説明
The ISL71590SEH is a temperature-to-current transducer possessing two terminals. It has a high impedance current output that allows it to be insensitive to voltage drops across long lines. When provided a differential voltage between 4V and 33V, the device acts as a constant current regulator that generates a current equal to 1μA/Kelvin (K). The device is specified across the -55°C to +125°C temperature range and with ±1.7°C accuracy without the need for additional circuitry+6. It is also capable of operating up to +150°C. With power requirements as low as 1.5mW (5V at +25°C), they are an ideal choice for remote sensing applications, as any well-insulated twisted pair cable will allow for proper operation. They can be used in several additional applications, including temperature compensation networks, flow rate analysis, anemometry, and biasing proportional to absolute temperature. The high output impedance (>10MΩ) leaves plenty of room for variations in the power supply voltage. The ISL7x590SEH is electrically durable as it can withstand a forward operating voltage of 33V over the full temperature range, both under and without ion beam radiation, and a reverse voltage of -40V. The ISL71590SEH is available in 2 Ld flatpacks and die forms.
