LT6017IDJC#TRPBF

Instrumentation, Op Amps, Buffer Amps Overview

The LT6017IDJC#TRPBF is a quad precision operational amplifier manufactured by Analog Devices Inc. It features rail-to-rail input and output capabilities with an Over-The-Top input stage allowing common mode voltages up to V+ + 76V. The device operates on supplies from 3V to 50V, drawing 315µA per amplifier. Key electrical parameters include a gain bandwidth product of 3.2MHz, a slew rate of 0.75V/µs, and a maximum input offset voltage of ±50µV. It provides reverse battery protection to -50V and unity-gain stability with capacitive loads up to 200pF.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Over-The-Top input stage enables operation with input common mode voltages extending up to 76V above the negative supply, independent of the positive supply rail.
• Reverse battery protection allows the device to withstand negative supply voltages down to -50V without damage or excessive current draw.
• Rail-to-rail input and output stages ensure full signal swing capability across the entire supply range.
• Integrated phase reversal protection prevents output polarity inversion when input signals fall below the negative supply rail.

Instrumentation, Op Amps, Buffer Amps Applications

• High side or low side current sensing
• Battery and power supply monitoring
• 4mA to 20mA transmitters
• High voltage data acquisition systems

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific temperature grade suffix (ID for industrial, HD for extended, MP for military) matches the required operating range. Confirm the DJC package designation corresponds to the 22-lead DFN form factor. Ensure the TRPBF suffix indicates tape and reel packaging with lead-free finish. Cross-reference the manufacturer part number against official Analog Devices documentation to confirm authenticity and revision status.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for applications requiring high voltage tolerance and precision in harsh environments. The quad configuration offers space efficiency compared to single or dual variants. Consider the trade-off between increased bias current in Over-The-Top mode versus the benefit of extended input voltage range. Verify that the 315µA quiescent current meets system power constraints.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the LT6015/LT6016/LT6017 family of low power, precision operational amplifiers. While the LT6015 is a single channel and the LT6016 is a dual channel, the LT6017 integrates four amplifiers into a single 22-lead DFN package. All variants share identical electrical characteristics and pinout compatibility regarding the amplifier functions.

Instrumentation, Op Amps, Buffer Amps FAQ

How does the input bias current change during Over-The-Top operation?

In normal operation, the input bias current is typically under ±2nA. When the common mode voltage exceeds the positive supply rail, the internal circuitry transitions to a common base configuration, causing the input bias current to increase to approximately 14µA.

What is the differential input impedance in Over-The-Top mode?

The differential input impedance decreases significantly from 1MΩ in normal operation to approximately 3.7kΩ when operating in the Over-The-Top region due to the common base input stage configuration.
