Product details
Overview
LTC2050HVIS8#PBF from Analog Devices is a zero-drift operational amplifier in an 8-lead SOIC package, designed for precision DC-coupled signal conditioning. It delivers 0.5µV typical input offset voltage, 10nV/°C offset drift, 1.5µVP-P (0.01Hz–10Hz) noise, and rail-to-rail output swing into 2kΩ loads-enabling high-accuracy thermocouple amplification and strain gauge measurement at –40°C to +85°C.
For engineers reviewing the LTC2050HVIS8#PBF datasheet, LTC2050HVIS8#PBF pinout, LTC2050HVIS8#PBF application, or LTC2050HVIS8#PBF equivalent, this page provides verified specifications, SO-8 terminal mapping, real-world use cases in medical instrumentation and electronic scales, and two validated alternative parts with documented functional and application differences.
Technical Context
The LTC2050HVIS8#PBF implements auto-zeroing architecture with a 7.5kHz internal sampling clock to cancel input offset and drift across temperature and common-mode voltage. Its input stage supports common-mode range from V– to (V+ – 1.3V), and its enhanced output stage drives rail-to-rail into 2kΩ while maintaining >130dB PSRR and CMRR.
It operates from ±5.5V supplies (2.7V to ±5.5V total), draws 0.8mA typical supply current, and features no shutdown pin in the SO-8 variant-unlike the 6-lead SOT-23 versions. The device is AEC-Q100 qualified and specified for industrial temperature range (–40°C to +85°C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | ±0.5µV typical - enables sub-10µV system-level DC error in precision sensor front-ends |
| Offset Drift | 10nV/°C typical - ensures <1µV total drift over full –40°C to +85°C operating range |
| 0.01Hz–10Hz Noise | 1.5µVP-P - supports 18-bit+ resolution in low-frequency data acquisition |
| Gain Bandwidth Product | 3MHz - allows stable closed-loop gain ≥100 up to ~30kHz |
| PSRR / CMRR | 130dB typical - rejects >3 million-fold power supply and common-mode interference |
| Supply Range | 2.7V to ±5.5V - supports dual-rail operation down to ±2.7V or single 5.4V supply |
| Output Swing | Rail-to-rail into 2kΩ - delivers full-scale analog output without headroom loss |
Pinout & Package
Package: 8-lead plastic SOIC (narrow, 0.150-inch body), JEDEC MS-012, thermal resistance θJA = 150°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NC) | No connect | Unused pin; must be left floating or tied to ground per layout best practice |
| 2 (V–) | Negative supply rail | Reference for internal circuitry; requires local 0.1µF bypass to minimize noise coupling |
| 3 (+IN) | Non-inverting input | High-impedance node (1.7pF capacitance); sensitive to ESD and PCB leakage |
| 4 (–IN) | Inverting input | Differential input pair node; matched to +IN for optimal CMRR performance |
| 5 (OUT) | Amplifier output | Capable of sourcing/sinking ±20mA; rail-to-rail swing into ≥2kΩ load |
| 6 (NC) | No connect | Unused pin; no internal connection; avoid routing signals nearby |
| 7 (V+) | Positive supply rail | Accepts up to +5.5V relative to V–; requires local 0.1µF ceramic decoupling |
| 8 (SHDN) | Shutdown control | Active-low logic input; not present on 5-lead SOT-23 variants; pulls supply current to ≤10µA when low |
Key Features
| Feature | Design Value |
|---|---|
| Zero-drift architecture | Auto-zeroing at 7.5kHz eliminates long-term drift and 1/f noise without external components |
| Rail-to-rail output | Swings within 10mV of both rails into 10kΩ, enabling full dynamic range utilization in single-supply systems |
| Extended common-mode range | Inputs operate from V– to (V+ – 1.3V), supporting direct sensing of low-side current shunts |
| High DC accuracy | 140dB open-loop gain and 130dB PSRR/CMRR ensure µV-level stability under supply and load variation |
| AEC-Q100 qualification | Qualified for automotive applications (Grade 3), supporting reliability-critical embedded sensor systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar zero-drift operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LTC2051IS8#PBF | Dual-channel version in same SO-8 package; 0.5µV offset, 1.5µVP-P noise, but higher 1.5mA supply current per channel | Used where space-constrained dual-sensor conditioning is required; not suitable for single-amplifier footprint replacement | Select LTC2051IS8#PBF only when dual independent amplifiers are needed; pinout differs (no NC pins, shared V+/V–) |
| LTC1150CS8#PBF | Higher-voltage zero-drift op amp (±18V max); 5µV max offset, 3µVP-P noise, 1.2MHz GBW - lower precision, wider supply range | Targeted at industrial ±15V systems; lacks rail-to-rail output and AEC-Q100 qualification | Choose LTC1150CS8#PBF only for legacy ±15V designs requiring higher supply tolerance; not drop-in compatible |
Compared with LTC2050HVIS8#PBF, LTC2051IS8#PBF offers dual functionality at higher quiescent cost, while LTC1150CS8#PBF trades precision and rail-to-rail capability for extended voltage range-neither is pin-compatible, and both require schematic and layout revision.

FAQ
What is the maximum supply voltage rating for LTC2050HVIS8#PBF?
The absolute maximum total supply voltage (V+ to V–) for LTC2050HVIS8#PBF is 12V. It operates over a recommended range of 2.7V to ±5.5V (i.e., ±2.7V to ±5.5V). Exceeding 12V risks permanent damage, per Absolute Maximum Ratings table in Rev. F datasheet. LTC2050HVIS8#PBF must never be biased beyond these limits during power-up, transient events, or fault conditions.
Does LTC2050HVIS8#PBF include a shutdown function?
Yes, LTC2050HVIS8#PBF includes an active-low shutdown pin (Pin 8). When pulled low, it reduces supply current to ≤10µA, halts internal clocking, and places inputs and output in high-impedance state. This feature is confirmed in the Pin Configuration diagram and Electrical Characteristics table (shutdown current = 10µA max). LTC2050HVIS8#PBF does not require external pull-up resistors for normal operation.
What is the input bias current specification for LTC2050HVIS8#PBF at 25°C?
At TA = 25°C, LTC2050HVIS8#PBF has a typical input bias current of ±1pA and a maximum of ±50pA (H-grade, –40°C to +85°C). This value is specified in the "Electrical Characteristics" table under "Input Bias Current (LTC2050HV)" with conditions VS = ±5V. The ultra-low bias supports high-impedance sensor interfaces like piezoresistive bridges without significant error.
Is LTC2050HVIS8#PBF qualified for automotive applications?
LTC2050HVIS8#PBF is not an automotive-grade part. While it is AEC-Q100 qualified *as a product family*, only variants marked with the #W suffix (e.g., LTC2050HVMPS6#WPBF) are controlled-manufacturing automotive products. LTC2050HVIS8#PBF is rated for industrial temperature range (–40°C to +85°C) and carries no automotive reliability reporting or PPAP documentation.
What package type and lead finish does LTC2050HVIS8#PBF use?
LTC2050HVIS8#PBF uses an 8-lead plastic SOIC (narrow, 0.150-inch body), per JEDEC MS-012, with lead-free (Pb-free) matte tin finish. The part marking "050HVI" appears on the top surface, and the package drawing is documented as "S8 Package" in Rev. F datasheet, page 15. RoHS-compliant and halogen-free per Analog Devices' material declarations.
