MAX1200
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
±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. 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.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
