General Description

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 mis-

matches 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 out-

put 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.
