INA826AIDGKR Introduction

The INA826AIDGKR is a precision instrumentation amplifier that Texas Instruments made. It is used a lot in fields where accurate measurements of very low-level signals are needed. This manual will discuss the INA826AIDGKR’s features, specs, and how to use it.

INA826AIDGKR Description

The INA826 is an inexpensive, low-power instrumentation amplifier with a wide operating range. It can get its power from a single source or two separate sources. It doesn’t use much energy and works well. The gain can be changed from one to one thousand with just one external resistor. As G goes above 1, the device stays stable thanks to a small gain drift of about 35 ppm per degree Celsius (maximum). The INA826 has been tuned to have a common-mode rejection ratio of more than 100 dB (G = 10) over a wide frequency range (up to 5 kHz). When G is set to 1, the rejection ratio is more than 84 dB for the whole common-mode input range. This range goes from -1 V all the way up to +1 V.

The rail-to-rail output of the INA826 makes it a good choice for low-voltage applications that use a single 3 V supply or two supplies that add up to 18 V. It also works with power sources with a higher voltage. To protect against input overvoltage, which can be as high as -40 V, more circuitry limits input currents to less than 8 mA. The INA826 comes in several surface-mount packages, such as the standard 8-pin SOIC, the slightly bigger VSSOP, and the small 3-mm 3-mm WSON. The temperature range for each type is between -40 and +125 degrees Celsius.

INA826AIDGKR Features

  • Rejection of the power supply: a minimum of 100 decibels (G = 1).
  • Low offset voltage, with a maximum of 150 V.
  • Protected inputs up to a voltage of 40 V.
  • Output from the rails to the rails.
  • The current drawn from the supply is 200 A.

INA826AIDGKR Detailed Description

A key part of good layout practice is using bypass capacitors placed as close to the device pins as is physically possible. Most of the time, the INA826’s output is connected to the REF terminal, which stands for “output reference.” This connection is grounded. This link must have a low impedance to maintain a high common-mode rejection level. Small resistances of tens of ohms not connected to the REF pin can cause CMRR to drop significantly. Even though you can accept stray resistances of 5 or less when trying to keep a certain CMRR, this is still true.

● Reference Terminal

The output voltage of the INA826 is based on the voltage at the reference pin. In dual-supply operation, the reference pin (pin 6) is often connected to the low-impedance system ground. If you only have one power source, moving the midpoint of the signal to that level can help (for example, 2.5 V in a 5-V supply environment). Connect a voltage source to the REF pin to change the output level so that, for example, the INA826 can drive an ADC that only needs one power source.

Information about how you want to apply The INA826 is a great instrumentation amplifier because it can be used for a wide range of things and uses little power. The INA826 can be used in many low-power, portable applications thanks to its small 8-pin WSON package and low quiescent current (usually 200 A). Due to its input protection circuitry, low maximum gain drift, low offset voltage, and maximum 36-V supply voltage, the INA826 is a great choice for industrial applications.

System Examples

● Precision temperature sensing system:

In this setup, the INA826AIDGKR can boost the signal from a precise temperature sensor like a thermocouple or RTD. The noise voltage at the input is kept to a minimum, and the offset voltage in the amplifier keeps the amplified signal from getting out of sync. The adaptability of this system can help in many fields, from business to medicine.

● Strain gauge measurement system

In this setup, the INA826AIDGKR can be used to boost the signal from a strain gauge, which is a device used to measure very small changes in strain or deformation. The amplifier has a huge range of gain, making it possible to measure low-level signals accurately. The amplifier also does a good job of amplifying the signal because it has low noise and distortion. This technology can be used for many things, such as building design and testing materials.

● Audio signal processing system:

The INA826AIDGKR can be used in this system to boost the signal from a microphone or other audio sensor. The signal is amplified correctly because the amplifier has low noise and distortion. The rail-to-rail input and output allow for a wide range of input signals. This system can be used for many things, like recording audio or boosting the sound in a live setting.

● Industrial control system

The INA826AIDGKR is a signal amplifier that can be included in this system to amplify weak signals from sensors or transducers employed in industrial process control. The low offset voltage and drift allow for precise measurements of weak signals. Low quiescent current consumption and a wide operating supply voltage range make it ideal for power-conserving industrial uses. This system has many applications, from factory automation to surveillance.

Data acquisition and logging system

The INA826AIDGKR can boost weak signals from temperature or strain transducers and other sensors in a system for collecting and logging data. Its wide supply voltage range and rail-to-rail input/output make it suitable for battery-powered or portable data-gathering systems. Its low noise and distortion make it possible to measure small signals confidently. This setup could be used for many things, like keeping an eye on the environment or doing research for school.


In short, the INA826AIDGKR is a highly accurate instrumentation amplifier with a wide range of features and specifications, making it a great choice for many applications. It can be used for many tasks because it has low offset voltage and drift, low noise and distortion, and low quiescent current consumption. It is also easy to add to different systems because of its small size and wide supply voltage range. The INA826AIDGKR is a great choice for a reliable and accurate instrumentation amplifier.
