Product details
Overview
LTC2057IS8#PBF from Analog Devices (formerly Linear Technology) is a high-voltage, low-noise, zero-drift operational amplifier in an 8-lead SOIC 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 supplies (4.75V–36V total), features rail-to-rail output, and is used in precision thermocouple amplifiers and electronic scales.
For engineers reviewing the LTC2057IS8#PBF datasheet, LTC2057IS8#PBF pinout, LTC2057IS8#PBF application, or LTC2057IS8#PBF equivalent, key selection criteria include its guaranteed 4μV max VOS over –40°C to 85°C, shutdown mode with 3μA typical quiescent current, and 1.5MHz gain-bandwidth product enabling stable unity-gain operation in high-resolution data acquisition front-ends.
Technical Context
The LTC2057IS8#PBF implements auto-zeroing and chopper stabilization in cascade to suppress both DC offset and 1/f noise, achieving near-zero drift over temperature and time. Its input stage includes ESD-protected CMOS inputs with V––0.1V to V+–1.5V common-mode range and rail-to-rail output swing.
Internal chopping occurs at 100kHz, with spurious ripple suppressed to <1μVRMS; the amplifier remains unity-gain stable and supports shutdown via SD/SDCOM differential control with 0.8V/2.0V thresholds. PSRR and CMRR exceed 133dB and 114dB respectively across full temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | 4.75V to 36V total (±2.375V to ±18V); enables direct interface with industrial ±15V rails and battery-powered 5V/12V systems |
| Input Offset Voltage | 4μV maximum (–40°C to 85°C); ensures ≤0.0004% error in 1V full-scale precision measurement |
| Offset Drift | 0.015μV/°C maximum; contributes <0.2μV error over 100°C ambient shift |
| DC–10Hz Noise | 200nVP-P typical; supports sub-16-bit resolution in slow-sampling sensor interfaces |
| Gain-Bandwidth | 1.5MHz typical; provides stable closed-loop gain ≥10 up to 150kHz |
| Slew Rate | 0.45V/μs typical (falling); limits full-scale step response to ≥2.2μs for 1V output swing |
| PSRR / CMRR | 133dB / 114dB minimum (–40°C to 85°C); rejects >2M:1 supply and common-mode interference |
| Shutdown Current | 3μA typical at 25°C; reduces system standby power by >99% vs active mode (0.88mA) |
Pinout & Package
8-lead plastic SOIC (S8) package, 3.9mm × 4.9mm body, 1.27mm pitch; exposed pad not present; RoHS-compliant matte tin finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: SD | Shutdown control input | Differential input referenced to SDCOM; asserts shutdown when SD–SDCOM < 0.8V |
| 2: –IN | Inverting input | High-impedance CMOS node; bias current ≤30pA (–40°C to 85°C) |
| 3: +IN | Non-inverting input | Matches –IN characteristics; supports precision differential sensing |
| 4: V– | Negative supply rail | Connects to system ground or negative rail; powers internal charge pumps |
| 5: NC | No internal connection | Not bonded; must be left floating or grounded per layout best practices |
| 6: OUT | Amplifier output | Rail-to-rail capable; drives ≥10mA load while maintaining 100mV headroom |
| 7: V+ | Positive supply rail | Accepts up to +36V; PSRR >133dB minimizes supply ripple coupling |
| 8: SDCOM | Shutdown reference | Reference point for SD threshold; must be tied to V– or stable bias within V– to (V+–2V) |
Key Features

| Wide input common-mode range | Extends to V– – 0.1V, enabling direct sensing of signals near ground in low-side current monitoring |
| Differential shutdown control | SD/SDCOM interface rejects common-mode noise on control lines, improving reliability in noisy industrial environments |

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 and pinout; rated for –40°C to 125°C operating range vs. –40°C to 85°C | Required for under-hood automotive or high-temp industrial deployments where ambient exceeds 85°C | Select when extended temperature qualification is mandatory; otherwise LTC2057IS8#PBF offers identical performance at lower cost |
| ADA4522-1ARZ | Zero-drift op-amp with 2.5μV max VOS, 0.005μV/°C drift, but narrower 4.5V–55V supply range and no shutdown function | Suitable for ultra-high-precision lab equipment where lowest drift dominates; unsuitable where shutdown or 36V compliance is needed | Choose ADA4522-1ARZ only if drift <0.005μV/°C is required and shutdown is unnecessary; LTC2057IS8#PBF provides broader feature set for industrial use |
Compared with LTC2057HMS8#PBF, the LTC2057IS8#PBF trades extended temperature rating for cost efficiency in commercial-grade applications, while ADA4522-1ARZ offers superior drift but lacks shutdown and has incompatible supply headroom above 36V-making LTC2057IS8#PBF the optimal balance of precision, robustness, and functionality for general-purpose high-dynamic-range measurement.

FAQ
What is the maximum input offset voltage specification for LTC2057IS8#PBF over its full operating temperature range?
The LTC2057IS8#PBF has a maximum input offset voltage of 4μV across the full –40°C to +85°C operating temperature range, as specified in the Electrical Characteristics table under "VOS Input Offset Voltage (Note 3)" with the "l" symbol denoting full-range guarantee.
Does LTC2057IS8#PBF support rail-to-rail output swing, and what is the minimum load condition for this specification?
Yes, LTC2057IS8#PBF provides rail-to-rail output swing. The specification guarantees output voltage within 100mV of either rail (V+ or V–) with no load, and within 270mV at 5mA sink/source current, as documented in the "Output Voltage Swing Low/High" rows of the Electrical Characteristics tables.
What is the shutdown current consumption of LTC2057IS8#PBF at 25°C, and how is shutdown activated?
The LTC2057IS8#PBF draws 3μA typical supply current in shutdown mode at 25°C. Shutdown is activated differentially: assert SD relative to SDCOM such that (SD – SDCOM) < 0.8V (low threshold); SDCOM must be biased within V– to (V+ – 2V).
Can LTC2057IS8#PBF operate from a single 5V supply, and what is its input common-mode range in that configuration?
Yes, LTC2057IS8#PBF operates from a single 5V supply (V+ = 5V, V– = 0V). Its input common-mode range is V– – 0.1V to V+ – 1.5V, i.e., –0.1V to +3.5V, allowing direct sensing of signals slightly below ground and up to 3.5V-ideal for low-side current sensing.
What is the gain-bandwidth product and slew rate of LTC2057IS8#PBF, and how do they affect small-signal bandwidth at unity gain?
The LTC2057IS8#PBF has a 1.5MHz typical gain-bandwidth product and 0.45V/μs typical falling slew rate. At unity gain, the small-signal –3dB bandwidth is approximately 1.5MHz, limited by GBW; the slew rate imposes a ~2.2μs full-scale settling time for a 1V step, making it suitable for DC–100kHz precision signal paths.
