安富利:
The MAX9890 provides click-and-pop suppression for devices such as CODECs with integrated headphone amplifiers that lack a clickless/popless startup/power-up or shutdown/power-down. The device controls the ramping of the DC bias voltage on the output-coupling capacitors and the application of the audio signal to ensure that no audible transients are present at the headphones. The MAX9890A features a 200ms startup time for use with up to 100µF coupling capacitors. The MAX9890B features a 330ms startup time for use with greater than 100µF coupling capacitors.The MAX9890 consumes 14µA of supply current and 0.001µA in shutdown, while contributing less than 0.003% THD+N into a 32Ω load. ESD Human Body Model protection circuitry on the outputs protect the MAX9890 and devices further up the signal chain from ESD strikes up to ±8kV.The MAX9890 is available in a miniature 1.5mm x 1.5mm x 0.6mm 9-bump chip-scale package UCSP™, as well as an 8-pin TDFN package 3mm x 3mm x 0.8mm, and is specified for operation over the-40°C to +85°C extended temperature range.
