EL5364IUZ-T13 is an integrated, high-performance instrumentation amplifier operating from a single supply and designed for thermocouple, bridge sensor, and other low-level applications. The node uses a single 2.7V to 5.5V power supply and can handle up to ± 12V of dynamic range. Moreover, the amplifier’s low power consumption makes it suitable for battery-powered applications.

The EL5364IUZ-T13 amplifies the differential input by a gain of 100 V/V and features a very low input offset voltage typically 0.25mV. Its CMRR ratio is >100 dB and it exceeds the requirements of instrumentation applications, such as the JESD204B Communication and Data interface standard, railroad and industrial automation. Moreover, the EL5364IUZ-T13 is fully protected from input-output shorts and features an adjustable common-mode voltage that allows it to be interfaced with a wide range of sensors.

In terms of linear amplification, the EL5364IUZ-T13 is a great choice for a wide range of applications, such as instrumentation and sensing, automotive navigation systems, precision monitoring, and industrial control systems. With its wide gain range, wide input dynamic range, low power consumption, and ability to interface to various sensors, this device is an ideal choice for these applications.

The working principle of the EL5364IUZ-T13 is based on the concept of differential input. The differentially-connected transistors together with the resistor network located on the chip form a high-precision input stage. The transistors are bias current-controlled and in combination with the resistor network allow for a precise adjustment of the transistors’ collector current. This allows for an accurate control over the differential input voltage range, which is important for precise control of the differential amplification.

The output stage of the EL5364IUZ-T13 is an inverting amplifier with a gain of 100 V/V. The voltage gain is determined by the value of the resistors connected to the amplifier’s output. The feed-forward compensation used by the device ensures stable operation when the input change is fast. The feedback loop ensures precise control of the gain and reduces the output impedance of the amplifier, which is important for applications where high-precision measurements are required.

In keeping with its use as an instrumentation amplifier, the EL5364IUZ-T13 features excellent linearity performance. Its input offset voltage is typically 0.25mV and the common-mode rejection ratio (CMRR) is >100 dB. This ensures that the output voltage accurately reflects the input voltage. Furthermore, the amplifier is immune to power supply noise and ground potential shifts, further reducing errors in the amplified signal.

The EL5364IUZ-T13 is well-suited for operation from a single supply and can handle up to ± 12V of dynamic range. This allows the device to be used in applications that require a wide input range, such as thermocouples, bridge sensors, and other low-level applications. Additionally, its low power consumption makes it suitable for battery-powered applications.

In summary, the EL5364IUZ-T13 is a powerful yet low-power instrumentation amplifier for a wide range of low-level applications. Its wide gain range, wide input dynamic range, low input offset voltage, high CMRR, and ability to interface with various sensors make it an ideal choice for these applications. Moreover, its low power consumption makes it suitable for battery-powered applications.
