INA216A3YFFR

The INA216A3YFFR is a Texas Instruments instrumentation amplifier (part of the INA216 family) designed to boost small differential sensor signals with high common-mode rejection. It uses a three-op-amp instrumentation amp core and offers adjustable gain via an external RG, enabling precise amplification for sensors such as shunt resistors, bridge sensors, and thermocouples. It supports single- or dual-supply operation and provides a rail-to-rail output limited by the supply. The A3YFFR suffix denotes a specific temperature/grade and packaging/reel option. Typical applications include precision current sensing, bridge-sensor front ends, and ADC input conditioning. For exact electrical specs (gain range, input common-mode range, supply voltage, output swing) and packaging details, refer to the TI INA216A3 datasheet and product page.

Equivalents depend on the required specs (gain, input range, supply). Closest TI substitutes are other members of the INA216 family in different packages, e.g. INA216A3IDR or INA216A3Q1. For non‑TI options with similar performance, consider Analog Devices AD8421/AD8422 or AD623, and Linear Technology (Analog Devices) LTC2050/LTC2057 family of instrumentation amplifiers. For exact cross‑reference, use a distributor’s cross-reference tool.

INA216A3YFFR features (concise):
- Precision instrumentation amplifier with high CMRR for accurate differential measurements
- Wide supply range with suitable single-supply operation
- Programmable gain via external feedback network
- Very low input-offset voltage and low input-bias currents for accuracy
- Low-noise performance and high input impedance
- Robust protection: input protection, short-circuit/overload handling
- Fast settling for dynamic signals
- Suitable for current-sense and shunt-monitoring applications
- Low power consumption and compact RoHS-compliant package (A3YFFR)

- Pin count: 8 pins
- Function: Instrumentation amplifier / current-sense monitor. It amplifies the differential voltage across a shunt resistor and provides a single-ended output (with a reference pin for offset), used for precise current measurement in power-management applications.

The INA216A3YFFR is manufactured by Texas Instruments (TI). TI is an American multinational semiconductor company that designs and manufactures integrated circuits and related software, specializing in analog, mixed-signal, and embedded processing products.
