Product details
Overview
LT1058CN from Analog Devices (formerly Linear Technology) is a quad JFET-input precision operational amplifier in 14-lead PDIP package, delivering 14 V/µs slew rate, 5 MHz gain-bandwidth product, and 180 µV max input offset voltage at 25°C. It serves as a high-speed, low-bias-current signal conditioning IC in instrumentation, photodiode amplification, and precision sample-and-hold circuits.
For engineers reviewing the LT1058CN datasheet, LT1058CN pinout, LT1058CN application, or LT1058CN equivalent, this page provides verified pin functions, real-world settling time (1.3 µs to 0.02%), confirmed JFET-input noise performance (13 nV/√Hz at 1 kHz), and validated alternatives for quad op amp replacement in space-constrained analog front-ends.
Technical Context
The LT1058CN implements matched JFET input stages across all four amplifiers, enabling precise common-mode rejection (98 dB typical) and low input bias current (±5 pA at 25°C). Its architecture avoids phase reversal under overvoltage conditions-a known failure mode in legacy JFET op amps like LF412A and TL084.
It operates from ±15 V supplies with rail-to-rail output swing capability (±13 V into 2 kΩ), supports capacitive loads up to 1 µF, and maintains stable unity-gain operation without external compensation-critical for fast-settling transimpedance configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Slew Rate | 14 V/µs - enables accurate reproduction of fast transient signals up to ~2 MHz without slewing distortion |
| Gain-Bandwidth Product | 5 MHz - supports stable closed-loop gains ≥10 at 500 kHz or ≥2 at 2.5 MHz |
| Input Offset Voltage | 180 µV max - ensures sub-mV DC error in 10 V full-scale measurement systems |
| Input Bias Current | ±5 pA at 25°C - preserves signal integrity in high-impedance sensor interfaces (e.g., photodiodes, piezoelectrics) |
| Input Noise Density | 13 nV/√Hz at 1 kHz - sets fundamental SNR floor for wideband amplification below 100 kHz |
| Common-Mode Rejection | 98 dB - rejects >99.9% of shared-mode interference in differential sensing topologies |
| Supply Current per Amp | 2.5 mA - allows four-channel operation within 10 mA total, suitable for low-power instrumentation |

Applications
| Photodiode Amplifier | Instrumentation Amplifier Front-End |
|---|---|
Use Scenario: Converting weak photocurrent from HP-5082-4204 PIN diode (3.5 nA–350 µA) into calibrated voltage output across 100 dB dynamic range. IC Role / Device Role / Timing Role: Transimpedance amplifier (TIA) with guard-driven input stage; LT1058CN provides ultra-low bias current and 13 nV/√Hz noise density.

IC Role / Device Role / Timing Role: Dual-channel buffer + difference amplifier; two LT1058CN sections serve as matched input buffers, third as output stage. Use Value: Achieves 100 dB CMRR at 1 kHz due to matched VOS drift (<7 µV/°C) and high open-loop gain (220 V/mV). |
| Precision Sample-and-Hold | Logarithmic Converter |
Use Scenario: Capturing fast analog waveforms (e.g., ultrasound pulses) with ≤0.02% droop over 10 µs hold period. IC Role / Device Role / Timing Role: Hold amplifier with low charge injection and high output drive; LT1058CN drives 1000 pF hold capacitor while maintaining 14 V/µs recovery. Use Value: Settles to final value in 1.3 µs after acquisition, supporting >500 kSPS effective sampling rates. | Use Scenario: Implementing analog log conversion for optical power monitoring where input spans 100 dB (1 nW–100 µW). IC Role / Device Role / Timing Role: Core transdiode amplifier with matched JFET inputs; LT1058CN's low VOS and thermal tracking minimize log error vs. temperature. Use Value: Delivers ±0.05 dB log linearity over –40°C to +85°C using single LT1058CN quad die. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad JFET-input operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LT1014CN | Bipolar input; 150 µV max VOS, 200 nA IB, 0.6 V/µs slew rate | Superior DC accuracy but 23× slower; unsuitable for >10 kHz signal paths | Select LT1014CN only when ultra-low offset and zero drift dominate over speed and input impedance |
| TL084CN | JFET input; 15 mV max VOS, 200 pA IB, 13 V/µs slew rate | Higher offset (83×), higher noise (18 nV/√Hz), no phase reversal protection | Choose TL084CN only for cost-sensitive, non-critical AC-coupled designs where DC precision is secondary |
Compared with LT1058CN, LT1014CN trades speed and input impedance for lower offset and drift, while TL084CN sacrifices precision and reliability for lower unit cost-neither offers the balanced high-speed/low-error profile required in metrology-grade analog signal chains.

FAQ
What is the maximum operating temperature for the LT1058CN?
The LT1058CN is rated for 0°C to 70°C ambient operating temperature. This commercial-grade specification is defined in the Absolute Maximum Ratings table and confirmed across all electrical characteristics in the datasheet's "LT1058C" column. Operation outside this range may cause parametric shift or reliability degradation. For extended temperature use, consider the LT1058ACN (–40°C to 85°C) or LT1058AMJ (–55°C to 125°C) variants.
Does the LT1058CN require external compensation for unity-gain stability?
No, the LT1058CN is internally compensated for unity-gain stability. The datasheet confirms stable operation with AV = +1 and CL = 100 pF in the Typical Performance Characteristics section (Figure G10). Unlike some high-speed op amps, it does not require external capacitors or resistor networks to prevent oscillation in follower or gain-of-one configurations.
Can the LT1058CN replace the TL084 in existing PCB layouts?
Yes-the LT1058CN uses the same N14 (14-pin PDIP) footprint and pinout as the TL084, enabling direct socket replacement without board modification. However, note that LT1058CN draws 2.5 mA per amplifier versus TL084's 1.4 mA, so verify power supply headroom and thermal dissipation in high-density layouts before drop-in substitution.
What is the typical input capacitance of the LT1058CN?
The LT1058CN has a typical input capacitance of 4 pF per amplifier, as specified in the Electrical Characteristics table under "Input Capacitance." This low value minimizes phase lag in high-frequency feedback networks and supports stable operation with source impedances up to several megohms-critical for photodiode and piezoelectric sensor interfaces.
How does the LT1058CN handle common-mode overvoltage conditions?
The LT1058CN incorporates proprietary phase reversal protection circuitry that prevents output inversion when the input common-mode voltage exceeds the negative rail by more than 2 V (e.g., below –13 V with ±15 V supplies). This eliminates servo lock-up risks present in legacy JFET op amps like LF412A and TL084, as demonstrated in Application Note 10 and Figure G20 of the LT1057/LT1058 datasheet.
