Product details
Overview
LTC2050HVIS5#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, and 1.5µVP-P (0.01Hz–10Hz) input-referred noise, operating from 2.7V to ±5.5V supplies. It is used in high-accuracy thermocouple amplifiers and strain gauge interfaces where rail-to-rail output swing and CMRR >130dB are critical.
For engineers reviewing the LTC2050HVIS5#TRPBF datasheet, LTC2050HVIS5#TRPBF pinout, LTC2050HVIS5#TRPBF application, or LTC2050HVIS5#TRPBF equivalent, key selection criteria include guaranteed 3µV max offset voltage over temperature, –40°C to 85°C operation, 3MHz gain bandwidth, and compatibility with low-impedance loads down to 2kΩ.
Technical Context
The LTC2050HVIS5#TRPBF employs auto-zeroing architecture with a 7.5kHz internal sampling clock to continuously correct input offset and drift. Its input stage supports common-mode voltage from V– to (V+ – 1.3V), enabling single-supply operation with extended input range.
It features an enhanced rail-to-rail output stage delivering ±4.94V swing into 10kΩ on ±5V supplies, 140dB open-loop gain, and 130dB PSRR/CMRR - all maintained across its full –40°C to 85°C operating range without performance degradation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | ±3µV maximum - ensures sub-millivolt error in precision sensor front-ends without calibration. |
| Offset Drift | ±30nV/°C maximum - maintains DC accuracy over industrial temperature excursions. |
| Input Noise (0.01Hz–10Hz) | 1.5µVP-P - enables resolution of microvolt-level signals in weigh scales and medical sensors. |
| Gain Bandwidth Product | 3MHz - supports stable closed-loop gains up to ~300 at 10kHz for active filter and instrumentation amp designs. |
| Supply Range | 2.7V to ±5.5V - allows dual-supply operation for bipolar signal handling or single-supply use down to 2.7V. |
| Output Swing | ±4.94V into 10kΩ on ±5V - achieves >98% rail-to-rail utilization, minimizing headroom loss in low-voltage systems. |
| 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, thermal resistance θJA = 250°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT | Amplifier output | Capable of rail-to-rail swing into 2kΩ loads; high-current drive avoids external buffers in low-Z applications. |
| 2 - V– | Negative supply rail | Reference for internal circuitry; supports true dual-supply operation or ground-referenced single-supply configurations. |
| 3 - +IN | Non-inverting input | Low bias current (±50pA max) minimizes voltage error from source impedance in high-Z sensor interfaces. |
| 4 - –IN | Inverting input | Differential input node; matched input capacitance (1.7pF) preserves phase margin in unity-gain stable configurations. |
| 5 - V+ | Positive supply rail | Accepts up to +5.5V in dual-supply mode or up to 6V in single-supply mode; powers internal auto-zero logic. |
Key Features
| Feature | Design Value |
|---|---|
| Zero-drift architecture | Auto-zeroing at 7.5kHz eliminates long-term drift and 1/f noise - critical for DC-stable instrumentation. |
| Rail-to-rail output | Swings within 20mV of both rails into 10kΩ - maximizes dynamic range in low-voltage data acquisition systems. |
| High CMRR/PSRR | 130dB minimum - suppresses EMI and supply coupling in motor drives and factory automation I/O modules. |
| Extended temperature grade | Specified from –40°C to +85°C - qualified for industrial control cabinets and automotive under-hood auxiliary circuits. |
| Low input bias current | ±50pA maximum - enables accurate amplification of high-impedance sources like pH electrodes and piezoresistive sensors. |

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#PBF | Dual-channel version in MS8 package; same offset, drift, and noise specs; higher supply current (1.6mA/channel). | Requires two matched amplifiers (e.g., in-amp reference buffer + signal path); occupies larger PCB area. | Select when dual-channel functionality is needed and board space permits MS8 footprint. |
| LTC1150CS8#PBF | Higher voltage rating (±18V), but higher offset (±10µV), higher noise (3µVP-P), and no rail-to-rail output. | Suitable for high-voltage industrial transducers (>±10V full-scale), not for low-voltage battery-powered systems. | Select only for ±15V systems where LTC2050HVIS5#TRPBF's voltage range is insufficient. |
Compared with LTC2050HVIS5#TRPBF, LTC2051IMS8#PBF offers channel density at cost of layout area and power, while LTC1150CS8#PBF trades precision and rail-to-rail capability for high-voltage tolerance - neither is pin-compatible, and both require schematic and layout changes.

FAQ
What is the maximum input offset voltage specification for LTC2050HVIS5#TRPBF over temperature?
The LTC2050HVIS5#TRPBF has a maximum input offset voltage of ±3µV across its full specified operating temperature range of –40°C to +85°C. This value is guaranteed by design and applies to the HVI temperature grade, making it suitable for industrial environments where thermal stability is critical. The typical offset is ±0.5µV at 25°C, but system-level design must budget for the worst-case ±3µV limit.
Does LTC2050HVIS5#TRPBF support rail-to-rail input operation?
No, LTC2050HVIS5#TRPBF does not support rail-to-rail input. Its input common-mode voltage range extends from the negative supply (V–) to typically (V+ – 1.3V). For example, with ±5V supplies, the usable input range is –5V to +3.7V. This limitation is inherent to its auto-zero architecture and must be considered when designing single-supply circuits with inputs near V+.
Can LTC2050HVIS5#TRPBF drive capacitive loads directly?
LTC2050HVIS5#TRPBF is unity-gain stable but exhibits reduced phase margin with capacitive loads >100pF. Driving larger capacitive loads (e.g., ADC input capacitors or long cables) requires isolation via a series resistor (≥100Ω) or a dedicated buffer stage. The datasheet recommends limiting CL to ≤35pF for optimal transient response; exceeding this may cause overshoot or ringing in step responses.
What is the shutdown functionality of LTC2050HVIS5#TRPBF?
LTC2050HVIS5#TRPBF does not include a shutdown pin - it is the 5-lead S5 variant, which lacks the SHDN terminal present only in the 6-lead S6 and 8-lead SO-8 packages. Therefore, power management must be implemented externally, such as by disabling the supply rail or using a load switch. The part draws 0.8mA typical quiescent current and cannot be placed into low-power sleep mode internally.
Is LTC2050HVIS5#TRPBF qualified for automotive applications?
No, LTC2050HVIS5#TRPBF is not automotive-qualified. It carries the "I" suffix denoting –40°C to +85°C industrial temperature grade, but lacks the AEC-Q100 qualification and controlled manufacturing flow required for automotive use. For automotive applications, Analog Devices offers the LTC2050HVMPS6#WTRPBF (–55°C to +150°C, AEC-Q100 Grade 1), which is functionally similar but manufactured under automotive-specific process controls.
