MAX186/MAX188

Low-Power, 8-Channel,

Serial 12-Bit ADCs

General Description

The MAX186/MAX188 are 12-bit data-acquisition sys-

tems that combine an 8-channel multiplexer, high-

bandwidth track/hold, and serial interface together with

high conversion speed and ultra-low power consump-

tion. The devices operate with a single +5V supply or

dual ±5V supplies. The analog inputs are software con-

figurable for unipolar/bipolar and single-ended/differen-

tial operation.

The 4-wire serial interface directly connects to SPI,

QSPI™ and MICROWIRE® devices without external

logic. A serial strobe output allows direct connection to

TMS320 family digital signal processors. The

MAX186/MAX188 use either the internal clock or an

external serial-interface clock to perform successive-

approximation A/D conversions. The serial interface can

operate beyond 4MHz when the internal clock is used.

The MAX186 has an internal 4.096V reference while the

MAX188 requires an external reference. Both parts have

a reference-buffer amplifier that simplifies gain trim .

The MAX186/MAX188 provide a hard-wired

SHDN

and two software-selectable power-down modes.

Accessing the serial interface automatically powers up

the devices, and the quick turn-on time allows the

MAX186/MAX188 to be shut down between every con-

version. Using this technique of powering down

between conversions, supply current can be cut to

under 10µA at reduced sampling rates.

The MAX186/MAX188 are available in 20-pin PDIP and

SO packages, and in a shrink small-outline package

(SSOP), that occupies 30% less area than an 8-pin

PDIP. For applications that call for a parallel interface,

see the MAX180/MAX181 data sheet. For anti-aliasing

filters, consult the MAX274/MAX275 data sheet.
