Product details
Overview
LTC2050HVCS8#PBF from Analog Devices is a zero-drift operational amplifier in an 8-lead SOIC 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 LTC2050HVCS8#PBF datasheet, LTC2050HVCS8#PBF pinout, LTC2050HVCS8#PBF application, or LTC2050HVCS8#PBF equivalent, key selection criteria include its ±5.5V dual-supply operation, 140dB open-loop gain, shutdown capability (active-low), and guaranteed 0°C to 70°C temperature range with AEC-Q100-compliant variants available.
Technical Context
The LTC2050HVCS8#PBF employs auto-zeroing architecture with a 7.5kHz internal sampling clock to eliminate input offset and drift across temperature, supply, and common-mode voltage variations. Its input stage supports common-mode range from V– to (V+ – 1.3V), and the output stage drives rail-to-rail into 2kΩ loads with 2V/µs slew rate and 3MHz gain-bandwidth product.
It features integrated shutdown control (Pin 5), delivering <3µA quiescent current in disabled state. PSRR and CMRR exceed 130dB over DC–100Hz, ensuring robust rejection of supply and common-mode disturbances in low-frequency precision systems.
Key Specifications

|---|---|
| Input Offset Voltage | ±3µV max - enables sub-10µV system-level DC error in 16-bit DAQ front-ends |
| Offset Drift | ±30nV/°C max - ensures <1µV total drift over 0°C–70°C operating range |
| Noise (0.01Hz–10Hz) | 1.5µVP-P - supports <16-bit ENOB in DC-sensing applications without external filtering |
| Supply Range | 2.7V to ±5.5V - compatible with ±5V industrial rails and single 5V logic supplies |
| Open-Loop Gain | 140dB typ - provides >100dB loop gain at 100mV output error for high-precision closed-loop designs |
| CMRR / PSRR | ≥130dB typ - rejects >1M:1 common-mode or supply ripple in sensor bridges and current sense |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LTC2051IS8#PBF | Dual-channel version in same SO-8 package; 0.5µV offset, 1.5µVP-P noise, but no shutdown pin | Preferred where space-constrained dual-sensor conditioning is required without independent channel shutdown | Select when two matched amplifiers are needed and shutdown is not required per channel |
| LTC1150CS8#PBF | Higher voltage rating (±18V), 5µV max offset, 3µVP-P noise, no auto-zeroing-uses chopper-stabilized architecture | Better suited for ±15V industrial control loops where higher supply headroom outweighs drift performance | Choose for legacy ±15V systems needing >100dB CMRR but tolerating higher drift and noise than LTC2050HVCS8#PBF |
Compared with LTC2050HVCS8#PBF, LTC2051IS8#PBF offers dual-channel integration at identical precision but lacks shutdown; LTC1150CS8#PBF trades zero-drift performance for wider supply range and higher voltage tolerance-making it suitable for different rail architectures rather than direct replacement.

FAQ
What is the maximum supply voltage for LTC2050HVCS8#PBF?
The LTC2050HVCS8#PBF supports a total supply voltage of up to 12V, meaning it can operate with dual supplies of ±5.5V or single supplies up to 12V. Absolute maximum ratings specify V+ to V– ≤12V; exceeding this risks permanent damage. Operation at ±5V is fully characterized and recommended for optimal PSRR and CMRR performance.
Does LTC2050HVCS8#PBF have rail-to-rail input capability?
No, LTC2050HVCS8#PBF does not feature rail-to-rail input. Its input common-mode voltage range extends from V– to (V+ – 1.3V) - for example, with ±5V supplies, inputs must stay between –5V and +3.7V. This limitation is intentional to maintain high CMRR and low input bias current across the specified range.
How does the shutdown function work on LTC2050HVCS8#PBF?
The LTC2050HVCS8#PBF uses Pin 5 (SHDN) as an active-low shutdown control. When pulled below V– + 0.5V, the device enters shutdown mode, reducing supply current to ≤3µA, halting internal clocking, and placing inputs and output in high-impedance state. During normal operation, SHDN must be tied to V+ or left floating.
Is LTC2050HVCS8#PBF suitable for automotive applications?
The base LTC2050HVCS8#PBF is rated for 0°C to 70°C and is not automotive-qualified. However, Analog Devices offers AEC-Q100 qualified variants such as LTC2050HVMPS6#WPBF (–55°C to 150°C, TSOT-23-6) and LTC2050HVHS8#WPBF (–40°C to 125°C, SO-8). These share identical electrical specs but undergo additional automotive reliability testing.
What is the typical input bias current of LTC2050HVCS8#PBF?
The LTC2050HVCS8#PBF exhibits ±1pA typical input bias current (±50pA max) at 25°C with ±5V supplies. This ultra-low value results from its auto-zeroing architecture and is critical for high-impedance sensor interfaces like pH electrodes or piezoresistive bridges, where bias current-induced errors must remain below 100nV.
