Product details
Overview
LTC6226IDC#TRMPBF from Analog Devices is a single-channel, 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 guaranteed operation from –40°C to +85°C and supply range of 2.8V to 11.75V. It is widely used to drive high-resolution ADCs such as the AD7380 in precision data acquisition systems.
For engineers reviewing the LTC6226IDC#TRMPBF datasheet, LTC6226IDC#TRMPBF pinout, LTC6226IDC#TRMPBF application, or LTC6226IDC#TRMPBF equivalent, key selection criteria include ultra-low voltage noise, fast settling (58ns to 0.1%), rail-to-rail output swing, shutdown functionality, and compatibility with low-voltage (3V) and dual-supply (±5V) configurations.
Technical Context
The LTC6226IDC#TRMPBF employs a proprietary high-speed bipolar complementary architecture enabling simultaneous low noise, high slew rate, and wide bandwidth while maintaining unity-gain stability. Its input stage includes negative rail–referenced common-mode range and internal bias cancellation, supporting true single-supply operation down to 2.8V total supply.
It integrates an active shutdown control (SHDN pin) that reduces supply current to 350µA per channel while maintaining high-impedance output. The device achieves >114dB open-loop gain and >114dB CMRR across its full operating temperature range, ensuring precision performance in dynamic-range-critical signal chains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-Bandwidth Product | 420MHz - enables stable closed-loop operation up to ~330MHz at AV = +1 for high-frequency filtering or buffering. |
| Slew Rate | 180V/µs - supports clean amplification of fast transient signals without slewing distortion, e.g., 6V step in <61ns. |
| Input Voltage Noise | 1nV/√Hz @ 1MHz - preserves SNR in front-end stages driving 16-bit+ ADCs like AD7380 (91dB measured SNR). |
| Supply Range | 2.8V to 11.75V - operates from single 3V or 5V rails, or dual ±5V supplies, simplifying power architecture. |
| Output Swing | Rail-to-rail - delivers full dynamic range into high-impedance loads; VOL ≤26mV and VOH ≤26mV at no load. |
| Shutdown Current | 350µA max - reduces system power during idle cycles without external circuitry or PCB layout changes. |
| Operating Temp | –40°C to +85°C - qualified for industrial environments including automated test equipment and medical sensors. |
Pinout & Package
Package: 6-lead 2mm × 2mm plastic DFN (DC package), exposed pad connected to V–, requires soldering to PCB for thermal and electrical integrity.

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 |
|---|---|---|---|
| ADA4898-1ARMZ | Lower noise (0.9nV/√Hz), higher supply current (10.5mA), SOIC-8 only; no shutdown pin. | Preferred where ultimate noise dominates over power or board space; unsuitable for shutdown-required systems. | Select ADA4898-1ARMZ only if 3.5mA lower noise justifies 5mA higher quiescent current and loss of SHDN control. |
| LMH6629MA/NOPB | Higher slew rate (2000V/µs), wider supply range (5–12V), but higher noise (2.9nV/√Hz) and no rail-to-rail output. | Better for very high-slew applications (e.g., pulse amplification), but cannot replace LTC6226IDC#TRMPBF in single-supply, full-swing designs. | Choose LMH6629MA/NOPB only when extreme slew rate outweighs noise, output swing, and shutdown requirements. |
Compared with ADA4898-1ARMZ and LMH6629MA/NOPB, the LTC6226IDC#TRMPBF uniquely balances sub-1nV/√Hz noise, rail-to-rail output, integrated shutdown, and 2mm × 2mm DFN packaging-making it optimal for space-constrained, low-power, high-dynamic-range signal chains.

FAQ
What is the maximum supply voltage for the LTC6226IDC#TRMPBF?
The LTC6226IDC#TRMPBF has an absolute maximum total supply voltage (V+ to V–) of 12V. Its specified operating supply range is 2.8V to 11.75V, with full performance guaranteed at 3V, 5V, and ±5V supplies. Exceeding 12V risks permanent damage per Absolute Maximum Ratings.
Does the LTC6226IDC#TRMPBF support true single-supply operation?
Yes, the LTC6226IDC#TRMPBF supports true single-supply operation: its input common-mode range extends to the negative rail (V– – 0.1V), and its output swings rail-to-rail. This allows use with 3V (3V/0V) or 5V (5V/0V) supplies without level-shifting circuitry.
What is the function of Pin 3 (SHDN) on the LTC6226IDC#TRMPBF?
Pin 3 (SHDN) is an active-high shutdown control input. When driven to ≥(V+ – 1.6V), the amplifier enters low-power mode with supply current reduced to ≤520µA. When pulled to ≤(V+ – 2.75V), the device is disabled and output goes high-impedance. The LTC6226IDC#TRMPBF retains this behavior across its full –40°C to +85°C temperature range.
How does the LTC6226IDC#TRMPBF achieve 1nV/√Hz input voltage noise?
The LTC6226IDC#TRMPBF achieves 1nV/√Hz input voltage noise through a custom high-speed bipolar complementary input stage with optimized transistor sizing and biasing. This architecture minimizes thermal and flicker noise contributions while maintaining 420MHz GBW and 180V/µs slew rate-verified in production testing per Analog Devices' Rev 0 datasheet.
Is the exposed pad on the LTC6226IDC#TRMPBF's DC package electrically connected?
Yes, the exposed pad on the LTC6226IDC#TRMPBF's 6-lead 2mm × 2mm DFN (DC) package is internally connected to the V– pin and must be soldered to the PCB's ground plane. This connection is mandatory for achieving the specified thermal resistance (θJA = 80°C/W) and ensuring stable operation under load.
