12-bit voltage-buffered DAC with SPI control
The TLV5616IDR is a single-channel 12-bit digital-to-analog converter using a string DAC architecture with a voltage-buffered output — the output stage can source or sink current without an external op-amp, simplifying the analog front-end design for set-point generation in industrial control loops. Data is written via a standard SPI interface, making it a drop-in fit for microcontrollers with a spare SPI port — no parallel bus required, and the serial protocol keeps the pin count to just 8 pins in the SOIC package. The 20 µs settling time to ±0.5 LSB means the output updates at roughly 50 kHz for a full-scale step — adequate for slow-loop process control, programmable voltage references, and sensor calibration trimming where update rates stay below 10 kHz.
Supply rails and temperature grade
The analog and digital supply pins share the same 2.7 V to 3.3 V or 5 V range — a single 3.3 V or 5 V rail powers both sides, eliminating the need for a separate analog supply regulator in many mixed-signal designs. Rated for the industrial temperature range of -40°C to 85°C, the device operates across the full ambient span of factory-floor electronics, outdoor telecom cabinets, and automotive cabin environments without derating. The external reference input (REF) sets the full-scale output voltage — a precision reference like the REF5025 or a filtered supply rail determines the span, so the absolute accuracy depends on the reference quality, not the DAC itself.
Package and lifecycle
Housed in an 8-pin SOIC package (8-SOIC, 3.90 mm width), the TLV5616IDR is supplied on tape and reel for automated pick-and-place assembly — the same footprint as industry-standard SOIC-8, so no PCB layout change from other 8-pin SOIC DACs.
