Product details
Overview
LTC6227HMS8E#PBF from Analog Devices is a dual, high-speed, rail-to-rail output operational amplifier optimized for driving high-resolution ADCs and precision signal chains. It delivers 420MHz gain-bandwidth product, 180V/µs slew rate, 1nV/√Hz input voltage noise, and –90dBC harmonic distortion at 1MHz with 4VP-P output into 1kΩ - enabling ultra-low-noise, wide-dynamic-range amplification in 16-bit data acquisition systems.
For engineers reviewing the LTC6227HMS8E#PBF datasheet, LTC6227HMS8E#PBF pinout, LTC6227HMS8E#PBF application, or LTC6227HMS8E#PBF equivalent, key selection criteria include its guaranteed operation from –40°C to 125°C, MSOP-8 exposed-pad package thermal performance (θJA = 35°C/W), shutdown current of 450µA max, and matched channel specifications critical for differential driver topologies.
Technical Context
The LTC6227HMS8E#PBF implements a unity-gain-stable, fully differential-capable dual op amp architecture with input common-mode range extending to the negative rail and rail-to-rail output swing. Its low 1nV/√Hz voltage noise and 2.4pA/√Hz current noise support high-fidelity transimpedance and ADC driver applications where SNR preservation is essential.
It features independent shutdown pins per channel (SHDNA/SHDNB), matched offset voltage (±140µV max), and stable operation across supply voltages from 2.8V to 11.75V - including single-supply (3V, 5V, 10V) and split-supply (±5V) configurations - with specified performance over full industrial temperature range.

Pinout & Package
Package: 8-lead MSOP with exposed pad (MSE), thermally enhanced θJA = 35°C/W; exposed pad must be soldered to PCB ground plane for optimal thermal and electrical performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUTA) | Channel A output | Low-impedance rail-to-rail output capable of sourcing/sinking ±100mA; drives ADC inputs or active filters directly. |
| 2 (–INA) | Channel A inverting input | Differential input node with 3pF differential capacitance; requires careful layout to minimize phase shift in high-frequency feedback paths. |
| 3 (+INA) | Channel A non-inverting input | High-impedance input (6MΩ common-mode resistance); referenced to V– for single-supply operation with negative rail extension. |
| 4 (V–) | Negative supply / exposed pad connection | Internally connected to exposed thermal pad; must be tied to system ground or negative rail for thermal management and noise immunity. |
| 5 (V+) | Positive supply | Accepts 2.8V to 11.75V total supply; PSRR >100dB ensures immunity to digital supply noise in mixed-signal systems. |
| 6 (OUTB) | Channel B output | Independent output with identical AC/DC specs to OUTA; enables dual-channel signal processing or complementary drive topologies. |
| 7 (–INB) | Channel B inverting input | Matched to –INA within ±140µV offset; supports precise differential gain stages and matched filter pairs. |
| 8 (SHDNA) | Channel A shutdown control | Logic-level input: VH ≥ V+ – 1.6V enables, VL ≤ V+ – 2.75V disables; reduces quiescent current to 450µA per channel. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Within 14mV of rails at no load (5V supply), enabling full utilization of ADC input range and maximizing dynamic range. |
| Ultra-low input voltage noise | 1nV/√Hz at 1MHz - 3× lower than standard high-speed op amps, critical for preserving ENOB in 16-bit+ converters. |
| Matched dual-channel performance | ±140µV max input offset match and <0.4µV/°C drift ensure stable common-mode rejection in differential receivers. |
| Wide supply voltage range | Operates from 2.8V to 11.75V - eliminates need for level-shifting in multi-rail systems and simplifies power domain partitioning. |
| Thermally optimized MSOP-8EP | θJA = 35°C/W with exposed pad - sustains 5.8mA/channel continuous operation at 125°C ambient without derating. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed, low-noise op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADA4898-2ARMZ | Lower noise (0.9nV/√Hz), higher supply current (10.5mA/ch), no shutdown function, SOIC-8 only | Better SNR in ultra-low-noise preamp stages; unsuitable for power-constrained or shutdown-required systems | Select when absolute minimum noise dominates over power and feature set; verify thermal dissipation in SOIC-8 at 125°C. |
| LMH6629MA/NOPB | Higher slew rate (2000V/µs), higher distortion (–72dBC @1MHz), no rail-to-rail output, wider supply range (±15V) | Preferred for high-voltage pulse amplification; not suitable for low-voltage ADC drivers requiring rail-to-rail swing | Choose for high-voltage, high-slew applications where output headroom is less critical than speed; avoid for precision 16-bit ADC interfaces. |
Compared with ADA4898-2ARMZ and LMH6629MA/NOPB, the LTC6227HMS8E#PBF uniquely balances ultra-low noise, rail-to-rail output, dual-channel matching, and integrated shutdown - making it the optimal choice for space-constrained, thermally demanding, high-dynamic-range ADC driver applications operating across –40°C to 125°C.

