Linear - Amplifiers - Instrumentation, OP Amps, Buffer Amps

The OPA1611AID (dual precision audio operational amplifier) is a high performance µP audio operational amplifier which offers wide bandwidth, low distortion and low noise. The device is designed for applications such as digital to analog audio converters, digital audio receivers, audio mixing and routing, analog signal processing, and other professional audio applications.

The device features two ultra-low noise, low power, low distortion, high precision operational amplifiers with independently selectable gain, single-ended or differential inputs, and adjustable common-mode range.

Application Field

The OPA1611AID is suitable for a wide range of applications such as audio, video, and data converters, analog signal processing and communication systems, test and measurement, automotive, process control, and industrial automation systems. It can be used as a low-noise, low-power amplification and buffering solution for automotive audio and video systems, including audio systems for cars, trucks, and other vehicles.

The OPA1611AID is also suitable for applications with high dynamic range requirements such as digital audio mixing and routing, equalizers, reverberators, preamplifier stages, and analog to digital and digital to analog converters.

Working Principle

The OPA1611AID is a dual-input, single-output, high-precision, low-noise audio operational amplifier, designed to provide low distortion and low noise performance. It features a wide common-mode input range, wide gain bandwidth, and low power consumption.

The device converts single-ended or differential input signals into a precisely controlled single-ended or differential output. It features two independent, selectable gainsand two independent, distinguished common-mode ranges.

The OPA1611AID also features low input-offset voltage and stable compensation, in order to minimize the effects of external gain variations. The gain bandwidth can be adjusted by selecting the appropriate compensation network. The device can be used with a variety of single-ended and differential amplifiers.

The OPA1611AID is designed to operate over a wide supply voltage range, from 0.4V to 5V. It is also optimized for low-power operation, consuming minimal quiescent current. The device offers minimal distortion, noise, and output-offset voltage, ensuring low-noise, low-distortion performance.
