Product details
Overview
LTC6227IMS8E#PBF from Analog Devices is a dual, rail-to-rail output, unity-gain stable operational amplifier optimized for high-speed, low-noise signal conditioning. It delivers 420MHz gain-bandwidth product, 180V/µs slew rate, and 1nV/√Hz input voltage noise, with dual-channel matching (ΔVOS ≤ ±140µV) and operation from 2.8V to 11.75V supplies. It is used as an ADC driver in high-dynamic-range data acquisition systems such as the AD7380 16-bit converter.
For engineers reviewing the LTC6227IMS8E#PBF datasheet, LTC6227IMS8E#PBF pinout, LTC6227IMS8E#PBF application, or LTC6227IMS8E#PBF equivalent, key selection criteria include its ultra-low noise floor, distortion performance below –90dBC at 1MHz, shutdown functionality, MSOP-8 exposed-pad thermal package, and guaranteed operation from –40°C to 85°C.
Technical Context
The LTC6227IMS8E#PBF implements a fully differential, complementary bipolar input stage enabling rail-to-rail input common-mode range (down to V–) and rail-to-rail output swing. Its architecture supports unity-gain stability while maintaining 330MHz –3dB bandwidth at AV = +1 and >114dB open-loop gain into 1kΩ loads.
It integrates independent shutdown control per channel (SHDN pin), delivering <520µA disable current and 2.1µs turn-on time. The exposed pad (Pin 9) is internally connected to V– and must be soldered to PCB for thermal and electrical integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-Bandwidth Product | 420MHz - enables stable closed-loop operation up to ~330MHz at AV = +1 for wideband filtering or ADC buffering. |
| Slew Rate | 180V/µs - supports clean amplification of fast transient signals without slewing-induced distortion. |
| Input Voltage Noise | 1nV/√Hz @ 1MHz - preserves SNR in precision front-end stages driving high-resolution ADCs. |
| Supply Range | 2.8V to 11.75V - compatible with single-supply (3V/5V) and split-supply (±5V) systems without level-shifting. |
| Input Offset Match | ±140µV max (channel-to-channel) - ensures matched gain and phase response in dual-path signal chains. |
| Operating Temp Range | –40°C to +85°C - qualified for industrial-grade embedded instrumentation and data acquisition. |
| Shutdown Current | 450µA typical per channel - reduces system power during idle periods without compromising wake-up latency. |
Pinout & Package
Package: 8-lead MSOP with exposed pad (Pin 9 = V–). Thermal resistance θJA = 35°C/W with proper pad soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUTA) | Channel A output | Capable of rail-to-rail swing; drives 1kΩ load with <26mV headroom at 5mA sink. |
| 2 (–INA) | Channel A inverting input | Differential input node; 3pF differential capacitance minimizes high-frequency phase shift. |
| 3 (+INA) | Channel A non-inverting input | High-impedance node (6MΩ common-mode RIN) supporting precision biasing networks. |
| 4 (V–) | Negative supply / exposed pad reference | Internally tied to exposed thermal pad (Pin 9); must be soldered to PCB ground plane for thermal management. |
| 5 (V+) | Positive supply | Accepts 2.8V to 11.75V total supply; PSRR >100dB up to 100kHz. |
| 6 (OUTB) | Channel B output | Independent output with identical AC/DC specs to OUTA; supports dual-path signal processing. |
| 7 (–INB) | Channel B inverting input | Matched to –INA within ±140µV offset and ±2µA bias current for correlated dual-channel applications. |
| 8 (+INB) | Channel B non-inverting input | Enables independent configuration of second amplifier; shares same noise and CMRR characteristics as +INA. |
| 9 (Exposed Pad) | Thermal & electrical connection to V– | Not a signal pin; mandatory solder connection required to maintain junction temperature ≤150°C under load. |
Key Features

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 pin, SOIC-8 only. | Preferred where ultimate noise dominates over power or thermal constraints; unsuitable for space-constrained or power-gated designs. | Select ADA4898-2ARMZ when SNR >95dB is required and board area/power budget allow. |
| LMH6629MA/NOPB | Higher slew rate (2000V/µs), wider GBW (1.5GHz), but higher noise (1.9nV/√Hz) and no rail-to-rail output. | Better for RF/IF signal chain stages requiring extreme speed; not viable for low-voltage ADC interface due to output headroom limitations. | Choose LMH6629MA/NOPB only for >500MHz small-signal amplification where output swing is not rail-limited. |
Compared with ADA4898-2ARMZ and LMH6629MA/NOPB, the LTC6227IMS8E#PBF uniquely balances ultra-low noise, rail-to-rail output, per-channel shutdown, and MSOP-8 thermal packaging-making it optimal for space- and power-sensitive high-resolution data acquisition.

FAQ
What is the maximum operating temperature range for the LTC6227IMS8E#PBF?
The LTC6227IMS8E#PBF is specified for operation from –40°C to +85°C. This industrial temperature grade is confirmed in the ORDER INFORMATION table and Absolute Maximum Ratings section of the official datasheet. The device maintains full electrical performance-including 420MHz GBW and 1nV/√Hz noise-across this entire range when properly thermally managed via the exposed V– pad.
Does the LTC6227IMS8E#PBF support single-supply operation?
Yes, the LTC6227IMS8E#PBF supports true single-supply operation down to 2.8V total supply (e.g., 3V or 5V). Its input common-mode range extends to the negative rail (V–), and its rail-to-rail output stage swings within 20mV of both supply rails under load. These features enable direct interfacing with low-voltage microcontrollers and ADCs without level-shifting circuitry.
How is the exposed pad on the LTC6227IMS8E#PBF connected and why is it important?
The exposed pad (Pin 9) on the LTC6227IMS8E#PBF is internally connected to V– and must be soldered to a PCB copper pour tied to the negative supply or ground plane. This connection is mandatory-not optional-as it provides the primary thermal path (θJA = 35°C/W) and ensures stable operation. Failure to solder the pad risks exceeding the 150°C maximum junction temperature under normal load conditions.
What is the typical supply current per channel for the LTC6227IMS8E#PBF?
The typical supply current per channel for the LTC6227IMS8E#PBF is 5.5mA at ±5V supplies and 6.0mA at 3V single supply, as specified in the Electrical Characteristics tables. In shutdown mode, current drops to 450µA per channel, enabling significant power savings in battery-operated or duty-cycled systems without sacrificing wake-up speed (tON = 2100ns).
Can the LTC6227IMS8E#PBF drive a 100Ω load while maintaining low distortion?
Yes, the LTC6227IMS8E#PBF can drive a 100Ω load with HD2/HD3 < –77dBC at 1MHz and 4VP-P output, as verified in the Electrical Characteristics table under "Harmonic Distortion, RL = 100Ω". Its robust output stage delivers ±100mA short-circuit current and maintains <200mV saturation voltage at 5mA, ensuring linearity even under heavy loading conditions typical in video and high-speed DAC output stages.
