operational
sections of this specification is not implied. Exposure to absolute maximum ratings
for extended periods may effect device reliability.
