General Description
The MAX1202/MAX1203 are 12-bit data-acquisition
systems specifically designed for use in applications
with mixed +5V (analog) and +3V (digital) supply volt-
ages. 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 inter-
face with high conversion speed and low power con-
sumption.
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 conversions. 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 10A at reduced sampling rates.
The MAX1202/MAX1203 are available in 20-pin SSOP
and DIP packages, and are specified for the commer-
cial, extended, and military temperature ranges.
