The MAX1361/MAX1362 4-channel ADCs use succes-
sive-approximation conversion techniques and fully dif-
ferential input track/hold (T/H) circuitry to capture and
convert analog signals to a serial 10-bit digital output.
The MAX1361/MAX1362 feature a monitor mode with
programmable trip thresholds and window comparator.
The monitor function asserts an interrupt when any
channel violates the programmed upper or lower
thresholds. SMBus alert response allows the host
microcontroller (µC) to quickly identify which device
caused the interrupt. A programmable delay between
monitoring intervals lowers power consumption at lower
monitor rates.
The MAX1361/MAX1362 integrate an internal voltage
reference and clock. The software configures the ana-
log inputs for unipolar/bipolar and single-ended/fully
differential operation. Integrated first-in/first-out (FIFO)
allows conversion of all channels, or eight conversions
