The analog input stage accepts singleended or differential signals. The MAX12553 is optimized for low-power, small size, and high dynamic performance. Excellent dynamic performance is maintained from baseband to input frequencies of 175MHz and beyond, making the MAX12553 ideal for intermediatefrequency (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 operating power, the MAX12553 features a 150µW powerdown 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 common-mode reference to simplify design and reduce external component count in differential analog input circuits. The MAX12553 supports both a single-ended and differential input clock drive. 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 bus. The digital output format is pin selectable to be either two’s complement or Gray code. A data-valid indicator eliminates external components that are normally required for reliable digital interfacing. A separate digital power input accepts a wide 1.7V to 3.6V supply, allowing the MAX12553 to interface with various logic levels. The MAX12553 is available in a 6mm x 6mm x 0.8mm, 40-pin thin QFN package with exposed paddle (EP), and is specified for the extended industrial (-40°C to +85°C) temperature range. See the Pin-Compatible Versions table for a complete family of 14-bit and 12-bit high-speed ADCs.
