MAX6656MEE+ (MAXIM INTEGRATED PRODUCTS)

The MAX6656MEE+ is a dual remote/local temperature sensors and four channel voltage monitor in 16 pin QSOP package. The digital thermometer reports the temperature of two remote sensors and its own die temperature. The remote sensors are diode-connected transistors. The MAX6656 also measure its own supply voltage and three external voltages with 8bit resolution. Each voltage input's sensitivity is set to give approximately 3/4-scale output code when the input voltage is at its nominal value. The MAX6656 operates on a +3.3V supply and its second voltage monitor is 5V. The 2 wire serial interface accepts standard SMBus write byte, read byte, send byte and receive byte commands to program the alarm thresholds and to read data. It also provide SMBus alert response and timeout functions. The MAX6656 measure automatically and autonomously with the conversion rate programmable. The adjustable rate allows the user to control the supply current.
