GENERAL DESCRIPTION

The AD590 is a 2-terminal integrated circuit temperature trans-

ducer 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 μA/K. Laser trimming of the chip’s thin-film resistors is used

to calibrate the device to 298.2 μA output at 298.2 K (25°C).

The AD590 should be used in any temperature-sensing

application below 150°C 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.

PRODUCT HIGHLIGHTS

1. The AD590 is a calibrated, 2-terminal temperature sensor

requiring only a dc voltage supply (4 V to 30 V). Costly

transmitters, filters, lead wire compensation, and lineari-

zation circuits are all unnecessary in applying the device.

2. State-of-the-art laser trimming at the wafer level in

conjunction with extensive final testing ensures that

AD590 units are easily interchangeable.

In addition to temperature measurement, applications include

temperature compensation or correction of discrete components,

biasing proportional to absolute temperature, flow rate measure-

ment, level detection of fluids and anemometry. The AD590 is

available in die form, making it suitable for hybrid circuits and

fast temperature measurements in protected environments.

3. Superior interface rejection occurs because the output is a

current rather than a voltage. In addition, power

requirements are low (1.5 mW @ 5 V @ 25°C). These

features make the AD590 easy to apply as a remote sensor.

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.

4. The high output impedance (>10 MΩ) provides excellent

rejection of supply voltage drift. For instance, changing the

power supply from 5 V to 10 V results in only a 1 μA

maximum current change, or 1°C equivalent error.

5. The AD590 is electrically durable: it withstands a forward

voltage of up to 44 V and a reverse voltage of 20 V.

Therefore, supply irregularities or pin reversal does not

damage the device.
