NOTES
1“Gain Tempco” is for converter only; “Temperature Coefficient” is for bandgap reference only.
2Output propagation delay (tPD) 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.
3RMS 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.
4Intermodulation measured relative to either tone with analog input frequencies of 9.5 MHz and 9.9 MHz at 7 dB below full scale.
5Power 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.
6Measured as the ratio of the change in offset voltage for 5% change in +V D.
Specifications subject to change without notice.

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.
