Hot-selling and scarce AD5320BRT 140 uA, Rail-to-Rail Output 12-Bit DAC SOT23-6 spot stock

Product Descriptions

The AD5320 is a single, 12-bit buffered voltage out DAC thatoperates from a single +2.7 V to +5.5 V supply consuming115 µA at 3 V . Its on-chip precision output amplifier allowsrail-to-rail output swing to be achieved . The AD5320 utilizes aversatile three-wire serial interface that operates at clock rates upto 30 MHz and is compatible with standard SPI™, QSPI™,MICROWIRE™ and DSP interface standards .

The reference for AD5320 is derived from the power supplyinputs and thus gives the widest dynamic output range . The partincorporates a power-on-reset circuit that ensures that the DACoutput powers up to zero volts and remains there until a validwrite takes place to the device . The part contains a power-downfeature that reduces the current consumption of the device to200 nA at 5 V and provides software selectable output loadswhile in power-down mode . The part is put into power-downmode over the serial interface .

The low power consumption of this part in normal operationmakes it ideally suited to portable battery operated equipment .The power consumption is 0.7 mW at 5 V reducing to 1 µW inpower-down mode .

The AD5320 is one of a family of pin-compatible DACs . TheAD5300 is the 8-bit version and the AD5310 is the 10-bitversion . The AD5300/AD5310/AD5320 are available in 6-leadSOT-23 packages and 8-lead µSOIC packages .
