Product Overview
AD590 is a 2-terminal integrated circuit temperature transducer that produces an output current proportional to absolute temperature. For supply voltages between 4V and 30V, the device acts as a high impedance, constant current regulator passing 1μA/K. Laser trimming of the chip’s thin-film resistors is used to calibrate the device to 298.2μA output at 298.2K (25°C). It 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 this an attractive alternative for many temperature measurement situations. 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.
- Sensor isolation from case
- Superior interface rejection occurs because the output is a current rather than a voltage
- The high output impedance (
10Mohm) provides excellent rejection of supply voltage drift - Electrically durable: it withstands a forward voltage of up to 44V and a reverse voltage of 20V
- Probe-compatible ceramic sensor package
- Current noise is 40pA/√Hz
- Temperature rating range from −55°C to +150°C
- 2-lead FLATPACK package
