| General Description

ZJA3512 family are dual- and quad- precision JFET amplifiers that feature low offset voltage, low input bias current, low input voltage noise and low input current noise. ZJA3512’s offset voltage is guaranteed to be within 75 µV, which is an order of magnitude better than traditional JFET op amps.

The combination of low offset, low noise, and very low input bias current makes these amplifiers especially suitable for high impedance sensor amplification and precise current measurement using shunts. The combination of DC precision, low noise, and fast settling time results in superior accuracy in medical instruments, electronic measurement, and automated test equipment. ZJA3512 family maintain their fast-settling performance even with substantial capacitive loads. Moreover, they do not suffer from output phase reversal when input voltages exceed the maximum common-mode voltage range.

Fast slew rate and excellent stability with capacitive load make ZJA3512 a perfect fit for high performance filters. Low input bias currents, low offset, and low noise result in a wide dynamic range of photodiode amplifier circuits. Low noise and distortion, high output current, and excellent speed make ZJA3512 a great choice for audio applications.

ZJA3512-2 is available in 8-lead narrow SOIC and 8-lead MSOP packages. Both of them are specified over the -40 °C to +125 °C extended industrial temperature range.
