A flexible reference structure allows the MAX12527 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 MAX12527 provides a common-mode reference to simplify design and reduce external component count in differential analog input circuits.
The MAX12527 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 MAX12527 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 MAX12527 is available in a 10mm x 10mm x 0.8mm, 68-pin thin QFN package with exposed paddle (EP), and is specified for the extended (-40°C to +85°C) temperature range.
For a 14-bit, pin-compatible version of this ADC, refer to the MAX12557 data sheet.
