The MAX12555 is a 3.3V, 14-bit, 95Msps analog-to-digital converter (ADC) featuring a fully differential wideband track-and-hold (T/H) input amplifier, driving a low-noise internal quantizer. The analog input stage accepts single- ended or differential signals. The MAX12555 is optimized for high dynamic performance, low power, and small size. Excellent dynamic performance is maintained from baseband to input frequencies of 175MHz and beyond, making the MAX12555 ideal for intermediate- frequency (IF) sampling applications. Powered from a single 3.3V supply, the MAX12555 con- sumes only 497mW while delivering a typical 72dB sig- nal-to-noise ratio (SNR) performance at a 175MHz input frequency. In addition to low operating power, the MAX12555 features a 300µW power-down mode to conserve power during idle periods. A flexible reference structure allows the MAX12555 to use the internal 2.048V bandgap reference or accept an externally applied reference. The reference structure allows the full-scale analog input range to be adjusted from ±0.35V to ±1.10V. The MAX12555 provides a com- mon-mode reference to simplify design and reduce exter- nal component count in differential analog input circuits. The MAX12555 supports either a single-ended or differ- ential input clock. Wide variations in the clock duty cycle are compensated with the ADC’s internal duty- cycle equalizer (DCE). ADC conversion results are available through a 14-bit, parallel, CMOS-compatible output b
