DESCRIPTION

The WM2631 is an octal, 10-bit, resistor string digital-toanalogue converter. The eight individual DACs contained in the IC can be switched in pairs between fast and slow (low power) operation modes, or powered down, under software control. Alternatively, the whole device can be powered down, reducing current consumption to less than 0.1µA.

FEATURES

• Eight 10-bit DACs in one package

• Dual supply 2.7V to 5.5V operation

• DNL ±0.1 LSBs, INL ±0.5 LSBs typical

• Programmable settling time / power (1.0µs typical in fast mode)

• Internal programmable voltage reference

• Microcontroller compatible serial interface

• Power down mode ( < 0.1µA)

• Monotonic over temperature

• Data output for daisy chaining

APPLICATIONS

• Battery powered test instruments

• Digital offset and gain adjustment

• Battery operated / remote industrial controls
