16-Bit Octal DAC with 10ppm/°C (Max) Internal Reference
The 16-bit LTC®2656 combines eight voltage output DACs with guaranteed ±4LSB INL and ±1LSB DNL, and achieves ultralow
AC and DC crosstalk to ensure rock-solid control in precision multichannel open or closed loop systems. The complete family of
quad and octal DACs integrates a precision 1.25V or 2.048V reference that achieves 2ppm/°C typical and 10ppm/°C maximum
temperature coefficient. The ±4LSB (max) INL, ±2mV (max) offset error and ±0.1% (max) gain error DC specifications ensure
you’re designing with the industry’s best unipolar DACs.

Low Glitch 16-Bit Unbuffered VOUT DAC
The unipolar LTC 2641 and bipolar LTC®2642 are a family of unbuffered 16-/14-/12-bit VOUT DACs. They are low power, fast settling
and extremely low glitch DACs that are ideal for AC applications such as waveform generation. With their low offset and drift
specifications, the LTC2641/LTC2642 can be used in precision DC positioning systems, gain and offset adjustment applications,
ATE and data acquisition systems.
