Additional Details:

The AD590 is a 2-terminal integrated circuit temperature sensor that generates an output current directly proportional to absolute temperature. With supply voltages ranging from 4 V to 30 V, it functions as a high-impedance, constant-current source, delivering 1 μA per Kelvin. The chip's thin-film resistors are laser-trimmed to ensure a precise output of 298.2 μA at 298.2 K (25°C).

The AD590 is ideal for temperature-sensing applications below 150°C, offering a cost-effective alternative to traditional electrical temperature sensors. Its monolithic design eliminates the need for additional support circuits like linearization, precision amplifiers, resistance measurement, or cold junction compensation.

Beyond temperature measurement, the AD590 is suitable for applications such as temperature compensation, biasing proportional to absolute temperature, flow rate measurement, fluid level detection, and anemometry. Available in die form, it is well-suited for hybrid circuits and rapid temperature measurement in protected environments.

The AD590 excels in remote sensing applications, thanks to its high-impedance current output, which minimizes the effect of voltage drops over long distances. A well-insulated twisted pair can transmit data over hundreds of feet to the receiving circuitry. Additionally, the AD590 is easy to multiplex, as its current can be switched using a CMOS multiplexer, or the supply voltage can be controlled by a logic gate output.

The TMP05 / TMP06 are monolithic temperature sensors that generate a modulated serial digital output (PWM), which varies in direct proportion to the temperature of the devices. The high period (TH ) of the PWM remains static over all temperatures, while the low period (TL) varies. The B Grade version offers a high temperature accuracy of ±1°C from 0°C to 70°C with excellent transducer linearity. The digital output of the TMP05 / TMP06 is CMOS-/TTL-compatible and is easily interfaced to the serial inputs of most popular microprocessors. The flexible open-drain output of the TMP06 is capable of sinking 5 mA.The TMP05 / TMP06 are specified for operation at supply voltages from 3 V to 5.5 V. Operating at 3.3 V, the supply current is typically 370 μA. The TMP05 / TMP06 are rated for operation over the –40°Cto +150°C temperature range. It is not recommended to operate these devices at temperatures above 125°C for more than a total of 5% (5,000 hours) of the lifetime of the devices. They are packaged in low cost, low area SC-70 and SOT-23 packages.The TMP05 / TMP06 have three modes of operation: continuously converting mode, daisy-chain mode, and one shot mode. A three-state FUNC input determines the mode in which the TMP05 / TMP06 operate.The CONV/IN input pin is used to determine the rate at which the TMP05 / TMP06 measures temperature in continuously converting mode and one shot mode. In daisy-chain mode the, CONV/IN pin operates as the input to the daisy chain.PRODUCT HIGHLIGHTS The TMP05 / TMP06 have an on-chip temperature sensor that allows an accurate measurement of the ambient temperature.
