Product details
Overview
LTC2050HVIS6#TRMPBF from Analog Devices is a zero-drift operational amplifier in a 6-lead SOT-23 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) input-referred noise, and rail-to-rail output swing into 2kΩ loads-enabling high-accuracy thermocouple amplification and strain gauge measurement.
For engineers reviewing the LTC2050HVIS6#TRMPBF datasheet, LTC2050HVIS6#TRMPBF pinout, LTC2050HVIS6#TRMPBF application, or LTC2050HVIS6#TRMPBF equivalent, key selection criteria include guaranteed ±3µV max offset, shutdown capability (active-low SHDN), –40°C to +85°C operating range, and compatibility with single-supply (2.7V–6V) or dual-supply (±5.5V) configurations.
Technical Context
The LTC2050HVIS6#TRMPBF 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– to (V+ – 1.3V), and its enhanced output stage drives rail-to-rail into 2kΩ loads with 140dB open-loop gain and 3MHz gain-bandwidth product.
It integrates an active-low shutdown pin (Pin 5), reducing supply current to ≤15µA in shutdown mode while placing inputs and output in high-impedance state. Input bias current remains ultra-low (±1pA typical) across temperature, and PSRR/CMRR exceed 130dB, ensuring stability in noisy industrial environments.
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 range |
| Input Noise (0.01Hz–10Hz) | 1.5µVP-P - supports high-resolution data acquisition without 1/f noise degradation |
| Supply Range | 2.7V to ±5.5V - operates from single 3V/5V rails or dual ±5V supplies |
| Gain Bandwidth Product | 3MHz - sufficient for closed-loop gains up to 1000 at DC–3kHz bandwidth |
| Output Swing | Rail-to-rail into 2kΩ - delivers full dynamic range with minimal headroom loss |
| Shutdown Current | ≤15µA - enables low-power sleep modes in battery-operated instrumentation |
Pinout & Package
Package: 6-lead Plastic TSOT-23 (S6), 1.90mm × 2.80mm × 0.85mm profile, JEDEC MO-193 compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: OUT | Amplifier output | Capable of rail-to-rail swing into 2kΩ load; high-impedance during shutdown |
| 2: V– | Negative supply rail | Reference for internal circuitry; supports ground or negative voltage |
| 3: +IN | Non-inverting input | Low-bias-current node (±1pA typ); ESD-protected, sensitive to >700V transients |
| 4: –IN | Inverting input | Matches +IN in bias current and CMVR; used for feedback and differential sensing |
| 5: SHDN | Active-low shutdown control | Pull low to enter shutdown (≤15µA ICC); float or tie high for normal operation |
| 6: V+ | Positive supply rail | Accepts 2.7V–6V (single) or +5.5V (dual); powers internal auto-zero clock and amplifier core |
Key Features
| Feature | Design Value |
|---|---|
| Zero-drift architecture | Auto-zeroing at 7.5kHz eliminates long-term offset drift and 1/f noise without external components |
| Rail-to-rail output | Drives to within 1mV of either rail into 10kΩ, enabling full utilization of ADC input range |
| High PSRR/CMRR | ≥130dB over DC–100Hz - rejects power supply ripple and common-mode interference in noisy systems |
| Extended temperature grade | Specified from –40°C to +85°C - qualified for industrial and automotive under-hood applications |
| Low input bias current | ±1pA typical at 25°C - minimizes voltage error across high-impedance sensor sources (e.g., pH electrodes) |

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 (±0.5µV) and noise (1.5µVP-P), but no shutdown pin | Requires two matched amplifiers per board; lacks power-gating capability | Choose when dual-channel operation is needed and space allows SO-8 footprint |
| AD8628ARZ | Single zero-drift op amp; 1µV max offset, 0.5µVP-P noise (0.1–10Hz), no shutdown, SO-8 only | Lower noise but no SHDN; not qualified for –40°C to +85°C extended temp | Prefer for ultra-low-noise, non-shutdown applications where SO-8 is acceptable |
Compared with LTC2050HVIS6#TRMPBF, LTC2051HS8#PBF offers dual functionality at the cost of shutdown and SOT-23 compactness, while AD8628ARZ trades shutdown and temperature rating for marginally lower noise in a larger package.

FAQ
What is the maximum input offset voltage specification for LTC2050HVIS6#TRMPBF?
The LTC2050HVIS6#TRMPBF has a guaranteed maximum input offset voltage of ±3µV over its –40°C to +85°C operating temperature range. This specification is validated per Analog Devices' production test flow and applies to all H-grade (high-temperature) variants including LTC2050HVIS6#TRMPBF, making it suitable for precision applications where sub-10µV system-level DC error budgets are required.
Does LTC2050HVIS6#TRMPBF support dual-supply operation?
Yes, LTC2050HVIS6#TRMPBF supports dual-supply operation from ±2.7V up to ±5.5V. As part of the LTC2050HV series, it maintains full performance-including ±3µV max offset, 1.5µVP-P noise, and rail-to-rail output-across this extended supply range, unlike the standard LTC2050 which is limited to single 2.7V–6V operation.
How does the shutdown feature work on LTC2050HVIS6#TRMPBF?
The LTC2050HVIS6#TRMPBF features an active-low shutdown pin (Pin 5). When pulled below V– + 0.5V, the device enters shutdown mode, reducing supply current to ≤15µA, halting the internal 7.5kHz auto-zero clock, and placing both inputs and the output in high-impedance state. The pin may be left floating or tied to V+ to enable normal operation.
What is the input common-mode voltage range for LTC2050HVIS6#TRMPBF?
The LTC2050HVIS6#TRMPBF supports an input common-mode voltage range from V– to (V+ – 1.3V) across its full operating temperature range. For example, with ±5V supplies, inputs operate from –5V to +3.7V; with a 5V single supply, inputs operate from 0V to +3.7V-enabling direct interfacing with grounded sensors and level-shifted signals without external biasing.
Is LTC2050HVIS6#TRMPBF qualified for automotive applications?
No, LTC2050HVIS6#TRMPBF is not automotive-qualified. It is rated for –40°C to +85°C (I-grade) and carries no AEC-Q100 certification. For automotive use, Analog Devices offers the LTC2050HVMPS6#WPBF variant, which is AEC-Q100 qualified, rated for –55°C to +150°C, and manufactured under controlled automotive processes-distinct from the commercial-grade LTC2050HVIS6#TRMPBF.
