Texas Instruments DAC5662 12 bit 275 MSPS Dual Digital to Analog Converter DAC5662IPFBRG4

The DAC5662 is a dual-channel, 12-bit digital-to-analog converter (DAC) capable of operating at update rates up to 275 MSPS. It features two parallel input ports with independent clocks and data latches, allowing for flexible data handling, including interleaved operation. The device is designed for differential transformer-coupled outputs and supports a full-scale output current ranging from 2 mA to 20 mA, with options for different impedance ratios. This DAC is characterized by high dynamic performance, with a spurious-free dynamic range (SFDR) of 85 dBc at 5 MHz and intermodulation distortion (IMD3) of 78 dBc at specific frequencies. It includes an on-chip 1.2-V voltage reference, which is temperature compensated, and can operate with a single supply voltage between 3 V and 3.6 V. The DAC5662 is housed in a 48-pin thin quad flatpack (TQFP) package and is rated for industrial temperature ranges from -40¬8C to 85¬8C, making it suitable for various applications, including cellular base transceiver stations and medical instrumentation.
