ADS4449EVM

The ADS4449EVM is a circuit board that allows designers to evaluate the performance of Texas Instruments ADS4449, a quad-channel, 14-bit analog-to-digital converter (ADC) operating at sampling rates of up to 250 MSPS. Designed for low-power consumption and high spurious free dynamic range (SFDR), the ADS4449 has low-noise performance and outstanding SFDR over a large input-frequency range. The four ADC channels are separated into two blocks with two ADCs each, and each ADC has programmable gain and programmable test patterns to facilitate the design process. This EVM is ideally suited for mating with the TSW1400 Capture Card for performing a data capture into a capture buffer, uploading the sample data to a PC, performing an FFT, and reporting on SNR, SFDR, and other performance metrics.
