Product details
Overview
LTC2050IS6#TRMPBF from Analog Devices is a zero-drift operational amplifier in 6-lead SOT-23 (TSOT-23) package, designed for precision DC-coupled signal conditioning. It delivers 0.5µV typical input offset voltage, 10nV/°C 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 interfaces in industrial sensor systems.
For engineers reviewing the LTC2050IS6#TRMPBF datasheet, LTC2050IS6#TRMPBF pinout, LTC2050IS6#TRMPBF application, or LTC2050IS6#TRMPBF equivalent, key selection criteria include guaranteed ±3µV max offset, shutdown functionality (active-low SHDN), –40°C to 85°C operating range, and compatibility with single 2.7V–6V supplies-critical for low-power, high-stability analog front-ends.
Technical Context
The LTC2050IS6#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– up to V+ – 1.3V, and its enhanced output stage drives rail-to-rail into 2kΩ while maintaining >130dB PSRR and CMRR over temperature.
It integrates an active-low shutdown pin (Pin 5), reducing supply current to ≤3µA in sleep mode. Input bias current remains ultra-low (±75pA typ) across –40°C to 85°C, and long-term offset drift is specified at 50nV/√month-supporting decade-scale calibration stability in medical instrumentation and precision data acquisition.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | ±0.5µV typical; enables sub-10µV system-level DC error in 16-bit+ data acquisition paths |
| Offset Drift | 10nV/°C typical; ensures <1µV total drift over 100°C ambient range without recalibration |
| Input Noise (0.01–10Hz) | 1.5µVP-P; supports resolution of <1µV signals in slow-scan applications like electronic scales |
| Supply Range | 2.7V to 6V single supply; compatible with Li-ion, 3.3V, and 5V logic rails without level-shifting |
| Gain Bandwidth | 3MHz; sufficient for closed-loop gains up to 300 at 10kHz signal bandwidth |
| Shutdown Current | ≤3µA; allows power-gating in battery-operated portable instruments during idle periods |
| CMRR / PSRR | ≥130dB typical; rejects >1M:1 common-mode or supply ripple interference in noisy industrial environments |
Pinout & Package
Package: 6-lead Plastic TSOT-23 (S6), 1mm profile, JEDEC MO-193 compliant, footprint compatible with standard SOT-23 pick-and-place equipment.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: OUT | Amplifier output | Capable of rail-to-rail swing into 2kΩ load; drives ADC inputs or downstream buffers directly |
| 2: V– | Negative supply rail | Ground reference for single-supply operation; supports true 0V input common-mode down to V– |
| 3: +IN | Non-inverting input | Ultra-low bias current (±75pA typ) preserves accuracy in high-impedance sensor interfaces |
| 4: –IN | Inverting input | Matches +IN characteristics; enables precision differential gain configurations with matched feedback networks |
| 5: SHDN | Active-low shutdown control | Pull low to reduce supply current to ≤3µA; floats high for normal operation; no external pull-up required |
| 6: V+ | Positive supply rail | Accepts 2.7V–6V; internal regulation maintains stable core bias under supply ripple |
Key Features
| Feature | Design Value |
|---|---|
| Zero-drift architecture | Auto-zeroing at 7.5kHz eliminates thermal drift and 1/f noise-critical for DC-accurate RC filters and long-duration measurements |
| Rail-to-rail output | Swings within 1mV of both rails into 2kΩ, maximizing dynamic range when interfacing with 16-bit SAR ADCs |
| Extended input common-mode range | Operates with inputs from V– to V+ – 1.3V-supports direct connection to transducer bridges referenced to ground or mid-supply |
| Low 0.01–10Hz noise | 1.5µVP-P enables detection of microvolt-level thermocouple outputs without additional filtering or averaging |
| Shutdown mode | Reduces quiescent current to ≤3µA while placing inputs and output in high-impedance state-ideal for time-multiplexed sensor arrays |

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 |
|---|---|---|---|
| LTC2051IMS8#PBF | Dual-channel version in MS8 package; same offset (±0.5µV) and noise (1.5µVP-P), but no shutdown pin and higher supply current (1.5mA/channel) | Suitable for space-constrained dual-sensor systems where shutdown is unnecessary and board area permits MS8 footprint | Select when needing two matched amplifiers per package and can accommodate larger footprint and higher quiescent power |
| LTC1152CS8#PBF | Rail-to-rail input/output, ±15V supply capable, but higher offset (±5µV) and noise (3µVP-P); includes shutdown | Better suited for high-voltage industrial controls where input common-mode extends beyond 6V, but trades DC precision | Select only if rail-to-rail input is mandatory and ±15V operation required-accept reduced DC accuracy vs. LTC2050IS6#TRMPBF |
Compared with LTC2050IS6#TRMPBF, LTC2051IMS8#PBF offers channel density at the cost of shutdown and power efficiency, while LTC1152CS8#PBF expands voltage range and input flexibility but sacrifices 10× higher offset and double the noise-making LTC2050IS6#TRMPBF optimal for single-channel, ultra-precision, low-power DC applications.

FAQ
What is the maximum input offset voltage specification for LTC2050IS6#TRMPBF?
The maximum input offset voltage for LTC2050IS6#TRMPBF is ±3µV across the full –40°C to 85°C operating temperature range, as guaranteed in the datasheet's electrical characteristics table. This tight spec enables high-accuracy closed-loop designs without trimming, and the LTC2050IS6#TRMPBF achieves it via continuous auto-zeroing that cancels drift in real time.
Does LTC2050IS6#TRMPBF support single-supply operation?
Yes, LTC2050IS6#TRMPBF operates from a single 2.7V to 6V supply and features rail-to-rail output swing, allowing full-scale signal utilization even with ground-referenced inputs. Its input common-mode range extends from V– to V+ – 1.3V, making LTC2050IS6#TRMPBF ideal for single-supply sensor interfaces such as bridge amplifiers and thermocouple circuits.
How does the shutdown feature work on LTC2050IS6#TRMPBF?
The LTC2050IS6#TRMPBF includes an active-low shutdown pin (Pin 5). When pulled low, it reduces supply current to ≤3µA, halts internal clocking, and places both inputs and the output in high-impedance state. When left floating or driven high, LTC2050IS6#TRMPBF operates normally-no external pull-up resistor is required due to internal biasing.
What is the input noise performance of LTC2050IS6#TRMPBF in the 0.01Hz to 10Hz band?
LTC2050IS6#TRMPBF delivers 1.5µVP-P input-referred noise in the 0.01Hz to 10Hz band, measured with RS = 100Ω. This ultra-low flicker noise enables resolution of microvolt-level DC signals in applications like precision weighing and thermocouple measurement, and the LTC2050IS6#TRMPBF maintains this performance across its full –40°C to 85°C temperature range.
Is LTC2050IS6#TRMPBF qualified for automotive applications?
No-LTC2050IS6#TRMPBF is rated for –40°C to 85°C and is not AEC-Q100 qualified. For automotive use, Analog Devices offers the pin-compatible LTC2050HVMPS6#WTRPBF (–55°C to 150°C, AEC-Q100 Grade 1), which shares the same S6 package and core specifications but adds automotive reliability testing and controlled manufacturing. LTC2050IS6#TRMPBF remains appropriate for industrial and medical applications requiring high DC precision.
