The ADS5546 is a high performance 14-bit 190 MSPS A/D converter. It offers state of the art functionality and performance while applying advanced techniques to minimize board space. Using an internal sample and hold and low jitter clock buffer, the ADC supports high SNR and high SFDR at high input frequencies. In a compact 48-pin QFN, the device offers unprecedented digital output flexibility with fully differential DDR (Double Data Rate) LVDS or parallel CMOS options. The ADS5546 also includes an internal reference, but the traditional reference pins have been eliminated, along with the need for external decoupling. Alternatively, the device can also be driven with an external reference. For applications where power is important, the ADS5546 offers innovative solutions, such as power down modes and the possibility of power scaling at lower sample rates. The device is specified over the -40C to +85C operating range.
