●
● Dual 10-bit voltage output DAC Single 2.7V to 5.5V supply DNL ± 0.1 LSBs, INL ± 0.4 LSBs Internal programmable voltage reference Low power consumption:
● 5.5 mW, slow mode - 5V supply
● 3.3 mW, slow mode - 3V supply TM TM TMS320, (Q) SPI , and Microwire compatible serial interface Programmable settling time of 1µ s or 3.5µ s typical Power down mode 10nA
DESCRIPTION
A software controlled power down mode is provided that reduces current consumption to 10nA. A reference voltage may also be supplied externally. The WM2637 is programmed with a 16-bit serial word comprising of a latch address, mode DAC control bits and DAC or control data. Excellent performance is delivered with a typical DNL of 0.1 LSBs. The programmable settling time allows the designer to optimize speed versus power consumption. The output stage is buffered by a x2 gain near rail-to-rail amplifier. The device is available in an 8-pin SOIC package ideal for spacecritical applications. Commercial temperature (0° to 70°C) and industrial temperature (-40° to 85 °C) variants are supported.
