AD5602,pdf,datasheet下载 2.7 V to 5.5 V,
The AD5602/AD5612/AD5622, a member of the nanoDAC庐 D/A converter family, is a single, 8-/10-/12-bit buffered voltage out DAC that operates from a single +2.7 V to +5.5 V supply consuming <100 碌A at 5 V. The AD5602/AD5612/AD5622 comes in a tiny SC70 package. Its on-chip precision output amplifier allows rail-to-rail output swing to be achieved. The AD5602/AD5612/AD5622 utilizes a 2-wire I2C compatible serial interface that operates in Standard (100 KHz), Fast (400 KHz) and High-Speed (3.4 MHz) Modes.
The reference for AD5602/AD5612/AD5622 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 the DAC output powers up to 0 V 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 <100 nA at 3 V 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. The power consumption is 0.5 mW at 5 V.
