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

tems that combine an 8-channel multiplexer, high-band-

width track/hold, and serial interface together with high

conversion speed and ultra-low power consumption.

The devices operate with a single +5V supply or dual

±5V supplies. The analog inputs are software config-

urable for unipolar/bipolar and single-ended/differential

operation.

♦ 8-Channel Single-Ended or 4-Channel

Differential Inputs

♦ Single +5V or ±5V Operation

♦ Low Power: 1.5mA (operating mode)

2µA (power-down mode)

♦ Internal Track/Hold, 133kHz Sampling Rate

♦ Internal 4.096V Reference (MAX186)

♦ SPI-, QSPI-, Microwire-, TMS320-Compatible

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 conver-

sions. The serial interface can operate beyond 4MHz

when the internal clock is used.

4-Wire Serial Interface

♦ Software-Configurable Unipolar or Bipolar Inputs

♦ 20-Pin DIP, SO, SSOP Packages

♦ Evaluation Kit Available

† NOTE: Parts are offered in grades A, B, C and D (grades defined

in Electrical Characteristics). When ordering, please specify grade.

Contact factory for availability of A-grade in SSOP package.

Dice are specified at +25°C, DC parameters only.

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

SO packages, and in a shrink small-outline package

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

For applications that call for a parallel interface, see the

MAX180/MAX181 data sheet. For anti-aliasing filters,

consult the MAX274/MAX275 data sheet.

* * Contact factory for availability and processing to MIL-STD-883.
