TI INA128UA SOP-8 Operational Amplifier IC

Operational Amplifier IC Features:

• The multiplier of the operational amplifier is infinite.

• The input resistor of an operational amplifier is infinite and the output impedance is zero.

• The voltage amplification ratio is generally 104~106, and some have reached more than 107.

• Output impedance is very low, generally tens of Ω below.

• Input impedance is very high, generally several hundred kΩ above.

• The integrated operational amplifier circuit is characterized by high voltage amplification, low output impedance and high input impedance.

• The input stage of an operational amplifier is a differential amplifier circuit with high input resistance and the ability to suppress zero drift.

• Intermediate stage mainly for voltage amplification, with high voltage amplification times, generally by the common emitter amplifier circuit.

• The output pole is connected with the load, and has the characteristics of strong load carrying capacity and low output resistance.

• Optimized for high precision system, rich category of innovative operational amplifier product line

Operational Amplifiers (Op-Amps) are analog circuit blocks that take a differential voltage input and produce a single-ended voltage output. They usually have three terminals: two high-impedance inputs and a low-impedance output port. The inverting input is denoted with a minus (-) sign, and the non-inverting input uses a positive (+) sign. Op-Amps are characterized by high gain, high input impedance, and low output impedance. They are called so because they have their origins in analog computers and were mainly used to perform mathematical operations (monolithicpower.com) (electronicshub.org) (en.wikipedia.org) (electronics-tutorials.ws).

Supply Chain System

Quality Testing

Service Guarantees

We guarantee 100% customer satisfaction.

Our experienced sales team and tech support team back our services to satisfy all our customers.

No matter how reliable the surface of the goods looks, we will conduct a series of tests by ourself, or entrust a professional third-party testing organization for testing, such as: Solderability test, to prevent oxidation and ensure the reliability of soldering; Marking permanency test,to prevent refurbished parts.
X-Ray test will also come if needed,etc.

Traceability

Select and identify reliable parts from thousands of suppliers is not easy but GS have accumulated for many years and are constantly updating and improving.

· World's largest source of Shortage and hard to find parts
· One-stop purchasing
· Cost down for supply chain solution
