Product details
Overview
LTC2050HVIS6#TRPBF from Analog Devices is a zero-drift operational amplifier in 6-lead 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.
For engineers reviewing the LTC2050HVIS6#TRPBF datasheet, LTC2050HVIS6#TRPBF pinout, LTC2050HVIS6#TRPBF application, or LTC2050HVIS6#TRPBF equivalent, key selection criteria include guaranteed ±3µV max offset over –40°C to 85°C, active-low shutdown (3µA standby), and compatibility with single-supply (2.7V–6V) or dual-supply (±5.5V) operation in space-constrained industrial sensor nodes.
Technical Context
The LTC2050HVIS6#TRPBF uses auto-zeroing architecture with a 7.5kHz internal sampling clock to cancel input offset and drift across temperature and common-mode voltage. Its input stage supports common-mode range 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 (SHDN) that places inputs and output in high-impedance state while reducing supply current to ≤3µA. Input bias current remains ultra-low (±1pA typical) across its specified operating range, and PSRR/CMRR exceed 130dB at DC, supporting stable performance in noisy industrial power domains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | ±0.5µV typical; enables sub-10µV system-level DC error in precision bridge amplifiers without calibration. |
| Offset Drift | 10nV/°C typical; ensures <1µV total drift over full –40°C to 85°C range for uncalibrated medical sensors. |
| Input Noise | 1.5µVP-P (0.01Hz–10Hz); supports 20-bit+ resolution in low-frequency data acquisition systems. |
| Supply Range | 2.7V to ±5.5V; allows direct interface with ±5V analog front-ends or 3.3V/5V microcontroller systems. |
| Shutdown Current | ≤3µA; permits battery-powered instrumentation to achieve multi-year standby life. |
| Gain Bandwidth | 3MHz; sufficient for closed-loop gains up to 300 in anti-aliasing filters with <0.1% gain error. |
| Output Swing | Rail-to-rail into 2kΩ; delivers full dynamic range at both supply rails for ADC driver applications. |
Pinout & Package
Package: 6-lead Plastic TSOT-23 (S6), 1mm profile, JEDEC MO-193 compliant, thermal resistance θJA = 250°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT | Amplifier output | Capable of rail-to-rail swing into 2kΩ load; high-current drive avoids external buffers in sensor interfaces. |
| 2 - V– | Negative supply rail | Supports dual-supply operation down to –5.5V; also serves as reference for single-supply configurations. |
| 3 - +IN | Non-inverting input | Ultra-low bias current (±1pA typ) preserves accuracy in high-impedance pH or thermocouple circuits. |
| 4 - –IN | Inverting input | Matches +IN characteristics; enables precision differential amplification with matched resistor networks. |
| 5 - SHDN | Active-low shutdown control | Pulling low disables amplifier, reduces supply current to ≤3µA, and places all pins in high-Z state. |
| 6 - V+ | Positive supply rail | Accepts 2.7V–6V (single) or up to +5.5V (dual); internal regulation maintains performance across supply variation. |
Key Features
| Feature | Design Value |
|---|---|
| Zero-drift architecture | Auto-zeroing at 7.5kHz eliminates long-term drift and 1/f noise, enabling DC-stable gain blocks without periodic recalibration. |
| Rail-to-rail output | Swings within 1mV of both rails into 2kΩ, maximizing ADC utilization and eliminating level-shifting components. |
| High PSRR/CMRR | ≥130dB at DC rejects supply ripple and common-mode interference in motor-drive or power-supply monitoring circuits. |
| Extended temperature grade | Specified from –40°C to +85°C (HVI suffix), qualifying for industrial control cabinets and automotive under-hood modules. |
| Low-profile SOT-23 | 1mm height enables placement beneath connectors or in stacked PCB assemblies where Z-height is constrained. |

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 |
|---|---|---|---|
| LTC2051IS8#PBF | Dual-channel version in SO-8; higher supply current (1.6mA per amp); no shutdown pin. | Suitable for dual-sensor systems (e.g., differential pressure + temperature) but lacks power-gating capability. | Select when two matched amplifiers are needed and board area permits SO-8; avoid if shutdown or space constraints apply. |
| LTC1150CS8#PBF | Higher voltage rating (±18V); larger offset (±5µV max); no shutdown; SO-8 only. | Targeted at high-voltage industrial transducers (e.g., piezoelectric sensors) where ±15V supplies are standard. | Choose only for ±15V systems requiring >10V output swing; not suitable for low-voltage or battery-powered designs. |
Compared with LTC2050HVIS6#TRPBF, LTC2051IS8#PBF offers channel density at the cost of power efficiency and shutdown control, while LTC1150CS8#PBF trades precision and low-voltage operation for extended supply range-making LTC2050HVIS6#TRPBF optimal for compact, battery-aware, high-accuracy DC signal chains.

FAQ
What is the maximum input common-mode voltage range for LTC2050HVIS6#TRPBF?
The LTC2050HVIS6#TRPBF supports an input common-mode voltage range from V– to (V+ – 1.3V) under typical conditions. For example, with ±5V supplies, this spans –5V to +3.7V; with a 5V single supply, it covers 0V to +3.7V. This extended range enables direct interfacing with grounded sensors and bridges without level-shifting circuitry, preserving signal integrity in LTC2050HVIS6#TRPBF-based designs.
Does LTC2050HVIS6#TRPBF require external capacitors for stability?
No, the LTC2050HVIS6#TRPBF is unity-gain stable and does not require external compensation capacitors. Its internal architecture ensures phase margin >60° across all gains and load conditions up to 100pF capacitance. However, a 0.1µF bypass capacitor placed close to the V+ and V– pins is mandatory for optimal PSRR and noise performance-this requirement is explicitly validated in the LTC2050HVIS6#TRPBF datasheet layout guidelines.
How does the shutdown feature affect the input/output states of LTC2050HVIS6#TRPBF?
When the SHDN pin of LTC2050HVIS6#TRPBF is pulled low, the amplifier enters shutdown mode: supply current drops to ≤3µA, internal clocking halts, and both input terminals (+IN and –IN) plus the output (OUT) enter high-impedance states. This prevents loading of upstream sensors or downstream circuitry. The device resumes normal operation within 2ms after SHDN is returned high, as confirmed by transient response testing in the LTC2050HVIS6#TRPBF datasheet.
Is LTC2050HVIS6#TRPBF qualified for automotive applications?
The LTC2050HVIS6#TRPBF is not AEC-Q100 qualified. Only the automotive-grade variants-marked with #W suffix (e.g., LTC2050HVMPS6#WTRPBF)-undergo controlled manufacturing and reliability testing for automotive use. LTC2050HVIS6#TRPBF is rated for –40°C to +85°C and intended for industrial and medical applications; its qualification scope excludes automotive under-hood or safety-critical systems per Analog Devices' official ordering information.
What is the typical input bias current of LTC2050HVIS6#TRPBF at 25°C and how does it vary with temperature?
The LTC2050HVIS6#TRPBF exhibits ±1pA typical input bias current at 25°C, with a maximum of ±50pA over its full –40°C to +85°C range. Unlike conventional op amps, its bias current remains exceptionally stable below 70°C due to auto-zeroing architecture; above 85°C, ESD diode leakage causes gradual increase-but still stays within datasheet limits. This behavior is documented in Figure G11 of the LTC2050HVIS6#TRPBF datasheet.
