简 介:WM2613 Byte-wide Parallel Input, 12-bit Voltage Output DAC
Production Data, June 1999, Rev 1.0
FEATURES
Dual 12-bit voltage output DAC Dual supply 2.7V to 5.5V operation DNL ± 0.4 LSB, INL ± 1.5 LSB Programmable settling time 1 s or 3 s typical 8-bit micro controller compatible interface Power down mode (10nA)
DESCRIPTION
The WM2613 is a 12-bit voltage output, resistor string, digital-toanalogue converter. The DAC can be powered down under software or hardware control, reducing power consumption to 10nA. The device has an 8-bit microcontroller compatible parallel interface. The eight data LSBs, the four data MSBs, and the three control bits are written using three different addresses. Excellent performance is delivered with a typical DNL of 0.4 LSBs. The output stage is buffered by a x2 gain near rail-to-rail amplifier, which features a Class A output stage (slow mode, class AB). The settling time of the DAC is software programmable to allow the designer to optimize speed versus power dissipation. 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.
