ADS5444-EP 增强型产品 13 位 250Msps 模数转换器

The ADS5444 is a 13-bit 250-MSPS analog-to-digital converter (ADC) that operates from a 5-V supply, while providing LVDS-compatible digital outputs from a 3.3-V supply. The ADS5444 input buffer isolates the internal switching of the onboard track and hold (T&H) from disturbing the signal source. An internal reference generator is also provided to further simplify the system design. The ADS5444 has outstanding low noise and linearity over input frequency.

The ADS5444 is available in an 80-pin TQFP PowerPAD™ package. The ADS5444 is built on a state-of-the-art Texas Instruments complementary bipolar process (BiCom3X) and is specified over the full military temperature range (-55°C to 125°C).
