INA156EA/250

Overview

The INA156EA/250 is a single-supply, rail-to-rail output CMOS instrumentation amplifier manufactured by Texas Instruments. It operates within a voltage range of 2.7V to 5.5V and supports fixed gains of 10 V/V and 50 V/V. Key electrical specifications include a gain bandwidth product of 550 kHz, a slew rate of 6.5 V/µs, and an input offset voltage of 8 mV. The device features a gain error of 0.03% and is housed in an 8-pin VSSOP package.

Feature Summary

• Rail-to-rail output swing optimized for low-voltage single-supply operation
• CMOS technology designed for low-cost applications
• Fixed gain configurations available at 10 V/V and 50 V/V

Applications

• Low-voltage sensor signal conditioning
• Battery-powered measurement systems
• Single-supply data acquisition circuits

Procurement Notes

Verify the specific suffix (EA/250) against the manufacturer's current datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with the required operating temperature range of -55°C to +125°C. Cross-reference the part number with official Texas Instruments documentation to validate availability and manufacturing status before procurement.

Selection Notes

Select this component when a rail-to-rail output is required from a single supply voltage between 2.7V and 5.5V. It is suitable for applications needing fixed gains of 10 or 50 V/V with moderate bandwidth. Consider the 8-pin VSSOP package for space-constrained designs requiring surface-mount installation.

Part Context

This part belongs to the Texas Instruments INA156 family of instrumentation amplifiers. It is characterized as a low-cost CMOS device intended for single-supply environments. The series provides precision amplification with rail-to-rail output capabilities, distinguishing it from traditional instrumentation amplifiers that require dual supplies or headroom.
