Product Details
●The AD5313/AD5323 are dual 8-/10-/12-bit buffered voltage output DACs in a 16-lead TSSOP package that operate from a single 2.5 V to 5.5 V supply, consuming 230 μA at 3 V. Their on-chip output amplifiers allow the outputs to swing rail-to-rail with a slew rate of 0.7 V/μs. The AD5313/AD5323 utilize 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 references for the two DACs are derived from two reference pins (one per DAC). These reference inputs may be configured as buffered or unbuffered inputs. The parts incorporate a power-on reset circuit, which ensures that the DAC outputs power up to 0 V and remain there until a valid write to the device takes place. There is also an asynchronous active low CLR pin that clears both DACs to 0 V. The outputs of both DACs may be updated simultaneously using the asynchronous LDAC input. The parts contain a power-down feature that reduces the current consumption of the devices to 200 nA at 5 V (50 nA at 3 V) and provides software-selectable output loads while in power-down mode. The parts may also be used in daisy-chaining applications using the SDO pin.
●The low power consumption of these parts in normal operation makes them ideally suited to portable battery-operated equipment. The power consumption is 1.5 mW at 5 V and 0.7 mW at 3 V, reducing to 1 μW in power-down mode.
