说明The DN405 is a four wire 100 ohm platinum resistance
temperature detector (RTD) signal conditioning circuit that
transforms RTD resistance to a voltage that is proportional
to temperature in °C. This device was designed to operate
with a 100 ohm IEC/DIN-grade Platinum RTD that exhibits
an alpha value of 0.00385!/!/°C. Analog circuit
linearization provides typical accuracy of ±0.5°C over a
temperature range of -100°C to +400°C. The four wire
measurement circuit eliminates the effect of lead resistance
that allows the RTD to be remotely located from the DN405
signal conditioning circuit. The DN405, which operates
from a single supply voltage of +2.7V to +5.5V, draws only
1.3mA of current, making it ideal for portable applications.
The DN405 compensates for the inherent non-linearity of
all platinum RTDs. The output voltage of the device is
directly proportional to the temperature of the RTD. No
digital signal processing is required to make
accurate temperature measurements. The four
wire capability of the DN405 makes it possible to multiplex
several RTDs with one device. This is useful in data
