Chandler, Ariz. - Four highly accurate temperature sensors from Andigilog aim specifically at the cellular, personal computer and industrial markets. The aTS20, aTS50, aTS51 analog temperature sensors and the digital aTS75 low-voltage, ultralow-power temperature sensor all claim accuracy of plus/minus 1 degrees C.
The aTS20, a precision CMOS sensor, offers a cost-effective solution for space-constrained apps. Its output voltage ramp has a negative slope of -11.77 millivolts/ degrees C. With a supply voltage of 2.4 V to 6 V, the aTS20 is typically accurate to plus/minus 1 degrees C at 25 degrees C. Reducing the supply voltage to 2.4 V does not change the negative and positive temperature extremes, according to the company. The aTS20 is available in a five-pin SC-70 and a three-pin SOT-23 surface-mount package.
The aTS50 and aTS51 temperature sensors provide high-accuracy, low-power temperature monitoring, with the aTS51 targeted to applications needing high drive current. The device's output voltage ramp is extremely linear and has a slope of 10 mV/ degrees C. Both parts are typically accurate to plus/minus 1 degrees C over a temperature range of -40 degrees C to 125 degrees C and have a typical room temperature accuracy of plus/minus 0.5 degrees C. Both the aTS50 and aTS51 are available in a three-pin SOT-23 surface-mount package.
The aTS75 is a CMOS sensor with a delta-sigma temperature-to-digital converter and an SMbus-compatible serial digital interface. The aTS75 is accurate to plus/minus 1 degrees C over the range of 0 degrees C to 100 degrees C.
In lots of 1,000, the aTS20 is priced at $1.08 each, the aTS50 at $1.18, aTS51 at $1.29 and the aTS75 at $1.43 per unit. Sample packs, cross-reference design information and hardware evaluation kits are available.
