Texas Instruments has introduced its 16-bit, dual channel, 800 MSPS digital-to-analog converter (DAC). The device builds on design of the DAC5687 and continues to push the space and performance boundaries in transmit DAC solutions for wireless base stations, software-defined radio applications and multi-frequency test equipment the Model DAC5688 is 16-bit, dual channel, 800 MS/sec DAC designed in 64-pin, 9 x 9 mm QFN package. Digital inverse SINC filter compensates for natural DAC sin (x)/x frequency roll-off and digital quadrature modulator correction feature allows IQ compensation of phase, gain, and offset. Unit includes dual CMOS data bus that provides 250 Mbps input data transfer/DAC channel. Input data can be interpolated 2, 4, or 8 times by on-board digital interpolating FIR filters. The DAC5688 is available now in 64-pin quad flat no-lead (QFN) package and is priced at $29.95 in 1,000-piece quantities (suggested resale pricing).
