The LM48100Q-Q1 has output fault detection and I2C volume control.\u003c\/p\u003e \u003cp\u003eThe StereoAmp Click features a 3.5mm input jack and four output screw terminals for connecting passive speakers. It runs on either 3.3V or 5V power supply and communicates with the MCU through the I2C interface.\u003c\/p\u003e \u003cp\u003eEach LM48100Q-Q1 is used for one channel, left or right. Both input paths have their own independent, 32-step volume control.\u003c\/p\u003e \u003cp\u003eThe mixer, volume control and device mode select are controlled through an I2C compatible interface.\u003c\/p\u003e \u003cp\u003eBTL or a bridge-tied load is an output configuration where the speakers are connected (bridged) between two audio amplifier outputs. In a single-ended configuration one side of the load is connected to the ground. Here both channels are connected, but one has an inverted signal. Compared to a single-ended configuration BTL has two times more voltage swing across the load (speakers).\u003c\/p\u003e \u003cp\u003eThe doubled voltage swing means four times more power to the speakers. This is ideal for applications and devices where due to battery size the supply voltage is lower.\u003c\/p\u003e \u003cp\u003eThe IC has an I2C selectable low power shutdown mode that disables the device, reducing current consumption to 0.01�¼A.\u003c\/p\u003e \u003cp\u003eThe output fault detection system can sense load conditions and protect the device during short circuit events and detect open circuit conditions. The LM48100Q-Q1 output fault diagnostics are controlled through the I2C interface.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003eInterface: GPIO, I\u003csup\u003e2\u003c\/sup\u003eC\u003c\/li\u003e \u003cli\u003eCompatibility: mikroBUSâ�¢\u003c\/li\u003e \u003cli\u003eDimensions: 42.9 x 25.4mm\u003c\/li\u003e \u003cli\u003eInput Voltage: 3.3V or 5V\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003e\u003cstrong\u003eDocuments:\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003e\u003ca href=\"https:\/\/cdn.sparkfun.com\/assets\/8\/7\/3\/0\/1\/Schematic-18869-StereoAmp_Click.pdf\"\u003eSchematic\u003c\/a\u003e\u003c\/li\u003e \u003cli\u003e\u003ca href=\"https:\/\/github.com\/MikroElektronika\/mikrosdk_click_v2\/tree\/master\/clicks\/stereoamp\"\u003eGitHub\u003c\/a\u003e\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003e\u003cstrong\u003eVideos\u003c\/strong\u003e\u003c\/p\u003e \u003cdiv class=\"flex-video-wrap clearfix\"\u003e \u003cdiv class=\"flex-video widescreen img\"\u003e \u003ciframe src=\"https:\/\/www.youtube.com\/embed\/zzlh1oGii1Q\/?autohide=1\u0026amp;border=0\u0026amp;wmode=opaque\u0026amp;enablejsapi=1\" frameborder=\"0\" allowfullscreen width=\"560\" height=\"315\"\u003e\u003c\/iframe\u003e \u003c\/div\u003e \u003c\/div\u003e","brand":"sparkfun-10","offers":[{"title":"Default Title","offer_id":40054674522197,"sku":"18869:DEV-18869:spark","price":4150.0,"currency_code":"INR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1034\/1611\/products\/18869_-_StereoAmp_Click.jpg?v=1651340869","url":"https:\/\/www.tanotis.com\/products\/sparkfun-mikroe-stereoamp-click","provider":"Tanotis","version":"1.0","type":"link"}
