TEXAS INSTRUMENTS LM95234CISD/NOPB Temperature Sensor IC, Voltage, ± 1°C, -40 °C, +125 °C, LLP, 14 Pins

The LM95234CISD is a 11-bit Digital Temperature Sensor with a 2-wire SMBus interface that can very accurately monitor the temperature of four remote diodes as well as its own temperature that includes patent pending remote diode. The four remote diodes can be external devices such as microprocessors, graphics processors or diode-connected 2N3904s. Two LM95234 remote temperature channels have programmable digital filters while the other two emote channels utilize a fault-queue to minimize unwanted TCRIT(bar) events when temperature spikes are encountered. For optimum flexibility and accuracy, each LM95234 channel includes registers for sub-micron process or 2N3904 diode model selection as well as offset correction. The LM95234 includes power saving functions such as: programmable conversion rate, shutdown mode and disabling of unused channels.
