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
