Product details
Overview
LTC2057HVIS8#PBF from Analog Devices (formerly Linear Technology) is a high-voltage, zero-drift operational amplifier optimized for precision DC signal conditioning in wide-supply industrial and test instrumentation systems. It delivers 4μV max input offset voltage, 0.015μV/°C max drift, 200nVP-P (DC–10Hz) input noise, rail-to-rail output swing, and operates from ±2.375V to ±30V supplies (4.75V–60V total). It is used in thermocouple amplifiers and low-side current sense circuits requiring long-term stability.
For engineers reviewing the LTC2057HVIS8#PBF datasheet, LTC2057HVIS8#PBF pinout, LTC2057HVIS8#PBF application, or LTC2057HVIS8#PBF equivalent, key selection criteria include its 1.5MHz gain-bandwidth product, 0.45V/μs slew rate, shutdown mode with SD/SDCOM control, and guaranteed performance over –40°C to 85°C in the 8-lead SO package.
Technical Context
The LTC2057HVIS8#PBF employs auto-zeroing and chopper stabilization to suppress 1/f noise and offset drift, achieving sub-microvolt DC accuracy over temperature and time. Its internal chopping frequency is 100kHz, with spurious ripple suppressed to <1μVRMS at that frequency.
It features dual-stage input architecture enabling rail-to-rail output swing and an extended input common-mode range from V– – 0.1V to V+ – 1.5V. The device includes dedicated shutdown control (SD/SDCOM pins) with defined thresholds (0.8V low, 2.0V high) and supports indefinite output short-circuit duration.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LTC2057HVHS8#PBF | Same electrical specs, but rated for –40°C to 125°C operating range; higher max offset drift (0.025μV/°C). | Required for under-hood automotive or high-temp industrial enclosures where ambient exceeds 85°C. | Select when extended temperature qualification is mandatory; otherwise LTC2057HVIS8#PBF offers tighter drift spec at lower cost. |
| ADA4522-1ARZ | Lower input noise (11nV/√Hz @ 1kHz vs 13nV/√Hz), same 4μV max offset, but narrower supply (4.5–55V) and no shutdown pin. | Preferred where lowest broadband noise dominates; unsuitable where active power gating or >55V operation is needed. | Choose ADA4522-1ARZ for highest SNR in sensor front-ends; retain LTC2057HVIS8#PBF when shutdown, 60V support, or superior DC specs are required. |
Compared with LTC2057HVHS8#PBF, the LTC2057HVIS8#PBF provides lower offset drift (0.015 vs 0.025μV/°C) for improved stability in 0–85°C environments, while ADA4522-1ARZ trades shutdown capability and 60V tolerance for marginally better AC noise performance-making LTC2057HVIS8#PBF optimal for general-purpose high-voltage precision DC applications.

FAQ
What is the maximum supply voltage rating for the LTC2057HVIS8#PBF?
The LTC2057HVIS8#PBF has an absolute maximum total supply voltage of 65V (V+ to V–), with recommended operating range up to 60V. This high-voltage capability enables direct use with industrial ±15V, ±24V, or single 48V rails without external regulation-critical for robustness in factory automation and power monitoring systems where LTC2057HVIS8#PBF is deployed.
Does the LTC2057HVIS8#PBF require external compensation for unity-gain stability?
No, the LTC2057HVIS8#PBF is internally compensated and unity-gain stable. It can be configured as a voltage follower or in any closed-loop configuration with gain ≥1 without external capacitors or resistors. This simplifies PCB layout and eliminates tuning effort-especially valuable in space-constrained instrumentation designs using LTC2057HVIS8#PBF as a reference buffer or sensor interface amplifier.
How does the shutdown function work on the LTC2057HVIS8#PBF?
The LTC2057HVIS8#PBF uses a differential shutdown interface: SD pin must be ≥2.0V above SDCOM to enable operation, and ≤0.8V above SDCOM to enter shutdown (quiescent current <9μA). SDCOM can be tied to V– or biased within V– to V+ – 2V. This architecture prevents false triggering from supply transients-ensuring reliable power gating in multi-channel LTC2057HVIS8#PBF-based data loggers.
What is the input common-mode voltage range of the LTC2057HVIS8#PBF?
The LTC2057HVIS8#PBF supports an input common-mode range from V– – 0.1V to V+ – 1.5V. This extends below the negative rail, enabling true low-side current sensing where the shunt sits between load and ground. For example, with V– = 0V, inputs can go to –0.1V-allowing accurate amplification of millivolt shunt signals without level-shifting circuitry in LTC2057HVIS8#PBF-based motor controllers.
Is the LTC2057HVIS8#PBF pin-compatible with other members of the LTC2057 family?
Yes, the LTC2057HVIS8#PBF shares identical pinout and footprint with all 8-lead SO variants in the LTC2057/LTC2057HV family (e.g., LTC2057IS8#PBF, LTC2057HVHS8#PBF). This allows drop-in replacement across temperature grades and voltage versions-simplifying inventory management and design reuse in systems where LTC2057HVIS8#PBF serves as the baseline industrial-grade variant.
