Product details
Overview
LTC2050CS5#TRPBF from Analog Devices is a zero-drift operational amplifier in a 5-lead TSOT-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 interfaces.
For engineers reviewing the LTC2050CS5#TRPBF datasheet, LTC2050CS5#TRPBF pinout, LTC2050CS5#TRPBF application, or LTC2050CS5#TRPBF equivalent, this page provides verified specifications, S5-package terminal mapping, real-world use cases in medical instrumentation and electronic scales, and two validated alternative parts with documented functional trade-offs.
Technical Context
The LTC2050CS5#TRPBF employs auto-zeroing architecture with a 7.5kHz internal sampling clock to eliminate DC offset and drift over temperature and supply variations. Its input stage supports common-mode voltage from V– up to 1V below V+, and its enhanced output stage drives rail-to-rail into 2kΩ loads with 140dB open-loop gain.
It operates from a single 2.7V to 6V supply, consumes 800µA typical quiescent current, and features no shutdown pin (S5 package lacks SHDN). Input bias current is ±20pA typical at 25°C, and PSRR/CMRR exceed 130dB across the operating range.
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 –40°C to 125°C operating range |
| Input Noise (0.01Hz–10Hz) | 1.5µVP-P - supports high-resolution data acquisition without 1/f noise degradation |
| Gain Bandwidth Product | 3MHz - sufficient for closed-loop gains up to 1000 at DC–3kHz bandwidth |
| Supply Voltage Range | 2.7V to 6V single supply - compatible with 3.3V and 5V systems without level-shifting |
| Output Swing | Rail-to-rail into 2kΩ - delivers full dynamic range at both supply extremes for low-voltage ADC interfacing |
| PSRR / CMRR | ≥130dB typical - rejects power supply ripple and common-mode interference in noisy industrial environments |
Pinout & Package
Package: 5-Lead Plastic TSOT-23 (S5), 1mm profile, JEDEC MO-193 compliant, θJA = 250°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT | Amplifier output | Capable of rail-to-rail swing into 2kΩ; high-impedance in shutdown (not applicable to S5) |
| 2 - V– | Negative supply rail | Ground reference for single-supply operation; extends common-mode range to V– |
| 3 - +IN | Non-inverting input | Low-bias, low-noise node; ESD-protected but sensitive to >700V transients |
| 4 - –IN | Inverting input | Matches +IN in offset and drift; used for feedback and differential configurations |
| 5 - V+ | Positive supply rail | Accepts 2.7V–6V; supplies internal auto-zeroing circuitry and output stage |
Key Features
| Feature | Design Value |
|---|---|
| Zero-drift architecture | Auto-zeroing at 7.5kHz eliminates long-term DC drift and thermal hysteresis in precision measurement |
| Rail-to-rail output | Drives loads down to 2kΩ from rail to rail, maximizing dynamic range for low-voltage ADCs |
| Ultra-low 1/f noise | 1.5µVP-P (0.01Hz–10Hz) enables stable DC measurements in thermocouple and bridge applications |
| High CMRR/PSRR | ≥130dB minimizes error from supply ripple and common-mode interference in industrial sensors |
| Extended temperature grade | H-suffix variant rated –40°C to 125°C; C-suffix (LTC2050CS5#TRPBF) specified 0°C to 70°C |
Applications
| Thermocouple Amplifiers | Electronic Scales |
|---|---|

| Medical Instrumentation | Strain Gauge Amplifiers |
Use Scenario: Biopotential signal conditioning (ECG, EEG) requiring ultra-stable baseline and minimal DC drift. IC Role / Device Role / Timing Role: High-CMRR, low-input-bias amplifier for differential biosignal acquisition. Use Value: ≥130dB CMRR rejects 50/60Hz interference; ±20pA input bias avoids electrode polarization errors. | Use Scenario: Wheatstone bridge amplification in structural health monitoring with microstrain resolution. IC Role / Device Role / Timing Role: Precision DC amplifier with matched input terminals and low thermal EMF. Use Value: 0.5µV offset ensures <1µε resolution at 2mV/V sensitivity; low drift prevents zero-point drift during long-term monitoring. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LTC2051IMS8#TRPBF | Dual-channel version in MS8 package; same offset (±0.5µV), drift (10nV/°C), and noise (1.5µVP-P) | Requires PCB redesign for dual-amplifier use; adds channel matching benefit for instrumentation topologies | Select when dual amplifiers are needed in space-constrained designs where shared supply and layout simplify routing |
| LTC1050CS8#PBF | Higher supply current (1.2mA vs 0.8mA); wider supply range (4.75V–16V); guaranteed noise spec (1.8µVP-P) | Better suited for high-voltage single-supply systems (>6V); less optimal for battery-powered 3.3V applications | Choose for legacy 5V/12V industrial systems where higher supply headroom offsets slightly higher power consumption |
Compared with LTC2050CS5#TRPBF, LTC2051IMS8#TRPBF offers dual-channel integration at identical precision but requires different packaging and layout, while LTC1050CS8#PBF trades lower quiescent current for higher voltage capability-making it suitable only in non-battery, higher-supply applications.

FAQ
What is the maximum operating temperature for the LTC2050CS5#TRPBF?
The LTC2050CS5#TRPBF is specified for 0°C to 70°C ambient operating temperature. While the underlying die supports –40°C to 125°C (H-grade), the C-suffix marking confirms its tested and guaranteed performance within the commercial temperature range. Derating is required outside this range.
Does the LTC2050CS5#TRPBF include a shutdown pin?
No, the LTC2050CS5#TRPBF does not include a shutdown pin. Only the 6-lead SOT-23 (S6) and SO-8 (S8) variants of the LTC2050 family feature the active-low SHDN pin. The S5 package has five pins: OUT, V–, +IN, –IN, and V+.
What is the input common-mode voltage range of the LTC2050CS5#TRPBF?
The LTC2050CS5#TRPBF supports an input common-mode voltage range from V– up to typically 1V below V+. For example, with a 5V single supply (V+ = 5V, V– = 0V), the usable input range is 0V to 4V-enabling direct interfacing with most resistive sensors and DAC outputs.
Can the LTC2050CS5#TRPBF drive capacitive loads?
The LTC2050CS5#TRPBF is stable with capacitive loads ≤50pF without external compensation. Driving larger capacitive loads (e.g., ADC inputs, cables) requires isolation resistance (≥100Ω) in series with the output or a small series resistor plus feedback capacitor to maintain phase margin and prevent oscillation.
Is the LTC2050CS5#TRPBF RoHS-compliant and lead-free?
Yes, the LTC2050CS5#TRPBF is RoHS-compliant and features a lead-free finish, as indicated by the "#TRPBF" suffix per Analog Devices' ordering nomenclature. It meets JEDEC J-STD-020 moisture sensitivity level 1 and is qualified for reflow soldering per IPC/JEDEC J-STD-020.
