Description
The MAX9890 provides click-and-pop suppression for devices such as CODECs with test integrated headphone amplifiers that lack a clickless/popless startup/power-up or shutdown/power-down.
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 0.6m.
