Product details
Overview
LTC2050HVHS6#TRPBF from Analog Devices is a high-voltage zero-drift operational amplifier in a 6-lead SOT-23 package, designed for precision DC-coupled signal conditioning. It operates from ±2.7V to ±5.5V supplies, delivers 140dB open-loop gain, 1.5µVP-P (0.01Hz–10Hz) input-referred noise, and achieves ±3µV max input offset voltage with ±30nV/°C max drift - enabling thermocouple amplification and strain gauge measurement at industrial temperature ranges (–40°C to 125°C).
For engineers reviewing the LTC2050HVHS6#TRPBF datasheet, LTC2050HVHS6#TRPBF pinout, LTC2050HVHS6#TRPBF application, or LTC2050HVHS6#TRPBF equivalent, this page provides verified specifications, validated S6-package terminal mapping, real-world use cases in low-side current sensing and high-resolution data acquisition, and two confirmed alternative parts with documented functional and thermal differences.
Technical Context
The LTC2050HVHS6#TRPBF employs auto-zeroing architecture with a 7.5kHz internal sampling clock to eliminate input offset and drift over time, temperature, and supply variation. Its rail-to-rail output stage drives 2kΩ loads to both rails, while input common-mode range extends from V– to (V+ – 1.3V), supporting single-ended and differential bridge configurations.
It integrates an active shutdown pin (SHDN, Pin 5) that reduces supply current to ≤3µA and places inputs/outputs in high-impedance state. PSRR and CMRR exceed 130dB across DC–10kHz, ensuring immunity to supply and common-mode disturbances in noisy industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | ±2.7V to ±5.5V - supports bipolar sensor interfaces and dual-rail industrial systems without level-shifting. |
| Input Offset Voltage (max) | ±3µV - enables sub-10µV system-level DC accuracy in 24-bit DAQ front-ends. |
| Offset Drift (max) | ±30nV/°C - ensures <1µV total drift over –40°C to 125°C operating range. |
| Input Noise (0.01Hz–10Hz) | 1.5µVP-P - preserves resolution in low-frequency precision measurements (e.g., thermocouples, load cells). |
| Open-Loop Gain | 140dB (typ) - guarantees <0.001% gain error in closed-loop gains up to 1000 with stable feedback. |
| Gain Bandwidth Product | 3MHz - supports bandwidth-critical precision filtering (e.g., anti-aliasing) while retaining DC accuracy. |
| Shutdown Current | ≤3µA - enables ultra-low-power sleep modes in battery-backed instrumentation. |
Pinout & Package
Package: 6-lead Plastic TSOT-23 (S6), 1.90mm × 2.90mm × 0.95mm profile, RoHS-compliant, lead-free finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT | Amplifier output | Rail-to-rail capable; drives ≥2kΩ load to both supply rails with <10mV saturation. |
| 2 - V– | Negative supply connection | Reference for internal biasing; supports operation down to –5.5V. |
| 3 - +IN | Non-inverting input | Low-input-bias-current node (±50pA typ); optimized for high-impedance sensor interfaces. |
| 4 - –IN | Inverting input | Differential input pair node; matched to +IN for CMRR >130dB. |
| 5 - SHDN | Active-low shutdown control | Pull ≤(V– + 0.5V) to enter shutdown; draws ≤3µA and disables internal clocking. |
| 6 - V+ | Positive supply connection | Supports up to +5.5V; PSRR >130dB ensures stability under supply ripple. |
Key Features
| Feature | Design Value |
|---|---|
| Zero-drift architecture | Auto-zeroing at 7.5kHz eliminates long-term offset drift - critical for unattended monitoring systems. |
| Rail-to-rail output | Swings within 10mV of V+ and V– into 2kΩ - maximizes dynamic range in single-supply data loggers. |
| High PSRR/CMRR | ≥130dB over DC–10kHz - rejects power supply noise and common-mode interference in motor-drive environments. |
| Extended temperature grade | Specified from –40°C to 125°C - qualified for under-hood automotive and industrial control applications. |
| Shutdown mode | Reduces quiescent current to ≤3µA and isolates I/O pins - enables energy-efficient wake-on-event designs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LTC2051HS8#PBF | Dual-channel version in SO-8; same offset (±3µV), drift (±30nV/°C), and noise (1.5µVP-P); higher supply current (1.6mA/channel). | Requires PCB redesign for dual-amplifier functions (e.g., instrumentation + reference buffer); no shutdown pin per channel. | Select when dual-channel functionality is needed and board space permits SO-8 footprint; verify thermal derating at 125°C. |
| LTC1150CS8#PBF | Higher voltage rating (±18V), but higher offset (±10µV), higher drift (±100nV/°C), and higher noise (3µVP-P); no shutdown. | Suitable for ±15V legacy systems but lacks DC precision for thermocouple or strain gauge use below 100µV signals. | Choose only if ±15V operation is mandatory and <10µV offset is acceptable; avoid for new high-accuracy designs. |
Compared with LTC2050HVHS6#TRPBF, LTC2051HS8#PBF offers channel count at the cost of layout change and higher quiescent power, while LTC1150CS8#PBF trades DC precision for wider supply range - making LTC2050HVHS6#TRPBF optimal for compact, low-drift, shutdown-capable industrial sensing.

FAQ
What is the maximum supply voltage for LTC2050HVHS6#TRPBF?
The LTC2050HVHS6#TRPBF supports a total supply voltage (V+ to V–) up to 12V, corresponding to ±5.5V operation. Absolute maximum ratings specify V+ to V– ≤12V; exceeding this risks permanent damage. Operation at ±5.5V is fully characterized and supported across the –40°C to 125°C temperature range for LTC2050HVHS6#TRPBF.
Does LTC2050HVHS6#TRPBF include a shutdown feature?
Yes, LTC2050HVHS6#TRPBF includes an active-low shutdown pin (SHDN, Pin 5). When pulled to V– (or ≤V– + 0.5V), it disables internal circuitry, reducing supply current to ≤3µA and placing both inputs and the output in high-impedance state. This feature is confirmed in the datasheet's Electrical Characteristics table and Shutdown section.
What is the input offset voltage specification for LTC2050HVHS6#TRPBF?
The LTC2050HVHS6#TRPBF has a maximum input offset voltage of ±3µV at TA = 25°C and over the full operating temperature range (–40°C to 125°C), as specified in the H-suffix electrical characteristics table. Typical offset is ±0.5µV, and long-term drift is limited to 50nV/√month - all guaranteed for the LTC2050HVHS6#TRPBF variant.
Is LTC2050HVHS6#TRPBF suitable for low-side current sensing?
Yes, LTC2050HVHS6#TRPBF is explicitly validated for low-side current sensing, as shown in Typical Application TA08. Its input common-mode range extends to V–, enabling direct amplification of shunt voltages referenced to the negative rail. With ±3µV offset and rail-to-rail output, LTC2050HVHS6#TRPBF achieves <1mA resolution using a 3mΩ shunt at ±5V supplies.
What package type does LTC2050HVHS6#TRPBF use?
LTC2050HVHS6#TRPBF uses the 6-lead Plastic TSOT-23 package (S6), measuring 1.90mm × 2.90mm × 0.95mm. This low-profile surface-mount package is documented in the LTC2050/LTC2050HV Rev F datasheet Package Description section and confirmed by order code "HS6" and marking "LTAEK".
