简  介:WM2604 Quad 10-Bit Serial Input Voltage Output DAC Production Data, June 1999, Rev 1.0 FEATURES Four 10-bit voltage output DACs Dual 2.7V to 5.5V supply (separate digital and analogue supplies) DNL ± 0.1 LSB, INL ± 0.4 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 4 s or 12 s typical DESCRIPTION The WM2604 is a quadruple 10-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 10nA. The device has been designed to interface efficiently to industry standard microprocessors and DSPs, including the TMS320 family. The WM2604 is programmed with a 16-bit serial word comprising of a DAC address, individual DAC control bits and a 10-bit value. The WM2604 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 ±0.1 LSB. The settling time of the DAC is programmable to allow the d……
