ADC Widens Dynamic Performance

Improving receiver performance in a multitude of applications, the ADS5440 13-bit a/d converter specifies a spurious-free dynamic range (SFDR) of 79 dB, signal-to-noise ratio (SNR) of 68 dB, and sampling rates up to 210 Msamples/s. Input frequency is 230 MHz. The device operates from a 5V supply, while providing LVDS-compatible digital outputs from a 3.3V supply. To simplify system requirements, it integrates both a reference voltage and an input buffer. Typical applications include software defined radios, basestation power amplifier linearization systems and test and measurement systems. Sampling now with production expected in the fourth quarter, price is $65 each/1,000. TEXAS INSTRUMENTS INC., Dallas, TX. (800) 477-8924.
