TitleSENSOR TEMP ANLG CURR 8-SOIC
Description

ADI’s AD590 temperature transducer produces an output current proportional to absolute temperature. With a wide voltage supply from 4 V to 30 V this transducer is perfect for any temperature sensing applications that require a wide temperature range. The AD590 has been laser trimmed to calibrate 298.2 µA output at 298.2 K (25°C).  The devices are robust and are able to survive forward voltage surges of up to 44 V and reverse voltages of 20 V. The AD590 is ideal for applications that need wide temperature inputs to produce a proportional output current. The device comes a range of packages from 8-SOIC, 4-WDFN to metal cans of TO-5-3 and TO-52-3.

FEATURES

Linear current output: 1 A/K Wide temperature range: to +150C Probe-compatible ceramic sensor package 2-terminal device: voltage in/current out Laser trimmed to 0.5C calibration accuracy (AD590M) Excellent linearity: 0.3C over full range (AD590M) Wide power supply range: 30 V Sensor isolation from case Low cost

The a 2-terminal integrated circuit temperature transducer that produces an output current proportional to absolute temperature. For supply voltages between 4 V and 30 V, the device acts as a high impedance, constant current regulator passing 1 A/K. Laser trimming of the chip's thin-film resistors is used to calibrate the device 298.2 A output K (25C). The AD590 should be used in any temperature-sensing application below 150C in which conventional electrical temperature sensors are currently employed. The inherent low cost of a monolithic integrated circuit combined with the elimination of support circuitry makes the AD590 an attractive alternative for many temperature measurement situations. Linearization circuitry, precision voltage amplifiers, resistance measuring circuitry, and cold junction compensation are not needed in applying the AD590. In addition to temperature measurement, applications include temperature compensation or correction of discrete components, biasing proportional to absolute temperature, flow rate measurement, level detection of fluids and anemometry. The AD590 is available in chip form, making it suitable for hybrid circuits and fast temperature measurements in protected environments. The AD590 is particularly useful in remote sensing applications. The device is insensitive to voltage drops over long lines due to its high impedance current output. Any well-insulated twisted pair is sufficient for operation at hundreds of feet from the receiving circuitry. The output characteristics also make the AD590 easy to multiplex: the current can be switched by a CMOS multiplexer, or the supply voltage can be switched by a logic gate output.

1. The is a calibrated, 2-terminal temperature sensor requiring only a dc voltage supply to 30 V). Costly transmitters, filters, lead wire compensation, and linearization circuits are all unnecessary in applying the device. State-of-the-art laser trimming at the wafer level in conjunction with extensive final testing ensures that AD590 units are easily interchangeable. Superior interface rejection occurs because the output is a current rather than a voltage. In addition, power requirements are low mW 25C). These features make the AD590 easy to apply as a remote sensor. The high output impedance (>10 M) provides excellent rejection of supply voltage drift and ripple. For instance, changing the power supply from 10 V results in only 1 A maximum current change, or 1C equivalent error. The AD590 is electrically durable: it withstands a forward voltage 44 V and a reverse voltage 20 V. Therefore, supply irregularities or pin reversal does not damage the device.
