CA7004 is a charge amplifier designed for the charge output characteristics of piezoelectric quartz sensors. The weak charge signal output by the piezoelectric sensor is amplified and converted into a voltage signal by a charge amplifier. The CA7004 has four independent charge amplification channels, which can measure charge signals in the range of 1mHz to 10kHz. The automatic zeroing speed of the CA7004 charge amplifier can be as low as 0.01pC/s, which is very conducive to measuring low-frequency weak charge signals.
