| DAC7578SRGET from TI/BB, Texas Instruments 100pcs , VQFN24,12-bit, Octal Channel, Ultra-Low Glitch, Voltage Output, 2-Wire Interface DAC 24-VQFN -40 to 125 |
| FEATURES DESCRIPTION23• Relative Accuracy:The DAC5578 (8 bit), DAC6578 (10 bit), and– DAC5578 (8 bit): 0.25LSB INL DAC7578 (12 bit) are low-power, voltage-output, octalchannel, digital-to-analog converters (DACs). The– DAC6578 (10 bit): 0.5LSB INLdevices are monolithic, provide good linearity,and– DAC7578 (12 bit): 1LSB INLminimize undesired code-to-code transient voltages• Glitch Energy: 0.15nV-s (glitch).• Power-On Reset to Zero Scale or MidscaleThe devices use a versatile, 2-wire serial interface2– Devices in the TSSOP Package Reset to that is I C-compatible and operates at clock rates ofup to 3.4MHz. Multiple devices can share the sameZero Scalebus.– Devices in the QFN Package Reset to ZeroScale or Midscale The devices incorporate a power-on-reset (POR)circuit that ensures the DAC output powers up to• Ultra-Low Power Operation: 0.13mA/ch at 5Vzero-scale or midscale until a valid code is written to• Wide Power-Supply Range: +2.7V to +5.5Vthe device. These devices also contain a power-down2• 2-Wire Serial Interface ( I C™ compatible)feature, accessed through the serial interface, thatreduces the current consumption of the devices to• Temperature Range: –40°C to +125°Ctypically 0.42mA at 5V. Power consumption is typically2.32mW at 3V, reducing to 0.68mW in power-downAPPLICATIONSmode. The low power consumption and small• Portable Instrumentationfootprint make these devices ideal for portable,• Closed-Loop Servo Controlbattery-operated equipment.• Process ControlThe DAC5578, DAC6578, and DAC7578 are drop-in• Data Acquisition Systemsand functionally-compatible with the DAC7678. Alldevices are available in a 4x4, QFN-24 package andAV VDD REFINa TSSOP-16 package.DACx5788-/10-/12-BitDAC Register H V HData Buffer H OUTDACRELATED DEVICES 8-BIT 10-BIT 12-BIT8-/10-/12-BitData Buffer G DAC Register G V GOUTDACPin- and Function-Compatible— — DAC76788-/10-/12-Bit(w/internal reference)Data Buffer F DAC Register F V FOUTDACPin- and Function-Compatible DAC5578 DAC6578 DAC75788-/10-/12-BitData Buffer E DAC Register E V EOUTDAC8-/10-/12-BitData Buffer D DAC Register D V DOUTDAC8-/10-/12-BitDAC Register C V CData Buffer C OUTDAC8-/10-/12-BitData Buffer B DAC Register B V BOUTDAC8-/10-/12-BitDAC Register A V AData Buffer A OUTDACSCLInput Control Logic Buffer Control Register ControlPower-DownSDAControl LogicControl LogicADDR0 ADDR1 LDAC RSTSEL CLR GND1Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of TexasInstruments semiconductor products and disclaimers thereto appears at the end of this data sheet.22I C is a trademark of NXP Semiconductors.3All other trademarks are the property of their respective owners..Copyright 2010, Texas Instruments IncorporatedProducts conform to specifications per the terms of the TexasInstruments standard warranty.
