OPA404KU Information

Description

The Texas Instruments OPA404KU is a quad op-amp (operational amplifier) that offers high precision, low noise, and wide bandwidth in a single-supply operation. It features unity-gain stability, making it suitable for applications where high gain and stability are required. This device is designed for use in industrial instrumentation, power management, current sensing, data acquisition systems, control systems, signal processing, and medical instrumentation. Its low offset voltage and drift make it ideal for precision applications. The OPA404KU has a bandwidth of 5 MHz, making it suitable for high-frequency applications. It also features low noise density, which reduces the impact of external noise on the amplifier's performance. Overall, the OPA404KU is a versatile op-amp that can be used in a wide range of applications where precision and stability are important.

Features

The OPA404KU is a quad op-amp from Texas Instruments, featuring:

  • Single-supply operation
  • Unity-gain stable
  • Low offset voltage (400 µV max)
  • Low offset voltage drift (3 µV/°C max)
  • Low noise density (5.3 nV/√Hz)
  • Wide bandwidth (5 MHz)

These features make it suitable for various applications, including signal conditioning in industrial instrumentation, power management in battery-powered systems, and more.

Package

The package type of OPA404KU is SOP16 (Shrink Small Outline Package, 16 leads).

Pinout

The OPA404KU is a quad op-amp with 16-pin SOP package. The pinout is as follows:

  • Pin 1: VCC (positive supply)
  • Pins 2-5: IN+ (input +)
  • Pins 6-9: OUT (output)
  • Pins 10-13: IN- (input -)
  • Pin 14: VEE (negative supply)
  • Pin 15: COM (common mode input/output)
  • Pin 16: GND (ground)

The OPA404KU is a quad op-amp, meaning it has four individual operational amplifiers on one chip. Each op-amp has its own input and output pins, as well as shared VCC, VEE, and GND pins.

Manufacturer

The manufacturer of the OPA404KU is Texas Instruments (TI). TI is a leading global semiconductor company that designs, manufactures, tests, and sells analog and embedded processing chips. The company was founded in 1930 and is headquartered in Dallas, Texas. TI is a well-known brand in the electronics industry, offering a wide range of products including microcontrollers, digital signal processors (DSPs), amplifiers, sensors, and more.
