OPA2140AIDR Description

Short technical summary and product information.

The Texas Instruments OPA2140AIDR is a dual-channel, JFET input operational amplifier designed for precision applications. It boasts a low noise density of 5.1 nV/√Hz and very-low 1/f noise of 250 nV PP from 0.1 Hz to 10 Hz. The amplifier provides a unity-gain bandwidth of 11 MHz and a slew rate of 20 V/µs.

With a very-low offset voltage of 120 µV and an offset drift of 1 µV/°C maximum, the OPA2140AIDR ensures stable performance. It features low input bias current of 10 pA maximum. The device supports single-supply operation from 4.5 V to 36 V and dual-supply operation from ±2.25 V to ±18 V.

This operational amplifier is available in an industry-standard 8-pin SOIC package, suitable for surface mount applications. The operating temperature range is -40°C to 125°C, making it suitable for a wide range of environmental conditions.
