Product details
Overview
LTC2050HVCS6#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 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 LTC2050HVCS6#TRMPBF datasheet, LTC2050HVCS6#TRMPBF pinout, LTC2050HVCS6#TRMPBF application, or LTC2050HVCS6#TRMPBF equivalent, key selection criteria include its ±5.5V dual-supply operation, active-low shutdown capability, extended common-mode input range (V– to V+ – 1.3V), and guaranteed 3µV max offset over 0°C to 70°C.
Technical Context
The LTC2050HVCS6#TRMPBF uses auto-zeroing architecture with a 7.5kHz internal sampling clock to eliminate input offset and drift across temperature and supply variations. Its input stage supports common-mode voltages from V– up 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.
Shutdown functionality is implemented via Pin 5 (SHDN), which reduces supply current to ≤15µA when pulled low. Input bias current remains ultra-low (±1pA typ) across its operating range, and PSRR/CMRR exceed 130dB, ensuring robust performance in noisy industrial sensor front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | ±0.5µV typical - enables sub-10µV system-level DC error in precision instrumentation |
| Offset Drift | 10nV/°C typical - ensures <1µV total drift over 100°C ambient change |
| 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 - accommodates bipolar sensor interfaces and single/dual supply flexibility |
| Gain Bandwidth Product | 3MHz - allows stable closed-loop gains up to ~300 at 10kHz signal bandwidth |
| Output Swing | Rail-to-rail into 2kΩ - delivers full dynamic range with minimal headroom loss in low-voltage systems |
| Shutdown Current | ≤15µA - enables µA-level power budgeting in battery-powered or intermittent-sensing 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 impedance in shutdown mode |
| 2 V– | Negative supply rail | Reference for internal circuitry; supports true negative rail operation down to –5.5V |
| 3 +IN | Non-inverting input | Ultra-low bias current (±1pA typ); ESD-protected; common-mode range extends to V– |
| 4 –IN | Inverting input | Matches +IN in offset, drift, and bias; supports differential bridge configurations |
| 5 SHDN | Active-low shutdown control | Pull low to reduce supply current to ≤15µA; floats high for normal operation |
| 6 V+ | Positive supply rail | Accepts up to +5.5V; PSRR >130dB minimizes supply ripple coupling to output |
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 loads as low as 2kΩ to both rails, preserving full signal swing in 3.3V or ±5V systems |
| Extended common-mode range | Inputs operate from V– to V+ – 1.3V - supports direct connection to grounded sensors or shunt resistors |
| High PSRR/CMRR | ≥130dB over DC–100Hz - rejects supply noise and common-mode interference in noisy industrial environments |
| Low-power shutdown | Reduces quiescent current to ≤15µA while maintaining high-impedance I/O states for seamless system sleep/wake |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|

| LTC2051HS8#TRPBF | Dual-channel version in SO-8; shares same offset (±0.5µV), drift (10nV/°C), and noise (1.5µVP-P) specs but lacks shutdown pin | Optimized for space-constrained dual-sensor systems where channel count > pin count efficiency matters | Choose when two matched amplifiers are needed and shutdown is not required per channel |
Compared with LTC2050HVCS6#TRMPBF, LTC2050HVHS6#TRPBF offers wider temperature coverage without sacrificing precision, while LTC2051HS8#TRPBF provides dual-channel integration at the cost of shutdown control and increased footprint-making each suitable for distinct thermal, channel-count, and power-management requirements.

FAQ
What is the maximum supply voltage rating for the LTC2050HVCS6#TRMPBF?
The LTC2050HVCS6#TRMPBF has an absolute maximum total supply voltage (V+ to V–) of 12V. It operates over a recommended range of 2.7V to ±5.5V, supporting dual-supply configurations such as ±5V (10V total) or single-supply 5.5V with ground reference. Exceeding 12V risks permanent damage per Absolute Maximum Ratings.
Does the LTC2050HVCS6#TRMPBF support rail-to-rail input operation?
No, the LTC2050HVCS6#TRMPBF does not support rail-to-rail input. Its input common-mode voltage range extends from the negative supply (V–) up to typically V+ – 1.3V. For example, with ±5V supplies, inputs operate from –5V to +3.7V - sufficient for most grounded-sensor or shunt-based applications but not to the positive rail.
How does the shutdown feature affect the I/O pins of the LTC2050HVCS6#TRMPBF?
When the SHDN pin (Pin 5) is pulled low, the LTC2050HVCS6#TRMPBF enters shutdown mode: supply current drops to ≤15µA, internal clocking stops, and all I/O pins (OUT, +IN, –IN) enter high-impedance states. This prevents loading of external circuits and enables safe multiplexing or power-gating in multi-amplifier systems.
Can the LTC2050HVCS6#TRMPBF drive capacitive loads directly?
The LTC2050HVCS6#TRMPBF is not unity-gain stable with large capacitive loads. Driving >100pF directly may cause peaking or oscillation. For capacitive loads >50pF, use isolation resistance (e.g., 10–100Ω in series with output) or refer to Figure 8 (Gain/Phase vs Frequency) in the datasheet to verify phase margin at target closed-loop gain.
What is the input bias current specification for the LTC2050HVCS6#TRMPBF at 85°C?
At 85°C, the LTC2050HVCS6#TRMPBF exhibits input bias current of ±50pA maximum (typical ±7pA), as specified in the H-suffix electrical characteristics table. This remains exceptionally low compared to standard CMOS op amps and is critical for high-impedance sensor interfaces like piezoresistive bridges or pH electrodes.
