Product details
Overview
LTC2057HVHMS8#PBF from Analog Devices (formerly Linear Technology) is a high-voltage, zero-drift operational amplifier designed for precision DC signal conditioning in demanding industrial and test instrumentation systems. It delivers 4.75V to 60V supply operation, 4μV max input offset voltage, 0.015μV/°C max drift, and rail-to-rail output swing - enabling accurate low-level signal amplification in electronic scales, thermocouple interfaces, and high-resolution data acquisition.
For engineers reviewing the LTC2057HVHMS8#PBF datasheet, LTC2057HVHMS8#PBF pinout, LTC2057HVHMS8#PBF application, or LTC2057HVHMS8#PBF equivalent, key selection criteria include its 60V max supply rating, shutdown mode capability, 1.5MHz gain-bandwidth product, and guaranteed performance over –40°C to +125°C.
Technical Context
The LTC2057HVHMS8#PBF employs auto-zeroing and chopper stabilization to suppress 1/f noise and offset drift, achieving sub-microvolt DC precision without external trimming. Its input common mode range extends to V– – 0.1V and V+ – 1.5V, supporting low-side current sensing and reference buffering with single-supply flexibility.
Internal shutdown control uses differential SD/SDCOM pins with 0.8V low and 2.0V high thresholds, enabling robust power management in battery- or energy-constrained systems. The amplifier remains unity-gain stable and features 160dB PSRR and 150dB CMRR (typ), critical for rejecting supply and common-mode interference in noisy environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 4.75V to 60V - supports wide-input industrial rails and high-voltage sensor interfaces without external regulators. |
| Input Offset Voltage | 4μV (max) - enables direct amplification of µV-level signals (e.g., thermocouples) without calibration overhead. |
| Offset Drift | 0.015μV/°C (max) - ensures <1µV total drift over full –40°C to +125°C range, critical for unattended long-term measurements. |
| DC–10Hz Noise | 200nVP-P - preserves signal integrity in low-frequency applications like strain gauge and load cell readouts. |
| Gain-Bandwidth | 1.5MHz (typ) - provides sufficient bandwidth for 10kHz closed-loop gain-of-100 instrumentation amplifier designs. |
| Slew Rate | 0.45V/μs (typ) - supports fast settling of step inputs while maintaining stability with capacitive loads up to 200pF. |
| PSRR / CMRR | 160dB / 150dB (typ) - rejects power supply ripple and common-mode interference in shared-rail industrial backplanes. |
Pinout & Package
8-lead plastic MSOP (MS8) package with exposed pad connected to V–; thermal resistance θJA = 163°C/W. 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 |
|---|---|---|
| SD (Pin 1) | Shutdown control input | Differential threshold pin requiring SD–SDCOM ≥2.0V to enable; allows system-level power sequencing. |
| –IN (Pin 2) | Inverting input | High-impedance node with 30pA max bias current at –40°C to 85°C; optimized for low-noise feedback networks. |
| +IN (Pin 3) | Non-inverting input | Matches –IN in bias current and capacitance (3pF differential); essential for balanced transducer interfaces. |
| V– (Pin 4) | Negative supply rail | Reference for internal circuitry and exposed thermal pad; must be connected to PCB ground plane for thermal performance. |
| SDCOM (Pin 5) | Shutdown reference | Provides common-mode reference for SD; accepts V– to V+–2V, enabling flexible biasing in split- or single-supply systems. |
| V+ (Pin 6) | Positive supply rail | Supports up to 60V; internal protection limits absolute max to 65V - accommodates transient surges in motor-control environments. |
| OUT (Pin 7) | Amplifier output | Rail-to-rail swing with ≤100mV saturation at 5mA load; drives 1kΩ loads directly without buffer stages. |
| NC (Pin 8) | No internal connection | Unused terminal; must remain unconnected to avoid parasitic coupling or mechanical stress on bond wires. |
Key Features
| Feature | Design Value |
|---|---|
| Zero-drift architecture | Auto-zeroing + chopping eliminates 1/f noise and time-dependent offset drift - guarantees <1µV total error over 1000 hours. |
| High-voltage operation | 60V max supply enables direct interface with 48V industrial buses, HV sensors, and isolated power domains without level-shifting. |
| Rail-to-rail output | Delivers full dynamic range across V– to V+ - maximizes ADC utilization in 16-bit+ data acquisition systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LTC2057HVHDD#PBF | Same electrical specs but 3mm × 3mm DFN-8 package; θJA = 43°C/W vs 163°C/W for MS8. | Better thermal performance in high-power-density layouts; requires rework for existing MSOP footprints. | Select for space-constrained PCBs where thermal dissipation >150mW is expected. |
| AD8628ARZ | Max supply 26V; 1μV typ offset but 0.03μV/°C drift; no shutdown; SOIC-8 only. | Lacks high-voltage support and power management - unsuitable for 48V+ systems or battery-powered shutdown modes. | Choose only for ≤24V, non-shutdown, cost-sensitive applications where 0.03μV/°C drift is acceptable. |
Compared with LTC2057HVHMS8#PBF, the LTC2057HVHDD#PBF offers superior thermal efficiency in compact layouts, while the AD8628ARZ trades voltage range and shutdown for lower unit cost in legacy 24V instrumentation - neither is pin-compatible, requiring layout revision.

FAQ
What is the maximum supply voltage rating for the LTC2057HVHMS8#PBF?
The LTC2057HVHMS8#PBF has an absolute maximum total supply voltage (V+ to V–) of 65V, with a recommended operating range of 4.75V to 60V. This high-voltage capability enables direct use in 48V industrial systems and high-side sensing applications without external voltage regulation - a key differentiator from standard 36V op-amps like the LTC2057.
Does the LTC2057HVHMS8#PBF support rail-to-rail input common mode range?
No, the LTC2057HVHMS8#PBF does not support rail-to-rail input common mode. Its specified input common mode range is V– – 0.1V to V+ – 1.5V. This allows true low-side current sensing (down to V–) but excludes direct connection to V+ - a design trade-off that preserves precision while enabling high-voltage operation. For full rail-to-rail input, consider the LTC2057IMS8#PBF variant with reduced supply range.
How does the shutdown function operate on the LTC2057HVHMS8#PBF?
The LTC2057HVHMS8#PBF uses a differential shutdown interface: SD (Pin 1) and SDCOM (Pin 5). The amplifier enters shutdown when SD – SDCOM ≥ 2.0V (typ), drawing only 3µA at –40°C to 125°C. SDCOM accepts voltages from V– to V+ – 2V, allowing flexible biasing - e.g., tying SDCOM to V– and pulling SD to V+ enables simple single-pin control. This architecture improves noise immunity versus single-pin shutdown op-amps.
What is the typical DC to 10Hz input noise voltage of the LTC2057HVHMS8#PBF?
The typical DC to 10Hz input-referred noise voltage of the LTC2057HVHMS8#PBF is 200nVP-P, measured under standard conditions (VS = ±30V, TA = 25°C). This ultra-low flicker noise - combined with 0.015μV/°C drift - makes it suitable for static or slowly varying signals such as load cells, pressure transducers, and thermistor bridges where long-term stability is critical.
Is the LTC2057HVHMS8#PBF unity-gain stable?
Yes, the LTC2057HVHMS8#PBF is unity-gain stable and requires no external compensation. It maintains phase margin >45° into 10kΩ loads with up to 200pF capacitive load, as verified in Figure G56–G58 of the datasheet. This stability simplifies design in gain-of-1 buffer configurations common in reference voltage distribution and sensor front-ends - eliminating the need for isolation resistors or complex compensation networks.
