Product details
Overview
LTC2057HVIDD#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 4μV max input offset voltage, 0.015μV/°C max drift, 200nVP-P (DC–10Hz) input noise, and rail-to-rail output swing across a 4.75V to 60V supply range - enabling accurate low-side current sensing and thermocouple amplification.
For engineers reviewing the LTC2057HVIDD#PBF datasheet, LTC2057HVIDD#PBF pinout, LTC2057HVIDD#PBF application, or LTC2057HVIDD#PBF equivalent, key selection criteria include its HV-rated DFN-8 package, shutdown control interface, ±30V common-mode input range, and guaranteed performance over –40°C to 125°C.
Technical Context
The LTC2057HVIDD#PBF implements auto-zeroing with internal chopping at 100kHz to suppress 1/f noise and offset drift, achieving sub-microvolt DC precision without external calibration. Its input stage operates down to V– – 0.1V and up to V+ – 1.5V, supporting wide common-mode voltage monitoring in high-side or low-side configurations.
It integrates a dedicated shutdown circuit with SD/SDCOM pins referenced to V–, enabling <5μA quiescent current in sleep mode while maintaining fast wake-up (<10µs). The amplifier remains unity-gain stable with 1.5MHz GBW and 0.45V/µs slew rate, suitable for closed-loop gain-of-100 instrumentation topologies.
Key Specifications

|---|---|
| Supply Range | 4.75V to 60V - supports direct connection to industrial 24V, 48V, and battery-backed rails without external regulators. |
| Input Offset Voltage | 4μV max - enables µV-level DC measurement accuracy in strain gauge and electronic scale front-ends. |
| Offset Drift | 0.015μV/°C max - ensures stable null point over full –40°C to 125°C operating range, critical for automotive monitors. |
| DC–10Hz Noise | 200nVP-P typ - minimizes baseline wander in slow-sampling applications like thermocouple amplifiers. |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LTC2057HVHDD#PBF | Same silicon, rated for –40°C to 125°C (H-grade) vs. –40°C to 85°C (I-grade); identical electrical specs. | Required for extended-temperature automotive or under-hood industrial use. | Select when ambient operating temperature exceeds 85°C. |
| AD8628ARZ | Lower supply range (2.7V–6V), 1μV max offset, 0.005μV/°C drift, but no shutdown and 36V absolute max rating. | Suitable only for low-voltage, ultra-low-drift applications without HV or power management needs. | Choose only if system supply is <6V and shutdown is unnecessary. |

FAQ
What is the maximum supply voltage rating for the LTC2057HVIDD#PBF?
The LTC2057HVIDD#PBF has an absolute maximum total supply voltage (V+ to V–) of 65V, with recommended operation up to 60V. This HV rating enables direct use with 48V industrial buses and high-voltage sensor interfaces without external attenuation or regulation - a key differentiator from standard 36V op-amps like the LTC2057.
Does the LTC2057HVIDD#PBF require external components for zero-drift operation?
No, the LTC2057HVIDD#PBF integrates all auto-zeroing and chopping circuitry on-die. It requires only standard decoupling capacitors (0.1µF ceramic near V+/V–) and does not need external clock sources, trimming resistors, or nulling networks - simplifying layout and eliminating drift-related calibration steps in production.
How does the shutdown function work on the LTC2057HVIDD#PBF?
The LTC2057HVIDD#PBF uses dual-pin shutdown control: SD (Pin 1) and SDCOM (Pin 5). When SD – SDCOM < 0.8V, the amplifier enters shutdown with supply current dropping to ≤9μA; when SD – SDCOM > 2.0V, it operates normally. SDCOM must be tied to V– or a stable bias within V– to V+ – 2V - enabling robust GPIO or comparator-driven power gating.
Can the LTC2057HVIDD#PBF drive capacitive loads without oscillation?
Yes, the LTC2057HVIDD#PBF is unity-gain stable and characterized to drive ≥200pF loads without external compensation. Typical overshoot remains <10% for CL = 200pF at ±15V supply, verified in Figures G56–G58 of the datasheet - making it suitable for driving ADC input capacitors and long PCB traces in data acquisition systems.
What is the input common-mode voltage range of the LTC2057HVIDD#PBF?
The LTC2057HVIDD#PBF supports an input common-mode range from V– – 0.1V to V+ – 1.5V across its full supply range. This extends below the negative rail, enabling true single-supply operation and direct interfacing with grounded sensors such as thermocouples and low-side shunt resistors - unlike many rail-to-rail input op-amps that exclude the rails.
