Product details
Overview
LTC2058IS8E#TRPBF from Analog Devices is a dual, low-noise, 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, 200nVP-P (DC–10Hz) input noise, and rail-to-rail output swing across a 4.75V to 36V supply range - enabling use in thermocouple amplifiers, electronic scales, and low-side current sensing.
For engineers reviewing the LTC2058IS8E#TRPBF datasheet, LTC2058IS8E#TRPBF pinout, LTC2058IS8E#TRPBF application, or LTC2058IS8E#TRPBF equivalent, key selection criteria include guaranteed –40°C to 85°C operation, shutdown mode with SD/SDCOM pins (not present in S8E package), and compatibility with high-impedance sensor interfaces requiring sub-microvolt stability.
Technical Context
The LTC2058IS8E#TRPBF implements auto-zeroing and chopper stabilization to suppress 1/f noise and offset drift, achieving near-zero long-term drift and <1µVRMS ripple at its 100kHz internal chopping frequency. Its dual-channel architecture shares no common circuitry between amplifiers except the power rails, ensuring channel-to-channel isolation.
It features a 2.5MHz gain-bandwidth product and 1.6V/μs slew rate while maintaining unity-gain stability and >120dB CMRR over its full input common-mode range (V– – 0.1V to V+ – 1.5V). The S8E package variant lacks shutdown functionality - all SD/SDCOM-related specs apply only to MSE12 packages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | 4.75V to 36V - supports single-supply (5V, 12V, 24V) and split-supply (±2.5V to ±15V) operation without rail constraints. |
| Input Offset Voltage | 5μV (max) - enables direct measurement of µV-level sensor outputs (e.g., thermocouples, strain gauges) without trimming. |
| Offset Drift | 0.025μV/°C (max, –40°C to 125°C) - ensures <1μV total drift over 40°C ambient change, critical for unattended instrumentation. |
| DC–10Hz Noise | 200nVP-P (typ) - provides clean baseline for high-resolution data acquisition with 18-bit+ effective resolution. |
| Gain-Bandwidth | 2.5MHz (typ) - allows stable closed-loop gain ≥10 up to ~250kHz, suitable for fast-settling reference buffers and active filters. |
| PSRR / CMRR | 150dB (typ) - rejects supply ripple and common-mode interference even at low frequencies, essential in noisy industrial environments. |
| Output Swing | Rail-to-rail - delivers full dynamic range into 1kΩ loads, minimizing headroom loss in low-voltage systems. |
Pinout & Package
Package: 8-Lead Plastic SO (S8E), exposed pad connected to V–. Pin 9 (exposed pad) must be soldered to PCB ground plane for thermal and electrical performance.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUTA | Amplifier A output - drives feedback network and load; capable of sourcing/sinking ≥20mA short-circuit current. |
| 2 | –INA | Amplifier A inverting input - high-impedance node (1012Ω || 20pF); sensitive to layout-induced leakage and thermocouple EMFs. |
| 3 | +INA | Amplifier A noninverting input - same impedance as –INA; matched routing required to minimize offset error from thermoelectric effects. |
| 4 | V– | Negative supply rail - also connects to exposed pad; serves as reference for all internal biasing and output stage. |
| 5 | +INB | Amplifier B noninverting input - electrically isolated from +INA; enables independent dual-channel signal paths. |
| 6 | –INB | Amplifier B inverting input - identical specs to –INA; no shared input-stage components with Channel A. |
| 7 | OUTB | Amplifier B output - fully independent output stage; supports separate gain configurations from OUTA. |
| 8 | V+ | Positive supply rail - supplies both amplifiers; PSRR >140dB ensures immunity to supply noise up to 100kHz. |
Key Features
| Feature | Design Value |
|---|---|
| Zero-drift architecture | Auto-zero + chopper hybrid eliminates 1/f noise and guarantees <0.025μV/°C drift - removes need for periodic recalibration in metrology tools. |
| Rail-to-rail output | Swings within 15mV of rails at 1mA load - preserves full ADC input range when buffering 16-/18-bit converters. |
| High PSRR/CMRR | 150dB typical rejection of supply and common-mode noise - maintains accuracy in battery-powered or motor-driven systems with noisy grounds. |
| Wide supply range | Operates from 4.75V to 36V - supports legacy 5V/12V rails and modern 24V industrial buses without level-shifting. |
| Low input bias current | 30pA (max, –40°C to 85°C) - enables use with >100MΩ source impedances (e.g., pH electrodes, piezoresistive sensors) without significant voltage error. |
Applications

