概述

Description

INA819IDGKR is a Texas Instruments instrumentation amplifier designed for precision differential signal amplification, commonly used in current-sensing and sensor interfaces.
Key points:
- Optimized for low offset, low drift, low noise, and high common-mode rejection.
- Suitable for measuring small differential voltages across shunts or sensors with a wide supply range.
- The IDGKR suffix denotes the specific 8-pin package/ordering option (lead-free, RoHS-compliant packaging).
For exact electrical specs (gain, input range, bandwidth), pinout, and package details, consult the INA819 datasheet and TI packaging guide.

Features

Here are the key features of the INA819IDGKR (high-level, concise):
- Precision instrumentation amplifier for low-level differential signals
- Low input offset voltage and low offset drift; low input bias current
- High common-mode rejection ratio (CMRR) and good PSRR
- Wide supply range with single-supply operation
- Rail-to-rail output (usable swing close to rails)
- External gain setting via resistor network (flexible gain)
- Fast bandwidth and settling time for dynamic signals
-Low power consumption
- 8-pin package (DGK/R variant suitable for compact designs)
- Industrial temperature range support
For exact electrical specs (typical/limit values, gains, bandwidth, and temperature range), please consult the TI INA819 datasheet.

Package

8-pin SOIC package (SOIC-8), RoHS-compliant, shipped in Tape & Reel.

Pinout

8 pins. Function: TI INA819IDGKR is a high-precision current-sense amplifier. It takes the differential voltage across a shunt resistor (input pins) and, with a gain, produces a single-ended output voltage proportional to the sensed current. It also provides a reference/offset pin and standard power/ground pins, making it suitable for accurate current measurement in power-management applications.

Manufacturer

Manufacturer: Texas Instruments (TI).
Kind of company: TI is an American multinational semiconductor company, headquartered in Dallas, Texas, that designs and manufactures analog and embedded processing integrated circuits and other semiconductor devices.

Application

INA819IDGKR is a high-precision instrumentation amplifier for differential signal conditioning in high common-mode environments. Common application areas:
- High-side/low-side current sensing with shunts in automotive and industrial power stages
- Motor control and drive electronics
- Power-supply and DC-DC converter sensing
- Energy metering and battery-management systems
- Transducer/interface conditioning (bridge sensors, RTDs)
- Data-acquisition front ends needing low noise and high CMRR
