Product details
Overview
LTC2050HVMPS6#TRMPBF from Analog Devices is a high-voltage, zero-drift operational amplifier in a 6-lead TSOT-23 package, designed for precision DC-critical applications including thermocouple amplification and strain gauge signal conditioning. It delivers 0.5µV typical input offset voltage, 10nV/°C typical offset drift, 1.5µVP-P (0.01Hz–10Hz) input-referred noise, and rail-to-rail output swing into 2kΩ loads with ±4.75V maximum output swing on ±5V supplies.
For engineers reviewing the LTC2050HVMPS6#TRMPBF datasheet, LTC2050HVMPS6#TRMPBF pinout, LTC2050HVMPS6#TRMPBF application, or LTC2050HVMPS6#TRMPBF equivalent, key selection criteria include extended temperature operation (–55°C to 150°C), AEC-Q100 qualification for automotive use, shutdown functionality (active-low SHDN), and guaranteed 3µV max offset voltage over full temperature range.
Technical Context
The LTC2050HVMPS6#TRMPBF employs auto-zeroing architecture with a 7.5kHz internal sampling clock to maintain near-zero DC offset across temperature, supply voltage, and common-mode variations. Its input stage supports common-mode voltage from V– to (V+ – 1.3V), and its enhanced output stage drives rail-to-rail into 2kΩ loads while maintaining >125dB large-signal voltage gain and >112dB CMRR at extended temperatures.
It operates from ±4.5V to ±5.5V dual supplies (9V to 11V total), draws 0.8mA typical supply current in active mode, and reduces to 1.3µA in shutdown. The device features an active-low shutdown pin (Pin 5), enabling low-power system states without external circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | ±0.5µV typical / ±3µV max - enables sub-10µV system-level DC error in precision sensor front-ends |
| Offset Drift | ±0.03µV/°C typical / ±0.10µV/°C max - ensures stable calibration over –55°C to 150°C automotive operating range |
| Noise (0.01Hz–10Hz) | 1.5µVP-P - supports high-resolution DC measurements in electronic scales and medical instrumentation |
| Supply Range | ±4.5V to ±5.5V - compatible with standard ±5V industrial and automotive power rails |
| Output Swing | ±4.75V min into 2kΩ - delivers full dynamic range at load without clipping in single-supply derived bipolar configurations |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LTC2050HVHS6#TRPBF | Same S6 package, but rated for –40°C to 125°C (not –55°C to 150°C); no AEC-Q100 qualification | Suitable for industrial control, not automotive under-hood use | Select when extended temperature and automotive qualification are unnecessary and cost optimization is prioritized |
| LTC2051HMS8#TRPBF | Dual-channel version in MS8 package; same offset specs but higher supply current (1.6mA/channel) and no shutdown pin | Used where space-constrained dual-sensor conditioning is needed, not single-channel low-power shutdown | Choose for dual-sensor systems requiring matched performance; avoid when shutdown or SOT-23 size is mandatory |
Compared with LTC2050HVHS6#TRPBF and LTC2050HVMPS6#TRMPBF, the LTC2050HVMPS6#TRMPBF uniquely combines AEC-Q100 qualification, –55°C to 150°C operation, and active-low shutdown in a 6-lead TSOT-23 - making it the only option for automotive-grade, ultra-low-drift, space-constrained current sensing or sensor signal chains.

FAQ
What is the operating temperature range of the LTC2050HVMPS6#TRMPBF?
The LTC2050HVMPS6#TRMPBF is specified and tested over –55°C to 150°C, with full electrical performance guaranteed across this range. This extended rating supports under-hood automotive applications, battery management systems, and industrial equipment exposed to extreme thermal cycling. The device meets AEC-Q100 Grade 0 requirements and is validated for reliability at these extremes.
Does the LTC2050HVMPS6#TRMPBF support dual-supply operation?
Yes, the LTC2050HVMPS6#TRMPBF operates from ±4.5V to ±5.5V dual supplies (9V to 11V total). It is not rated for single-supply use below ±4.5V - unlike the standard LTC2050 variants. This makes it ideal for precision bipolar signal paths in automotive and industrial systems using standard ±5V rails.
How does the shutdown feature work on the LTC2050HVMPS6#TRMPBF?
The LTC2050HVMPS6#TRMPBF includes an active-low shutdown pin (Pin 5). Pulling SHDN ≤ V– + 0.5V places the device in shutdown mode, reducing supply current to ≤1.3µA and placing inputs and output in high-impedance state. Releasing SHDN (to float or pull ≥ V+ – 0.5V) restores normal operation with typical startup time <10µs.
Is the LTC2050HVMPS6#TRMPBF pin-compatible with other LTC2050 variants in S6 packages?
Yes, the LTC2050HVMPS6#TRMPBF shares identical pinout and footprint with all other S6-package LTC2050 variants (e.g., LTC2050HVHS6, LTC2050HVCS6). However, its extended temperature range, AEC-Q100 qualification, and tighter offset drift spec mean it can replace those parts in demanding applications - though the reverse is not recommended for automotive or high-reliability use.
What is the maximum output current capability of the LTC2050HVMPS6#TRMPBF?
The LTC2050HVMPS6#TRMPBF is characterized to drive loads down to 2kΩ while maintaining rail-to-rail output swing. At ±5V supplies, it delivers ±4.75V minimum swing into 2kΩ, corresponding to ±2.375mA continuous output current. Peak transient currents exceed this, but sustained loading above 2kΩ is recommended for optimal DC accuracy and thermal stability.
