General Desc ription
The MAX127/MAX128 are multirange, 12-bit data
acquisition systems (DAS) that require only a single
+5V supply for operation, yet accept signals at their
analog inputs that may span above the power-supply
rail and below ground. These systems provide eight
analog input channels that are independently software
programmable for a variety of ranges: ±10V, ±5V, 0 to
+10V, 0 to +5V for the MAX127; and ±V

REF
/2 for the MAX128. This range
switching increases the effective dynamic range to 14
bits and provides the flexibility to interface 4–20mA,
±12V, and ±15V-powered sensors directly to a single
+5V system. In addition, these converters are fault pro-
tected to ±16.5V; a fault condition on any channel will
not
affect the conversion result of the selected channel.
Other features include a 5MHz bandwidth track/hold,
an 8ksps throughput rate, and the option of an internal
4.096V or external reference.
The MAX127/MAX128 feature a 2-wire, I
2
C-compatible
serial interface that allows communication among multi-
ple devices using SDA and SCL lines.
A hardware shutdown input (
SHDN
) and two software-
programmable power-down modes (standby and full
power-down) are provided for low-current shutdown
between conversions. In standby mode, the reference-
buffer remains active, eliminating start-up delays.
The MAX127/MAX128 are available in 24-pin DIP or
space-saving 28-pin SSOP packages.
