2.7 V to 5.5 V, 140 μA, Rail-to-Rail Output 8-Bit DAC in a SOT-23 AD5300 00471-001 FEATURES Single 8-Bit DAC 6-Lead SOT-23 and 8-Lead MSOP Packages Micropower Operation: 140 μA @ 5 V Power-Down to 200 nA @ 5 V, 50 nA @ 3 V 2.7 V to 5.5 V Power Supply Guaranteed Monotonic by Design Reference Derived from Power Supply Power-On Reset to 0 V 3 Power-Down Functions Low Power Serial Interface with Schmitt-Triggered Inputs On-Chip Output Buffer Amplifier, Rail-to-Rail Operation SYNC Interrupt Facility Qualified for automotive applications APPLICATIONS Portable Battery-Powered Instruments Digital Gain and Offset Adjustment Programmable Voltage and Current Sources Programmable Attenuators GENERAL DESCRIPTION The AD5300 is a single, 8-bit buffered voltage output DAC that operates from a single 2.7 V to 5.5 V supply, consuming 115 μA at 3 V. Its on-chip precision output amplifier allows rail-to-rail output swing to be achieved. The AD5300 uses a versatile 3-wire serial interface that operates at clock rates up to 30 MHz and is compatible with standard SPI®, QSPI™, MICROWIRE™, and DSP interface standards. The reference for the AD53001 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 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 200 nA at 5 V and provides software selectable output loads while in powerdown 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 0.7 mW at 5 V, reducing to 1 μW in power-down mode. The AD5300 is one of a family of pin-compatible DACs. The AD5310 is the 10-bit version, and the AD5320 is the 12-bit version. The AD5300/AD5310/AD5320 are available in 6-lead SOT-23 packages and 8-lead MSOP packages. Rev.
