Product details
Overview
LTC2057HVHMS#PBF from Analog Devices (formerly Linear Technology) is a high-voltage, zero-drift operational amplifier designed 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, and operates from ±2.375V to ±30V (4.75V–60V total supply). Its rail-to-rail output and V–-rail-inclusive input common-mode range support low-side current sensing and reference buffering.
For engineers reviewing the LTC2057HVHMS#PBF datasheet, LTC2057HVHMS#PBF pinout, LTC2057HVHMS#PBF application, or LTC2057HVHMS#PBF equivalent, key selection criteria include guaranteed 125°C operation, shutdown mode with 3μA typical quiescent current, 1.5MHz gain-bandwidth, and MSOP-8 package compatibility with space-constrained PCB layouts.
Technical Context
The LTC2057HVHMS#PBF employs auto-zeroing architecture with internal 100kHz chopping frequency to suppress 1/f noise and offset drift. Its dual-stage correction loop achieves stable DC performance without idle tones above 1μVRMS at 100kHz.
It integrates dedicated shutdown control (SD/SDCOM pins) enabling fast turn-on/turn-off with <10μs transient response, and features matched input capacitance (3pF differential, 3pF common-mode) for balanced high-impedance sensor interfacing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | 4.75V to 60V total - supports ±30V rails for high-dynamic-range industrial sensors |
| Input Offset Voltage | 4μV max - enables sub-10ppm accuracy in 16-bit+ data acquisition front-ends |
| Offset Drift | 0.015μV/°C max - ensures <0.5μV total drift over –40°C to 125°C operating range |
| DC–10Hz Noise | 200nVP-P typ - critical for thermocouple and strain gauge amplification |
| Gain-Bandwidth | 1.5MHz typ - sufficient for closed-loop gains up to 100 with stable phase margin |
| PSRR / CMRR | 160dB / 150dB typ - rejects power supply ripple and common-mode interference in noisy environments |
| Shutdown Current | 3μA typ at 125°C - enables low-power sleep modes in battery-backed instrumentation |
Pinout & Package
Package: 8-lead plastic MSOP (3mm × 3mm), exposed pad connected to V–. Thermal resistance θJA = 163°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 3: +IN | Non-inverting input | Differential input node with 3pF capacitance; matched bias current to –IN |
| 4: V– | Negative supply rail | Power ground reference; exposed pad must be soldered to PCB ground plane |

IC Role / Device Role / Timing Role: Unity-gain stable buffer with ultra-low drift and noise to preserve reference accuracy. Use Value: 4μV offset and 0.015μV/°C drift prevent reference degradation; 160dB PSRR isolates reference from digital supply noise. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LTC2057HMS8#PBF | Same architecture but rated for 4.75V–36V supply; 0.015μV/°C drift identical; 125°C rating retained | Not suitable for >36V systems (e.g., 48V industrial buses); lower PSRR (133dB) at high supply voltages | Select when system supply stays ≤36V and cost sensitivity outweighs HV margin |
| AD8628ARZ | Single 5V–16V supply only; 1μV max offset; 0.005μV/°C drift; no shutdown; SOIC-8 package | Cannot replace in ±30V or 60V single-supply designs; lacks SDCOM/SD control for power management | Choose for low-voltage, ultra-low-drift applications where shutdown and HV capability are unnecessary |
Compared with LTC2057HMS8#PBF and AD8628ARZ, the LTC2057HVHMS#PBF uniquely combines 60V operation, guaranteed 125°C performance, integrated shutdown, and MSOP-8 footprint-making it the only option for high-reliability, high-voltage precision sensing where thermal and supply margin are non-negotiable.

FAQ
What is the maximum supply voltage rating for the LTC2057HVHMS#PBF?
The LTC2057HVHMS#PBF has an absolute maximum total supply voltage of 65V, with a recommended operating range of 4.75V to 60V. This distinguishes it from the standard LTC2057 (max 40V), enabling use in 48V industrial systems and high-voltage sensor front-ends where transient margins are critical. Always observe derating guidelines per the datasheet's Absolute Maximum Ratings table.
Does the LTC2057HVHMS#PBF require external components for zero-drift operation?
No, the LTC2057HVHMS#PBF performs full auto-zeroing internally using its 100kHz chopping clock and dual-stage correction loop. No external capacitors, resistors, or calibration circuitry are needed-unlike chopper-stabilized op-amps requiring external nulling pins. The device achieves 4μV max offset and 0.015μV/°C drift autonomously across its –40°C to 125°C range.
How does the shutdown function work on the LTC2057HVHMS#PBF?
The LTC2057HVHMS#PBF uses a differential shutdown interface: SD and SDCOM pins define the enable threshold. When SD – SDCOM ≥ 2V, the amplifier operates normally; when ≤ 0.8V, it enters shutdown with supply current dropping to ≤9μA at 125°C. SDCOM must be biased between V– and V+ – 2V. This architecture prevents false triggering from supply bounce or noise.
Can the LTC2057HVHMS#PBF drive heavy capacitive loads?
The LTC2057HVHMS#PBF is unity-gain stable but exhibits increasing overshoot with capacitive loads >100pF. At 200pF, small-signal overshoot reaches ~25% (Figure G56–G58). For loads >100pF, add a 10Ω–50Ω series resistor at the output to isolate capacitance. Do not use for direct MOSFET gate driving or long cable termination without isolation.
Is the MSOP-8 package of the LTC2057HVHMS#PBF lead-free and RoHS compliant?
Yes, the LTC2057HVHMS#PBF carries the #PBF suffix indicating 100% matte tin lead finish, fully compliant with JEDEC J-STD-609 and RoHS Directive 2011/65/EU. The exposed pad is electrically connected to V– and must be soldered to a PCB thermal pad for both electrical integrity and thermal performance (θJA = 163°C/W).
