AD8610AR

AD8610 is a single-channel precision JFET input operational amplifier with ultra-low input bias current. AR refers to the 8-lead narrow SOIC surface mount package, delivered in tube packaging for prototype circuit testing and small-batch production assembly.

This JFET-input op amp features excellent DC precision and low noise performance, optimized for high-impedance sensor signal acquisition, precision buffering and low-frequency measurement applications. It can work with dual bipolar supplies ranging from ±5 V to ±18 V, and also supports single-supply operation.

Input bias current is extremely low at only 1 pA at room temperature, which eliminates voltage errors generated across large-value resistors and guarantees accurate signal readout from piezoelectric transducers, photodiodes and other high-output-impedance sensors. Maximum input offset voltage is 75 μV, paired with low temperature drift to maintain consistent DC accuracy amid ambient temperature variations.

The unity-gain bandwidth reaches 5.5 MHz, with a slew rate of 2.4 V/μs to handle mid-speed transient signals smoothly. Input voltage noise is kept at a low level, effectively improving the signal-to-noise ratio of weak analog signals. Internal on-chip frequency compensation enables stable operation at unity gain and all higher closed-loop gain configurations without external compensation components.

High common-mode rejection ratio and power supply rejection ratio suppress power supply ripple and industrial common-mode electromagnetic interference efficiently. The output stage delivers good load driving capability and stable performance when driving moderate capacitive loads. Total quiescent power consumption is properly controlled for long-duration continuous measurement equipment.

Housed in a compact 8-pin narrow SOIC plastic surface mount package with small footprint, saving PCB layout space for miniaturized precision analog front-end modules. Moisture Sensitivity Level is MSL3; all reflow soldering processes must be completed within 168 hours once the original vacuum packaging is opened. Tube packaging supports manual breadboard debugging, parameter calibration and small-volume trial production conveniently.

Operating temperature range covers −40 °C to +85 °C, enabling reliable long-term operation in laboratory precision measuring instruments, industrial optical detection equipment, portable calibration devices and medical analytical electronics under variable temperature environments. Manufactured using lead-free production processes, the component complies with global RoHS environmental directives. The integrated single-amplifier layout simplifies high-impedance signal conditioning circuits and improves measurement stability for precision acquisition systems.
