Smallest Dual 14-Bit Voltage Output DAC Fits in 8-Pin SOIC Footprint

摘要

Linear Technology introduces the LTC1654; a dual 14-bit voltage output Digital-to-Analog Converter (DAC) in the narrow 16-pin SSOP package. This tiny dual DAC draws only 225μA per DAC (typ) from a single 3V to 5V supply. Two rail-to-rail output buffers and a 3-wire cascadable serial interface allow ease of use and conserves system board space. High resolution, small size, and low power make this low cost, dual DAC ideal for digital calibration, industrial process control, and optical networking applications. The LTC1654 offers two individually programmable speed modes (3.5μs settling time and 8μs settling time), which allow the user to choose speed vs. power based on the application. The reference input can be conveniently tied to the supply and the output can swing from 0V to either V_(CC) or V_(CC)/2 depending on which gain mode is selected.
