MAX1361EUB+

The MAX1361EUB+ is a 4-channel, 10bit, system monitor with programmable trip window and SMBus alert response in 10 pin µMAX package. It features a digitally programmable window comparator with an interrupt output for automatic system-monitoring applications. Once configured, monitor mode automatically asserts an interrupt when any analogue input exceeds the programmed upper or lower thresholds, without interaction to the host. The MAX1361 respond to the SMBus alert, allowing quick identification of alarming device on a shared interrupt. A programmable delay between monitoring intervals lowers power consumption at reduced monitoring rates. It integrates 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. Two scan modes utilize on-chip RAM to allow eight conversions of a selected channel or scanning of a group of channels to reduce interface overhead.

• Supply voltage range is 2.7V to 3.6V
• Operating temperature range from -40°C to 85°C
• Internal reference is 2.048V
• Supply current is 436μA at 150Ksps in monitor mode and 670μA at 94.4Ksps
• AutoShutdown power down reducing supply current to less than 0.5μA when idle
• Full scale analogue i/p range is determined by internal reference/by external reference of 1V to VDD
• 10bit I2C compatible ADC ±1LSB INL, ±1LSB DNL
• 4-channel single ended or 2-channel fully differential inputs
• Software programmable bipolar/unipolar conversions
