MAX12558 is a MAXIM 14-bit ADC that features fully differential wideband track-and-hold (T/H) inputs, driving internal quantizers. It 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 756mW while delivering a typical 71.7dB signal-to-noise ratio (SNR) performance at a 175MHz input frequency. The T/H input stages accept single-ended or differential inputs up to 400MHz. In addition to low operating power, the MAX12558 features a 330µW power-down mode to conserve power during idle periods.
The MAX12558 is a dual, 3.3 V, 14‑bit analog‑to‑digital converter with fully differential wide‑band track‑and‑hold inputs. It is optimized for low power, small size and high dynamic performance in intermediate‑frequency and baseband sampling applications, delivering a typical 71.7 dB SNR at 175 MHz.
The device operates from a single 3.3 V supply with a power‑down mode of only 330 µW. It supports single‑ended or differential inputs up to 400 MHz, offers a flexible reference structure (internal 2.048 V bandgap or external), and provides two parallel CMOS‑compatible 14‑bit outputs selectable as two’s complement or Gray code. The part is supplied in a 68‑pin thin QFN package (10 mm × 10 mm × 0.8 mm) rated for –40 °C to +85 °C.
