AMP01GS

Overview

The AMP01GS is a monolithic instrumentation amplifier from Analog Devices, designed for high-precision data acquisition. It features a gain of 0.1 V/V and a 3dB bandwidth of 570 kHz. Key electrical parameters include a slew rate of 4.5 V/us, a common-mode rejection ratio (CMRR) of 125 dB, and an input bias current of 4 nA. The input offset voltage is 20 uV, with a gain-bandwidth product of 26 MHz. It operates on supply voltages between 4.5 V and 18 V, drawing 3 mA of operating current. The device supports output currents up to 100 mA per channel and has a maximum input resistance of 20 GOhms.

Feature Summary

• Monolithic integration combining standard instrumentation amplifier functions with a high-current output stage.
• Maintains stability under high capacitive loads, specifically supporting loads up to 1 μF.
• Designed for high-precision applications requiring low noise and high accuracy.

Applications

• High-precision data acquisition systems
• Industrial instrumentation applications

Procurement Notes

Verify the specific suffix GS against official Analog Devices documentation to confirm package type and temperature range. Confirm availability status as distribution channels may list limited or obsolete stock. Ensure the component matches the required pinout and electrical specifications for the target design before procurement.

Selection Notes

Select this component when a fixed internal gain of 0.1 V/V is acceptable for the signal chain. Consider the high output drive capability if driving heavy capacitive loads directly. Evaluate the 125 dB CMRR requirement against system noise floors. Verify that the through-hole CDIP-18 package fits the mechanical constraints of the PCB layout.

Part Context

The AMP01 series represents a family of precision instrumentation amplifiers known for their robust performance in demanding environments. The AMP01GS variant specifically denotes the commercial grade version housed in a ceramic dual in-line package. This part bridges the gap between standard instrumentation amplifiers and operational amplifiers by offering significant output current capabilities.

Replacement Considerations

Check for AMP01AX or AMP01S variants if different temperature ranges or packaging options are required. Verify compatibility with other members of the AMP01 family for potential drop-in replacements in existing designs.
