LT1102CJ8

Instrumentation, Op Amps, Buffer Amps Overview

The LT1102CJ8 is a high-speed, precision JFET input instrumentation amplifier manufactured by Analog Devices Inc. It features a fixed gain of 10 or 100 and operates within a supply voltage range of ±18V to ±20V. The device provides a slew rate of 30V/μs, a gain-bandwidth product of 35MHz, and an input bias current of 40pA maximum. It offers a common mode rejection ratio of 97dB and supports an output current of up to ±150mA. Operating temperatures range from 0°C to 70°C.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Precision FET input stage ensuring low offset voltage and minimal input bias current drift
• Integrated fixed gain architecture eliminating the need for external gain-setting resistors
• Robust overdrive recovery and high output drive capability for demanding load conditions

Instrumentation, Op Amps, Buffer Amps Applications

• Fast settling analog signal processing systems
• Multiplexed input data acquisition applications
• Signal amplification from high source impedance sensors such as bridges and photodetectors
• Bridge amplifier configurations requiring lowpass filtering

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'CJ8' corresponds to the commercial temperature grade (0°C to 70°C) and the 8-lead CERDIP package configuration. Confirm that the fixed gain options align with system requirements, as no external resistor adjustment is possible. Ensure supply voltages remain within the specified absolute maximum ratings to prevent permanent damage.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when both high speed and precision are critical, particularly where FET inputs are required to minimize loading on high-impedance sources. The fixed gain options simplify design but limit flexibility compared to adjustable counterparts. Consider the ceramic DIP package for environments requiring hermetic sealing or robust mechanical stability during soldering processes.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the LT1102 family of wideband instrumentation amplifiers known for combining industry-best speed with impressive precision specifications. Unlike many competitive devices, it avoids output offset voltage contributions and maintains stable bias currents across temperature variations. The CJ8 designation specifically identifies the commercial grade variant housed in a hermetic ceramic dual in-line package.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Consult manufacturer documentation for direct substitutes. The N8 PDIP package version may serve as a pin-compatible alternative if hermeticity is not required.
