Product details
Overview
LTC2054HVHS5#TRPBF from Analog Devices (formerly Linear Technology) is a single-channel, high-voltage, micropower zero-drift operational amplifier in a 5-lead TSOT-23 package. It delivers 3μV max input offset voltage, 30nV/°C max drift, and rail-to-rail output swing across –40°C to 125°C, operating from ±2.7V to ±5.5V supplies. It is optimized for precision current sensing in telecom power systems.
For engineers reviewing the LTC2054HVHS5#TRPBF datasheet, LTC2054HVHS5#TRPBF pinout, LTC2054HVHS5#TRPBF application, or LTC2054HVHS5#TRPBF equivalent, key selection criteria include guaranteed high-voltage supply operation (±5.5V), ultra-low DC error over temperature, low 175μA typical supply current, and validated performance in –48V low-side current sense circuits.
Technical Context
The LTC2054HVHS5#TRPBF uses auto-zeroing architecture with a 1kHz internal clock to continuously correct input offset and drift. Its input stage supports common-mode voltage from V– to V+ – 0.9V and features 1pA typical input bias current at 25°C.
It achieves 130dB typical PSRR and CMRR, 140dB open-loop gain, and 500kHz gain-bandwidth product while maintaining 1.6μVP-P (0.01Hz–10Hz) input-referred noise - enabling stable DC-coupled amplification in high-resolution sensor interfaces without external trimming.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | ±2.7V to ±5.5V - supports bipolar high-voltage rails including –48V telecom systems with headroom for sensing resistors. |
| Input Offset Voltage (max) | ±5μV (–40°C to 125°C) - eliminates need for system-level calibration in precision instrumentation. |
| Offset Drift (max) | ±0.03μV/°C - ensures <1μV total drift over full industrial temperature range, critical for long-term stability. |
| Supply Current (typ) | 175μA - enables battery-powered or energy-constrained designs without sacrificing DC accuracy. |
| Gain-Bandwidth Product | 500kHz - sufficient for closed-loop bandwidths up to ~5kHz in unity-gain stable configurations. |
| Output Swing | Rail-to-rail (±4.78V min into 5kΩ at ±5V) - maximizes dynamic range in single-supply or split-supply signal chains. |
| PSRR / CMRR (typ) | 130dB - rejects 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. Pin 1 marked with dot; exposed pad optional for thermal enhancement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT | Amplifier output | Capable of sourcing/sinking ≥10mA; rail-to-rail swing supports full utilization of supply rails. |
| 2 - V– | Negative supply | Reference for internal circuitry; internally connected to exposed pad (if used). |
| 3 - +IN | Non-inverting input | High-impedance node (1pA typ IB); accepts signals up to V+ – 0.9V. |
| 4 - –IN | Inverting input | Matches +IN in offset and drift; used for feedback in standard op-amp configurations. |
| 5 - V+ | Positive supply | Accepts up to +5.5V; PSRR >120dB ensures immunity to supply noise. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LTC2054IS5#TRPBF | Same zero-drift architecture but rated for ±5V max supply (10V total); lower PSRR (120dB typ) and higher offset drift (±0.05μV/°C). | Not suitable for ±5.5V or –48V systems requiring full HV margin; limited to ≤±5V rails. | Select only if supply is strictly ≤±5V and cost sensitivity outweighs HV margin requirement. |
| AD8628ARTZ-R7 | Auto-zero op amp with 1μV max VOS, but 2.7V–5.5V single-supply only; no bipolar HV rating; 125μA supply current. | Requires level-shifting for bipolar sensing; not qualified for –40°C to 125°C extended range. | Use only in single-supply, lower-voltage (<6V) applications where extended temperature is not required. |
Compared with LTC2054IS5#TRPBF and AD8628ARTZ-R7, the LTC2054HVHS5#TRPBF uniquely combines ±5.5V operation, guaranteed –40°C to 125°C performance, and <5μV max offset - making it the only drop-in solution for high-reliability –48V current sensing and precision analog front-ends in extended-temperature industrial systems.

FAQ
What is the maximum supply voltage rating for the LTC2054HVHS5#TRPBF?
The LTC2054HVHS5#TRPBF is rated for a total supply voltage of 12V, supporting ±5.5V operation. This distinguishes it from standard LTC2054 variants (e.g., LTC2054IS5#TRPBF), which are limited to ±5V (10V total). Absolute maximum ratings prohibit exceeding ±5.5V on V+ and V– terminals simultaneously.
Does the LTC2054HVHS5#TRPBF support rail-to-rail input common-mode voltage?
No - the LTC2054HVHS5#TRPBF supports input common-mode voltage from V– to V+ – 0.9V, not full rail-to-rail. At ±5V supply, this allows inputs from –5V to +4.1V. The device does not phase-invert when inputs exceed this range, but performance parameters (CMRR, VOS) are only guaranteed within the specified common-mode window.
What is the typical input-referred noise of the LTC2054HVHS5#TRPBF in the 0.01Hz to 10Hz band?
The LTC2054HVHS5#TRPBF has a typical input-referred noise of 1.6μVP-P in the 0.01Hz to 10Hz band. This value is measured with RS = 100Ω and reflects the combined effect of 1/f and broadband noise, critical for DC-coupled precision measurements such as strain gauges and thermocouples.
Can the LTC2054HVHS5#TRPBF be used in single-supply configurations?
Yes - the LTC2054HVHS5#TRPBF operates from a single 2.7V to 11V supply (e.g., 11V between V+ and V–). In single-supply mode, V– is typically connected to ground, and the input common-mode range extends from 0V to V+ – 0.9V. Its rail-to-rail output ensures full dynamic range utilization.
Is the LTC2054HVHS5#TRPBF pin-compatible with other LTC2054 variants in the S5 package?
Yes - all LTC2054 variants in the 5-lead TSOT-23 (S5) package share identical pinout: Pin 1 = OUT, Pin 2 = V–, Pin 3 = +IN, Pin 4 = –IN, Pin 5 = V+. This includes LTC2054CS5#TRPBF, LTC2054IS5#TRPBF, LTC2054HS5#TRPBF, and LTC2054HVHS5#TRPBF - enabling drop-in replacement where voltage and temperature requirements align.
