MAX1202/MAX1203
EVALUATION KIT AVAILABLE
5V, 8-Channel, Serial, 12-Bit ADCs
with 3V Digital Interface
General Description
The MAX1202/MAX1203 are 12-bit data-acquisition sys-
tems specifically designed for use in applications with
mixed +5V (analog) and +3V (digital) supply voltages.
They operate with a single +5V analog supply or dual ±5V
analog supplies, and combine an 8-channel multiplexer,
high-bandwidth track/hold, and serial interface with high
conversion speed and low power consumption.
A 4-wire serial interface connects directly to SPI/
MICROWIRE® devices without external logic, and a serial
strobe output allows direct connection to TMS320-family
digital signal processors. The MAX1202/MAX1203 use
either the internal clock or an external serial-interface clock
to perform successive approximation analog-to-digital con-
versions. The serial interface operates at up to 2MHz.
The MAX1202 features an internal 4.096V reference,
while the MAX1203 requires an external reference. Both
parts have a reference-buffer amplifier that simplifies gain
trim. They also have a VL pin that is the power supply for
the digital outputs. Output logic levels (3V, 3.3V, or 5V) are
determined by the value of the voltage applied to this pin.
These devices provide a hard-wired SHDN pin and two
software-selectable power-down modes. Accessing the
serial interface automatically powers up the devices. A
quick turn-on time enables the MAX1202/MAX1203 to
be shut down between conversions, allowing the user
to optimize supply currents. By customizing power-down
between conversions, supply current can drop below
10μA at reduced sampling rates.
The MAX1202/MAX1203 are available in 20-pin SSOP
and PDIP packages, and are specified for the commercial
and extended temperature ranges.
