WM2619

WM2619 12-bit Parallel Input Voltage Output DAC Production Data, June 1999, Rev 1.0 FEATURES 12-bit voltage output DAC Single supply 2.7V to 5.5V operation DNL ±0.4 LSB, INL ±1.5 LSB Settling time 1µs typical Low power consumption 8mW typical in slow mode - 5V supply 4.3mW typical in fast mode - 3V supply Power down mode DESCRIPTION The WM2619 is a 12-bit voltage output, resistor string, digital-toanalogue converter. A hardware controlled power down mode is provided that reduces power consumption to 50nW. In normal operation the device dissipates 8mW at 5V or 4.3mW at 3V. The device has been designed to interface efficiently to industry standard microprocessors and DSPs. Excellent performance is delivered with a typical DNL of 0.4 LSBs and a settling time of 1µ s. The output stage is buffered by a x2 gain near rail-to-rail amplifier, which features a Class A output stage. The 12 data bits are double-buffered enabling the output to be asynchronously updated under hardware control. The device is available in a 20-pin TSSOP package. Commercial temperature (0° to 70°C) and Industrial temperature (-40° to 85°C) variants are supported.
