INA2332AIPWTG4

Overview

The INA2332AIPWTG4 is a dual-channel instrumentation amplifier from Texas Instruments, housed in a TSSOP-14 package. It operates on a single supply voltage ranging from 2.5 V to 5.5 V with a typical quiescent current of 415 uA per channel. The device features a 2 MHz bandwidth and a slew rate of 5 V/us. Key electrical specifications include a common-mode rejection ratio (CMRR) of 60 dB, an input bias current of 10 pA, and an input offset voltage of 8 mV. The gain error is specified at 0.4%, while the power supply rejection ratio (PSRR) reaches 86.02 dB. It supports an operating temperature range from -55°C to +125°C.

Feature Summary

• Dual-channel architecture providing two independent instrumentation amplifiers in a single compact package.
• Low-power operation designed for battery-powered applications with minimal quiescent current consumption.
• High input impedance characteristics suitable for high-impedance signal sources.

Applications

• Industrial process control sensor interfaces
• Medical equipment signal conditioning
• Data acquisition systems

Procurement Notes

Verify the specific suffix G4 indicates lead-free compliance and RoHS status according to the manufacturer's datasheet. Confirm the TSSOP-14 package dimensions and pinout match your PCB footprint requirements. Ensure the operating temperature range meets your environmental specifications. Cross-reference the exact part number with official Texas Instruments documentation to confirm availability and revision history before finalizing procurement.

Selection Notes

Select this component when a dual-channel solution is required within a limited space constraint. Consider the 2 MHz bandwidth and 5 V/us slew rate for moderate-speed signal processing tasks. Evaluate the 60 dB CMRR against your noise environment requirements. Compare the 415 uA quiescent current against system power budgets. Verify that the 2.5 V to 5.5 V supply range aligns with your available power rails.

Part Context

This part belongs to the INA2332 series of low-power, single-supply instrumentation amplifiers. It shares functional similarities with other devices in the family but differs in packaging and specific suffix designations. The TSSOP-14 package offers a surface-mount solution distinct from through-hole or smaller SOT options found in related product lines.

Replacement Considerations

Check for direct substitutes like the INA2332AIPWR, noting differences in reel quantities. Verify compatibility with other INA2332 variants based on package type and suffix codes. Consult official substitution guides for pin-compatible alternatives if the exact part is unavailable.