FAQ
What is the maximum operating temperature specification for the LTC6227HMS8E#PBF?
The LTC6227HMS8E#PBF is rated for continuous operation from –40°C to +125°C, with all electrical parameters fully specified across this extended industrial temperature range. This H-grade qualification distinguishes it from the I-grade (–40°C to +85°C) variants and ensures reliability in under-hood automotive, motor control, and high-ambient industrial environments. The MSOP-8EP package's low θJA of 35°C/W supports sustained operation at maximum junction temperature (150°C) under typical PCB copper pour conditions.
Does the LTC6227HMS8E#PBF support single-supply operation with input referenced to ground?
Yes, the LTC6227HMS8E#PBF supports true single-supply operation: its input common-mode range extends to the negative rail (V–), and its output swings rail-to-rail. When powered from 5V (V+ = 5V, V– = 0V), the inputs accept signals down to 0V, and the output can drive from near 0V to near 5V - enabling direct interfacing with microcontroller ADCs, digital logic, and unipolar sensors without level-shifting circuitry. This capability is confirmed in the datasheet's VCMR specification (V– – 0.1V min) and VOL/VOH test conditions.
What is the purpose of the exposed pad on the LTC6227HMS8E#PBF MSOP-8 package?
The exposed pad on the LTC6227HMS8E#PBF is internally connected to the V– supply pin and serves two critical functions: thermal dissipation and electrical grounding. With θJA = 35°C/W (vs. >100°C/W for standard MSOP), it enables reliable operation at full 5.8mA/channel supply current even at 125°C ambient. Per the datasheet, the pad must be soldered to a PCB copper area tied to the system ground or negative supply rail - failure to do so degrades thermal performance, increases junction temperature, and may cause premature device failure or parameter drift.
How does the LTC6227HMS8E#PBF achieve –90dBC harmonic distortion at 1MHz?
The LTC6227HMS8E#PBF achieves –90dBC HD2/HD3 at 1MHz through a combination of proprietary input stage design, optimized internal biasing, and rail-to-rail output architecture that minimizes crossover distortion. Its 180V/µs slew rate prevents slewing-induced harmonics, while the 1nV/√Hz voltage noise floor ensures distortion remains dominated by nonlinearities rather than noise folding. This performance is verified under standardized conditions: 4VP-P output, AV = +1, RL = 1kΩ to mid-supply, and is repeatable across the –40°C to 125°C range - making it suitable for high-fidelity 16-bit ADC driver applications like the AD7380 reference design.
Can the LTC6227HMS8E#PBF drive a 100Ω load while maintaining specified distortion performance?
Yes, the LTC6227HMS8E#PBF is characterized driving 100Ω loads: datasheet Table "Harmonic Distortion, RL = 100Ω to Half Supply" shows –77dBC HD3 at 1MHz, 4VP-P output. While this is 14dB higher than the 1kΩ load result (–91dBC), it remains sufficient for many high-speed applications. The device delivers ±100mA output current and maintains rail-to-rail swing into 100Ω (VOL = 155mV, VOH = 200mV at 5mA sink/source). For optimal distortion, use a series resistor (e.g., 33Ω) between output and 100Ω load to isolate capacitive effects and maintain stability - as demonstrated in the AD7380 driver reference circuit.
