Product details
Overview
LTC2057HMS8#PBF from Analog Devices (acquired Linear Technology) is a high-voltage, low-noise, zero-drift operational amplifier in an 8-lead MSOP package, delivering 4μV max input offset voltage, 0.015μV/°C max drift, and 200nVP-P DC–10Hz input noise. It operates from ±2.375V to ±18V (4.75V–36V single supply), features rail-to-rail output, V–-rail-inclusive input common-mode range, and shutdown mode - ideal for precision thermocouple amplification and high-resolution data acquisition.
For engineers reviewing the LTC2057HMS8#PBF datasheet, LTC2057HMS8#PBF pinout, LTC2057HMS8#PBF application, or LTC2057HMS8#PBF equivalent, key selection criteria include guaranteed –40°C to 125°C operation, 1.5MHz gain-bandwidth, 0.45V/μs slew rate, 160dB PSRR, and explicit MSOP-8 pin compatibility with SD/SDCOM shutdown control.
Technical Context
The LTC2057HMS8#PBF employs auto-zeroing and chopper stabilization to suppress 1/f noise and offset drift, achieving sub-microvolt DC precision over temperature and time. Its internal 100kHz chopping frequency is actively suppressed to minimize ripple artifacts at the output.
It integrates dual shutdown control (SD and SDCOM pins) enabling precise logic-level activation of ultra-low-current shutdown mode (≤9μA at 125°C), while maintaining full rail-to-rail output swing and input common-mode range extending to V– – 0.1V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | 4μV maximum - enables direct measurement of µV-level sensor signals without calibration drift. |
| Offset Drift | 0.015μV/°C maximum - ensures stable DC accuracy across automotive and industrial temperature ranges. |
| DC–10Hz Input Noise | 200nVP-P typical - critical for low-frequency precision applications like strain gauge and electronic scale front-ends. |
| Gain-Bandwidth Product | 1.5MHz typical - supports stable closed-loop gain ≥100 up to ~15kHz with unity-gain stability. |
| PSRR / CMRR | 160dB / 150dB typical - rejects power supply ripple and common-mode interference in noisy industrial environments. |
| Supply Range | 4.75V to 36V - accommodates wide-input industrial supplies and battery-backed systems without external regulation. |
| Shutdown Current | 9μA maximum at 125°C - enables low-power sleep modes in portable or energy-conscious instrumentation. |
Pinout & Package
8-lead plastic MSOP (MS8) package, 3mm × 3mm footprint, exposed pad not connected (no thermal tie required). Pin 1 = SD, Pin 2 = –IN, Pin 3 = +IN, Pin 4 = V–, Pin 5 = SDCOM, Pin 6 = V+, Pin 7 = OUT, Pin 8 = NC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (SD) | Shutdown Control Input | Active-high enable; requires ≥2V above SDCOM to exit shutdown - enables precise power sequencing. |
| Pin 2 (–IN) | Inverting Input | High-impedance node with 3pF differential capacitance - minimizes phase shift in high-Z sensor interfaces. |
| Pin 3 (+IN) | Non-Inverting Input | Same impedance and noise characteristics as –IN; supports true rail-to-rail common-mode input down to V– – 0.1V. |
| Pin 4 (V–) | Negative Supply Rail | Reference for all internal circuitry; also serves as exposed pad connection point in DFN variants (not applicable here). |
| Pin 5 (SDCOM) | Shutdown Reference | Defines logic threshold for SD; must be tied to V– or intermediate bias - prevents false shutdown during supply ramp. |
| Pin 6 (V+) | Positive Supply Rail | Supports up to 36V total supply; PSRR remains >130dB across full 4.75V–36V range. |
| Pin 7 (OUT) | Amplifier Output | Rail-to-rail capable; delivers 5mA load current with <100mV drop from rails at 125°C - suitable for driving ADC references directly. |
| Pin 8 (NC) | No Internal Connection | Unbonded die pad; must remain floating - no routing or grounding permitted. |
Key Features
| Feature | Design Value |
|---|---|
| Zero-drift architecture | Eliminates 1/f noise and long-term offset drift - maintains µV-level accuracy over years of operation. |
| V–-rail-inclusive input range | Accepts inputs down to V– – 0.1V - enables direct sensing of ground-referenced shunt voltages without level-shifting. |
| Chopping artifact suppression | Output ripple <1µVRMS at 100kHz - avoids aliasing into sensitive low-frequency measurement bands. |
| Shutdown with independent reference | SD/SDCOM dual-pin interface prevents spurious wake-up from supply transients or ground bounce. |
| High PSRR at full supply range | 133dB minimum PSRR from 4.75V to 36V - ensures stable performance across unregulated industrial rails. |

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 | Lower supply range (2.7–5.5V), 1μV max offset, no shutdown, SOIC-8 only | Not suitable for 36V industrial rails or shutdown-controlled systems | Select when operating strictly at 3.3V/5V and absolute lowest offset is prioritized over voltage range. |
| LTC2057HDD#PBF | Same specs, 3mm × 3mm DFN-8 package, exposed pad tied to V– | Superior thermal performance (θJA = 43°C/W vs 163°C/W), requires PCB thermal relief | Select for high-power-density designs needing lower junction temperature rise under continuous load. |
Compared with AD8628ARZ, LTC2057HMS8#PBF supports 7× wider supply range and integrated shutdown; compared with LTC2057HDD#PBF, it trades thermal efficiency for ease of hand-soldering and legacy board compatibility in MSOP footprints.

FAQ
What is the maximum supply voltage rating for LTC2057HMS8#PBF?
The LTC2057HMS8#PBF has an absolute maximum total supply voltage (V+ to V–) of 40V. Its specified operating range is 4.75V to 36V, making it suitable for industrial 24V systems and regulated 30V rails. Exceeding 40V risks permanent damage per Absolute Maximum Ratings.
Does LTC2057HMS8#PBF support rail-to-rail input operation?
LTC2057HMS8#PBF supports rail-to-rail *output* swing but its input common-mode range extends from V– – 0.1V to V+ – 1.5V - meaning it accepts inputs down to 0.1V below the negative rail, but not fully to V+, limiting true rail-to-rail input capability. This V–-inclusive range is essential for low-side current sensing.
How does the shutdown function work on LTC2057HMS8#PBF?
The LTC2057HMS8#PBF uses dual-pin shutdown: SD (Pin 1) and SDCOM (Pin 5). Shutdown activates when SD is ≤0.8V relative to SDCOM; exit occurs when SD ≥2.0V relative to SDCOM. SDCOM must be tied to a stable reference (e.g., V–) - this architecture prevents false triggering from supply noise.
What is the guaranteed input offset voltage specification for LTC2057HMS8#PBF over temperature?
LTC2057HMS8#PBF guarantees a maximum input offset voltage of 4μV across the full –40°C to +125°C operating range. This is a design-limited maximum, not a typical value, ensuring worst-case DC accuracy for safety-critical or metrology-grade designs without trimming.
Is LTC2057HMS8#PBF pin-compatible with other members of the LTC2057 family?
Yes - LTC2057HMS8#PBF shares identical pinout and functionality with all MS8-package variants (e.g., LTC2057IMS8#PBF, LTC2057HVHMS8#PBF). Differences lie only in voltage rating (LTC2057 vs LTC2057HV) and temperature grade (I vs H), not pin assignment or electrical behavior within rated conditions.
