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
鹵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鈥檚 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擄C to +70擄C) and
extended-industrial (-40擄C to +85擄C) temperature
ranges.
