The SGM89000 is a 2Vrms pop/click-free stereo line driver. The device is ideal for single supply applications. Capless design can eliminate output DC-blocking capacitors for less-component count and low-cost.
The SGM89000 has differential inputs and is capable of driving 2Vrms into a 2.5kΩ load with 3.3V supply voltage. Build-in shutdown control also helps for pop/click-free on/off control. The gain can be set by users from ±1V/V to ±10V/V through external gain setting resistors that also allows the implementation of a 2nd-order low pass filter to compliment SOC and DAC's converters.
SGM89000 does not require a power supply. An integrated charge pump generates a 2Vrms output negative power rail that provides a clean, pop/click-free ground offset.
The SGM89000 is available in a Green TSSOP-14 package. It operates over an ambient temperature range of -40℃ to +85℃.
