DescriptionThe AD5304/AD5314/AD5324 are quad 8-, 10- and 12-bitbuffered voltage output DACs in a 10-lead microSOIC packagethat operate from a single 2.5 V to 5.5 V supply consuming500 A at 3 V. Their on-chip output amplifiers allow rail-torailoutput swing to be achieved with a slew rate of 0.7 V/s.A 3-wire serial interface is used which operates at clock ratesup to 30 MHz and is compatible with standard SPI, QSPI,MICROWIRE and DSP interface standards.
The references for the four DACs AD5304/AD5314/AD5324 are derived from one referencepin. The outputs of all DACs may be updated simultaneouslyusing the softwareLDAC function. The parts incorporate apower-on-reset circuit that ensures that the DAC outputs powerup to zero volts and remain there until a valid write takes placeto the device. The parts contain a power-down feature thatreduces the currentconsumption of the device to 200 nA @ 5 V(80 nA @ 3 V).
The low power consumption of these parts AD5304/AD5314/AD5324 in normal operationmakes them ideally suited to portable battery-operated equipment.The power consumption is 3 mW at 5 V, 1.5 mW at 3 V, reducingto 1 W in power-down mode.
The AD5304/AD5314/AD5324* are quad 8-, 10-, and 12-bit buffered voltage output DACs in 10-lead MSOP and 10-lead LFCSP packages that operate from a single 2.5 V to 5.5 V supply, consuming
The AD5324 is designed as one kind of 2.5 V to 5.5 V, 115 uA, parallel interface single voltage-output 8-/10-/12-bit DAC that can be used in (1)portable battery-powered instruments; (2)digital gain and offset adjustment; (3)programmable voltage and current sources; (4)programmable attenuators; (5)industrial process control applications. This device incorporates an on-chip output buffer that can drive the output to both supply rails, and is also available in Thin Shrink Small Outline Packages (TSSOP).
Features of the AD5324 are:(1)low power operation: 115 uA @ 3 V, 140 uA @ 5 V; (2)power-down to 80 nA @ 3 V, 200 nA @ 5 V via PD Pin; (3)2.5 V to 5.5 V power supply; (4)double-buffered input logic; (5)guaranteed monotonic by design over all codes; (6)buffered/unbuffered reference input options; (7)output range: 0VREF or 02 VREF; (8)power-on reset to zero volts; (9)simultaneous update of DAC outputs via LDAC pin; (10)asynchronous CLR facility; (11)low power parallel data interface; (12)on-chip rail-to-rail output buffer amplifiers; (13)temperature range: 40 to +105 .
The absolute maximum ratings of the AD5324 can be summarized as:(1)VDD to GND: -0.3 V to +7 V;(2)Digital Input Voltage to GND: -0.3 V to VDD+0.3 V;(3)Digital Output Voltage to GND: -0.3 V to VDD+0.3 V;(4)Reference Input Voltage to GND: -0.3 V to VDD+0.3 V;(5)Operating Temperature Range Industrial (B Version): -40°C to +105°C;(6)Storage Temperature Range: -65°C to +150°C;(7)Junction Temperature: 150°C.
