14-bit, 65msps, 3.3v Adc Integrated Products

The MAX12553 is a 3.3V, 14-bit, 65Msps 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 MAX12553 is optimized for low-power, small size, and high dynamic perfor- mance. Excellent dynamic performance is maintained from baseband to input frequencies of 175MHz and beyond, making the MAX12553 ideal for intermediate- frequency (IF) sampling applications. Powered from a single 3.15V to 3.60V supply, the MAX12553 consumes only 363mW while delivering a typical signal-to-noise (SNR) performance of 71dB at an input frequency of 175MHz. In addition to low oper- ating power, the MAX12553 features a 150W power- down mode to conserve power during idle periods. A flexible reference structure allows the MAX12553 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 MAX12553 provides a com- mon-mode reference to simplify design and reduce exter- nal component count in differential Analog input circuits. The MAX12553 supports both a single-ended and dif- ferential input Clock drive. Wide variations in the Clock duty cycle are compensated with the ADCs internal duty-cycle equalizer (DCE).
