Voltage Output DACs

Linear Technology's Voltage Output DAC family is a mix resistor string and R-2R architecture digital-to-analog converters. The family consists of precision, buffered and unbuffered rail-to-rail VOUT DACs with up to ±1 LSB INL and DNL specifications and excellent offset and gain error. These DACs work well in a wide variety of open-loop or closed-loop systems, adjusting gain, offset and many other signals. The unbuffered16-/14-/12-bit LTC2641 and LTC2642 VOUT DACs offer fast settling and the lowest mid-scale glitch in the industry, perfect for both DC and AC applications such as waveform generation.
