THERMISTOR SIGNAL AMPLIFIER FOR TEMPERATURE CONTROL
INA330SBOS260 – NOVEMBER 2002
DESCRIPTIONThe INA330 is a precision amplifier designed for thermoelec-
tric cooler (TEC) control in optical networking applications. It
is optimized for use in 10kΩ thermistor-based temperature
controllers. The INA330 provides thermistor excitation and
generates an output voltage proportional to the difference in
resistances applied to the inputs. It uses only one precision
resistor plus the thermistor, thus providing an alternative to
the traditional bridge circuit. This new topology eliminates the
need for two precision resistors while maintaining excellent
accuracy for temperature control applications.
An excitation voltage is applied to the thermistor (RTHERM)
and precision resistor (RSET), creating currents I1 and I2. The
current conveyor circuit produces an output current, IO, equal
to I1 – I2, which flows through the external gain-setting
resistor. A buffered voltage output proportional to IO is also
provided.
The INA330 offers excellent long-term stability, and very low
1/f noise throughout the life of the product. The low offset
results in a 0.009°C temperature error from –40°C to +85°C.
It comes in MSOP-10 packaging and operates with supply
voltages from +2.7V to +5.5V. It is specified over the indus-
trial temperature range, –40°C to +85°C, with operation from
–40°C to +125°C.
