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.
