INA122 Single Supply Instrumentation Op-Amplifier IC (DIP-8 Package)
The INA122 is a single-supply instrumentation amplifier IC, housed in a DIP-8 package, designed for applications where accurate differential signal amplification is required with the convenience of a single power supply. This IC is ideal for low-power, battery-operated devices, and systems where power efficiency is critical, such as portable sensors, medical instrumentation, and industrial measurement systems. Operating with a wide single-supply voltage range from 2.5V to 36V, the INA122 offers flexibility in system design, particularly in applications where space and power are limited. It provides a high common-mode rejection ratio (CMRR) of 90 dB, ensuring effective rejection of common-mode noise, making it suitable for noisy environments where clean, accurate signal amplification is essential. The INA122 also features a low input offset voltage (typically 250 µV) and low input bias current, ensuring high precision and stable performance over time and temperature variations. The gain of the INA122 is programmable through a single external resistor, allowing the amplifier to be adjusted from 1 to 1000, providing versatility for various signal conditioning needs. The IC's high input impedance and low input bias current make it ideal for interfacing with high-impedance sensors, without loading the signal source.
