INA101HPG4

Overview

The INA101HPG4 is a very high accuracy instrumentation amplifier manufactured by Texas Instruments. It features a monolithic design with a fixed gain of 10 V/V, eliminating the need for external precision resistors. The device utilizes a 14-pin plastic DIP package (PG). Key electrical characteristics include a maximum input offset voltage of 50 µV and a minimum common-mode rejection ratio of 106 dB. It operates on dual power supplies ranging from ±2 V to ±20 V, with typical operation at ±15 V. The bandwidth is 0.3 MHz, and it supports an operating temperature range of -55°C to +125°C.

Feature Summary

• Monolithic integrated circuit architecture ensures stable performance without requiring external gain-setting components.
• High precision specifications including low input offset voltage and high common-mode rejection ratio for accurate signal conditioning.
• Wide single or dual supply voltage capability allows flexibility in various power environments.

Applications

• Precision data acquisition systems
• Medical instrumentation
• Industrial process control

Procurement Notes

Verify the specific suffix 'H' indicates the extended temperature range (-55°C to +125°C) compared to standard variants. Confirm the 'PG4' suffix denotes lead-free packaging compliant with RoHS standards. Ensure the 14-pin DIP package matches the target PCB footprint. Cross-reference the manufacturer's latest datasheet for any pinout revisions or handling precautions related to the ceramic or plastic die attach technology used in this series.

Selection Notes

Select the INA101HPG4 when a fixed gain of 10 is required alongside high DC accuracy. Consider this part over adjustable instrumentation amplifiers if board space is limited and external resistor matching is undesirable. Evaluate the 0.3 MHz bandwidth against signal frequency requirements. Compare the 106 dB CMRR against system noise floors to ensure adequate common-mode interference rejection.
