INA105KP +BOM

Differential OpAmp Package with 8-pin DIP and ROHS Compliance

INA105KP Information

Description

The Texas Instruments' INA105KP is a precision instrumentation amplifier in an 8-pin PDIP package. This device is designed for high-precision signal processing and amplification, featuring low offset voltage, drift, and input bias current. With a wide supply range of ±2.5V to ±18V, it can be easily integrated into various systems. The INA105KP is well-suited for applications that require accurate signal amplification, such as data acquisition systems, industrial process control, medical instrumentation, audio equipment, and automotive electronic control systems. Its high CMRR (106dB min at 60Hz) ensures the suppression of common-mode noise, resulting in a clean and precise amplified output. In summary, the INA105KP is a reliable and versatile amplifier suitable for various precision instrumentation applications that demand low noise and high accuracy.

Features

The INA105KP features include:

  • Precision instrumentation amplifier
  • Low offset voltage: 50µV max
  • Low drift: 0.1µV/°C max
  • Low input bias current: 1nA max
  • Wide supply range: ±2.5V to ±18V
  • High common-mode rejection ratio (CMRR): 106dB min at 60Hz

These features make it suitable for precision instrumentation applications, such as data acquisition systems, industrial process control, and medical instrumentation, as well as audio equipment, automotive electronic control systems, and low-level sensor amplification circuits.

Package

The package type of the INA105KP is PDIP-8 (Pin Dilectric Package, 8 Pins).

Pinout

The INA105KP is an 8-pin PDIP (Plastic Dual In-Line Package) device. The pinout is as follows:

  • Pin 1: VCC+ (Positive Supply)
  • Pin 2: VCC- (Negative Supply)
  • Pin 3: OUT (Output)
  • Pin 4: IN- (Inverting Input)
  • Pin 5: IN+ (Non-Inverting Input)
  • Pin 6: GND (Ground)
  • Pin 7: COMP (Compensation Pin)
  • Pin 8: VCC- (Negative Supply)

The INA105KP is a precision instrumentation amplifier with differential input and single-ended output. It amplifies the difference between two input signals, rejecting common-mode noise and providing high gain and low noise performance.

Manufacturer

The manufacturer of the INA105KP is Texas Instruments (TI). Texas Instruments 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.
