Dual-Channel, Platinum RTD-to-Voltage
Signal Conditioner
ELECTRICAL CHARACTERISTICS (continued)
(VCC = 3.0V to 5.5V, resistor connected between RS1+ and RS1- = 560Ω, resistor connected between RS2+ and RS2- = 560Ω,
TA = -40°C to +125°C, unless otherwise noted. Typical values are at VCC = 5.0V, RL = 47kΩ between OUT_ and GND, TA = +25°C.)

Note 1: All parameters are tested at TA = +25°C. Specifications over temperature are guaranteed by design.
Note 2: RTD resistance range is 150Ω to 900Ω for constant excitation current.
Note 3: A typical 200Ω RTD: R(T) = RO[1 + AT + BT2] is referenced for probe temperature-probe resistance relation. The parame-
ters in this section are not tested and are for reference only.
Note 4: RTD resistance is tested only at RRTD = 200Ω, 560Ω, 845Ω. The range is guaranteed by design.
Note 5: Parameters are tested in special test mode.
