General Description
The MAX1282/MAX1283 12-bit analog-to-digital convert-
ers (ADCs) combine a 4-channel analog-input multiplexer,
high-bandwidth track/hold (T/H), and serial interface with
high conversion speed and low power consumption. The
MAX1282 operates from a single +4.5V to +5.5V supply;
the MAX1283 operates from a single +2.7V to +3.6V sup-
ply. 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 MAX1282/
MAX1283 use an external serial-interface clock to perform
successive-approximation analog-to-digital conversions.
The devices feature an internal +2.5V reference and a ref-
erence-buffer amplifier with a ±1.5% voltage-adjustment
range. An external reference with a 1V to VDD range may
also be used.
The MAX1282/MAX1283 provide a hardwired SHDN pin
and four software-selectable power modes (normal opera-
tion, reduced power (REDP), fast power-down (FASTPD),
and full power-down (FULLPD)). 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
automatically powers up the devices, and the quick turn-
on time allows them to be shut down between all conver-
sions.
The MAX1282/MAX1283 are available in 16-pin TSSOP
packages.
