Output DACs draw only 120 µA

Output DACs draw only 120 µA

The precision 16-/14-/12-bit unipolar LTC2641 and bipolar LTC2642 unbuffered voltage output D/A converters draw only 120 µA of supply current while settling to within 0.5 LSB for a full-scale step in only 1 µs. These voltage output DACs feature a 0.5-nVs glitch impulse, which is key for ac applications such as waveform generation.

The LTC2641-16 and LTC2642-16 also offer accurate dc specifications, including 16-bit monotonic resolution, ±2 LSB (max) INL, ±2 LSB (max) unipolar offset error, and ±5 LSB (max) gain error. Additionally, these DACs have extremely low drift of 0.1 ppm/°C over the –40° to 85°C industrial temperature range. The LTC2641 is available in tiny DFN-8 and MSOP-8 packages, and the LTC2642 is available in DFN-10 and MSOP-10 packages. (LTC2642-12/LTC2641-12, from $2.95 ea/1,000—available now.)
