Texas Instruments DAC5687 16-bit, 500 MSPS 2x-8x Interpolating Dual-Channel Digital-to-Analog Converter (DAC) DAC5687IPZPR

The DAC5687IPZPR is a dual-channel, 16-bit digital-to-analog converter (DAC) capable of operating at a maximum sampling rate of 500 MSPS. It features selectable 2x, 4x, and 8x interpolation, which enhances the output signal quality. The device includes an on-chip phase-locked loop (PLL) and voltage-controlled oscillator (VCO) for clock multiplication, as well as full IQ compensation for offset, gain, and phase adjustments. This DAC offers flexible input options, including FIFO with latch, even/odd multiplexed input, and single-port demultiplexed input. It also incorporates a complex mixer with a 32-bit numerically controlled oscillator (NCO) and fixed frequency mixers for improved frequency handling. The output is differential and scalable, ranging from 2 mA to 20 mA. The DAC5687IPZPR operates within a temperature range of -40¬8C to 85¬8C and is packaged in a 100-pin HTQFP format. It is pin-compatible with the DAC5686, allowing for easy integration into existing designs. This device is suitable for applications in cellular base transceiver stations and cable modem termination systems, making it a versatile choice for high-performance signal processing tasks.
