 The SS490 Series MRL (Miniature Ratiometric Linear) sensors are small, versatile linear Hall effect devices which are operated by the magnetic field from a permanent magnet or an electromagnet.
The ratiometric output voltage is set by the supply voltage and varies in proportion to the strength of the magnetic field.
The integrated circuitry provides increased temperature stability and sensitivity.
Laser trimmed thin film resistors provide high accuracy (null to ± 3%, sensitivity up to ±3%) and temperature compensation.
These linear position sensors have an operating temperature range of -40˚C to +150°C, appropriate for industrial and automotive environments.
They respond to either positive or negative gauss, monitoring either or both magnetic poles.
The quad Hall sensing element minimizes the effects of mechanical or thermal stress on the output.
The positive temperature coefficient of the sensitivity (+0.02%/°C typical) helps compensate for the negative temperature coefficients of low cost magnets, providing a robust design over a wide temperature range.
Rail-to-rail operation (over full voltage range) provides a more usable signal for higher accuracy.
The recent extension to the product line, the SS490B Series, offers costeffective MRL sensing solutions with slightly wider specifications than the SS490 high-performance products.
Like the SS490 Series, the SS490B has a typical sinking or sourcing output of 1.5 mA continuous, uses 7 mA of supply current at 5.0 volts and 25˚C, and provides predictable performance over the full temperature range.
The SS490B Series sensors have wider null and sensitivity tolerances and a wider drift over temperature.
The SS490B Series sensors are a new lower cost product line extension.
They complement the SS490 Series of small size, high accuracy and high performance miniature linear products.

FEATURES
• Small size (.160 x .118 in)
• Power consumption of 7 mA at 5 VDC for energy efficiency
• Single current sinking or current sourcing output
• Linear output for circuit design flexibility
• Built-in thin film resistors are laser trimmed for precise sensitivity and temperature compensation
• Rail-to-rail operation provides more useable signal for higher accuracy
• Temperature range of -40°C to +150°C
• Responds to either positive or negative gauss
• Quad Hall sensing element for stable output

TYPICAL APPLICATIONS
• Current sensing
• Motor control
• Position sensing
• Magnetic code reading
• Rotary encoder
• Ferrous metal detector
• Vibration sensing
• Liquid level sensing
• Weight sensing

GENERAL DESCRIPTION
The AD7148 is designed for use with capacitance sensors imple- menting functions such as buttons, scroll bars, and wheels.
The sensors need only one PCB layer, enabling ultrathin applications. The AD7148 is an integrated capacitance-to-digital converter (CDC) with on-chip environmental calibration. The CDC has eight inputs channeled through a switch matrix to a 16-bit, 250 kHz sigma-delta (Σ-Δ) converter. The CDC is capable of sensing changes in the capacitance of the external sensors and uses this information to register a sensor activation. The external sensors can be arranged as a series of buttons, as a scroll bar or wheel, or as a combination of sensor types. By programming the registers, the user has full control over the CDC setup.
High resolution sensors require minimal software to run on the host processor.
The AD7148 is designed for single electrode capacitance sensors (grounded sensors). There is an active shield output to minimize noise pickup in the sensor. For floating, or two, electrode sensors, use the AD7143.
The AD7148 has on-chip calibration logic to compensate for changes in the ambient environment. The calibration sequence is performed automatically and at continuous intervals as long as the sensors are not touched. This ensures that there are no false or nonregistering touches on the external sensors due to a changing environment. The AD7148 has an I2C®-compatible serial interface, as well as an interrupt output. There is a VDRIVE pin to set the voltage level for the serial interface independent of VCC.
The AD7148 is available in a 16-lead, 4 mm × 4 mm LFCSP and operates from a 2.6 V to 3.6 V supply. The operating current consumption in low power mode is typically 26 μA.

General Description
The MAX6648/MAX6692 are precise, two-channel digital temperature sensors. They accurately measure the temperature of their own die and a remote PN junction, and report the temperature in digital form using a 2-wire serial interface. The remote PN junction is typically the emitter-base junction of a common-collector PNP on a CPU, FPGA, or ASIC. The 2-wire serial interface accepts standard System Management Bus (SMBus)™ write byte, read byte, send byte, and receive byte commands to read the temperature data and to program the alarm thresholds. To enhance system reliability, the MAX6648/MAX6692 include an SMBus timeout. A fault queue prevents the ALERT and OVERT outputs from setting until a fault has been detected one, two, or three consecutive times (programmable). The MAX6648/MAX6692 provide two system alarms: ALERT and OVERT. ALERT asserts when any of four temperature conditions are violated: local overtemperature, remote overtemperature, local undertemperature, or remote undertemperature. OVERT asserts when the temperature rises above the value in either of the two OVERT limit registers. The OVERT output can be used to activate a cooling fan, or to trigger a system shutdown. Measurements can be done autonomously, with the conversion rate programmed by the user, or in a singleshot mode. The adjustable conversion rate allows the user to optimize supply current and temperature update rate to match system needs. Remote accuracy is ±0.8°C maximum error between +25°C and +125°C with no calibration needed. The MAX6648/MAX6692 operate from -55°C to +125°C, and measure temperatures between 0°C and +125°C. The MAX6648 is available in an 8-pin μMAX package, and the MAX6692 is available in 8-pin μMAX and SO packages.
