4-channel, 14-bit A/D runs at 250 MHz

The ADS4449 4-channel 14-Bit A/D converter features a 250 MHz maximum sample rate and a small 10-mm by 10-mm BGA144 package. The IC uses 365 mW/channel typical and has a 400 mW total standby mode. Spurious-free dynamic range (SFDR) is 86 dBc, typical with a 170 MHz input frequency.

The chips integral nonlinearity is ±1.5 LSB typical at room temperature and ±5.25 LSB maximum over the -40° to 85°C operating range. SNR is 67.5 dBFS worst case and 69 dBFS typical at 170 MHz f_in and signal-to-noise and distortion ratio (SINAD) is 68 dBFS typical. The IC costs $199.85 ea/1,000
