MAXIM INTEGRATED PRODUCTS  MAX6655MEE+  温度传感器芯片, 双路, 漏极开路, ± 1°C, -55 °C, 125 °C, QSOP, 16 引脚

The 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 MAX6655 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 MAX6655 operates at +5V supply and its second voltage monitor is 3.3V. 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 MAX6655 measure automatically and autonomously with the conversion rate programmable. The adjustable rate allows the user to control the supply current.
