●
● Quad 12-bit DAC voltage output DAC Dual 2.7V to 5.5V supply (separate digital and analogue supplies) DNL ± 0.4 LSB, INL ± 1.5 LSB Low power consumption: 5.5mW, slow mode − 5V supply 3.3mW, slow mode − 3V supply TMS320, (Q)SPI™ , and Microwire™ compatible serial interface Programmable settling time of 4µ s or 12µ s typical
DESCRIPTION
A hardware controlled mode is provided that powers down all DACs. Power down reduces current consumption to 10nA. The WM2614 is programmed with a 16-bit serial word comprising of a DAC address, individual DAC control bits and a 12-bit value. The WM2614 has provision for two supplies: one supply for the serial interface (DVDD, DGND) and one for the DACs, reference buffers and output buffers (AVDD, AGND). This enables a typical application where the device can be controlled via a microprocessor operating on a 3V supply, with the DACs operating on a 5V supply. Alternatively, the supplies can be tied together in a single supply application. Excellent performance is delivered with a typical DNL of 0.4 LSBs.
