Introduction

AI Translation

The ADA4530-1 is a femtoampere (10^-15 A) level input bias current operational amplifier suitable for use as an electrometer that also includes an integrated guard buffer. It has an operating voltage range of 4.5 V to 16 Vᵢ, enabling it to operate in conventional 5 V and 10 V single supply systems as well as ±2.5 V and ±5 V dual supply systems. It provides ultralow input bias currents that are production tested at 25 ℃ and at 125 ℃ to ensure the device meets its performance goals in user systems. The integrated guard buffer isolates the input pins from leakage in the printed circuit board (PCB), minimizes board component count, and enables easy system design. The ADA4530-1 also offers low offset voltage, low offset drift, and low voltage and current noise needed for the types of applications that require such low leakages. To maximize the dynamic range of the system, the ADA4530-1 has a rail-to-rail output stage that can typically drive to within 30 mV of the supply rails under a 10 kΩ load. The ADA4530-1 operates over the -40 ℃ to +125 ℃ industrial temperature range and is available in an 8-lead SOIC package.
