The PGA204AUE4 is a versatile, low-power and high-performance instrumentation amplifier designed for a variety of applications in a range of settings, including medical, audio, industrial, and automotive. The device features an integrated input stage and adjustable gain from 0 dB to 60 dB and is capable of driving up to 1.6 amps of output current. It also features a unity gain temperature coefficient of 0.0005 °C/°C and can be configured with various gains and offset voltages depending on the application requirement.

The device is designed for a variety of linear amplification applications, including signal conditioning for lab monitoring, medical research, and robotic control systems. It is also suitable for instrumentation applications in audio systems and professional audio equipment. It offers excellent signal-to-noise ratio, low distortion, and superior power efficiency. With its adjustable gain, it is particularly suitable for applications in which linear phase response and low crossover distortion are required.

The PGA204AUE4 is comprised of two core components: the input stage and chip-scale package (CSP). The input stage comprises two differential amplifiers and an adjustable DC offset voltage. The amplifiers convert the input signal into a differential signal and are able to provide a gain of up to 60 dB. The DC offset voltage is adjustable from -20V to +20V and can be used to adjust the gain of the amplifier. The CSP package is a small, highly efficient package designed for superior thermal and electrical performance. It is also RoHS compliant, making it suitable for use in industrial and medical applications.

The device operates on a supply voltage of 2.7V to 5.5V and is available in a range of package sizes, including LCCC, QFN and CSP. The current consumption of the device is typically less than 1 mA. It offers a power supply rejection ratio (PSRR) of 78 dB and an input common mode range (CMR) of ±12V. It also includes an adjustable input bias current of 0.5µA to 1µA and internal compensation for improved stability. The device requires very little external circuitry and is easy to design with.

In addition to its high performance, the PGA204AUE4 is also reliable and robust. It features overvoltage and electrostatic discharge (ESD) protection, and an operating temperature range of -40°C to +135°C. It is also designed to meet safety and regulatory requirements, such as CE and EN55020.

The PGA204AUE4 is ideal for applications in which design size and efficiency are critical. It is a cost-effective solution for high-performance instrumentation and linear amplifier applications, and provides excellent signal-to-noise ratio, low distortion and superior power efficiency. With its adjustable gain and high CMR, it offers a high level of flexibility and can be used in a wide range of systems and applications.
