概述

Description

INA216A3YFFR is Texas Instruments’ instrumentation amplifier (in-amp) from the INA216 family. It is designed to amplify small differential sensor voltages while rejecting large common-mode voltages, making it ideal for sensor conditioning (e.g., current-sense shunts, bridges, thermocouples) before an ADC.
Key points:
- 8-pin RoHS VSSOP package, with Tape-and-Reel (YFFR) packaging.
- Provides high input impedance, low offset and drift, and good CMRR for accurate differential amplification.
- Suitable for single- or dual-supply operation and various gain configurations (the A3 variant denotes a specific fixed/gain option within the family).
- Common applications include precision current sensing, bridge sensing, and general sensor conditioning in industrial or automotive electronics.
For exact electrical specs (gain, bandwidth, CMRR, input/output ranges, supply voltage), consult the TI datasheet and product page for INA216A3YFFR.

Features

Here are the typical features you’d expect for TI INA216A3YFFR (instrumentation amplifier family):
- 8-pin package (A3YFFR) suitable for PCB mounting (RoHS-ready, reel-pack option)
- Instrumentation amplifier: differential inputs with high input impedance
- External gain setting via RG for adjustable gain
- Rail-to-rail input and output for single-supply operation
- Low offset voltage and low input-referred noise
- High common-mode rejection ratio (CMRR) and good PSRR
- Wide supply range and capability for single-supply operation
- Reference pin to level-shift the output (baselining)
- Short-circuit protection and robust overload tolerance
- Thermal shutdown/overload protection for reliability
- Low power consumption suitable for battery-powered or portable apps
- Applications: current sensing, shunt amplifiers, sensor conditioning, precision signal conditioning
For exact electrical specs (gain range, offset, noise, CMRR, supply limits, and packaging details), please refer to the TI INA216A3YFFR datasheet.

Package

8-pin VSSOP (VSSOP-8) package; RoHS-compliant; Tape-and-Reel (R) variant.

Pinout

- Pin count: 8 pins (VSSOP-8 / SOIC-8 package)
- Function: Single-channel high-side current-sense amplifier. It amplifies the voltage across a shunt resistor via differential inputs (SH+ and SH−) and provides an output voltage at OUT proportional to the sensed current. Power is provided by V+ and GND, with an optional REF pin to set the output reference.

Manufacturer

- Manufacturer: Texas Instruments (TI)
- What kind of company: Texas Instruments is an American multinational semiconductor company that designs and manufactures analog, mixed-signal, and embedded processing integrated circuits. It is a leading global supplier of analog ICs and related software, headquartered in Dallas, Texas.

Application

INA216A3YFFR is a precision instrumentation amplifier for small differential signals in low-voltage, noisy environments. Common applications:
- Shunt-current sensing and power monitoring (battery, BMS, DC-DC, motor drives)
- Bridge-sensor conditioning (strain gauges, load cells) and RTD/thermocouple sensors
- Industrial data-acquisition front-ends (high CMRR, low offset)
- Automotive/industrial controls and battery-management systems
- Medical instrumentation and portable single-supply measurement systems
