General Description

The MAX1205 is a 14-bit, monolithic, analog-to-digital

converter (ADC) capable of conversion rates up to

1Msps. This integrated circuit, built on a CMOS pro-

cess, 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/hold (T/H) maintains superb

dynamic performance up to the Nyquist frequency. The

MAX1205 operates from a single +5V supply.

The fully differential inputs allow an input swing of

±V

REF

. The reference is also differential, with the posi-

tive reference (RFPF) typically connected to +4.096V

and the negative reference (RFNF) connected to ana-

log ground. Additional sensing pins (RFPS, RFNS) are

provided to compensate for any resistive-divider action

that may occur due to finite internal and external resis-

tances in the reference traces and the on-chip resis-

tance of the reference pins. A single-ended input is

also possible using two operational amplifiers.

The power dissipation is typically 257mW at +5V, at a

sampling rate of 1Msps. The device employs a CMOS-

compatible, 14-bit parallel, two’s complement output

data format. For higher sampling rates, the MAX1201 is

a 2.2Msps pin-compatible upgrade to the MAX1205.

The MAX1205 is available in an MQFP package, and

operates over the commercial (0°C to +70°C) and the

extended (-40°C to +85°C) temperature ranges.
