12-bit DAC with 20 µs settling and SPI
The TLV5616IDGK is a 12-bit voltage-buffered DAC from Texas Instruments, using a string DAC architecture for monotonic performance. It settles to within 1/2 LSB in 20 µs, making it suited for closed-loop control and set-point generation in industrial and instrumentation systems. Data is written via an SPI-compatible serial interface, and the output is driven by a rail-to-rail buffer that can source or sink current. The reference is external, so the full-scale output range is set by the voltage applied to the REF pin.
Package and rework considerations
Supplied in a tube, which is the standard delivery format for prototype and low-volume builds. The package is RoHS3 compliant (lead-free), with no exemption conflicts for EU RoHS directives.
Linearity and monotonicity
Integral non-linearity is ±1.9 LSB maximum, and differential non-linearity is ±0.5 LSB maximum. The DNL spec guarantees monotonicity — every digital code step produces a positive output change, which matters in servo loops where non-monotonic behavior could cause oscillation or hunting.
