Product details
Overview
LTC6226HDC#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 operation from 2.8V to 11.75V supplies and guaranteed performance over –40°C to 125°C. It is widely used as an ADC driver in 16-bit data acquisition systems such as the AD7380.
For engineers reviewing the LTC6226HDC#TRMPBF datasheet, LTC6226HDC#TRMPBF pinout, LTC6226HDC#TRMPBF application, or LTC6226HDC#TRMPBF equivalent, key selection criteria include ultra-low voltage noise (1nV/√Hz), high-speed settling (58ns to 0.1%), rail-to-rail output swing, shutdown functionality, and thermal robustness in automotive and industrial sensor front-ends.
Technical Context
The LTC6226HDC#TRMPBF employs a proprietary high-speed bipolar complementary process enabling simultaneous low noise, high slew rate, and wide bandwidth. Its input stage includes negative rail–referenced common-mode range and internal bias cancellation, while the output stage supports rail-to-rail swing into 1kΩ loads with <26mV saturation voltage at no load.
It integrates a dedicated SHDN pin enabling fast turn-on (2100ns) and turn-off (800ns) transitions, and maintains stability across supply voltages (3V/5V/±5V/10V) and temperatures (–40°C to 125°C), verified per AEC-Q100-relevant stress conditions.
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 (e.g., 6V step in 150ns to 0.01%) without slewing distortion. |
| Input Voltage Noise | 1nV/√Hz @ 1MHz - preserves SNR in precision analog front-ends driving high-resolution ADCs like AD7380 (91dB SNR measured). |
| Supply Range | 2.8V to 11.75V - compatible with single-supply 3.3V, 5V, and dual ±5V systems without level-shifting circuitry. |
| Operating Temp | –40°C to 125°C - qualified for under-hood automotive, industrial motor control, and harsh-environment instrumentation. |
| Input Offset Max | 95µV - ensures DC accuracy in low-gain signal chains (e.g., transimpedance amplifiers) without external trimming. |
| Shutdown Current | 450µA max - reduces system power during idle cycles while retaining fast wake-up capability (2.1µs turn-on). |
Pinout & Package
The LTC6226HDC#TRMPBF is housed in a thermally enhanced 6-lead 2mm × 2mm plastic DFN package with exposed V– pad (Pin 7) that must be soldered to PCB for optimal thermal performance (θJA = 80°C/W). The package supports high-density layout and efficient heat dissipation in space-constrained applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ | Positive Supply | Accepts 2.8V to 11.75V; powers internal bias and output stage; requires local 2.2µF decoupling. |
| V– | Negative Supply / Exposed Pad | Connects to ground or negative rail; exposed pad (Pin 7) must be soldered to PCB ground plane for thermal and electrical integrity. |
| +IN | Non-Inverting Input | High-impedance node (6MΩ common-mode RIN); supports input common-mode down to V– – 0.1V. |
| –IN | Inverting Input | Differential input pair node; matched to +IN with <140µV offset voltage match (LTC6227 dual variant). |
| OUT | Amplifier Output | Rail-to-rail capable; drives 1kΩ load to within 14mV of rails at no load; sustains ±100mA short-circuit current. |
| SHDN | Shutdown Control | Active-high logic input; asserts disable when pulled to V+ – 2.65V; draws <10µA leakage in both states. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-Low Input Voltage Noise | 1nV/√Hz enables high-fidelity amplification of microvolt-level sensor outputs without degrading system SNR. |

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), no shutdown pin, SOIC-8 only. | Better noise floor but lacks power-gating; unsuitable for battery-powered or thermally constrained layouts. | Choose ADA4898-1ARMZ when ultimate noise performance outweighs shutdown need and board area is not constrained. |
| OPA858IDBVR | Higher GBW (5.5GHz), higher input bias current (1.2µA), limited rail-to-rail output swing (1.2V headroom), 6-pin SOT-23. | Superior speed for RF/IF gain stages but incompatible with low-voltage rail-to-rail output requirements. | Choose OPA858IDBVR for GHz-range transimpedance or IF amplification where output swing margin is acceptable. |
Compared with ADA4898-1ARMZ and OPA858IDBVR, the LTC6226HDC#TRMPBF uniquely balances ultra-low noise, rail-to-rail output, integrated shutdown, and compact DFN packaging-making it optimal for space- and power-sensitive high-dynamic-range signal chains.

FAQ
What is the maximum operating temperature for the LTC6226HDC#TRMPBF?
The LTC6226HDC#TRMPBF is rated for continuous operation from –40°C to +125°C ambient temperature, with full electrical specifications guaranteed across this range. This H-grade qualification makes it suitable for under-hood automotive, industrial motor drives, and outdoor instrumentation where thermal margins are critical. The device's θJA of 80°C/W (with exposed pad soldered) ensures reliable junction temperature control even at 5.5mA supply current.
Does the LTC6226HDC#TRMPBF support single-supply operation?
Yes, the LTC6226HDC#TRMPBF fully supports true single-supply operation with input common-mode range extending to the negative rail (V– – 0.1V) and rail-to-rail output swing. When powered from 3V (3V/0V) or 5V (5V/0V), it maintains 420MHz GBW, 180V/µs slew rate, and 1nV/√Hz noise-enabling direct interfacing with ADCs and sensors without level-shifting circuitry.
What is the purpose of the exposed pad on the LTC6226HDC#TRMPBF DFN package?
The exposed pad (Pin 7) on the LTC6226HDC#TRMPBF is electrically connected to V– and serves dual thermal and electrical functions. It must be soldered to a PCB copper pour tied to the V– net to achieve the specified θJA of 80°C/W. Failure to connect it results in degraded thermal performance, potential junction overheating at full load, and possible parametric shift-especially critical in 125°C ambient applications.
How does the SHDN pin function on the LTC6226HDC#TRMPBF?
The SHDN pin on the LTC6226HDC#TRMPBF is an active-high enable input. Pulling it to V+ – 1.6V or higher enables the amplifier; pulling it to V+ – 2.65V or lower disables it, reducing supply current to ≤450µA. Turn-on time is 2100ns and turn-off time is 800ns-enabling precise power gating in burst-mode acquisition systems without compromising signal integrity.
Can the LTC6226HDC#TRMPBF drive a 100Ω load effectively?
Yes, the LTC6226HDC#TRMPBF can drive a 100Ω load with specified performance: output swing remains rail-to-rail (within 200mV of rails at 5mA sink/source), harmonic distortion stays below –93dBc at 1MHz for 4VP-P signals, and large-signal bandwidth exceeds 5.5MHz. However, output voltage compliance and thermal dissipation must be verified per application-especially at high output currents near ±100mA short-circuit limit.
