Product details
Overview
LTC2050HS6#TRPBF from Analog Devices is a zero-drift operational amplifier in a 6-lead SOT-23 package, designed for high-precision DC-critical applications including thermocouple amplification and strain gauge signal conditioning. It delivers 0.5µV typical input offset voltage, 10nV/°C typical offset drift, 1.5µVP-P (0.01Hz–10Hz) input-referred noise, 140dB open-loop gain, and rail-to-rail output swing into 2kΩ loads.
For engineers reviewing the LTC2050HS6#TRPBF datasheet, LTC2050HS6#TRPBF pinout, LTC2050HS6#TRPBF application, or LTC2050HS6#TRPBF equivalent, this page provides verified specifications, thermal-grade packaging context (–40°C to 125°C), shutdown functionality, and application-specific design meaning for low-drift sensor front-ends.
Technical Context
The LTC2050HS6#TRPBF employs auto-zeroing architecture with a 7.5kHz internal sampling clock to continuously correct input offset and drift. Its input stage supports common-mode voltage from V– up to 1V below V+, enabling single-supply operation down to 2.7V while maintaining >130dB PSRR and CMRR across temperature.
It integrates an active-low shutdown pin (Pin 5) that reduces supply current to ≤15µA and places inputs/outputs in high-impedance state. Output stage drives 2kΩ loads rail-to-rail with <10mV low-side swing and 2V/µs slew rate, supporting stable closed-loop performance in precision instrumentation filters and current-sense circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | ±3µV max - enables sub-10µV system-level DC error in 16-bit+ data acquisition without calibration. |
| Offset Drift | ±30nV/°C max - ensures <1µV total drift over full –40°C to 125°C operating range, critical for automotive and industrial sensors. |
| Noise (0.01Hz–10Hz) | 1.5µVP-P - supports high-resolution thermocouple and bridge measurements with <0.1°C resolution at 10Hz bandwidth. |
| Open-Loop Gain | 140dB typical - guarantees <0.001% gain error in unity-gain buffer or G=100 configurations with 10kΩ feedback networks. |
| Supply Range | 2.7V to 6V - allows direct interface with 3.3V microcontrollers and battery-powered portable instrumentation. |
| Shutdown Current | ≤15µA - enables power-gating in energy-constrained IoT sensor nodes without external switches. |
| CMRR / PSRR | >130dB typical - rejects >1M:1 common-mode and supply noise, essential for accurate low-side current sensing in noisy environments. |
Pinout & Package
Package: 6-lead Plastic TSOT-23 (S6), 1mm profile, JEDEC MO-193 compliant, rated for –40°C to 125°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: OUT | Amplifier output | Capable of rail-to-rail swing into 2kΩ; requires ≥100pF load capacitance stability margin per datasheet layout guidance. |
| 2: V– | Negative supply rail | Reference for input common-mode range (extends to V–); must be decoupled with 0.1µF ceramic near pin. |
| 3: +IN | Non-inverting input | Ultra-low bias current (±75pA max) preserves accuracy in high-impedance sensor interfaces like thermocouples. |
| 4: –IN | Inverting input | Matches +IN characteristics; differential input capacitance 1.7pF limits bandwidth in capacitive source applications. |
| 5: SHDN | Active-low shutdown control | Pull ≤V– + 0.5V to enter shutdown; floating or VIH ≥ V+ – 0.5V enables normal operation. |
| 6: V+ | Positive supply rail | Supports up to 6V; PSRR >130dB minimizes sensitivity to digital supply ripple in mixed-signal systems. |
Key Features
| Feature | Design Value |
|---|---|
| Zero-drift architecture | Auto-zeroing at 7.5kHz eliminates long-term drift and 1/f noise, enabling true DC accuracy without periodic recalibration. |
| Rail-to-rail output | Swings within 10mV of both rails into 2kΩ, maximizing dynamic range in single-supply 3.3V systems. |
| Extended temperature grade | H-suffix guarantees –40°C to 125°C operation, qualified for under-hood automotive and industrial control environments. |
| Low-power shutdown | Reduces quiescent current to ≤15µA while disabling internal clock and placing I/O in high-Z - ideal for duty-cycled sensor nodes. |
| High PSRR/CMRR | 130dB rejection of supply and common-mode interference ensures stable gain in noisy motor-drive or power-supply monitoring circuits. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar zero-drift op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LTC2051HS8#PBF | Dual-channel version in SO-8; same offset/drift specs but higher 1.6mA supply current per amplifier. | Requires PCB real estate for dual-channel use; no shutdown pin on individual amps. | Choose when dual amplifiers are needed in same thermal zone and space permits SO-8. |
| LTC1150CS8#PBF | Higher voltage (±18V) operation; 5µV max offset, 100nV/°C drift, 3.5µVP-P noise - less precise at DC. | Targeted at industrial ±15V systems; not suitable for 3.3V/5V low-voltage sensor nodes. | Choose only for legacy ±15V designs where extended supply range outweighs drift/noise penalties. |
Compared with LTC2050HS6#TRPBF, LTC2051HS8#PBF offers channel density at cost of shutdown control and higher quiescent current, while LTC1150CS8#PBF trades DC precision for high-voltage robustness - neither matches the LTC2050HS6#TRPBF's combination of ultra-low drift, rail-to-rail output, and 6-lead SOT-23 thermal-grade packaging.

FAQ
What is the maximum operating temperature range for the LTC2050HS6#TRPBF?
The LTC2050HS6#TRPBF is specified for operation from –40°C to 125°C, with guaranteed performance across this full range per its H-suffix qualification. This makes it suitable for under-hood automotive, industrial control, and outdoor instrumentation applications where ambient temperatures exceed standard commercial grades.
Does the LTC2050HS6#TRPBF include a shutdown function, and how is it controlled?
Yes, the LTC2050HS6#TRPBF includes an active-low shutdown pin (Pin 5). Pulling SHDN ≤ V– + 0.5V places the device in shutdown mode, reducing supply current to ≤15µA and placing inputs and output in high-impedance state. Leaving SHDN floating or driving it ≥ V+ – 0.5V enables normal operation.
What is the input offset voltage specification for the LTC2050HS6#TRPBF, and why does it matter in precision designs?
The LTC2050HS6#TRPBF has a maximum input offset voltage of ±3µV. This ultra-low value minimizes DC error in high-gain stages - for example, in a G=1000 strain gauge amplifier, it contributes only ±3mV output error, enabling sub-0.01% accuracy without trimming or software correction.
Can the LTC2050HS6#TRPBF drive capacitive loads, and what layout guidance applies?
The LTC2050HS6#TRPBF is stable with ≥100pF capacitive loads when using recommended feedback network layouts. For larger loads, a small series resistor (10–50Ω) between output and capacitor is advised. Layout best practices include short traces, local 0.1µF V+ and V– bypassing, and guarding the +IN/–IN nodes in high-impedance applications.
How does the LTC2050HS6#TRPBF compare to standard precision op amps in terms of 1/f noise and long-term drift?
Unlike standard precision op amps, the LTC2050HS6#TRPBF uses auto-zeroing to eliminate 1/f noise and reduce long-term drift to ±30nV/°C max. Its 1.5µVP-P (0.01Hz–10Hz) noise and <50nV/√month long-term drift make it uniquely suited for DC-stable applications such as electronic scales and medical diagnostics where baseline drift degrades measurement integrity over time.
