Description

The INA121P is a high-precision instrumentation amplifier from Texas Instruments designed to offer excellent accuracy and low noise in a wide range of applications. This versatile amplifier is suitable for use in medical equipment, industrial process controls, battery-powered devices, and precision data acquisition systems.

Key Features

  • High Accuracy: The INA121P provides a high level of accuracy with a low offset voltage of 50µV (max) and low offset drift of 0.5µV/°C (max), making it ideal for precision measurements.
  • Low Noise: With a low noise density of 9nV/√Hz at 1kHz, the INA121P ensures clean and reliable signals in sensitive applications.
  • Wide Supply Range: The device operates on a single supply ranging from 2.7V to 36V or dual supplies of ±1.35V to ±18V, providing flexibility in various power environments.
  • High Common-Mode Rejection: Featuring a common-mode rejection ratio (CMRR) of 100dB (min) at G=100, the INA121P effectively minimizes the influence of unwanted signals.
  • Adjustable Gain: Gain can be easily set from 1 to 10,000 with a single external resistor, allowing for customization based on specific application requirements.
  • Low Power Consumption: The INA121P is optimized for low power consumption, drawing only 700µA of quiescent current, which is critical for battery-powered and portable applications.

Applications

  • Medical instrumentation
  • Industrial process controls
  • Data acquisition systems
  • Battery-powered equipment
  • Strain gauges and transducers

Package and Reliability

The INA121P is offered in an 8-pin plastic DIP package, providing a compact solution that is both robust and reliable. Texas Instruments ensures high-quality standards, and the INA121P is no exception, offering long-term stability and performance for critical applications.