IC Role / Device Role / Timing Role: Unity-gain stable, low-output-impedance driver - isolates reference from load variations while maintaining ppm-level DC accuracy. Use Value: Rail-to-rail output and 1.6V/μs slew rate ensure fast settling (<1µs) after reference turn-on, preventing DAC code errors during power-up sequencing. |

IC Role / Device Role / Timing Role: High-gain, low-offset difference amplifier - configured as current-sense amplifier with V–-referenced inputs for bidirectional sensing. Use Value: Input common-mode range extending to V– – 0.1V enables accurate sensing at near-ground potentials, avoiding level-shifting complexity in low-side configurations. |
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 VOS and 0.025μV/°C drift, but lower 2MHz GBW and no shutdown; SOT-23-5 package. | Lacks dual-channel integration - requires two devices for dual-sensor systems, increasing board area and matching complexity. | Select when space-constrained single-channel buffering is needed and dual-channel correlation is not required. |
| OPA2189IDR | Dual-channel, 0.005μV/°C drift (lower), 5.7MHz GBW, but higher 4.2nV/√Hz noise at 1kHz and no specified DC–10Hz P-P noise. | Better drift spec but higher broadband noise - less optimal for slow, high-resolution DC measurements where 1/f noise dominates. | Select for applications prioritizing ultra-low drift over sub-200nVP-P low-frequency noise, e.g., long-term environmental monitoring. |
Compared with AD8628ARZ and OPA2189IDR, the LTC2058IS8E#TRPBF uniquely balances ultra-low DC drift, industry-leading DC–10Hz noise, dual-channel integration, and wide supply flexibility - making it optimal for cost-sensitive, space-constrained instrumentation requiring guaranteed dual-channel correlation and minimal calibration overhead.

FAQ
What is the operating temperature range for the LTC2058IS8E#TRPBF?
The LTC2058IS8E#TRPBF is specified for operation from –40°C to +85°C. This industrial-grade temperature range is guaranteed by design and testing per Analog Devices' qualification standards, ensuring stable offset, noise, and bandwidth performance across the full span without derating.
Does the LTC2058IS8E#TRPBF support shutdown mode?
No, the LTC2058IS8E#TRPBF does not support shutdown mode. Shutdown functionality (via SD and SDCOM pins) is exclusive to the 12-lead MSOP (MSE) package variants (e.g., LTC2058IMSE#TRPBF). The S8E package has no SD/SDCOM pins and operates continuously when powered.
How does the LTC2058IS8E#TRPBF achieve its low input offset voltage drift?
The LTC2058IS8E#TRPBF achieves 0.025μV/°C max drift using a combined auto-zero and chopper stabilization architecture that periodically corrects input-stage mismatches. This dual-stage correction actively cancels temperature-dependent offset gradients, eliminating the need for external drift compensation networks.
Can the LTC2058IS8E#TRPBF drive capacitive loads without instability?
Yes, the LTC2058IS8E#TRPBF is unity-gain stable and can safely drive ≥100pF capacitive loads without external compensation. For loads >200pF, adding a small series resistor (5–10Ω) between the output and capacitor reduces overshoot while maintaining settling time under 1µs for 10-bit accuracy.
What layout practices are critical for achieving the specified 5μV offset in the LTC2058IS8E#TRPBF?
To achieve the guaranteed 5μV offset, avoid thermocouple EMFs by using identical copper traces, minimizing dissimilar metal junctions (e.g., connectors, relays), and routing +IN/–IN pairs symmetrically. Also, connect the exposed pad directly to a low-impedance V– plane and bypass V+/V– with 100nF ceramic capacitors close to pins 8 and 4.
