Built around the GP8413, it provides 15-bit resolution and supports 0–5V or 0–10V output ranges for embedded control, signal generation, LED dimming, power-supply references, and industrial analog interfaces.\u003c\/p\u003e\u003cp\u003eThe host communicates through I2C. Hardware address selection supports addresses from 0x58 to 0x65, with 0x59 as the default. This allows up to eight devices to share a bus for as many as 16 analog output channels when the full system is planned correctly.\u003c\/p\u003e\u003ch2\u003eGenerate Two Independent Analog Voltage Outputs\u003c\/h2\u003e\u003cp\u003eUse each channel for a separate control or reference signal. The product specification lists output voltage error below 0.2% and linearity error of 0.01%, but final system accuracy also depends on load impedance, supply quality, wiring, calibration, temperature, grounding, and downstream equipment.\u003c\/p\u003e\u003ch3\u003eSelectable 0–5V or 0–10V Range\u003c\/h3\u003e\u003cp\u003eChoose the output range according to the receiving equipment. Confirm the input limits and common-ground requirements of the connected controller, inverter, dimmer, power supply, or analog interface before applying a signal.\u003c\/p\u003e\u003ch3\u003eMultiple I2C Addresses for Expansion\u003c\/h3\u003e\u003cp\u003eAddress selection through A2\/A1\/A0 supports multi-device expansion. Before adding several units, check bus pull-ups, cable length, address configuration, power budget, and startup behavior so outputs do not enter an unintended state.\u003c\/p\u003e\u003ch2\u003eShort-Circuit Protection Is Not Complete System Protection\u003c\/h2\u003e\u003cp\u003eThe unit includes output short-circuit protection, but the surrounding system still needs appropriate wiring, current limits, grounding, transient protection, and fail-safe behavior. For safety-critical motion or process control, use independently rated protective controls.\u003c\/p\u003e\u003cp\u003eTechnical setup details are available in the \u003ca href=\"https:\/\/docs.m5stack.com\/en\/products\/sku\/U012-B\" target=\"_blank\" rel=\"noopener\"\u003eM5Stack DAC2 documentation\u003c\/a\u003e.\u003c\/p\u003e","brand":"LogicBoundless","offers":[{"title":"Default Title","offer_id":49240496079063,"sku":"LB-M5-U012-B","price":9.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/8952\/2135\/files\/1_b825cf48-967d-42f0-9353-2703b4c0f080.webp?v=1783243348","url":"https:\/\/logicboundless.com\/products\/m5stack-gp8413-dual-channel-i2c-dac-unit","provider":"LogicBoundless","version":"1.0","type":"link"}
