... C interfaces. The parts come in four versions: the AD7414/AD7415-0, AD7414/AD7415-1, AD7414-2, and AD7414-3. The AD7414/AD7415-0 and AD7414/AD7415-1 versions provide a choice of three different SMBus addresses for each version. All four AD7414 versions give the possibility of eight 2 different I C addresses while the two AD7415 versions allow up to ...

... The measurement modes are compared with a high tempera- ture limit, stored in an 8-bit read/write register. This is applica- ble only to the AD7414, because the AD7415 does not have an ALERT pin and subsequently does not have an overtemperature monitoring function. If the measurement is greater than the high limit, the ALERT pin is activated (if it has already been enabled in the configuration register) ...

... TRANSISTOR SENSING TRANSISTOR Figure 7. Temperature Measurement Technique Figure 7 shows the method the AD7414/AD7415 use to measure the ambient device temperature. To measure ΔV the sensor (substrate transistor) is switched between operating currents of I and N × I. The resulting waveform is passed through a chopper stabilized amplifier that performs the functions of amplification and rectification of the waveform to produce a dc voltage proportional to Δ ...

... Default settings at power-up. CONFIGURATION REGISTER (ADDRESS 0 The configuration register is an 8-bit read/write register that is used to set the operating modes of the AD7414/AD7415. In the AD7414, six of the MSBs are used (D7 to D2) to set the D operating modes (see Table 10). D0 and D1 are used for factory A ...

... D2 Initiate a one-shot temperature conversion if set to 1. The bit status is not stored; thus this bit read. If the AD7414/AD7415 are in power-down mode (D7 = 1), a temperature conversion can still be initiated by the one-shot operation. This involves a write operation to the configuration register and setting the one-shot bit to 1 (D2 = 1), which causes the AD7414/AD7415 to power up, perform a single conversion, and power down again ...

... C addresses available, which are selected by either tying the AS pin to GND float (see Table 4). By giving different addresses for the four versions eight AD7414s or six AD7415s can be connected to a single serial bus, or the addresses can be set to avoid conflicts with other devices on the bus. ...

... SMBus ALERT on the AD7414 is used as an overtemperature indicator. The ALERT pin has an open-drain configuration that allows the ALERT outputs of several AD7414s to be wire-AND’ together when the ALERT pin is active low. Use D4 of the configuration register to set the active polarity of the ALERT output. The power-up default is active low ...

... AD7414/AD7415 packages allows them to be mounted inside sealed metal probes, which provide a safe environment for the devices. SUPPLY DECOUPLING The AD7414/AD7415 should at least be decoupled with a 0.1µF ceramic capacitor between V important if the AD7414/AD7415 are mounted remote from the power supply. ...
