Frequently Asked Questions
What gain does the INA326EA250 provide, and can it be adjusted externally?
The INA326EA250 is configured at a fixed gain of 250 V/V, which eliminates the need for external gain-setting resistors and reduces gain error due to resistor matching, making it immediately suitable for bridge and strain-gauge signal chains with small differential input signals in the millivolt range.
What supply voltage does the INA326EA250 require, and is it compatible with 3.3 V systems?
The INA326EA250 operates from a single supply up to 5.5 V maximum, making it compatible with both 3.3 V and 5 V logic domains. Its rail-to-rail input and output capability ensures the full ADC input range is utilized even at a 3.3 V supply.
How does the 8-pin VSSOP package of the INA326EA250 compare to larger SOIC instrumentation amplifiers in multi-channel sensor boards?
The VSSOP-8 footprint of the INA326EA250 is roughly 50% smaller in PCB area than a standard SOIC-8 package, enabling higher channel density in multi-sensor acquisition boards while maintaining the same 5.5 V rail-to-rail performance and 250 V/V fixed gain.
