Product details
Overview
LT6274IS5#TRPBF from Analog Devices (formerly Linear Technology) is a single, low-power, high-speed voltage-feedback operational amplifier with current-feedback-like slew performance. It delivers 2200 V/µs slew rate, 90 MHz –3 dB bandwidth at unity gain, and ±13.25 V output swing into 1 kΩ with ±15 V supplies - enabling precision wideband large-signal amplification in data acquisition and video buffer applications.
For engineers reviewing the LT6274IS5#TRPBF datasheet, LT6274IS5#TRPBF pinout, LT6274IS5#TRPBF application, or LT6274IS5#TRPBF equivalent, key selection considerations include its C-Load™ capacitive-load stability, ±4.5 V to ±16 V dual-supply operation, 1.6 mA per-amplifier supply current, and guaranteed –40°C to 85°C performance across TSOT-23 packaging.
Technical Context
The LT6274IS5#TRPBF employs a hybrid architecture: a true voltage-feedback core with matched high-impedance inputs, augmented by dynamic current-steering that enables input-step-proportional slew rate - unlike fixed-current VFA designs. Its internal compensation adapts to capacitive loads via bootstrapped RC networks, ensuring stability without external components.
This architecture yields 40 ns settling time to 1% for a 10 V step, 10 nV/√Hz input voltage noise, and 74 dB minimum open-loop gain (RL = 1 kΩ), while maintaining unity-gain stability and full specified performance at both ±5 V and ±15 V supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Slew Rate | 2200 V/µs at AV = –1, ±15 V - enables distortion-free 10 V step response within 40 ns; input-step-dependent for optimal large-signal fidelity. |
| –3 dB Bandwidth | 90 MHz at AV = +1, ±15 V - supports high-fidelity video and RF IF amplification up to ~45 MHz small-signal signals. |
| Supply Current | 1.6 mA per amplifier at ±15 V - achieves high speed with ultra-low quiescent power, critical for portable and multi-channel systems. |
| Input Noise Voltage | 10 nV/√Hz at 1 kHz - ensures minimal signal degradation in low-level sensor and audio preamp stages. |
| Output Swing | ±13.25 V into 1 kΩ (±15 V supply) - delivers rail-to-rail usable dynamic range for ±12 V systems without clipping. |
| Capacitive Load Drive | Stable with any capacitive load (C-Load™) - eliminates need for isolation resistors when driving cables, ADC inputs, or long traces. |
| Input Offset Voltage | ±400 µV max - supports DC-coupled precision gain stages without significant baseline error in 12-bit+ data acquisition. |
Pinout & Package
LT6274IS5#TRPBF is housed in a 5-lead plastic TSOT-23 package (S5), optimized for space-constrained PCB layouts and thermal performance (θJA = 215°C/W). The package is RoHS-compliant and rated for –40°C to 85°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 OUT | Amplifier output | Capable of ±15 mA continuous output current; drives 1 kΩ to ±13.25 V or 500 Ω to ±3.5 V; stable with >10 nF capacitance. |
| 2 V– | Negative supply rail | Accepts –4.5 V to –16 V; total supply voltage (V+ – V–) must be 9 V to 32 V; forms return path for bias and output current. |
| 3 +IN | Noninverting input | High-impedance (≥100 MΩ differential), ESD-protected; supports balanced source impedances to minimize offset drift. |
| 4 –IN | Inverting input | Matched high-impedance input; accepts transient differential voltages up to ±10 V; no external clamping required. |
| 5 V+ | Positive supply rail | Accepts +4.5 V to +16 V; supplies internal bias and output stage; bypassing with 0.01–0.1 µF ceramic capacitor recommended. |
Key Features
| Feature | Design Value |
|---|---|
| Input-stage architecture | Complementary NPN/PNP emitter followers with 1 kΩ internal resistor - enables input-step-proportional slew rate and first-order bias current cancellation. |
| Capacitive-load compensation | Dynamically adjusted RC network bootstrapped during light loads; unbootstrapped under heavy capacitive loading - adds dominant-pole capacitance and phase-zero for unconditional stability. |
| DC precision | ±400 µV max input offset voltage and ±30 nA max input offset current - maintains accuracy in closed-loop configurations with gain ≥10 without trimming. |
