The board operates on a dual power supply and includes an onboard fault indicator LED for easy diagnostics, with header connectors for power input, signal input, and output that make integration into a larger design simple. Figure 1 shows the assembled board.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eThe LT1970A is a ±500 mA power op amp with precise, externally controlled current limiting. Separate control voltages program the sourcing and sinking current-limit thresholds to 1% accuracy, and output current can be boosted further by adding external power transistors.\u003c\/p\u003e\n\u003cp\u003eThe device operates from single or split supplies from 5 V to 36 V total supply voltage. In normal operation, the input-stage and output-stage supplies are tied together (VCC to V+ and VEE to V−). The output stage can also be powered from independent, lower-voltage rails to reduce power dissipation.\u003c\/p\u003e\n\u003cp\u003eThe amplifier is unity-gain stable with a 3.6 MHz gain-bandwidth product, slews at 1.6 V\/µs, and can drive capacitive and inductive loads directly.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eSpecs and Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePower supply: ±18 V (dual supply)\u003c\/li\u003e\n\u003cli\u003eMinimum output current: ±500 mA\u003c\/li\u003e\n\u003cli\u003eKey IC: LT1970A power operational amplifier\u003c\/li\u003e\n\u003cli\u003eIndependent adjustment of source and sink current limits, 1% accuracy\u003c\/li\u003e\n\u003cli\u003eImproved stability driving reactive loads\u003c\/li\u003e\n\u003cli\u003eOperates from single or split supplies\u003c\/li\u003e\n\u003cli\u003eShutdown\/enable control input\u003c\/li\u003e\n\u003cli\u003eOpen-collector status flags: sink current limit, source current limit, thermal shutdown\u003c\/li\u003e\n\u003cli\u003eFail-safe fixed current limit and thermal shutdown\u003c\/li\u003e\n\u003cli\u003eSlew rate: 1.6 V\/µs\u003c\/li\u003e\n\u003cli\u003eGain-bandwidth product: 3.6 MHz\u003c\/li\u003e\n\u003cli\u003ePCB dimensions: 23.18 mm x 20 mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"dotfry","offers":[{"title":"Default Title","offer_id":47247555887276,"sku":"B150","price":12.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0757\/6436\/7532\/files\/B149.png?v=1789820977","url":"https:\/\/dotfry.com\/products\/a-500-ma-power-op-amp-breakout-board-with-precision-current-limiting","provider":"dotfry","version":"1.0","type":"link"}
