12-Bit,2.3Gsps Multi-Nyquist DACDelivers Industry’s Best SFDR at High IFEnables Wideband and Direct RF Communications at One-Third the Power

The MAX19692 12-bit, 2.3Gsps DAC digitally synthesizes high-frequency and wideband signals in baseband and inhigher Nyquist zones. This DAC has excellent spurious and noise performance, and can synthesize wideband signals (up to1GHz bandwidth) in the frequency range from DC to more than 2GHz. This device synthesizes signals with high SNR andexcellent gain flatness in the first three Nyquist zones directly, eliminating the need for upconversion stages in a radio trans-mitter. With its unique ability to generate broadband signals over a wide frequency range, the MAX19692 enablesultra-high-data-rate wireless modems, multistandard software radio transmitters, wideband radar, arbitrary waveform generators, andautomatic test equipment.

16-Bit, 250Msps Dual DAC Delivers -164dBFS/Hz Noise Density at 296mWThe MAX5875/MAX5878/MAX5895/MAX5898 families of 200/250/500/500Msps dual DACs deliver superior

dynamic performance (noise spectral density, SFDR, IMD, ACLR) at very low power. Offered in 16-/14-/12-bit, pin-compatible versions with CMOS or LVDS inputs, these DACs provide options to optimize performanceand cost.

To simplify the FPGA interface and filter design, reduce system cost, and improve reliability, the MAX5898/MAX5895/MAX5894/MAX5893 integrate interpolation filters, which reduce the DAC input word rate and relaximage-filter requirements. To further simplify design, this family integrates a digital quadrature modulator that enablesboth zero-IF and direct-IF transmit architectures.

Updated 12-Bit, 250Msps ADC FamilyHas Best SNR and SFDRPin-Compatible, 12-/10-/8-Bit ADCs Ideal for Broadband Communications

The MAX1215N (12-bit, 250Msps), MAX1214N (12-bit, 210Msps), and MAX1213N (12-bit, 170Msps) ADCshave the industry's highest SNR or SFDR from baseband to input frequencies beyond 300MHz. This remarkablewideband performance is achieved while consuming only 720mW to 886mW.

For applications that require two channels, the MAX1219 (12-bit, 210Msps), MAX1218 (12-bit, 170Msps), andMAX1217 (12-bit, 125Msps) ADCs offer similar outstanding performance in a dual-channel configuration. Thecombination of superior, high-IF dynamic performance and a high sample rate allow the user to select receiver archi-tectures that can sample large bandwidths while eliminating intermediate RF downconversion stages. This, inconjunction with the available dual channels, reduces system cost and complexity while saving board space.
