AD8028ARMZ

The AD8028ARMZ is a high-performance, low-power operational amplifier specifically designed for instrumentation, buffer, and other applications of varying demands. With pin-compatible versions and a variety of features such as low noise, low power consumption and low offset voltage, this part is suitable for a wide array of usage areas and cost-effective designs as well.

The AD8028ARMZ is an R-C output style amplifier with a differential input voltage range of ±5V and an output voltage range of ±2.5V to +9V. It achieves an ac gain of one million at 1kHz and can drive up to 10mA current. The AD8028ARMZ was designed for low power consumption with a typical supply current of 69μA. The amplifier also offers a low offset voltage of 2mV and a low noise voltage of 3.2μV peak-to-peak at 1kHz, making it suitable for low-power operation and noise-sensitive applications.

The AD8028ARMZ provides outstanding common-mode rejection ratio (CMRR) of 110db, which ensures excellent rejection of common-mode noise in applications such as audio systems, medical equipment, and measurement systems. Additionally, its single-supply operation enables use in a wide voltage range of input and output signals, such as over-the-air and digital audio signals, without the need for a dual-supply configuration. The combination of all these features makes the AD8028ARMZ ideal for instrumentation, buffer, and other linear amplifier applications.

In terms of its working principle, the AD8028ARMZ provides dc gain for amplification purposes by means of voltage couple devices, or capacitors. These capacitors act as the input stage that converts the signal from DC to AC, which is then amplified and then reconverted back to DC. The capacitors also allow the amplifier to track, or analog signal as it changes over time, while at the same time rejecting any signal that doesn’t change over time. This makes the amplifier ideal for signal conditioning.

The AD8028ARMZ also features an integrated biasing network that provides a stable and low-noise operation. The biasing network ensures that the amplifier reaches its specified performance with a high degree of accuracy and repeatability over a wide range of operating conditions, such as input voltage and temperature. The high-precision performance of the amplifier is further improved by the use of a low-noise, low-offset voltage architecture.

The AD8028ARMZ is a unique linear amplifier suitable for a wide array of applications, from low-power instrumentation to high-performance buffer and audio amplifiers. From its low-power consumption, low noise voltage, to its extremely wide differential input voltage range, the device is an ideal choice for instrumentation, buffer, and other linear amplifier applications.
