In this article, we\'ll take a closer look at the LTC1067-50IS#PBF, its key features and applications, and explain its working principle.

LTC1067-50IS#PBF Overview

The LTC1067-50IS#PBF is a single-supply operational amplifier chain with a slew rate of 1V/us and a wide bandwidth of 2.5GHz. It features superior electrical performance, deep 1.5µV/√Hz voltage noise, and a low 2.3mA quiescent current. The LTC1067-50IS#PBF can be used in a variety of different settings, including active filters, data acquisition systems, and low-noise amplifiers.

The LTC1067-50IS#PBF is a 50-amplifier, single-supply operational amplifier chain with an integrated voltage-feedback architecture. It supports four different gain ratios; x1, x2, x4, and x8. It has a common-mode input range of ±1V and a high common-mode rejection ratio of 95dB. The device also includes an active clamp for each amplifier stage, which increases its bandwidth beyond what is achievable with a passive filter.

Applications

The LTC1067-50IS#PBF is primarily used in active filtering applications. Its common-mode rejection ratio of 95dB makes it ideal for high-precision applications where environmental noise can interfere with signal integrity. It can be used in data acquisition systems, low-noise amplifiers, electronic test equipment, and medical instrumentation. The LTC1067-50IS#PBF is also a great choice for frequency-selective circuits, thanks to its wide bandwidth of 2.5GHz.

Working Principle

The LTC1067-50IS#PBF is composed of 50 amplifier stages, each with an active clamp and four gain options (x1, x2, x4, and x8). The active clamp improves the bandwidth of the device by providing a positive feedback loop, which increases the frequency response of the amplifier stage. The gain of each amplifier stage is set using the gain-select pin.

The LTC1067-50IS#PBF utilizes voltage feedback architecture. This means that the output of each amplifier stage is fed back to the input, thereby providing negative feedback, which improves linearity and reduces noise. The LTC1067-50IS#PBF also features a low quiescent current, which helps to maintain high efficiency even when operating at low supply voltages.

Advantages of the LTC1067-50IS#PBF

The LTC1067-50IS#PBF offers a number of advantages over other active filter solutions, including:

• Wide bandwidth of 2.5GHz
