The AD8494/AD8495/AD8496/AD8497 are precision instrumentation amplifiers with thermocouple cold junction compensators on an integrated circuit. They produce a high level (5 mV/°C) output directly from a thermocouple signal by combining an ice point reference with a precalibrated amplifier. They can be used as standalone thermometers or as switched output setpoint controllers using either a fixed or remote setpoint control.The AD8494/AD8495/AD8496/AD8497 can be powered from a single-ended supply (less than 3 V) and can measure temperatures below 0°C by offsetting the reference input. To minimize self-heating, an unloaded AD849x typically operates with a total supply current of 180 μA, but it is also capable of delivering in excess of ±5 mA to a load.The AD8494 and AD8496 are precalibrated by laser wafer trimming to match the characteristics of J type (iron-constantan) thermocouples; the AD8495 and AD8497 are laser trimmed to match the characteristics of K type (chromel-alumel) thermo-couples. See Table 1 on the data sheet for the optimized ambient temperature range of each part.The AD8494/AD8495/AD8496/AD8497 allow a wide variety of supply voltages. With a 5 V single supply, the 5 mV/°C output allows the devices to cover nearly 1000 degrees of a thermo-couple’s temperature range.The AD8494/AD8495/AD8496/AD8497 work with 3 V supplies, allowing them to interface directly to lower supply ADCs. They can also work with supplies as large as 36 V in industrial systems that require a wide common-mode input range.Product Highlights Complete, precision laser wafer trimmed thermocouple signal conditioning system in a single IC package. Flexible pinout provides for operation as a setpoint controller or as a standalone Celsius thermometer. Rugged inputs withstand 4 kV ESD and provide over-voltage protection (OVP) up to VS ± 25 V. Differential inputs reject common-mode noise on the thermocouple leads. Reference pin voltage can be offset to measure 0°C on single supplies. Available in a small, 8-lead MSOP that is fully RoHS compliant.

The ADT7420 is a high accuracy digital temperature sensoroffering breakthrough performance over a wide industrialrange, housed in a 4 mm × 4 mm LFCSP package. It contains aninternal band gap reference, a temperature sensor, and a 16-bitADC to monitor and digitize the temperature to 0.0078°Cresolution. The ADC resolution, by default, is set to 13 bits(0.0625°C). The ADC resolution is a user programmable modethat can be changed through the serial interface.The ADT7420 is guaranteed to operate over supply voltages from2.7 V to 5.5 V. Operating at 3.3 V, the average supply current is typically210 μA. The ADT7420 has a shutdown mode that powersdown the device and offers a shutdown current of typically 2.0 μAat 3.3 V. The ADT7420 is rated for operation over the −40°C to+150°C temperature range.Pin A0 and Pin A1 are available for address selection, giving theADT7420 four possible I2C addresses. The CT pin is an open-drainoutput that becomes active when the temperature exceedsa programmable critical temperature limit. The INT pin is alsoan open-drain output that becomes active when the temperatureexceeds a programmable limit. The INT pin and CT pincan operate in comparator and interrupt event modes.Product Highlights Ease of use, no calibration or correction required by the user. Low power consumption.

The ADXL312 is a small, thin, low power, 3-axis accelerometer with high resolution (13-bit) measurement up to ±12 g. Digital output data is formatted as 16-bit twos complement and is accessible through either a serial port interface (SPI) (3- or 4-wire) or I2C digital interface.The ADXL312 is well suited for car alarm or black box applications. It measures the static acceleration of gravity in tilt-sensing applications, as well as dynamic acceleration resulting from motion or shock. Its high resolution (2.9 mg/LSB) enables resolution of inclination changes of as little as 0.25°. A built-in FIFO facilitates using oversampling techniques to improve resolution to as little as 0.05° of inclination.Several special sensing functions are provided. Activity and inactivity sensing detects the presence or absence of motion and whether the acceleration on any axis exceeds a user-set level. These functions can be mapped to interrupt output pins. An integrated 32 level FIFO can be used to store data to minimize host processor intervention.Low power modes enable intelligent motion-based power management with threshold sensing and active acceleration measurement at extremely low power dissipation.The ADXL312 is supplied in a small, thin 5 mm × 5 mm × 1.45 mm, 32-lead, LFCSP package.APPLICATIONS Car alarm Hill start aid (HSA) Electronic parking brake Data recorder (black box)
