The MAX1206 is a 3.3V, 12-bit analog-to-digital converter (ADC) featuring a fully differential wideband track-and-hold (T/H) input, driving the internal quantizer. The MAX1206 is optimized for low power, small size, and high dynamic performance. This ADC operates from a single 3.0V to 3.6V supply, consuming only 159mW, while delivering a typical signal-to-noise ratio (SNR) performance of 68.6dB at a 20MHz input frequency. The T/H-driven input stage accepts single-ended or differential inputs. In addition to low operating power, the MAX1206 features a 0.15mW power-down mode to conserve power during idle periods. A flexible reference structure allows the MAX1206 to use its internal precision bandgap reference or accept an externally applied reference. A common-mode reference is provided to simplify design and reduce external component count in differential analog input circuits. The MAX1206 supports both a single-ended and differential input clock drive. Wide variations in the clock duty cycle are compensated with the ADC's internal duty-cycle equalizer. The MAX1206 features parallel, CMOS-compatible outputs. 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 power input for the digital outputs accepts a voltage from 1.7V to 3.6V for flexible interfacing with various logic levels.
The MAX1206 is a 3.3 V, 12‑bit analog‑to‑digital converter featuring a fully differential track‑and‑hold input and CMOS‑compatible outputs. It operates from a single 3.0 V to 3.6 V supply and includes a low‑power 0.15 mW power‑down mode.
The device is offered in a 40‑pin thin QFN package (6 mm × 6 mm × 0.8 mm) and is rated for an extended industrial temperature range of –40 °C to +85 °C. Applications include communication receivers, ultrasound, medical imaging, and low‑power data acquisition.
