  • Product introduction

The precision INA330 amplifier is designed for thermoelectric cooler (TEC) control in optical network applications.It is optimized for use at 10 km. 10 km. -Thermistor-based temperature controller.Different input resistors are provided for excitation to produce the INA330 proportional output voltage.It uses only one precision resistor plus a thermistor, thus providing an alternative to traditional bridge circuitry.This new topology does not require two precision resistors to maintain good accuracy on temperature control equipment.

An excitation voltage to a thermistor (RTHERM) and a precision resistor (letters) generate a current and a 12 I1 rating.The current conveyor circuit generates output current, I0 I1 class – 12 people, which is equivalent to flowing through an external gain-setting resistor.
