General Description
The MAX1080/MAX1081 10-bit analog-to-digital convert-
ers (ADCs) combine an 8-channel analog-input multiplex-
er, high-bandwidth track/hold (T/H), and serial interface
with high conversion speed and low power consumption.
The MAX1080 operates from a single +4.5V to +5.5V sup-
ply; the MAX1081 operates from a single +2.7V to +3.6V
supply. Both devices’ analog inputs are software config-
urable for unipolar/bipolar and single-ended/pseudo-dif-
ferential operation.
The 4-wire serial interface connects directly to
SPI/QSPI and MICROWIRE devices without external
logic. A serial strobe output allows direct connection to
TMS320-family digital signal processors. The MAX1080/
MAX1081 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 VDD1 range may
also be used.
The MAX1080/MAX1081 provide a hard-wired 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. This technique can cut supply current below 100mA
at lower sampling rates.
The MAX1080/MAX1081 are available in a 20-pin TSSOP
package. These devices are higher-speed versions of the
MAX148/MAX149. For more information, refer to the
respective data sheet.
