The MAX1363/MAX1364 low-power, 12-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 MAX1363/MAX1364 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 for

reduced monitoring rates.

In addition, the MAX1363/MAX1364 integrate an inter-

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

speed, I

mized interface allows a maximum conversion rate of

94.4ksps in normal mode while reading back the con-

version results. Each of the four analog inputs is config-

urable for single-ended or fully differential operation

and unipolar or bipolar operation. Two scan modes uti-

lize on-chip random access memory (RAM) to allow

eight conversions 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

(MAX1363) or 4.5V to 5.5V (MAX1364) supply and

require only 436µA at the maximum sampling rate of

133ksps 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 1µA 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 MAX1364 features

a 4.096V internal reference.

The MAX1363/MAX1364 are available in a 10-pin

µMAX

(-40°C to +85°C) temperature range. For 10-bit applica-

tions, refer to the pin-compatible MAX1361/MAX1362

data sheet.
