... and a voltage noise density of 55 nV/√ kHz. The ADA4505-2 was designed to solve two key problems in low voltage battery-powered applications: battery voltage decrease over time and rail-to-rail input stage distortion. In battery-powered applications, the supply voltage available to the IC is the voltage of the battery ...

... CMRR minimum, an input-referred error of 790 μV is introduced. Another part with a CMRR minimum generates a 6.3 mV error. The ADA4505-2 CMRR minimum causes only a 79 μV error. As with the PSRR error, there are complex ways to minimize this error, but the ADA4505-2 solves this problem without incurring unnecessary circuitry complexity or increased cost ...

... Butterworth. Low power op amps with bandwidths of 50 kHz to 500 kHz should be adequate. The ADA4505-2 with its 50 kHz GBP and 10 μA typical of current consumption meets these requirements. A circuit design of a four-pole Butterworth filter (preceded by a one-pole low-pass filter) is shown in Figure 53. With a 3.3 V battery, the total power consumption of this design is 198 μ ...
