Product details
Overview
LTC2057HVIMS8#PBF from Analog Devices (formerly Linear Technology) is a high-voltage, zero-drift operational amplifier optimized for precision DC signal conditioning in demanding industrial and test equipment. 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 to 60V total). It serves as the front-end amplifier in thermocouple interfaces and low-side current sensing.
For engineers reviewing the LTC2057HVIMS8#PBF datasheet, LTC2057HVIMS8#PBF pinout, LTC2057HVIMS8#PBF application, or LTC2057HVIMS8#PBF equivalent, key selection criteria include its 60V supply capability, sub-μV offset stability over temperature, shutdown mode with SDCOM reference, and MSOP-8 package compatibility with space-constrained PCB layouts.
Technical Context
The LTC2057HVIMS8#PBF uses auto-zeroing and chopper stabilization to suppress 1/f noise and offset drift, achieving near-zero long-term drift without external calibration. Its internal chopping frequency is fixed at 100kHz, and spurious ripple is suppressed to <1μVRMS at that frequency.
It features dual-stage shutdown control via SD and SDCOM pins, enabling precise logic-level activation referenced to V–. The input common-mode range extends from V– – 0.1V to V+ – 1.5V, supporting single-supply operation with ground-referenced inputs while maintaining full CMRR performance.

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 | Max supply 26V; 1μV typ offset but 0.03μV/°C drift; no shutdown; SOIC-8 only. | Limited to ≤24V systems; unsuitable for 48V battery monitoring or high-voltage transducer interfaces. | Select when ultra-low 1kHz noise (1.5nV/√Hz) is prioritized over supply range and shutdown control. |

FAQ
What is the maximum supply voltage rating for the LTC2057HVIMS8#PBF?
The LTC2057HVIMS8#PBF has an absolute maximum total supply voltage of 65V and is specified for continuous operation from 4.75V to 60V. This allows direct integration into 48V industrial and automotive systems without external regulators or voltage dividers, unlike standard 36V op-amps such as the LTC2057.
Does the LTC2057HVIMS8#PBF require external capacitors for stability in unity-gain configuration?
No, the LTC2057HVIMS8#PBF is unity-gain stable and does not require external compensation capacitors. Its internal architecture ensures phase margin >60° across all supply voltages and temperatures, even with 200pF capacitive loads, as verified in Figure G56–G58 of the datasheet.
How does the shutdown function work on the LTC2057HVIMS8#PBF?
The LTC2057HVIMS8#PBF uses two dedicated pins - SD (pin 1) and SDCOM (pin 5) - to implement a differential shutdown threshold. When SD – SDCOM exceeds 2V, the amplifier activates; below 0.8V, it enters shutdown with supply current reduced to ≤3μA. SDCOM may be tied to V– for ground-referenced control.
Can the LTC2057HVIMS8#PBF drive a 10kΩ load while maintaining rail-to-rail output swing?
Yes. At 25°C and ±15V supplies, the LTC2057HVIMS8#PBF delivers output swing within 15mV of each rail into 10kΩ (Figure G41–G43). At 85°C and ±30V, it maintains ≤130mV drop at 1mA sink/source, ensuring full dynamic range for 24-bit ADC interfacing without external buffers.
What is the typical input noise voltage spectral density of the LTC2057HVIMS8#PBF at 1kHz?
The LTC2057HVIMS8#PBF has a typical input noise voltage spectral density of 13nV/√Hz at 1kHz, as specified in the LTC2057HV Electrical Characteristics table (page 6). This value increases slightly versus the standard LTC2057 (11–12nV/√Hz) due to higher supply voltage operation but remains among the lowest for chopper-stabilized op-amps in its class.
