Its architecture is a current sink and current source, meaning each of its two DAC channels can either pull current to ground (sink) or push current out (source), depending on the code written over the I2C interface. The output is unbuffered, so the load impedance directly sets the voltage compliance range. This part is designed for trimming and calibration applications where you need to inject or absorb a precise DC current into a node — think laser diode bias, VCO tuning, or sensor offset nulling. ## Temperature range and environment Rated for -40°C to 85°C, this DAC is comfortable in industrial control cabinets, outdoor telecom enclosures, and automotive cabin environments. The surface-mount 8-uMAX/uSOP package is suitable for reflow soldering in standard PCB assembly lines. ## Lifecycle and sourcing reality The DS4432U+T&R carries an Active product status from Maxim Integrated (now part of Analog Devices). It is ROHS3 compliant. This is a current-production part, not an NRND or EOL line, so there is no last-time-buy pressure. For BOM planning, the part is available through independent distribution channels and is sourced to order against an RFQ.","metaTitle":"DS4432U+T&R 7-Bit I2C Current DAC, 2-Ch, 8-uMAX/uSOP","metaDescription":"Maxim DS4432U+T&R 7-bit current DAC with I2C interface, dual channel, current sink/source output, 8-uMAX/uSOP package, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["DC-DC Power Modules"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Output Type":"Current - Unbuffered","Architecture":"Current Sink, Current Source","INL/DNL (LSB)":"±1 (Max), ±0.5 (Max)","Mounting Type":"Surface Mount","Data Interface":"I²C","Number of Bits":"7","Package / Case":"8-TSSOP, 8-MSOP (0.118\\\", 3.00mm Width)","lifecycle_stage":"eol_hot","Differential Output":"No","Operating Temperature":"-40°C ~ 85°C","Supplier Device Package":"8-uMAX/uSOP","Number of D/A Converters":"2","Voltage - Supply, Analog":"2.7V ~ 5.5V","Voltage - Supply, Digital":"2.7V ~ 5.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.94","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.94000","currency":"USD"},{"qty":10,"price":"$1.74000","currency":"USD"},{"qty":25,"price":"$1.64120","currency":"USD"},{"qty":100,"price":"$1.39830","currency":"USD"},{"qty":250,"price":"$1.31300","currency":"USD"},{"qty":500,"price":"$1.14888","currency":"USD"},{"qty":1000,"price":"$0.95192","currency":"USD"},{"qty":3000,"price":"$0.88627","currency":"USD"},{"qty":6000,"price":"$0.85345","currency":"USD"}]},"links":{"datasheetUrl":"https://www.analog.com/media/en/technical-documentation/data-sheets/DS4432.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the resolution of DS4432U+T&R?","answer":"The DS4432U+T&R is a 7-bit DAC, giving 128 discrete output current levels per channel."},{"question":"What is the output type of DS4432U?","answer":"The output is current, unbuffered, and the architecture supports both current sink and current source modes."},{"question":"How do I use DS4432U+T&R with a microcontroller?","answer":"Connect the SDA and SCL pins to the microcontroller's I2C bus.
