The MAX12554 is a 3.3V, 14-bit, 80Msps 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 MAX12554 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 MAX12554 ideal for intermediate frequency (IF) sampling applications.
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.
