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.

In addition, the MAX1361/MAX1362 integrate an internal

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

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.

The full-scale analog-input range is determined by the

internal reference or by an externally applied reference

voltage ranging from 1V to V

a 2.048V internal reference, and the MAX1362 features

a 4.096V internal reference.

The MAX1361/MAX1362 are available in a 10-pin

µMAX

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

tions, refer to the pin-compatible MAX1363/MAX1364

data sheet.
