The OPA2330AIDGKR is an ultra-low noise amplifier and low distortion instrumentation amplifier. It is used in applications across a wide range of industries, including audio, medical, IoT, and automotive. The device provides high performance and precise data measurements while reducing power consumption.

OPA2330AIDGKR is a low-noise, versatile, low-distortion instrumentation amplifier designed for use in many demanding applications. It is used in audio amplifiers, medical instrumentation systems, Internet of Things (IoT) devices, autonomous vehicles, and other applications requiring precise data measurements.

The OPA2330AIDGKR is a fully-differential input, low-noise amplifier that supports gains of up to 100 dB, with a total harmonic distortion (THD) of less than 0.0005% at 1 kHz and a signal-to-noise ratio (SNR) of more than 84 dB. It features a wide power supply range of +2.7V to +16V and offers low output offset voltage of 0.1mV or less. The device’s low current consumption of 55μA (typical) makes it suitable for powering low-power sensors, transducers, and other instruments.

From a technical standpoint, the OPA2330AIDGKR utilizes a differential pipeline topology, providing a wide range of gain adjustment with exceptionally low noise. Electronically balanced, the device supports inputs from true single-ended, pseudo-single ended, and differential sources. It also provides superior common-mode rejection (CMRR) and low power supply rejection (PSRR).

The device’s primary feature is its ultra-low noise performance. It offers a wide bandwidth with a THD of less than 0.005% at 1 kHz, which allows it to achieve extremely low noise levels. This enables more accurate signal measurements and improved dynamic range compared to devices with higher THD levels. Additionally, it supports a low noise floor, with a maximum input noise of less than 1.8 nV/√Hz and an output noise of just 2.9 μVrms.

The device also features an integrated shutdown mode, which can be triggered directly from the input signal or an external control signal. This allows for very low power consumption and fast turn-off, making it ideal for use in battery-powered applications. Additionally, the OPA2330AIDGKR is designed with a thermal overload protection feature which helps protect the device from excessive current.

The OPA2330AIDGKR is an excellent choice for applications requiring precise data measurements with low-noise performance, such as audio amplifiers, medical instrumentation systems, IoT, and autonomous vehicles. Its wide power supply range, low THD performance, low offset voltage, and integrated low-power shutdown mode make it an attractive option for a variety of demanding applications.
