... The LTC1069-6 typically consumes 1mA under single 3V supply operation and 1.2mA under 5V operation. The cutoff frequency of the LTC1069-6 is clock tunable and it is (Typ) CUTOFF equal to the clock frequency divided by 50. The input signal is sampled twice per clock cycle to lower the risk of aliasing. The typical passband ripple is ± ...

... Note 3: The input voltage can swing to either rail (V output typically swings 50mV from ground and 0.8V from V Note 4: The LTC1069-6 is optimized for 3V and 5V operation. Although the device can operate with a single 10V supply or ±5V, the total harmonic distortion will be degraded. For single 10V or ±5V supply operation we recommend to use the LTC1069-1 ...
