Overview
The ADS4449IZCR is a high-performance, quad-channel, 14-bit analog-to-digital converter (ADC) produced by Texas Instruments. This device is designed for low power consumption and high spurious-free dynamic range (SFDR), making it ideal for applications requiring high-linearity and low-noise performance. The ADS4449 operates at a maximum sampling rate of 250 million samples per second (MSPS) and features a DDR LVDS digital output interface. It is packaged in a 144-terminal NFBGA (ZCR) package, measuring 10.00 mm × 10.00 mm, and operates over a temperature range of -40°C to 85°C.
