10-bit DAC with SPI and fast settling
The TLV5606CDGK is a single-channel, 10-bit, voltage-buffered digital-to-analog converter from Texas Instruments, built on a String DAC architecture.
The 0.65 mm pin pitch is a standard layout that routes out on a two-layer board without difficulty. The external reference input (REF) requires a clean bypass cap close to the pin — the datasheet recommends 0.1 µF ceramic within 5 mm of the VREF pin for the 20 µs settling spec to hold.
Linearity and output accuracy
Integral non-linearity (INL) is ±0.5 LSB max, and differential non-linearity (DNL) is ±0.2 LSB max. The DNL spec guarantees monotonicity — the output code never steps backward — which matters for servo loops or sweep generators where a non-monotonic transition would cause a control reversal. With a 10-bit resolution and a 5 V reference, the 1 LSB step is 4.88 mV, and the ±0.5 LSB INL means the output stays within 2.44 mV of the ideal transfer function.
