DESCRIPTION
: It features a low-power shutdown mode, which is achieved by driving the SHUTDOWN pin with logic low. The AP4890B contains circuitry to prevent from “pop and click” noise that would otherwise occur during turn-on and turn-off transitions.For maximum flexibility, the AP4890B provides an externally controlled gain (with resistors), as well as an externally controlled turn-on and turn-off times (with the bypass capacitor). 2. FEATURE : 2.5-5.2V operation 65dB PSRR at 217Hz, VDD=5V 0.1µA ultra low current shutdown mode Improved pop & click circuitry No output coupling capacitors, snubber networks or bootstrap capacitors required Thermal shutdown protection External gain configuration capability RoHS compliant and 100% lead(Pb)-free APPLICATIONS
