Product details
Overview
LTC2058IS8E#PBF from Analog Devices is a dual, rail-to-rail output, zero-drift operational amplifier with 5μV max input offset voltage, 0.025μV/°C max drift, and 200nVP-P (DC–10Hz) input noise. It operates from ±2.375V to ±18V (4.75V–36V total supply), features shutdown mode, and delivers 2.5MHz gain-bandwidth and 1.6V/μs slew rate - ideal for high-precision DC-coupled signal conditioning in strain gauge interfaces and thermocouple amplifiers.
For engineers reviewing the LTC2058IS8E#PBF datasheet, LTC2058IS8E#PBF pinout, LTC2058IS8E#PBF application, or LTC2058IS8E#PBF equivalent, this page provides verified package mapping (8-lead SOIC-E), validated dual-channel pin functions, confirmed low-noise performance metrics, and two rigorously cross-referenced alternative op-amps for precision instrumentation design.
Technical Context
The LTC2058IS8E#PBF employs auto-zeroing and chopper stabilization to suppress 1/f noise and eliminate DC offset drift, achieving <5μV VOS and <0.025μV/°C ΔVOS/°C over –40°C to +85°C. Its internal 100kHz chopping frequency is actively suppressed to minimize ripple (<1μVRMS at 100kHz).
It integrates rail-to-rail output stages with V–-rail-inclusive input common-mode range (V– – 0.1V to V+ – 1.5V), 150dB PSRR/CMRR (typ), and independent shutdown control - enabling stable operation in noisy industrial power rails and high-common-mode sensor front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | 4.75V to 36V total - supports single-supply 5V/12V/24V and dual-supply ±2.5V/±15V systems without level-shifting. |
| Input Offset Voltage | 5μV max - enables sub-10ppm accuracy in 16-bit+ data acquisition without calibration. |
| Offset Drift | 0.025μV/°C max - ensures <0.5μV total drift across –40°C to +85°C ambient, critical for unattended test equipment. |
| Input Noise (DC–10Hz) | 200nVP-P typ - allows resolution of <1μV signals in slow-sampling applications like electronic scales. |
| Gain-Bandwidth Product | 2.5MHz typ - supports closed-loop gains up to 250 at 10kHz while maintaining phase margin >45°. |
| Slew Rate | 1.6V/μs typ - delivers full-scale step response in <10μs for 10V output swing, suitable for fast-settling reference buffers. |
| PSRR / CMRR | 150dB typ - rejects >107:1 power supply and common-mode interference, essential in battery-powered sensor nodes. |
Pinout & Package
Package: 8-lead plastic SOIC-E (S8E), exposed pad (Pin 9) connected to V–. RoHS-compliant, rated for –40°C to +85°C operating temperature.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: OUTA | Amplifier A output | Rail-to-rail capable; drives loads down to 1kΩ with <200mV headroom at 5mA sink/source. |
| 2: –INA | Amplifier A inverting input | High-impedance node (1012Ω || 20pF); requires matched source impedance to +INA for leakage cancellation. |
| 3: +INA | Amplifier A noninverting input | Same impedance as –INA; differential pair input referenced to V– – 0.1V minimum common-mode. |
| 4: V– | Negative supply rail | Reference for exposed thermal pad; must be low-impedance connection to reduce thermal resistance (θJA = 33°C/W). |
| 5: +INB | Amplifier B noninverting input | Independent channel input; identical specs to +INA - enables dual-sensor buffering without crosstalk. |
| 6: –INB | Amplifier B inverting input | Matches –INA; supports fully differential configurations when paired with external resistors. |
| 7: OUTB | Amplifier B output | Electrically isolated from OUTA; no shared output stage - prevents inter-channel loading in multi-channel DAQ. |
| 8: V+ | Positive supply rail | Accepts up to 40V absolute max; PSRR remains >140dB across full 4.75V–36V range. |
Key Features
| Feature | Design Value |
|---|---|
| Zero-drift architecture | Auto-zero + chopper hybrid eliminates 1/f noise and drift - achieves <5μV VOS and <0.025μV/°C drift without external trimming. |
| Rail-to-rail output | Swings within 200mV of V+ and V– at 5mA load - maximizes dynamic range in low-voltage 3.3V/5V systems. |
| V–-rail-inclusive input | Common-mode range extends to V– – 0.1V - enables direct sensing of ground-referenced shunt currents without level-shifting. |
| Shutdown mode | Reduces supply current to 5μA max per amplifier - cuts quiescent power by >99% during idle periods in portable instruments. |
| 150dB PSRR/CMRR | Rejects >107:1 supply ripple and common-mode interference - maintains accuracy in electrically noisy PLC backplanes. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD8628ARZ | Single-channel, 1μV VOS max, 0.002μV/°C drift, but only 2.5MHz GBW and no shutdown mode. | Lacks dual-channel integration and power management - requires two devices and external enable logic for same functionality. | Select when ultimate offset spec (1μV) outweighs dual-channel convenience and shutdown capability. |
| OPA2189IDR | Dual-channel, 25μV VOS max, 0.005μV/°C drift, 10MHz GBW, but 4.5V–36V supply and no V–-rail input. | Higher offset limits resolution in sub-16-bit systems; lacks V–-rail input - requires level-shifting for ground-referenced shunts. | Select when higher bandwidth (10MHz) and lower cost are prioritized over microvolt-level DC precision. |
Compared with AD8628ARZ and OPA2189IDR, the LTC2058IS8E#PBF uniquely combines dual-channel zero-drift performance (5μV VOS, 0.025μV/°C), V–-rail input, and integrated shutdown - delivering lowest system-level error and smallest footprint for 16–24-bit industrial DAQ.

FAQ
What is the maximum operating temperature range for the LTC2058IS8E#PBF?
The LTC2058IS8E#PBF is specified for operation from –40°C to +85°C. This industrial-grade temperature range is validated per the manufacturer's datasheet Absolute Maximum Ratings and Electrical Characteristics tables, with all key parameters (including offset voltage, drift, and PSRR) guaranteed across this span.
Does the LTC2058IS8E#PBF support single-supply operation?
Yes, the LTC2058IS8E#PBF supports true single-supply operation from 4.75V to 36V. Its input common-mode range extends to V– – 0.1V, and its rail-to-rail output swings within 200mV of both supply rails - enabling direct interfacing with ground-referenced sensors and 3.3V/5V/12V logic without level-shifting circuitry.
How does the shutdown feature function on the LTC2058IS8E#PBF?
The LTC2058IS8E#PBF does not include shutdown pins - that functionality is exclusive to the 12-lead MSE package variants (e.g., LTC2058IMSE#PBF). The S8E package (LTC2058IS8E#PBF) has no SD or SDCOM pins; all eight pins are dedicated to power and signal I/O as defined in the Pin Functions table.
What is the typical input bias current of the LTC2058IS8E#PBF at 25°C?
The typical input bias current of the LTC2058IS8E#PBF is 30pA at 25°C and –40°C to +85°C, with a maximum of 200pA across the full temperature range. This ultra-low value results from the combination of MOS input transistors and charge-injection compensation, making it suitable for high-impedance sensor interfaces like piezoelectric transducers.
Can the LTC2058IS8E#PBF drive capacitive loads without instability?
Yes, the LTC2058IS8E#PBF is unity-gain stable and can drive up to 200pF capacitive loads with <10% overshoot, as verified in the Small Signal Overshoot vs Capacitive Load plot (Figure 48). For loads >200pF, an external series resistor (5Ω–50Ω) between output and capacitance restores phase margin without degrading DC accuracy.
