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

____________________________Fe a t u re s

The MAX1248/MAX1249 10-bit data-acquisition sys-

tems combine a 4-channel multiplexer, high-bandwidth

track/hold, and serial interface with high conversion

speed and low power consumption. They operate from

a s ing le +2.7V to +5.25V s up p ly, a nd the ir a na log

inputs are software configurable for unipolar/bipolar

and single-ended/differential operation.

♦ 4-Channel Single-Ended or 2-Channel

Differential Inputs

♦ Single +2.7V to +5.25V Operation

♦ Internal 2.5V Reference (MAX1248)

♦ 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-fa mily d ig ita l s ig na l p roc e s s ors . The

MAX1248/MAX1249 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 MAX1248 has an internal 2.5V reference, while the

MAX1249 requires an external reference. Both parts

have a reference-buffer amplifier with a ±1.5% voltage

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

conversion. Accessing the serial interface automatically

p owe rs up the MAX1248/MAX1249, a nd the q uic k

turn-on time allows them to be shut down between all

conversions. This technique can cut supply current to

under 60µA at reduced sampling rates.
