Overview
The ADS5474IPFP is a 14-bit, 400-MSPS analog-to-digital converter (ADC) produced by Texas Instruments. This device operates from both a 5-V supply and a 3.3-V supply, providing LVDS-compatible digital outputs. It is part of a family of 12-, 13-, and 14-bit ADCs that operate from 210 MSPS to 500 MSPS. The ADS5474IPFP features an input buffer that isolates the internal switching of the onboard track and hold (T&H) from disturbing the signal source, ensuring a high-impedance input. An internal reference generator simplifies system design. The device is built on Texas Instruments' complementary bipolar process (BiCom3) and is specified over the full industrial temperature range of –40°C to +85°C.
