Every component matters in the realm of precision electronics, and when it comes to operational amplifiers (op-amps), the OPA2335AIDR genuinely stands out. This exceptional device, which is part of the OPA334 and OPA335 series, has a number of qualities that make it an excellent choice for a variety of applications. Let’s take a closer look at the features that make the OPA2335AIDR so popular with engineers and designers.

● Low Offset Voltage (5µV max)

The OPA2335AIDR has an extremely low maximum offset voltage of only 5V. This capability is critical in applications where precision and accuracy are critical. Whether you’re measuring small signals or need to have a consistent output, the low offset voltage of this op-amp ensures that your results are as accurate as possible.

● Zero Drift (0.05µV/°C max)

Precision is more than just initial accuracy; it is also about maintaining that accuracy over time and across temperature ranges. The OPA2335AIDR excels in this regard, with a maximum drift of only 0.05V per degree Celsius. This means that your circuit’s performance will remain consistent even when ambient circumstances change, making it ideal for situations where temperature variations are common.

● Low Quiescent Current (285µA)

The OPA2335AIDR shines with its low quiescent current of 285A in battery-powered devices and applications where power efficiency is critical. This low power consumption ensures that your device can run for extended periods of time without fast emptying the battery.

● Single-Supply Operation

The OPA2335AIDR is intended to work with single-supply systems. It is designed for low-voltage operation, with a power supply range of +2.7V to +5.5V (1.35V to 2.75V). Because of this, it is an ideal choice for current electrical equipment that rely on single-supply voltage sources.

● Single and Dual Versions

The OPA2335AIDR’s versatility is a major feature. It is available in single and dual variants, allowing you to select the one that best meets the needs of your application. The OPA2335AIDR has you covered whether you require a single amplifier or a pair for a specific job.

● Shutdown Mode

In many applications, efficiency and power conservation are critical considerations. The shutdown mode on the OPA2335AIDR handles this. Under logic control, the amplifier can be switched from regular operation to a standby current of only 2A. This feature has the potential to greatly increase battery life and minimize overall power consumption.

● MicroSIZE Packages

When space is limited in your design, the OPA2335AIDR’s MicroSIZE packages come in handy. These small packages allow you to conserve space on your PCB while still reaping the benefits of the op-amp’s excellent performance.

Finally, the OPA2335AIDR is a versatile and capable operational amplifier that shines in applications that need precision, stability, and power efficiency. The OPA2335AIDR’s outstanding qualities make it a vital addition to your electronic toolset, whether you’re working on low-power, battery-powered devices or precise measurement systems. Its low offset voltage, minimum drift, and micro-sized packaging bring up a new world of possibilities for engineers and designers looking for high-performance performance in their projects.

Guidelines for Optimal Performance

Consider the following guidelines when using the OPA2335AIDR in your applications:

● Proper Layout

Good layout techniques are critical. For best results, connect a 0.1F capacitor across the supply pins. Design your circuit arrangement with care, avoiding temperature gradients that can induce thermoelectric effects.

● Input Common-Mode Range

Keep in mind that the input common-mode range ranges from (V-) – 0.1V to (V+) – 1.5V. To ensure accurate operation, keep your inputs inside this range.

● Internal Offset Correction

To compensate for offset voltage, the OPA2335AIDR adopts auto-zero methods. Allow it one full auto-zero cycle (about 100s) upon power-up to achieve the required precision.

● Output Swing

This op-amp can swing the output voltage to the negative rail. To ensure good precision, even below the negative rail, use adequate pull-down resistors.
