DESCRIPTION
The WM2614 is a quadruple 12-bit voltage output, resistor string, digital-to-analogue converter. Each DAC can be individually powered down under software control. A hardware controlled mode is provided that powers down all DACs. Power down reduces current consumption to 10nA.
FEATURES
• Quad 12-bit DAC voltage output DAC
• Dual 2.7V to 5.5V supply (separate digital and analogue supplies)
• DNL ±0.4 LSB, INL ±1.5 LSB
• Low power consumption:
- 5.5mW, slow mode - 5V supply
- 3.3mW, slow mode - 3V supply
• TMS320, (Q)SPIä, and Microwireä compatible serial interface
• Programmable settling time of 4ms or 12ms typical
APPLICATIONS
• Battery powered test instruments
