Product details
Overview
LTC2054HVIS5#TRPBF from Analog Devices (formerly Linear Technology) is a single-channel, micropower, zero-drift operational amplifier in a 5-lead TSOT-23 package, rated for operation from –40°C to +85°C. It delivers 3 μV max input offset voltage, 30 nV/°C max offset drift, 150 μA typical supply current, and rail-to-rail output swing - enabling precision DC-coupled signal conditioning in battery-powered instrumentation and low-side current sensing.
For engineers reviewing the LTC2054HVIS5#TRPBF datasheet, LTC2054HVIS5#TRPBF pinout, LTC2054HVIS5#TRPBF application, or LTC2054HVIS5#TRPBF equivalent, key selection criteria include guaranteed industrial-temperature zero-drift performance, ultra-low 1.6 μVP-P (0.01–10 Hz) noise, 500 kHz gain-bandwidth product, and compatibility with single-supply (2.7–6 V) or dual-supply (±2.5 V) configurations.
Technical Context
The LTC2054HVIS5#TRPBF employs auto-zeroing architecture with a 1 kHz internal clock to continuously correct input offset and drift, achieving near-zero DC error over temperature and common-mode voltage. Its input stage supports common-mode range from V– to V+ – 0.5 V and features 1 pA typical input bias current at 25°C.
It delivers 140 dB typical open-loop gain, 130 dB typical PSRR and CMRR, and rail-to-rail output swing into 5 kΩ loads - making it suitable for high-accuracy amplification of low-level sensor signals where long-term stability and minimal power consumption are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | 3 μV max (–40°C to +85°C); enables sub-mV DC accuracy without calibration in precision sensor front-ends. |
| Offset Drift | 30 nV/°C max (–40°C to +85°C); ensures stable DC gain over industrial temperature range. |
| Supply Current | 150 μA typical; allows continuous operation for years on coin-cell batteries in portable instrumentation. |
| Noise (0.01–10 Hz) | 1.6 μVP-P typical; supports high-resolution measurement of slow-varying DC signals like thermocouples or strain gauges. |
| Gain-Bandwidth Product | 500 kHz; sufficient for anti-alias filtering, active RC filters, and closed-loop gains up to ~100 at 5 kHz. |
| Common-Mode Input Range | V– to V+ – 0.5 V; accommodates inputs near supply rails, simplifying single-supply sensor interfacing. |
| Output Swing | Rail-to-rail into ≥100 kΩ; delivers full dynamic range when driving ADC reference buffers or low-power comparators. |
Pinout & Package
Package: 5-Lead Plastic TSOT-23 (S5), 2.9 mm × 1.6 mm × 0.9 mm, exposed pad optional, RoHS-compliant, JEDEC MO-193 compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT | Amplifier output | Delivers rail-to-rail voltage swing; requires no external pull-up/down for most precision buffer or gain stages. |
| 2 - V– | Negative supply | Reference for single-supply operation (GND) or negative rail in dual-supply systems; internally connected to exposed pad. |
| 3 - +IN | Non-inverting input | High-impedance node (1 pA bias current); accepts DC-coupled sensor outputs or reference voltages. |
| 4 - –IN | Inverting input | Used for feedback in standard op-amp configurations; sensitive to PCB leakage due to ultra-low bias current. |
| 5 - V+ | Positive supply | Accepts 2.7–6 V single supply or +2.5 V in ±2.5 V dual supply; PSRR >120 dB minimizes supply noise coupling. |
Key Features
| Feature | Design Value |
|---|---|
| Zero-drift auto-zeroing | Eliminates thermal drift-induced baseline shift in long-duration measurements (e.g., medical ECG front-ends). |
| 1.6 μVP-P 0.01–10 Hz noise | Enables 16-bit+ effective resolution in DC-coupled data acquisition without external chopper stabilization. |
| 130 dB PSRR/CMRR | Rejects supply ripple and common-mode interference in noisy industrial environments (e.g., motor drive current sensing). |
| Rail-to-rail output | Maximizes ADC utilization in single-supply systems without level-shifting circuitry or additional biasing components. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD8628ARJZ-REEL7 | Same zero-drift architecture, 1 μV max offset, but 1 mA supply current - 6.7× higher than LTC2054HVIS5#TRPBF. | Better offset spec but unsuitable for multi-year battery operation; preferred where speed (2.5 MHz GBW) outweighs power. | Select AD8628ARJZ-REEL7 only when bandwidth >500 kHz is required and power budget allows >1 mA per channel. |
| LTC2050CS5#TRPBF | Same family, lower drive strength (10 mA vs 20 mA), identical offset/drift/noise specs, but not rated for 85°C operation (only 70°C). | Valid for commercial-temperature consumer devices; lacks industrial-temp qualification for factory automation or outdoor equipment. | Choose LTC2050CS5#TRPBF only for cost-sensitive, 0°C–70°C applications where full industrial temp range is unnecessary. |
Compared with AD8628ARJZ-REEL7 and LTC2050CS5#TRPBF, the LTC2054HVIS5#TRPBF uniquely balances ultra-low drift, micropower operation, and guaranteed –40°C to +85°C performance - making it optimal for battery-powered industrial sensors and portable medical diagnostics where long-term DC stability is non-negotiable.

FAQ
What is the maximum operating temperature range for the LTC2054HVIS5#TRPBF?
The LTC2054HVIS5#TRPBF is specified for operation from –40°C to +85°C, with all key parameters-including input offset voltage (3 μV max), offset drift (30 nV/°C max), and supply current-guaranteed across this full industrial temperature range per the official Linear Technology datasheet revision.
Does the LTC2054HVIS5#TRPBF support single-supply operation?
Yes, the LTC2054HVIS5#TRPBF supports true single-supply operation from 2.7 V to 6 V. Its input common-mode range extends from V– (e.g., GND) to V+ – 0.5 V, and its rail-to-rail output can swing within 10 mV of both supply rails under light loads - enabling direct interfacing with 3.3 V or 5 V microcontrollers and ADCs without level-shifting circuitry.
What is the typical input-referred clock feedthrough of the LTC2054HVIS5#TRPBF?
The LTC2054HVIS5#TRPBF exhibits less than 0.2 μVRMS input-referred clock feedthrough at its 1 kHz auto-zeroing frequency. This residue appears as a narrow spectral peak and is independent of external resistor values - a critical specification for precision DC applications where spurious tones must be minimized below 10 Hz.
Can the LTC2054HVIS5#TRPBF drive capacitive loads directly?
The LTC2054HVIS5#TRPBF is not unity-gain stable with large capacitive loads. Driving >100 pF directly may cause peaking or oscillation. For ADC input buffering or cable driving, use a small series resistor (e.g., 10–50 Ω) between the LTC2054HVIS5#TRPBF output and the capacitor to maintain stability while preserving DC accuracy.
Is the exposed pad on the LTC2054HVIS5#TRPBF's TSOT-23 package electrically connected?
Yes, the exposed pad on the LTC2054HVIS5#TRPBF's S5 package is internally connected to V– (pin 2). It must be soldered to a PCB ground plane or negative supply copper pour to ensure proper thermal dissipation and electrical performance - especially critical for maintaining PSRR and minimizing thermal EMF errors in precision circuits.
