AD5601,pdf,datasheet下载 2.7 V to 5.5 V,
The AD5601/AD5611/AD5621, members of the nanoDAC庐 family, are single, 8-/10-/12-bit, buffered voltage output DACs that operate from a single 2.7 V to 5.5 V supply, consuming typically 75 渭A at 5 V. The parts come in a tiny SC70 package. Their on-chip precision output amplifier allows rail-to-rail output swing to be achieved. The AD5601/AD5611/AD5621 utilize a versatile 3-wire serial interface that operates at clock rates up to 30 MHz and is compatible with SPI, QSPI鈩? MICROWIRE鈩? and DSP interface standards.
The reference for the AD5601/AD5611/AD5621 is derived from the power supply inputs and, therefore, gives the widest dynamic output range. The parts incorporate a power-on reset circuit, which ensures that the DAC output powers up to 0 V and remains there until a valid write to the device takes place.
The AD5601/AD5611/AD5621 contain a power-down feature that reduces current consumption to typically 0.2 渭A at 3 V.
They also provide software-selectable output loads while in power-down mode. The parts are put into power-down mode over the serial interface.
The low power consumption of these parts in normal operation makes them ideally suited to portable battery-operated equipment. The combination of small package and low power makes these nanoDAC devices ideal for level-setting requirements, such as generating bias or control voltages in space-constrained and power-sensitive applications.