| Wide supply range | ±4.5 V to ±16 V operation - supports legacy ±5 V, industrial ±12 V, and high-dynamic-range ±15 V systems without redesign. |
| Thermal robustness | Specified over –40°C to 85°C with TJMAX = 150°C - validated for embedded instrumentation and ATE environments with natural convection cooling. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADA4897-1ARJZ-R7 | Lower 1.0 mA supply current but 1000 V/µs slew rate and 200 MHz GBW; requires external compensation for >100 pF loads. | Better suited for battery-powered low-noise preamps than high-swing cable drivers. | Select ADA4897-1 if power budget is <1.2 mA and load capacitance is ≤100 pF; avoid for direct coax drive. |
| OPA695IDBVR | Higher 4300 V/µs slew rate and 1.7 GHz GBW, but 6.5 mA supply current and unstable with >10 pF capacitive loads. | Optimized for RF/IF gain blocks, not DC-coupled precision buffers. | Choose OPA695 only for AC-coupled >100 MHz signal chains where layout-controlled feedback and no DC offset are acceptable. |
Compared with ADA4897-1ARJZ-R7 and OPA695IDBVR, LT6274IS5#TRPBF uniquely balances ultra-high slew rate, full capacitive-load stability, and sub-2 mA power - making it the only option among the three suitable for ±12 V, DC-coupled, 75 Ω video line driving without external isolation or compensation.

FAQ
What is the maximum capacitive load the LT6274IS5#TRPBF can drive stably?
The LT6274IS5#TRPBF is rated for unconditional stability with any capacitive load - including 10 nF, coaxial cables, and ADC input capacitance - thanks to its adaptive C-Load™ compensation. Measurements confirm stable step response even with 100 nF loads, though bandwidth reduces progressively (e.g., ~3 MHz at 10 nF). No external series resistor is required for stability, though a 50 Ω series terminator is recommended for optimal pulse fidelity on 75 Ω video lines.
Does the LT6274IS5#TRPBF require external compensation components?
No, the LT6274IS5#TRPBF features fully internal frequency compensation and requires no external capacitors or resistors for stability - even in unity-gain, inverting, or noninverting configurations. Its adaptive compensation automatically adjusts for capacitive loading, eliminating design iterations related to feedback network tuning. Only standard 0.01–0.1 µF ceramic bypass capacitors on V+ and V– are recommended for supply decoupling.
Can the LT6274IS5#TRPBF operate on a single +5 V supply?
The LT6274IS5#TRPBF is specified for split-supply operation (±4.5 V to ±16 V) and is not characterized for single-supply use. Its input common-mode range extends to within 1.75 V of each rail (e.g., –3.2 V to +3.4 V at ±5 V), but output swing is asymmetric and limited near ground. For true single-supply applications, consider the LT6274's functional successor, the LTC6228, or consult Analog Devices' application notes for level-shifting workarounds - though these add complexity and degrade PSRR.
What is the thermal resistance (θJA) of the LT6274IS5#TRPBF in its TSOT-23 package?
The LT6274IS5#TRPBF has a junction-to-ambient thermal resistance (θJA) of 215°C/W in the standard 5-lead TSOT-23 package (S5), measured on a 1-inch² FR-4 board with 2 oz copper and no airflow. This value assumes minimal copper pour; adding thermal vias to an internal ground plane can reduce θJA by 30–50°C/W. At 1.6 mA supply current and ±15 V supplies, worst-case power dissipation is ~50 mW - resulting in ~11°C rise above ambient under typical conditions.
How does the slew rate of the LT6274IS5#TRPBF vary with gain configuration?
The LT6274IS5#TRPBF exhibits input-step-proportional slew rate: higher slew occurs at lower closed-loop gains due to larger differential input voltage for a given output step. For example, a 10 V output step yields ~2200 V/µs at AV = –1 (10 V input step), ~1250 V/µs at AV = –2 (5 V input step), and ~900 V/µs at AV = 1 (10 V input step). This behavior is intrinsic to its hybrid architecture and is documented in the "Slew Rate vs Input Level" curve (Figure G33) of the LT6275 datasheet.
