Overview
The MAX1205EMH+ is a 14-bit, monolithic analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This integrated circuit is built on a CMOS process and is capable of conversion rates up to 1 million samples per second (Msps). It features a fully differential, pipelined architecture with digital error correction and a short self-calibration procedure to ensure 14-bit linearity at full sample rates. The device operates from a single +5V supply and includes an on-chip track/hold (T/H) circuit to maintain superb dynamic performance up to the Nyquist frequency.
