LT1058ACN

Instrumentation, Op Amps, Buffer Amps Overview

The LT1058ACN is a quad JFET input precision high-speed operational amplifier in a 14-lead PDIP package. It features a typical slew rate of 14V/µs and a gain-bandwidth product of 5MHz. The maximum input offset voltage is 600µV with a drift of up to 7µV/°C. Input bias current is typically 75pA at 70°C, and voltage noise density is 13nV/√Hz at 1kHz. It operates on supply voltages from ±8V to ±20V within the 0°C to 70°C temperature range.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Combines high speed performance with precision specifications for accurate signal processing
• Offers significant accuracy improvement over existing JFET input quad operational amplifiers
• Replaces four single precision JFET input op amps while saving board space and power dissipation
• Includes phase reversal protection circuitry to prevent output lock-up in servo systems

Instrumentation, Op Amps, Buffer Amps Applications

• Precision, high-speed instrumentation
• Fast, precision sample-and-hold circuits
• Logarithmic amplifiers
• D/A output amplifiers
• Photodiode amplifiers

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific AC grade suffix matches the required offset voltage and temperature range specifications. Confirm the N package designation corresponds to the 14-lead plastic DIP form factor. Ensure compatibility with LF347, LF444, TL074, and TL084 sockets if direct replacement is intended. Check for lead-free compliance requirements against the #PBF suffix if applicable.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when picoampere bias currents and microvolt-level accuracy are critical alongside high-speed operation. It serves as a direct upgrade for systems previously using LF412A or OP-215 duals, though this is the quad variant. Consider the plastic N package for cost-sensitive designs where hermetic sealing is not required. Evaluate thermal management needs given the operating temperature limits.

Instrumentation, Op Amps, Buffer Amps Part Context

The LT1058 is part of the LT1057/LT1058 family of dual and quad JFET input precision high-speed op amps. While the LT1057 provides a matched dual configuration in an 8-pin package, the LT1058 offers four channels in a standard 14-pin configuration. Both devices replace popular bipolar and JFET input dual op amps, offering superior speed and precision combinations.
