+5V, Single-Supply, 2.2Msps, 14-Bit Self-Calibrating ADC

Low-Noise and Distortion (81dB SNR at 1.1Msps) 14-Bit 2.2Msps ADC

Please check latest availability status for a specific part variant.


The MAX1201 is a 14-bit, monolithic, analog-to-digital converter (ADC) capable of conversion rates up to 2.2Msps. This integrated circuit, built on a CMOS process, uses a fully differential, pipelined architecture with digital error correction and a short self-calibration procedure that corrects for capacitor and gain mismatches and ensures 14-bit linearity at full sample rates. An on-chip track-and-hold (T/H) maintains superb dynamic performance up to the Nyquist frequency. The MAX1201 operates from a single +5V supply.

The fully differential inputs allow an input swing of ±VREF. A single-ended input is also possible using two operational amplifiers. The reference is also differential with the positive reference (RFPF) typically connected to +4.096V and the negative reference (RFNF) tied to analog ground. Additional sensing pins (RFPS, RFNS) are provided to compensate for any resistive divider action that may occur due to finite internal and external resistances.

The power dissipation is typically only 269mW at +5V and a sampling rate of 2.2Msps. The device employs a CMOS compatible, 14-bit parallel, two's complement output data format. The MAX1201 is available in a 44-pin MQFP package and is specified over the commercial temperature (0°C to +70°C) and extended (-40°C to +85°C) temperature ranges.
