5V Single-Supply, 1Msps, 16-Bit Self-Calibrating ADC

The MAX1200 16-bit, monolithic, analog-to-digital converter (ADC) is capable of conversion rates up to 1Msps. This CMOS integrated circuit uses a fully differential, pipelined architecture with digital error correction and a short self-calibration to ensure 16-bit linearity at full sample rates. An on-chip track/hold (T/H) maintains superb dynamic performance up to the Nyquist frequency. The MAX1200 operates from a single +5V supply.

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

Power dissipation is typically only 273mW at +5V, at a sampling rate of 1Msps. The device employs a CMOS-compatible, 16-bit parallel, two's complement output data format. For a higher sampling speed (up to 2.2Msps) but lower resolution (14-bit), select the MAX1201, a pin-compatible version of the MAX1200.

The MAX1200 is available in an MQFP package and operates over the commercial (0°C to +70°C) and extended-industrial (-40°C to +85°C) temperature ranges.
