| General Description
ZJA3018 series high-precision continuous operational amplifiers featuring lower than 10 μV offset voltage, better than 0.5 μV/°C offset voltage drift, 25 pA input bias current and 10 nV/√Hz low noise. These features make them exceptionally suitable for precision signal conditioning, such as precision sensor interface, voltage amplification, current to voltage conversion and filtering. ZJA3018 has single, dual and quad channel versions.
The ZJA3018 series have industry-leading overvoltage protection (OVP) feature: powered by ±15 V, the input protection range can reach -75 V to +60 V, and the smaller input limiting current effectively controls the on-chip heat generation. This feature eliminates the need for external circuitry to prevent amplifier damage, thereby reducing size and costs. It also has over temperature protection (OTP) function.
The ZJA3018 has a low supply current of 500 μA per channel, making them suitable for applications with strict requirements on power consumption or heat management, such as 4-20 mA loop powered instruments.
ZJA3018's input bias current is better than 25 pA, the offset voltage is better than 10 μV, the offset voltage temperature drift is better than 0.5 μV/ºC, and the input range extends to the negative power rail. This makes ZJA3018 very suitable for the sensor signal conditioning, whether in single-supply or dual-supply designs. ZJA3018 can also simplify the entire process of sensor conditioning modules' manufacturing.
The ZJA3018 has a wide power supply voltage range, operating from ±2.25 V to ±18 V for dual-supply operation or 4.5 V to 36 V for single-supply. It further expands its input capabilities to negative rail, making it ideal for a variety of applications.
ZJA3018 series are available in single, dual, and quad configurations:
• ZJA3018-1 (single): SOIC-8 and MSOP-8
• ZJA3018-2 (dual): SOIC-8 and MSOP-8
• ZJA3018-4 (quad): SOIC-14 and TSSOP-14
