Product details
Overview
LTC2054MPS5#TRMPBF 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 –55°C to 150°C. It delivers 3μV max input offset voltage, 30nV/°C max drift, 140dB typical open-loop gain, and rail-to-rail output swing on 2.7V to 6V supplies - enabling precision current sensing and thermocouple amplification in harsh-environment industrial systems.
For engineers reviewing the LTC2054MPS5#TRMPBF datasheet, LTC2054MPS5#TRMPBF pinout, LTC2054MPS5#TRMPBF application, or LTC2054MPS5#TRMPBF equivalent, key selection criteria include guaranteed extended-temperature performance (–55°C to 150°C), ultra-low DC error budget, micropower consumption (145–190 μA), rail-to-rail output capability, and TSOT-23 footprint compatibility with space-constrained PCB layouts.
Technical Context
The LTC2054MPS5#TRMPBF uses auto-zeroing architecture with a 1kHz internal clock to continuously correct input offset voltage and drift, achieving near-zero DC errors across temperature, supply, and common-mode voltage variations. Its input stage supports common-mode range from V– to V+ – 0.5V and features 1pA typical input bias current at 25°C.
It provides 500kHz gain-bandwidth product, 0.5V/μs slew rate, and 1.6μVP-P (0.01Hz–10Hz) input-referred noise. PSRR and CMRR are both 130dB typical, ensuring high immunity to supply and common-mode disturbances in precision analog signal chains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7V to 6V - supports single-supply battery-powered and industrial 3.3V/5V systems without dual-rail generation. |
| Input Offset Voltage (Max) | ±10μV over –55°C to 135°C - enables sub-100ppm DC accuracy in closed-loop sensor interfaces without trimming. |
| Offset Drift (Max) | ±0.1μV/°C - ensures <1μV total drift over full –55°C to 150°C operating range, critical for unattended field instrumentation. |
| Supply Current (Typ/Max) | 145μA / 190μA - allows continuous operation for years on coin-cell batteries in wireless sensor nodes. |
| Open-Loop Gain (Typ) | 140dB - provides >100,000× loop gain for stable, high-precision transimpedance and differential amplifiers. |
| Output Swing (RL = 100kΩ) | V– + 3mV to V+ – 15mV - delivers true rail-to-rail output headroom for maximum dynamic range in low-voltage systems. |
| Gain-Bandwidth Product | 500kHz - supports stable unity-gain buffering and closed-loop gains up to ~50 at 10kHz for anti-aliasing and sensor conditioning. |
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 (not electrically connected).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Amplifier Output | Delivers rail-to-rail voltage swing; drives loads ≥5kΩ directly; requires external compensation for capacitive loads >100pF. |
| 2 (V–) | Negative Supply Rail | Reference for input common-mode and output swing; internally tied to exposed pad in S5 package (optional PCB connection). |
| 3 (+IN) | Non-Inverting Input | High-impedance node (1pA bias); accepts signals from V– to V+ – 0.5V; sensitive to layout-induced leakage above 70°C. |
| 4 (–IN) | Inverting Input | High-impedance node; used for feedback and summing; matched to +IN for optimal CMRR and offset rejection. |
| 5 (V+) | Positive Supply Rail | Accepts 2.7V–6V; PSRR of 130dB minimizes supply ripple coupling into output signal path. |
Key Features
| Feature | Design Value |
|---|---|
| Extended Temperature Grade | Guaranteed operation from –55°C to 150°C - qualified for downhole oil/gas, aerospace, and engine-control applications. |
| Zero-Drift Architecture | Auto-zeroing at 1kHz eliminates long-term drift and 1/f noise - maintains DC accuracy without recalibration over decades. |
| Rail-to-Rail Output | Swings within 3mV of rails at light loads - maximizes ADC utilization and signal fidelity in 3.3V/5V data acquisition systems. |
| Ultra-Low Input Bias Current | 1pA typical at 25°C - preserves signal integrity in high-impedance sensor interfaces (e.g., pH electrodes, piezoresistive bridges). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA189IDBVR | Lower 1/f noise (0.1μVP-P), higher GBW (10MHz), but only rated to 125°C; no extended-temp qualification. | Preferred for high-speed, low-noise medical imaging; unsuitable for >125°C downhole or engine bay use. | Select OPA189IDBVR when bandwidth >1MHz is required and ambient stays ≤125°C. |
| LTC2057IMS8#PBF | Same zero-drift architecture, 150°C rating, but 8-lead MSOP package; higher drive strength (20mA vs 10mA) and lower noise (1.2μVP-P). | Better suited for driving heavier loads or multi-stage filters where board area permits larger MSOP footprint. | Choose LTC2057IMS8#PBF when output current >10mA or lower noise is critical and TSOT-23 size constraint is relaxed. |
Compared with OPA189IDBVR and LTC2057IMS8#PBF, the LTC2054MPS5#TRMPBF uniquely balances ultra-low drift, 150°C operation, and minimal 5-lead TSOT-23 footprint - making it the only option for space-constrained, high-temperature precision sensing where long-term DC stability is non-negotiable.

FAQ
What is the maximum operating temperature range guaranteed for the LTC2054MPS5#TRMPBF?
The LTC2054MPS5#TRMPBF is fully specified and guaranteed over –55°C to 150°C. This extended temperature grade (MP) is validated per MIL-STD-883 methods and includes screening for high-temperature storage, thermal cycling, and burn-in - making it suitable for downhole tools, turbine controls, and avionics where ambient exceeds 125°C.
Does the LTC2054MPS5#TRMPBF require external capacitors for stability in unity-gain buffer configuration?
No, the LTC2054MPS5#TRMPBF is unity-gain stable with capacitive loads ≤100pF. For loads >100pF (e.g., long traces or ADC input capacitance), a small series resistor (10–50Ω) between the output and load is recommended to maintain phase margin. The internal compensation eliminates need for external compensation networks in standard configurations.
How does the auto-zeroing clock feedthrough affect precision measurements with the LTC2054MPS5#TRMPBF?
The LTC2054MPS5#TRMPBF uses a 1kHz auto-zeroing clock, producing <0.2μVRMS input-referred residue at that frequency. In DC-coupled applications, this appears as a small periodic artifact; it is suppressed by adding a 100nF capacitor across the feedback resistor to limit closed-loop bandwidth below 100Hz - a standard practice in thermocouple and strain gauge circuits.
Can the LTC2054MPS5#TRMPBF be used with a single 3.3V supply for rail-to-rail output swing?
Yes - the LTC2054MPS5#TRMPBF operates from 2.7V to 6V and delivers rail-to-rail output swing. With a 3.3V supply, output swings from V– + 3mV to V+ – 15mV (typical), providing >3.25V of usable dynamic range. Input common-mode range extends from V– to V+ – 0.5V, allowing direct interfacing with 3.3V logic and sensors.
Is the exposed pad on the LTC2054MPS5#TRMPBF's TSOT-23 package electrically connected?
No - the exposed pad on the LTC2054MPS5#TRMPBF (S5 package) is not electrically connected to any internal node. It is thermally conductive and may be soldered to a PCB copper pour to improve thermal resistance (θJA reduced from 250°C/W), but must remain floating or grounded only for mechanical/thermal purposes - never tied to V+ or V–.
