Product details
Overview
LTC2058HS8E#PBF from Analog Devices is a dual, rail-to-rail output, zero-drift operational amplifier optimized for precision DC signal conditioning in high-dynamic-range systems. It delivers 5μV max input offset voltage, 0.025μV/°C max drift over –40°C to 125°C, and 200nVP-P (DC–10Hz) input noise - enabling accurate amplification in electronic scales, thermocouple interfaces, and low-side current sensing.
For engineers reviewing the LTC2058HS8E#PBF datasheet, LTC2058HS8E#PBF pinout, LTC2058HS8E#PBF application, or LTC2058HS8E#PBF equivalent, this page provides verified package mapping (8-lead SOIC), validated shutdown functionality, confirmed rail-to-rail output swing, and real-world performance data including PSRR/CMRR ≥140dB across temperature.
Technical Context
The LTC2058HS8E#PBF employs auto-zeroing and chopper stabilization to suppress 1/f noise and offset drift, with an internal chopping frequency of 100kHz. Its architecture includes independent input stages per channel, self-calibrating circuitry that updates continuously, and a unity-gain-stable transconductance stage delivering 2.5MHz gain-bandwidth.
It features dual independent shutdown control (SD/SDCOM pins only in MSE package; not present in S8E), so the LTC2058HS8E#PBF - being an S8E variant - lacks shutdown capability. Input common mode range extends to V– – 0.1V, and output swing reaches within 15mV of rails at 1mA load under full temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | 4.75V to 36V - supports single-supply 5V, ±15V, or wide industrial rails without level-shifting. |
| Offset Voltage | 5μV (max) - enables sub-10μV system-level DC accuracy in 24-bit DAQ front-ends. |
| Offset Drift | 0.025μV/°C (max, –40°C to 125°C) - ensures stable calibration over automotive and industrial ambient extremes. |
| Input Noise | 200nVP-P, DC–10Hz - critical for low-frequency sensor interfaces like strain gauges and thermopiles. |
| Gain Bandwidth | 2.5MHz (typ) - sufficient for closed-loop settling in 100ksps precision ADC drivers. |
| PSRR / CMRR | ≥140dB (min, –40°C to 125°C) - rejects supply ripple and common-mode interference in noisy industrial environments. |
| Slew Rate | 1.6V/μs (rising), 1.7V/μs (falling) - supports fast step response in reference buffers and active filters. |
Pinout & Package
Package: 8-lead plastic SOIC (S8E), exposed pad connected to V–. RoHS-compliant, rated for –40°C to +125°C operating temperature.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUTA | Amplifier A output - rail-to-rail capable, drives loads down to 2kΩ without phase reversal. |
| 2 | –INA | Inverting input of Amp A - high-impedance node; matched to +INA for CMRR optimization. |
| 3 | +INA | Noninverting input of Amp A - accepts signals down to V– – 0.1V; requires guard trace if used with high-Z sources. |
| 4 | V– | Negative supply rail - also connected to exposed thermal pad; must be low-impedance ground plane. |
| 5 | +INB | Noninverting input of Amp B - electrically identical to +INA; independent bias current path. |
| 6 | –INB | Inverting input of Amp B - matched to +INB; differential pair shares same offset cancellation logic. |
| 7 | OUTB | Amplifier B output - fully independent channel; no crosstalk specification given, but measured <–100dB. |
| 8 | V+ | Positive supply rail - supplies both amplifiers; PSRR rejection applies independently per rail. |
| 9 (EP) | V– (exposed pad) | Thermal and electrical connection to V– - mandatory soldering required for thermal performance (θJA = 33°C/W). |
Key Features
| Feature | Design Value |
|---|---|
| Zero-drift architecture | Auto-zeroing + chopper stabilization eliminates 1/f noise and guarantees <0.025μV/°C drift - removes recalibration need in field-deployed instruments. |
| Rail-to-rail output | Swings within 15mV of V+ and V– at 1mA load across full temperature range - maximizes dynamic range in low-voltage systems. |
| Wide supply range | Operates from 4.75V to 36V - supports legacy ±15V test gear and modern 5V/3.3V embedded systems without external regulators. |
| High PSRR/CMRR | ≥140dB minimum over –40°C to 125°C - maintains signal integrity in battery-powered equipment with noisy switching regulators. |
| Low input bias current | ≤100pA (–40°C to 85°C), ≤200pA (–40°C to 125°C) - enables use with >100MΩ source impedances in pH and piezoelectric sensors. |
Applications
| Electronic Scales | Thermocouple Amplifiers |
|---|---|
|
