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.
