| General Description
The ZJA3620 is a precision, low-noise instrumentation amplifier that can be used to set the gain range from 1 to 10,000 with a single external resistor.
The ZJA3620 is based on classic three-op-amp structure to provide high common-mode rejection ratio (CMRR) over 93 dB at a gain of 10. This allows it to accurately amplify useful signals in the presence of large external interference, which is a common situation in precision data acquisition, bridge sensor interface, thermocouples, and medical signal acquisition (such as ECG, EEG, etc.).
The ZJA3620 has excellent dc and ac performances. It has low offset voltage of 125 µV max, offset drift of 0.1 µV/°C, and the bias current is 2 nA max, to lower the system calibration cost. The ZJA3620 works well as a preamplifier due to its low input voltage noise of 6.5 nV/ √Hz at 1 kHz, 0.2 µVP-P in the 0.1 Hz to 10 Hz band at the gain of 100. Also, the ZJA3620 is well suited for multiplexed applications with its settling time of 13 µs to 0.01%, slew rate of 1.2 V/µs and bandwidth of 400 kHz at the gain of 10.
The ZJA3620 perform is specified temperature range of -40 °C to +85 °C. Its supply voltage is from ±2.3 V to ±18 V. The ZJA3620 is available in 8-lead SOIC package.
