... Maximum Rating condition for extended periods may affect device reliability and lifetime. Note 2: All pins are protected by steering diodes to either supply. If any pin is driven beyond the LTC6605-7’s supply voltage, the excess input current (current in excess of what it takes to drive that pin to the supply rail) should be limited to less than 10mA. ...

... Stand- alone op amps often specify noise referred to the inputs of the op amp. The LTC6605-7’s internal op amp has input referred voltage noise of only 2.1nV/√Hz. In addition to the noise gen- erated by the amplifi er, the surrounding feedback resistors also contribute noise. A noise model is shown in Figure 7a. The output spot noise generated by both the amplifi ...
