Product details
Overview
LTC2054HS5#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 125°C. It delivers 3 μV max input offset voltage, 30 nV/°C max drift, 150 μA typical supply current, and rail-to-rail output swing - enabling precision DC-coupled signal conditioning in high-temperature industrial sensor interfaces.
For engineers reviewing the LTC2054HS5#TRPBF datasheet, LTC2054HS5#TRPBF pinout, LTC2054HS5#TRPBF application, or LTC2054HS5#TRPBF equivalent, key selection criteria include guaranteed high-temp offset stability, ultra-low 1.6 μVP-P (0.01–10 Hz) noise, 500 kHz gain-bandwidth product, and compatibility with single 2.7–6 V or dual ±2.5–±5 V supplies.
Technical Context
The LTC2054HS5#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 rail-to-rail common-mode range (V– to V+ – 0.5 V) and features 1 pA typical input bias current at 25°C.
It provides 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 low-power, high-accuracy instrumentation where long-term DC stability is critical, such as thermocouple amplification or strain gauge signal chains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 6 V single supply; supports ±2.5 V to ±5 V dual supply - enables direct interfacing with Li-ion battery systems and industrial ±5 V rails. |
| Input Offset Voltage (Max) | 3 μV over –40°C to 125°C - ensures sub-mV error in 100× gain stages without calibration. |
| Offset Drift (Max) | 30 nV/°C - maintains <1 μV total drift across full operating temperature range. |
| Supply Current (Typ) | 150 μA - allows continuous operation for >10 years on a single CR2032 coin cell in low-duty-cycle sensor nodes. |
| DC to 10 Hz Noise | 1.6 μVP-P - preserves resolution in 16-bit+ data acquisition systems with slow-varying inputs. |
| Gain-Bandwidth Product | 500 kHz - supports stable closed-loop gains up to ~500 at unity-gain bandwidth, sufficient for anti-alias filtering and sensor signal conditioning. |
| Output Swing | Rail-to-rail (e.g., 2.98 V high / 3 mV low at 3 V supply, RL = 100 kΩ) - maximizes dynamic range in low-voltage systems. |
Pinout & Package
Package: 5-lead TSOT-23 (S5), 2.9 mm × 1.6 mm × 0.9 mm, exposed pad internally connected to V–.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT | Amplifier output | Capable of sourcing/sinking ≥5 mA; rail-to-rail swing enables direct ADC driving without level-shifting. |
| 2 - V– | Negative supply | Internally connected to exposed thermal pad; must be tied to ground or negative rail for thermal and electrical integrity. |
| 3 - +IN | Non-inverting input | High-impedance node (1 pA bias current); accepts signals from V– to V+ – 0.5 V. |
| 4 - –IN | Inverting input | Matches +IN performance; used for feedback configuration and differential sensing. |
| 5 - V+ | Positive supply | Accepts 2.7–6 V single or positive rail of dual supply; PSRR >120 dB minimizes supply ripple coupling. |
Key Features
| Feature | Design Value |
|---|---|
| Zero-drift auto-zeroing | Continuous offset correction at 1 kHz eliminates thermal and time-dependent drift - no manual nulling required in production. |
| Rail-to-rail output | Swings within 3 mV of rails at light loads - preserves full ADC input range in 3.3 V systems. |
| Extended temperature grade | Specified from –40°C to 125°C - qualified for under-hood automotive, downhole, and industrial control environments. |
| Low 1/f noise | 1.6 μVP-P (0.01–10 Hz) - enables stable DC measurements in electronic scales and medical front-ends. |
| High CMRR & PSRR | 130 dB typical - rejects common-mode interference and supply noise in noisy industrial settings. |
Applications
| Thermocouple Amplification | Electronic Scales |

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 architecture and pinout; rated for –40°C to 85°C (not 125°C). | Suitable for commercial/industrial equipment without extended temperature requirements. | Select when cost sensitivity outweighs need for 125°C operation; identical performance below 85°C. |
| AD8628ARJZ-R7 | Single zero-drift op amp in SOT-23-5; 6 μV max offset, 1 μV/°C drift, 1.2 mA supply current. | Higher power, higher drift - less suitable for battery-powered or high-temp precision apps. | Choose only if legacy ADI design reuse is required; inferior drift and power vs. LTC2054HS5#TRPBF. |
Compared with LTC2054IS5#TRPBF, the LTC2054HS5#TRPBF adds guaranteed 125°C operation without sacrificing offset or noise; versus AD8628ARJZ-R7, it cuts supply current by 8× and drift by 33×, enabling longer battery life and tighter thermal error budgets.

FAQ
What is the maximum operating temperature for the LTC2054HS5#TRPBF?
The LTC2054HS5#TRPBF is specified for continuous operation from –40°C to +125°C. This extended temperature grade is explicitly guaranteed per the manufacturer's ordering information table and electrical characteristics section, distinguishing it from the I-grade (–40°C to 85°C) and C-grade (0°C to 70°C) variants of the same device.
Does the LTC2054HS5#TRPBF support rail-to-rail input?
The LTC2054HS5#TRPBF does not support full rail-to-rail input. Its input common-mode voltage range extends from V– to V+ – 0.5 V. For example, with a 5 V single supply (V– = 0 V, V+ = 5 V), the valid input range is 0 V to 4.5 V. This is confirmed in the "Common Mode Input Range" specification and typical performance curves.
What is the typical supply current of the LTC2054HS5#TRPBF at 25°C?
The typical supply current of the LTC2054HS5#TRPBF is 150 μA at 25°C with no load, as stated in the Electrical Characteristics table under "Supply Current (LTC2054)" for the H-grade. Maximum supply current is 175 μA over the full –40°C to 125°C range.
Can the LTC2054HS5#TRPBF be used with a single 3.3 V supply?
Yes, the LTC2054HS5#TRPBF operates reliably with a single 3.3 V supply. Its minimum supply voltage is 2.7 V, and all key specifications - including offset, noise, and output swing - are characterized at 3 V and 5 V. At 3.3 V, the output swings to within 3 mV of the rails under light loads, supporting direct interfacing with 3.3 V ADCs.
Is the exposed pad on the LTC2054HS5#TRPBF's TSOT-23 package electrically connected?
Yes, the exposed pad on the LTC2054HS5#TRPBF's S5 (TSOT-23) package is internally connected to the V– pin (Pin 2). Per the package drawing and application notes, it must be soldered to a PCB copper area tied to the negative supply or ground to ensure proper thermal dissipation and electrical reference integrity.
