Overview
The INA155U/2K5 is a rail-to-rail CMOS instrumentation amplifier manufactured by Texas Instruments. It operates on a single supply voltage ranging from 2.7 V to 5.5 V and consumes 1.7 mA of quiescent current. The device features a 550 kHz bandwidth, a slew rate of 6.5 V/us, and a common-mode rejection ratio of 78 dB. Input bias current is specified at 50 pA with an input offset voltage of 1 mV. Gain options include fixed configurations of 10 V/V and 50 V/V, with a gain error of 0.05%. It is housed in an 8-pin VSSOP package.
Feature Summary
- Rail-to-rail output capability for maximum dynamic range
- CMOS architecture enabling low power consumption
- High input impedance characteristics
Applications
- Battery-powered sensor signal conditioning
- Medical instrumentation front-ends
- Industrial process control systems
Procurement Notes
Verify the specific suffix 'U/2K5' against official manufacturer documentation to confirm reel packaging specifications. Ensure the selected variant matches the required gain configuration and package type for your design. Cross-reference the datasheet revision date to validate parameter accuracy before finalizing procurement orders.
Selection Notes
Select this component when a single-supply operation between 2.7 V and 5.5 V is required. The rail-to-rail output allows for full-scale signal utilization in low-voltage environments. Consider the 50 pA input bias current for high-impedance source applications where minimal loading is critical.
Part Context
This part belongs to the INA155 family of instrumentation amplifiers. The 'U' designation indicates surface-mount packaging, while '/2K5' specifies the tape and reel quantity. It serves as a low-power alternative to bipolar instrumentation amplifiers in portable and battery-operated electronic devices.
Replacement Considerations
Consult official substitution guides for compatible alternatives. Verify pinout compatibility and electrical parameter overlaps before replacing the INA155U/2K5 with other instrumentation amplifier models.
