General Description
The MAX1280/MAX1281 12-bit ADCs combine an 8-chan-
nel analog-input multiplexer, high-bandwidth track/hold,
and serial interface with high conversion speed and low
power consumption. The MAX1280 operates from a single
+4.5V to +5.5V supply; the MAX1281 operates from a sin-
gle +2.7V to +3.6V supply. Both devices’ analog inputs
are software configurable for unipolar/bipolar and single-
ended/pseudo-differential operation.
The 4-wire serial interface connects directly to
SPI/QSPI/MICROWIRE devices without external
logic. A serial strobe output allows direct connection to
TMS320-family digital signal processors. The MAX1280/
MAX1281 use an external serial-interface clock to per-
form successive-approximation analog-to-digital con-
versions. Both parts feature an internal +2.5V reference
and a reference-buffer amplifier with a ±1.5% voltage-
adjustment range. An external reference with a 1V to
VDD1 range may also be used.
The MAX1280/MAX1281 provide a hard-wired SHDN
pin and four software-selectable power modes (normal
operation, reduced power, fast power-down, and full
power-down). These devices can be programmed to
automatically shut down at the end of a conversion or to
operate with reduced power. When using the power-
down modes, accessing the serial interface automatical-
ly powers up the devices, and the quick turn-on time
allows them to be powered down between all conver-
sions. This technique can cut supply current to under
100A at reduced sampling rates.
The MAX1280/MAX1281 are available in 20-pin TSSOP
packages. These devices are higher-speed versions of
the MAX146/MAX147 (for more information, see the
respective data sheet).
