Capless 3Vrms Line Driver with 8MHz 5th-Order Video Driver
Capless 3Vrms Line Driver with 8MHz 5th-Order Video Driver

The SGM89111 is a 3Vrms 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 SGM89111 also has a single rail-to-rail 5th-order video filter with a slew rate of 35V/μs and a -3dB bandwidth of 8MHz. It can operate from 3.0V to 5.5V power supply.

The SGM89111 has differential inputs and is capable of driving 3Vrms into a 2.5kΩ load with 5V 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. The video driver of the SGM89111 uses an internal level shift circuit to allow DC-coupled output and avoid synchronous pulse clipping.

SGM89111 does not require a power supply. An integrated charge pump generates a 3Vrms output negative power rail that provides a clean, pop/click-free ground offset.

The SGM89111 is available in a Green TSSOP-20 package. It operates over an ambient temperature range of -40 to +85.
