LT1491CN#PBF Description

Short technical summary and product information.

The LT1491CN#PBF is a quad operational amplifier from Linear Technology, designed for rail-to-rail input and output operation. It has a gain bandwidth product of 200kHz and a slew rate of 70V/ms, making it suitable for general-purpose signal conditioning and low-frequency applications. The device features low input offset voltage of 1.25mV, low input bias current of 4nA, and a quiescent current of 40µA per amplifier, which is ideal for battery-powered systems.

 

This op-amp includes an enable/shutdown function and built-in compensation, allowing for power savings and simplified design. The common mode rejection ratio is 98dB, and the input voltage noise density is 50nV/√Hz at 1kHz, ensuring good signal integrity in precision circuits. The output current is 25mA, sufficient for driving moderate loads.

 

The LT1491CN#PBF is housed in a PDIP-14 package and is intended for through-hole mounting. It operates over a temperature range of -40°C to +85°C, making it suitable for industrial and commercial environments.
