Hot-selling and scarce AD5317BRUZ 10 Bit Digital to Analog Converter 4 16-TSSOP spot stock

Product Descriptions

The AD5307/AD5317/AD5327¹  are quad 8-,10-,12-bit bufferedvoltage-output DACs in 16-lead TSSOP that operate from single2.5 V to 5.5 V supplies and consume 400 μA at 3 V. Their onchip output amplifiers allow the outputs to swing rail-to-rail witha slew rate of 0.7 V/μs . The AD5307/AD5317/AD5327 utilizeversatile 3-wire serial interfaces that operate at clock rates up to30 MHz; these parts are compatible with standard SPI, QSPI,MICROWIRE, and DSP interface standards .

The references for the four DACs are derived from two referencepins (one per DAC pair).These reference inputs can be configuredas buffered or unbuffered inputs. Each part incorporates a poweron reset circuit, ensuring that the DAC outputs power up to 0 Vand remain there until a valid write to the device takes place .There is also an asynchronous active low CLR pin that clears allDACs to 0 V. The outputs of all DACs can be updated simultaneously using the asynchronous LDAC input. Each partcontains a power -down feature that reduces the currentconsumption of the device to 300 nA @ 5 V (90 nA @ 3 V).Theparts can also be used in daisy-chaining applications using theSDO pin .

All three parts are offered in the same pinout, allowing users toselect the amount of resolution appropriate for their applicationwithout redesigning their circuit board .
