MAX12529 Dual, 96Msps, 12-Bit, IF/Baseband ADC

The MAX12529 is a dual, 96Msps, 12-bit Analog-to-digital converter (ADC) featuring fully differential wideband track-and-hold (T/H) inputs, driving internal quantizers. The MAX12529 is optimized for low power, small size, and high dynamic performance in intermediate frequency (IF) and baseband sampling applications. This dual ADC operates from a single 3.3V supply, consuming only 980mW while delivering a typical 69.7dB signal-to-noise ratio (SNR) performance at a 175MHz input frequency. The T/H input stages accept 58d single-ended or differential inputs up to 350MHz. In addition to low operating power, the MAX12529 features a 0.66mW power-down mode to conserve power during idle periods.
A flexible reference structure allows the MAX12529 to use the internal 2.048V bandgap reference or accept an externally applied reference and allows the reference to be shared between the two ADCs The reference structure allows the full-scale Analog input range to be adjusted from 0.35V to 1.15V. The MAX12529 provides a common-mode reference to simplify design and reduce external component count in differential Analog input circuits.
The MAX12529 supports either a single-ended or differential input Clock User-selectable divide-by-two (DIV2) and divide-by-four (DIV4) modes allow for design flexibility and help eliminate the negative effects of Clock jitter. Wide variations in the Clock duty cycle are compensated with the ADC's internal duty-cycle equalizer (DCE).
The MAX12529 features two parallel, 12-bit-wide, CMOS-compatible outputs. The digital output format is pin-selectable to be either two's complement or Gray code. A separate power-supply input for the digital outputs accepts a 1.7V to 3.6V voltage for flexible interfacing with various Logic levels. The MAX12529 is available in a 10mm x 10mm x 0.8mm, 68-pin thin QFN package with exposed paddle (EP), a 597 nd is specified for the extended (-40C to +85C) temperature range.
