Product details
Overview
LTC6254HMS#PBF from Analog Devices (formerly Linear Technology) is a quad rail-to-rail input/output operational amplifier optimized for high-speed, low-power signal conditioning in precision analog systems. It delivers 720MHz gain-bandwidth product, 280V/µs slew rate, and 2.75nV/√Hz input voltage noise at just 3.5mA per amplifier, operating from 2.5V to 5.25V supplies across –40°C to 125°C. It is used as a high-fidelity ADC driver in 16-bit data acquisition systems.
For engineers reviewing the LTC6254HMS#PBF datasheet, LTC6254HMS#PBF pinout, LTC6254HMS#PBF application, or LTC6254HMS#PBF equivalent, key selection criteria include guaranteed 125°C operation, quad-channel matching performance, shutdown current of 42µA, and MSOP-16 package compatibility with space-constrained industrial sensor front-ends and battery-powered instrumentation.
Technical Context
The LTC6254HMS#PBF employs a dual-input-stage architecture-PNP-based for VCM = V– to V+ – 1.2V and NPN-based for VCM = V+ – 1.2V to V+-enabling true rail-to-rail common-mode range. Input offset voltage is trimmed to ≤350µV (PNP mode) and ≤2.2mV (NPN mode) at 5V supply.
Each amplifier features independent unity-gain stability, 400MHz –3dB bandwidth at AV = 1, and fast 3.5µs turn-on time from shutdown. Output drives ±90mA while maintaining rail-to-rail swing (≤120mV from rails at 25mA load), supporting direct interface to SAR ADC reference buffers and active filter stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-Bandwidth Product | 720MHz - enables stable closed-loop operation up to ~350MHz at AV = 2 without external compensation |
| Slew Rate | 280V/µs - supports clean 4V step response in <36ns, critical for driving fast 16-bit ADCs like LTC2393-16 |
| Input Voltage Noise | 2.75nV/√Hz @ 1MHz - preserves SNR in wideband sensor signal chains and RF IF amplifiers |
| Supply Current per Amp | 3.5mA max @ 5V - allows four channels to operate within 14mA total, suitable for thermally constrained modules |
| Operating Temp Range | –40°C to 125°C - qualified for under-hood automotive, industrial PLC, and aerospace avionics environments |
| Input Common Mode Range | V– to V+ - eliminates level-shifting need when interfacing with single-supply sensors or DACs |
| Output Swing | Rail-to-rail - delivers full dynamic range into 1kΩ loads, minimizing headroom loss in low-voltage systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad rail-to-rail op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADA4891-4ARUZ | Lower GBW (220MHz), higher supply current (5.5mA/amp), no shutdown pin | Not suitable for >10MHz closed-loop designs or ultra-low-power battery operation | Select when cost sensitivity outweighs speed/power requirements and shutdown is unnecessary |
| OPA4350UA | Lower slew rate (38V/µs), higher noise (7nV/√Hz), wider supply range (2.7–5.5V) | Cannot drive 16-bit ADCs at >100ksps without degradation; better for general-purpose low-noise DC apps | Select when DC precision dominates over AC performance and extended voltage margin is needed |
Compared with ADA4891-4ARUZ and OPA4350UA, the LTC6254HMS#PBF uniquely combines 720MHz GBW, 280V/µs slew rate, and 42µA shutdown in a quad configuration-making it the only option capable of maintaining 16-bit fidelity at multi-MHz sample rates while meeting stringent thermal and power budgets in harsh-environment systems.

FAQ
What is the maximum operating junction temperature for LTC6254HMS#PBF?
The LTC6254HMS#PBF has a maximum junction temperature of 150°C, with thermal resistance θJA = 125°C/W (measured on standard PCB with minimal copper). Its specified operating temperature range is –40°C to 125°C ambient, making it suitable for under-hood automotive and industrial control cabinet deployments where ambient temperatures exceed 105°C.
Does LTC6254HMS#PBF support true rail-to-rail input common-mode range?
Yes, the LTC6254HMS#PBF supports input common-mode voltage from V– to V+, verified across its full –40°C to 125°C operating range. This is achieved via dual PNP/NPN input stages that switch seamlessly at ~1.2V below V+, eliminating input range gaps and ensuring consistent offset behavior across the entire supply rail.
Can LTC6254HMS#PBF drive a 100Ω load while maintaining rail-to-rail output swing?
No-the LTC6254HMS#PBF guarantees rail-to-rail output swing only for loads ≥1kΩ. At 100Ω, output swing degrades to within ~270mV of each rail (VOH/VOL) at 25mA source/sink. For 100Ω loads, use external series resistance or consider a dedicated line driver; the LTC6254HMS#PBF is optimized for high-Z ADC inputs and filter stages.
Is shutdown functionality available on all four amplifiers in LTC6254HMS#PBF?
No-LTC6254HMS#PBF does not include individual shutdown pins per amplifier. Unlike the dual LTC6253HMS8#PBF (which offers SHDNA/SHDNB), the quad LTC6254HMS#PBF lacks dedicated shutdown control. Shutdown capability is only available on the single LTC6252 and dual LTC6253 variants in MS10 and TSOT-23 packages.
What is the typical input offset voltage drift over temperature for LTC6254HMS#PBF?
The LTC6254HMS#PBF has a typical input offset voltage drift of 2.75µV/°C (max ±3.5µV/°C), measured across –40°C to 125°C. This low drift-combined with initial offset ≤350µV-ensures <±0.5mV total offset variation over full temperature range, critical for precision DC-coupled sensor interfaces and medical front-ends.
