_______________Ge n e ra l De s c rip t io n

____________________________Fe a t u re s

The MAX1246/MAX1247 12-bit data-acquisition systems

c omb ine a 4-c ha nne l multip le xe r, hig h-b a nd wid th

track/hold, and serial interface with high conversion

speed and low power consumption. The MAX1246 oper-

ates from a single +2.7V to +3.6V supply; the MAX1247

operates from a single +2.7V to +5.25V supply. Both

devices’ analog inputs are software configurable for

unipolar/bipolar and single-ended/differential operation.

♦ 4-Channel Single-Ended or 2-Channel

Differential Inputs

♦ Single-Supply Operation:

+2.7V to +3.6V (MAX1246)

+2.7V to +5.25V (MAX1247)

♦ Internal 2.5V Reference (MAX1246)

♦ Low Power: 1.2mA (133ksps, 3V supply)

54µA (1ksps, 3V supply)

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 MAX1246/MAX1247

use either the internal clock or an external serial-interface

clock to perform successive-approximation analog-to-

digital conversions.

1µA (power-down mode)

♦ SPI/QSPI/Microwire/TMS320-Compatible

4-Wire Serial Interface

♦ Software-Configurable Unipolar or Bipolar Inputs

♦ 16-Pin QSOP Package (same area as 8-pin SO)

The MAX1246 has an internal 2.5V reference, while the

MAX1247 requires an external reference. Both parts have

a re fe re nc e -b uffe r a mp lifie r with a ± 1.5% volta g e -

adjustment range.

______________Ord e rin g In fo rm a t io n

These devices provide a hard-wired SHDN pin and a

s oftwa re -s e le c ta b le p owe r-d own, a nd c a n b e p ro-

grammed to automatically shut down at the end of a con-

version. Accessing the serial interface automatically

powers up the MAX1246/MAX1247, and the quick turn-on

time allows them to be shut down between all conver-

sions. This technique can cut supply current to under

60µA at reduced sampling rates.
