This ADC is optimized for low-power and high-dynamic performance in medical imaging instrumentation and digital munications applications. The MAX1438B operates from a 1.8V single supply and consumes only 913m W (114m W per channel) while delivering a 69.9d B (typ) signal-to-noise ratio (SNR) at a 5.3MHz input frequency. In addition to low operating power, the MAX1438B features a lowpower standby mode for idle periods. An internal 1.24V precision bandgap reference sets the full-scale range of the ADC. A flexible reference structure allows the use of an external reference for applications requiring increased accuracy or a different input voltage range. The reference architecture is optimized for low noise. A single-ended clock controls the data-conversion process. An internal duty-cycle equalizer pensates for wide variations in clock duty cycle. An on-chip phase-locked loop (PLL) generates the high-speed serial low-voltage differential signal (LVDS) clock. The MAX1438B has self-aligned serial LVDS outputs for data, clock, and frame-alignment signals. The output data is presented in two’s-plement format. The MAX1438B offers a maximum sample rate of 64Msps. This device is available in a...
