DESCRIPTION
The WM2636 is a 12-bit voltage output, resistor string digital-to-analogue converter that can be powered down under software control. Power down reduces current consumption to 10nA.

FEATURES
• 12-bit voltage output DAC
• Single supply from 2.7V to 5.5V
• DNL ±0.5 LSBs, INL ±2.0 LSBs
• Very low power consumption (3V supply):
    - 4.2mW, slow mode
    - 8.1mW, fast mode
• TMS320, (Q)SPI™, and Microwire compatible serial interface
• Programmable settling time of 3.5µs or 1µs typical
• High impedance reference input buffer
• Power down mode 10nA

APPLICATIONS
• Battery powered test instruments
• Digital offset and gain adjustment
• Battery operated/remote industrial controls
• Machine and motion control devices
• Wireless telephone and communication systems
• Speech synthesis
• Arbitrary waveform generation
