Powered from a single 3.3V supply, the MAX12554 consumes only 429mW while delivering a typical 70.9dB signal-to-noise ratio (SNR) performance at a 175MHz input frequency. In addition to low operating power, the MAX12554 features a 300µW power-down mode to conserve power during idle periods.
A flexible reference structure allows the MAX12554 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 MAX12554 provides a common- mode reference to simplify design and reduce external component count in differential analog input circuits.
The MAX12554 supports either a single-ended or differential input clock. Wide variations in the clock duty cycle are compensated with the ADC's internal dutycycle 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 MAX12554 to interface with various logic levels.
The MAX12554 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.
