4-Channel, 10-Bit, System Monitors with Programmable

Trip Window and SMBus Alert Response

/MAX1362

General Description

Features

The MAX1361/MAX1362 low-power, 10-bit, 4-channel,

analog-to-digital converters (ADCs) feature a digitally

programmable window comparator with an interrupt out-

put for automatic system-monitoring applications. Once

configured, monitor mode automatically asserts an inter-

rupt when any analog input exceeds the programmed

upper or lower thresholds, without interaction to the

host. The MAX1361/MAX1362 respond to the SMBus™

alert, allowing quick identification of the alarming device

on a shared interrupt. A programmable delay between

monitoring intervals lowers power consumption at

reduced monitoring rates.

♦ 4-Channel Single-Ended or 2-Channel Fully

Differential Inputs

♦ Software Programmable Bipolar/Unipolar

Conversions

In addition, the MAX1361/MAX1362 integrate an internal

voltage reference, a clock, and a 1.7MHz, high-speed,

I²C-compatible, 2-wire, serial interface. The optimized

interface allows a maximum conversion rate of 94.4ksps

in normal mode while reading back the conversion

results. Each of the four analog inputs is configurable for

single-ended or fully differential operation and unipolar

or bipolar operation. Two scan modes utilize on-chip

random access memory (RAM) to allow eight conver-

sions of a selected channel or scanning of a group of

channels to reduce interface overhead.

These devices operate from a single 2.7V to 3.6V

(MAX1361) or 4.5V to 5.5V (MAX1362) supply and

require only 436µA at the maximum sampling rate of

150ksps in monitor mode and 670µA at the maximum

sampling rate of 94.4ksps. AutoShutdown™ powers

down the devices between conversions, reducing sup-

ply current to less than 0.5µA when idle.

internal reference or by an externally applied reference

436µA in Monitor Mode (150ksps)

670µA at 94.4ksps

voltage ranging from 1V to V . The MAX1361 features

6µA at 1ksps

a 2.048V internal reference, and the MAX1362 features

a 4.096V internal reference.

0.5µA in Power-Down Mode

♦ Small Package

The MAX1361/MAX1362 are available in a 10-pin

10-Pin µMAX

µMAX package and are specified over the extended

-40°C to +85°C temperature range. For 12-bit applica-

tions, refer to the pin-compatible MAX1363/MAX1364
