DESCRIPTION
The WM2627 is a quadruple 8-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 1 µA.
FEATURES
• Four 8-bit voltage output DACs
• Dual 2.7V to 5.5V supply (separate digital and analogue supplies)
• DNL ±0.03 LSB, INL ±0.3 LSB typical
• Low power consumption:
- 3mW, slow mode - 3V supply
- 9mW, fast mode - 3V supply
• DSP and microprocessor compatible serial interface
• Programmable settling time of 2.5µs or 8.5µs typical
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
• Arbitrary waveform generation
• Robotics
