General Desc ription
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.
