The HJ322A/HJ322B/HJ322C converter amplifiers are low-power, low-drift, high-temperature-resistant precision signal conditioning circuits. They consist of an AC amplifier, a follower, a phase-sensitive demodulator, and an independent operational amplifier. They are manufactured using high-temperature thick-film integrated technology. They feature high integration, lightweight, strong shock and vibration resistance, and flexible usage. They can be widely used in various high-precision tracking systems. HJ322A is a high-temperature low-drift precision signal conditioning circuit with an independent operational amplifier temperature drift coefficient of 0.2μV/℃ and single-ended input. HJ322B is a high-temperature low-power precision signal conditioning circuit with a static power consumption of 54 mW and single-ended input. HJ322C is a high-temperature low-noise precision signal conditioning circuit with an instrumentation amplifier as the input stage, differential input, and gain set by external resistors.
