_______________General Description
The MAX1204 is a 10-bit data-acquisition system
specifically designed for use in applications with mixed
+5V (analog) and +3V (digital) supply voltages. It oper-
ates with a single +5V analog supply or dual ±5V ana-
log supplies, and combines an 8-channel multiplexer,
internal track/hold, and serial interface with high con-
version 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 MAX1204
uses either the internal clock or an external serial-inter-
face clock to perform successive-approximation ana-
log-to-digital conversions. The serial interface operates
at up to 2MHz.
The MAX1204 features an internal 4.096V reference and
a reference-buffer amplifier that simplifies gain trim. It
also has a VL pin that supplies power to the digital out-
puts. Output logic levels (3V, 3.3V, or 5V) are determined
by the value of the voltage applied to this pin.
A hard-wired SHDN pin and two software-selectable
power-down modes are provided. Accessing the serial
interface automatically powers up the device. A quick
turn-on time allows the MAX1204 to be shut down
between conversions, enabling the user to optimize
supply currents. By customizing power-down between
conversions, supply current can drop below 10A at
reduced sampling rates.
The MAX1204 is available in 20-pin SSOP and PDIP
packages, and is specified for the commercial and
extended temperature ranges.
