THEORY OF OPERATION The AD5330/AD5331/AD5340/AD5341 are single resistor- string DACs fabricated on a CMOS process with resolutions of 8, 10, and 12 bits, respectively. They are written to using a parallel interface. They operate from single supplies of 2.5 V ...

AD5330/AD5331/AD5340/AD5341 PARALLEL INTERFACE The AD5330, AD5331, and AD5340 load their data as a single 8-, 10-, or 12-bit word, while the AD5341 loads data as a low byte of eight bits and a high byte containing four bits. DOUBLE-BUFFERED INTERFACE ...
Page 19
POWER-DOWN MODE The AD5330/AD5331/AD5340/AD5341 have low power consumption, dissipating only 0.35 mW with supply and 0.7 mW with supply. Power consumption can be further reduced when the DAC is not in use by putting ...

AD5330/AD5331/AD5340/AD5341 SUGGESTED DATABUS FORMATS In most applications, GAIN and BUF are hard-wired. However, if more flexibility is required, they can be included in a databus. This enables the user to software program GAIN, giving the option of doubling the resolution ...
