Product Overview
The INA826 is a Texas Instruments instrumentation amplifier in the Signal_Chain category. It is designed for gain settings from 1 to 1000 using a single external resistor, with the gain defined by G = 1 + 49.4 kΩ / RG. It supports single-supply operation from 3 V to 36 V and dual-supply operation from ±1.5 V to ±18 V, with 200 µA typical supply current stated in the feature summary.
Electrical characteristics include 104 dB minimum common-mode rejection at G = 10, 100 dB minimum CMRR at G = 10 and 5 kHz, and power-supply rejection from 100 dB minimum at G = 1 up to 120 dB minimum at higher gains. The device provides rail-to-rail output, 1 MHz bandwidth at G = 1, and 60 kHz bandwidth at G = 100.
Package options include 8-pin SOIC, 8-pin WSON, and 8-pin VSSOP. The specified free-air operating range is -40°C to +125°C. The input pins are protected up to ±40 V, with input overvoltage current limited to less than 8 mA.

Procurement Notes
When requesting a quote for INA826, buyers should confirm the manufacturer, package or case, required quantity, target date code, compliance documents, packing method, destination country and expected delivery schedule.
If alternatives are acceptable, buyers should share the approved vendor list, required electrical or optical limits, package constraints and qualification requirements. Any alternative part should be reviewed by the buyer's engineering team before production use.
For analog and signal-chain sourcing, supply voltage, bandwidth, accuracy, noise level, package, temperature grade, input/output configuration and qualification requirements should be verified before approval.
