ADA4530-1 (3)

Ultra-Low Input Bias Current: The ADA4530-1 features an exceptionally low input bias current of ±20 fA at 25°C, ensuring minimal current leakage. This makes it ideal for high-precision applications such as picoammeters, coulombmeters, and photodiode transimpedance amplifiers, where even tiny currents can significantly affect accuracy.
Integrated Guard Buffer: The amplifier includes an integrated guard buffer with a maximum offset of 100 µV, which helps reduce leakage currents and improves signal integrity. This feature is particularly beneficial in applications involving high-impedance sensors, such as chemical or capacitive sensors, where maintaining signal fidelity is critical.
Wide Supply Voltage Range: With an operating voltage range of 4.5 V to 16 V (±2.25 V to ±8 V), the ADA4530-1 is versatile and can be used in both single and dual supply systems. This flexibility allows it to be integrated into a wide variety of designs, from portable devices to industrial instrumentation.
Low Offset Voltage and Drift: The amplifier offers a low offset voltage of 50 µV maximum and a drift of ±0.5 µV/°C maximum, ensuring high accuracy over a wide temperature range. This is crucial for precision applications like laboratory instrumentation and analytical systems, where stable performance is required.
High Bandwidth and Slew Rate: With a unity-gain bandwidth of 2 MHz and a slew rate of 1.4 V/µs, the ADA4530-1 delivers fast signal response and high-speed performance. This makes it suitable for applications requiring rapid signal processing, such as spectrophotometers and mass spectrometers.
