DAC-Slide5

The LTC2600 is a family of DACs ideal for closed loop systems. Pin-compatible choices include 16-, 14-, or 12-bits of resolution, SPI and I²C interfaces, and one, two, four, or eight DACs in a small package. All of these DACs are 16-bit, 14-bit, and 12-bit monotonic as pointed out by the red arrow. A differential nonlinearity of ±1 LSB maximum guarantees the DAC’s monotonicity, meaning the analog output always increases or stays the same with an increase in the digital code, but never decreases. The 16-bit DACs in the LTC2600 family offer ±64 LSB INL. The differences in INL will be discussed in more detail a bit later.