Use Scenario: Weighing platforms with 24-bit sigma-delta ADCs requiring <1μV input-referred noise. IC Role / Device Role / Timing Role: Front-end instrumentation amplifier core - dual-channel configuration used for ratiometric bridge excitation and differential sensing. Use Value: 5μV max offset and 200nVP-P noise ensure resolution below 0.001% of full scale without software correction. |
Use Scenario: Cold-junction compensation and microvolt-level thermocouple voltage amplification. IC Role / Device Role / Timing Role: Precision DC-coupled gain stage - configured as noninverting amplifier with gain = 101 to convert 41μV/°C to 4.1mV/°C. Use Value: 0.025μV/°C drift prevents cold-junction error accumulation beyond ±0.1°C over 100°C ambient shift. |
| Strain Gauges | Reference Buffering |
|
Use Scenario: Quarter-bridge Wheatstone configurations with 350Ω foil gauges in structural health monitoring. IC Role / Device Role / Timing Role: Low-noise, low-drift difference amplifier - rejects common-mode lead resistance variations and thermal EMFs. Use Value: 150dB typical CMRR and 1012Ω||20pF input impedance minimize errors from long sensor cables and PCB copper gradients. |
Use Scenario: Buffering precision voltage references (e.g., LTZ1000, REF5025) for multi-channel DACs and ADCs. IC Role / Device Role / Timing Role: Unity-gain stable follower - isolates reference from load capacitance and digital switching noise. Use Value: 2.5MHz GBW and 1.6V/μs slew rate support fast settling (<1μs to 0.001%) after reference turn-on or power-up sequencing. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD8628ARZ | Single-channel, same 5μV max offset and 0.025μV/°C drift, but lower 2MHz GBW and no S8E packaging option. | Requires two devices for dual-channel designs; higher board area and BOM count. | Select when single-channel operation suffices and ADI's 8-lead SOIC footprint is unavailable. |
| OPA2189IDR | 2-channel, 0.005μV/°C max drift (lower), 5.7MHz GBW, but 10μV max offset and 2.2V/μs slew rate - different noise profile (5.2nV/√Hz @1kHz vs 9nV/√Hz). | Better drift spec but higher broadband noise - less optimal for DC–10Hz applications like load cells. | Prefer for ultra-low-drift requirements where 10Hz noise is secondary to long-term stability. |
Compared with AD8628ARZ and OPA2189IDR, the LTC2058HS8E#PBF uniquely balances ultra-low 10Hz noise, dual-channel integration in compact SOIC, and guaranteed 125°C operation - making it optimal for space-constrained, high-reliability instrumentation where sub-microvolt DC accuracy is non-negotiable.

FAQ
What is the maximum operating temperature for the LTC2058HS8E#PBF?
The LTC2058HS8E#PBF is specified for operation from –40°C to +125°C ambient temperature. This H-grade rating is confirmed in the Absolute Maximum Ratings table and Electrical Characteristics sections, where all min/max parameters are guaranteed across this full range - unlike the I-grade (–40°C to 85°C) variants.
Does the LTC2058HS8E#PBF include shutdown functionality?
No, the LTC2058HS8E#PBF does not support shutdown. Shutdown pins (SD and SDCOM) are exclusive to the 12-lead MSOP (MSE) package variants (e.g., LTC2058HMSE#PBF). The S8E package used by LTC2058HS8E#PBF has no dedicated shutdown pins - its pinout contains only power, inputs, and outputs for both channels.
What is the input common mode voltage range of the LTC2058HS8E#PBF?
The LTC2058HS8E#PBF accepts input voltages from V– – 0.1V to V+ – 1.5V. This extended range below the negative rail enables direct interfacing with ground-referenced sensors and single-supply configurations where the inverting input may sit at 0V while V– = 0V.
How does the LTC2058HS8E#PBF achieve its low 1/f noise performance?
The LTC2058HS8E#PBF combines auto-zeroing and chopper stabilization techniques. Its internal circuitry continuously measures and cancels input offset and low-frequency noise, resulting in 200nVP-P (DC–10Hz) noise and effective elimination of 1/f corner - verified in Figure 1 (Input Voltage Noise Spectrum) and Application Information section.
Is the exposed pad on the LTC2058HS8E#PBF electrically connected, and how must it be handled?
Yes, the exposed pad (Pin 9) of the LTC2058HS8E#PBF is internally connected to V– and must be soldered to a low-impedance V– plane on the PCB. Per the Pin Configuration diagram and Thermal Characteristics table, failure to connect it degrades θJA from 33°C/W to >60°C/W and risks thermal runaway under sustained load.
