A difference charge amplifier comprises a temperature sencor, a temperature selector, a thermoelectric module being in thermal contact with two radiators, a temperature stabilizator having voltage bipolar output. The temperature sensor and one radiator are located inside a heat-insulation casing; second radiator is located outside of the heat-insulation casing. Temperature sencor output is connected to first input of the temperature stabilizator having voltage bipolar output. To second input of which, temperature selector output is connected. Output of the temperature stabilizer having voltage bipolar output is connected to thermoelectric module output, second output being grounded. |
