The AD22100 is a monolithic temperature sensor with on-chip signal conditioning. It can be operated over the temperature range -50°C to +150°C, making it ideal for use in numerous HVAC, instrumentation and automotive applications.The signal conditioning eliminates the need for any trimming, buffering or linearization circuitry, greatly simplifying the system design and reducing the overall system cost.The output voltage is proportional to the temperature times the supply voltage (ratiometric). The output swings from 0.25 V at -50°C to +4.75 V at +150°C using a single +5.0 V supply.Due to its ratiometric nature, the AD22100 offers a cost effective solution when interfacing to an analog-to-digital converter. This is accomplished by using the ADC's +5 V power supply as a reference to both the ADC and the AD22100 (See Figure 2 of the datasheet), eliminating the need for and cost of a precision reference to both the ADC and the AD22100 eliminating the need for and cost of a precision reference (see Figure 2).APPLICATIONS HVAC systems System temperature compensation Board level temperature sensing Electronic thermostatsMARKETS Industrial process control Instrumentation Automotive

The AD7417 and AD7418 are 10-bit, 4-channel and single-channelADCs with an on-chip temperature sensor that can operate from asingle 2.7 V to 5.5 V power supply. The devices contain a 15 μssuccessive approximation converter, a 5-channel multiplexer, atemperature sensor, a clock oscillator, a track-and-hold, and areference (2.5 V). The AD7416 is a temperature-monitoring onlydevice in an 8-lead package.The temperature sensor on the parts can be accessed via multiplexerChannel 0. When Channel 0 is selected and a conversionis initiated, the resulting ADC code at the end of the conversiongives a measurement of the ambient temperature (±1°C @ 25°C).On-chip registers can be programmed with high and low temperaturelimits, and an open-drain overtemperature indicator (OTI)output is provided, which becomes active when a programmedlimit is exceeded.A configuration register allows programming of the sense of theOTI output (active high or active low) and its operating mode(comparator or interrupt). A programmable fault queue counterallows the number of out-of-limit measurements that mustoccur before triggering the OTI output to be set to preventspurious triggering of the OTI output in noisy environments.An I2C® compatible serial interface allows the AD7416/AD7417/AD7418 registers to be written to and read back. The threeLSBs of the AD7416/AD7417 serial bus address can be selected,which allows up to eight AD7416/AD7417 devices to be connectedto a single bus.The AD7417 is available in a narrow body, 0.15 inch, 16-lead,small outline package (SOIC) and in a 16-lead, thin shrink,small outline package (TSSOP).

Product Highlights The AD7416/AD7417/AD7418 have an on-chip temperature sensor that allows an accurate measurement of the ambient temperature (±1°C @ 25°C, ±2°C overtemperature) to be made. The measurable temperature range is −40°C to +125°C. An overtemperature indicator is implemented by carrying out a digital comparison of the ADC code for Channel 0 (temperature sensor) with the contents of the on-chip TOTI setpoint register. The AD7417 offers a space-saving, 10-bit analog-to-digital solution with four external voltage input channels, an onchip temperature sensor, an on-chip reference, and a clock oscillator.
