+5V Single-Supply, 1Msps, 16-Bit

Self-Calibrating ADC

General Description

The MAX1200 16-bit, monolithic, analog-to-digital con-

verter (ADC) is capable of conversion rates up to

1Msps. This CMOS integrated circuit uses a fully differ-

ential, 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 frequen-

cy. 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 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. 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.
