Характеристики

AD5320BRMZ, 12-битный ЦАП с выходным сигналом …The AD5320BRMZ is a Rail-to-rail Output 12-bit DAC that operates from a single 2.7 to 5.5V supply consuming 115µA at 3 V. Its on-chip precision output amplifier allows rail-to-rail output swing to be achieved. It utilizes a versatile 3-wire serial interface that operates at clock rates up to 30MHz. The reference for AD5320 is derived from the power supply inputs and thus gives the widest dynamic output range. The part incorporates a power-on reset circuit that ensures that the DAC output powers up to zero volts and remains there until a valid write takes place to the device. The part contains a power-down feature that reduces the current consumption of the device to 200nA at 5V and provides software selectable output loads while in power-down mode. The part is put into power-down mode over the serial interface. The low power consumption of this part in normal operation makes it ideally suited to portable, battery-operated equipment.
