New Original OPA2340UA 0PA2340UA CMOS Amplifier 2 Circuit Rail-to-Rail 8-SOIC

1. Product Overview
OPA2340UA is a dual-channel, rail-to-rail CMOS operational amplifier launched by Texas Instruments, optimized for low-voltage single-supply operation. Its core advantages include:
1. Rail-to-rail input/output: The input common-mode voltage range covers 500mV below ground potential to 500mV above the positive power supply, and the output voltage swing can reach within 1mV of the power rail under a 100kΩ load.
2. High-speed dynamic response: Gain bandwidth product (GBW) is 5.5MHz, conversion rate (SR) is 6V/μs, and quiescent current is only 750μA/channel.
3. Low distortion and noise: Total harmonic distortion plus noise (THD+N) is as low as 0.0007% (1kHz), and input voltage noise density is 25nV/√Hz.

2. Key performance parameters

3. Core application areas

1. Driving analog-to-digital converters (A/D): Rail-to-rail characteristics ensure complete signal transmission, suitable for data acquisition systems.

2. Audio processing: Low distortion and noise characteristics are suitable for audio signal conditioning, such as microphone preamplification or speaker driving.

3. Sensor interface: Provide high-precision signal conditioning for sensors, such as pressure and temperature sensor outputs.

4. Industrial control: Signal conditioning modules used in PLC (programmable logic controller) or process control.

5. Communication equipment: Support signal buffering and filtering in high-speed data transmission.

4. Package and pin configuration

1. Package: 8-pin SOIC surface mount package is used to support automated assembly.

2. Pin function:

* Input pins (IN+, IN-): Support rail-to-rail input range.

* Output pins (OUT): Rail-to-rail output capability.

* Power pins (V+, V-): Support single power supply (2.5V-5.5V) or dual power supply operation.
