3Vrms Output Voltage into 2.5kΩ Load with 5V Supply Voltage
Differential Input
The TMI8320C is a 3Vrms pop/click-free stereo line driver designed to allow the removal of the output DC-blocking capacitors for reduced component count and cost. The device is ideal for single supply electronics when size and cost are critical design parameters.
The TMI8320C is capable of driving 3Vrms into a 2.5kΩ load with 5V supply voltage. The device has differential inputs and uses external gain setting resistors that supports a gain range of ±1V/V to ±10V/V. The TMI8320C has built-in shutdown control for pop/click-free on/off control.
Using the TMI8320C in audio products can reduce component count compared to traditional methods of generating a 3Vrms output. The TMI8320C doesn’t require a power supply greater than 5V to generate an 8.5VPP output, nor does the device require a split rail power supply. The TMI8320C integrates a charge pump to generate a negative supply rail that provides a clean, pop/click-free ground-biased 3Vrms output.
The TMI8320C is available in Green MSOP10 package. It operates over an ambient temperature range of -40°C to 85°C.
