Product details
Overview
LT1360CS8#TRPBF from Analog Devices (formerly Linear Technology) is a single, high-speed voltage-feedback operational amplifier with 50MHz gain bandwidth, 800V/µs slew rate, and unity-gain stability. It delivers ±13V output swing into 500Ω at ±15V supplies and drives any capacitive load - making it suitable for video line drivers, active filters, and precision data acquisition front-ends.
For engineers reviewing the LT1360CS8#TRPBF datasheet, LT1360CS8#TRPBF pinout, LT1360CS8#TRPBF application, or LT1360CS8#TRPBF equivalent, key selection criteria include its C-load capability, low 9nV/√Hz input noise, 1mV max input offset voltage, ±2.5V to ±15V supply flexibility, and verified performance across –40°C to 85°C.
Technical Context
The LT1360CS8#TRPBF employs a proprietary voltage-feedback topology with current-feedback slewing behavior, enabling fast settling (60ns to 0.1%) while retaining high DC precision. Its input stage uses complementary NPN/PNP emitter followers for bias current cancellation, and internal compensation ensures stability with unlimited capacitive loading.
It features dual high-impedance inputs, gain-dependent bandwidth (50MHz at ±15V, 32MHz at ±2.5V), and robust rail-to-rail input voltage range (±13.4V at ±15V). Output stage design supports ±3.2V swing into 150Ω on ±5V supplies and delivers up to 34mA short-circuit current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth | 50MHz at ±15V - enables stable closed-loop operation up to 5MHz in G=10 configuration |
| Slew Rate | 800V/µs at ±15V - supports full-scale 10V step response in under 12.5ns without distortion |
| Input Offset Voltage | 1.0mV max at ±15V - ensures ≤0.01% gain error in precision DC-coupled signal chains |
| Input Noise Voltage | 9nV/√Hz at 10kHz - preserves SNR in low-level sensor amplification and photodiode preamps |
| Output Swing | ±13.6V into 500Ω at ±15V - drives standard video loads (75Ω terminated) with headroom for AC coupling |
| Supply Current | 5.0mA max at ±15V - balances speed and power for battery-sensitive instrumentation |
| Settling Time | 60ns to 0.1% for 10V step - meets timing requirements in 12-bit+ data acquisition systems |
| Differential Phase | 0.3° at 3.58MHz, AV=2, RL=150Ω - satisfies NTSC/PAL video fidelity standards |

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 |
|---|---|---|---|
| LT1361CS8#TRPBF | Dual-channel version; identical specs per amplifier; same S8 package; 10mA max supply current (2×) | Reduces board area in multi-channel DAQ or dual-filter designs; requires separate nulling per channel | Select when two matched high-speed amps are needed in same footprint and thermal profile |
| LT1363CS8#TRPBF | 70MHz GBW, 1000V/µs slew rate, 6.3mA supply current, 1.5mV max VOS; same S8 package | Better for >10MHz signal paths (e.g., RF IF stages); higher VOS limits DC precision use cases | Select when bandwidth/speed outweighs DC accuracy requirements and layout allows higher power dissipation |
Compared with LT1360CS8#TRPBF, LT1361CS8#TRPBF offers channel density at identical performance per channel, while LT1363CS8#TRPBF trades DC precision for higher bandwidth - both share pinout and layout compatibility but differ in thermal and nulling implementation.

FAQ
What supply voltage range does the LT1360CS8#TRPBF support?
The LT1360CS8#TRPBF operates from ±2.5V to ±15V (total supply voltage ≤36V). It is fully specified at ±2.5V, ±5V, and ±15V, with performance metrics like gain bandwidth (32MHz/37MHz/50MHz) and slew rate (450V/µs/250V/µs/800V/µs) scaling predictably across this range. Absolute maximum ratings allow transient operation up to ±18V per rail.
Is the LT1360CS8#TRPBF stable with capacitive loads?
Yes - the LT1360CS8#TRPBF is explicitly designed for unconditional stability with any capacitive load (C-Load™ trademarked feature). Its internal compensation senses the load-induced pole and adds adaptive phase margin. Datasheet curves confirm stable step response even with 10,000pF loads, though peaking increases with capacitance. No external isolation resistor is required.
What is the maximum output current capability of the LT1360CS8#TRPBF?
The LT1360CS8#TRPBF delivers up to 34mA short-circuit output current at ±15V supplies (40–54mA typical), and 29mA at ±5V. Continuous output current into resistive loads is limited by junction temperature: at ±5V/70°C ambient, max safe continuous drive into 150Ω is ~21mA. Derating is required above 70°C ambient per θJA = 130°C/W.
Can the LT1360CS8#TRPBF replace older op amps like AD817 or LM6361?
Yes - the LT1360CS8#TRPBF is documented as a direct performance upgrade for AD817, AD847, EL2020, EL2044, and LM6361 in published application notes. It improves both DC specs (lower VOS, IB) and AC performance (higher GBW, slew rate). Nulling circuitry must be removed; the LT1360CS8#TRPBF uses Pins 1 and 8 for offset trim instead of dedicated null pins.
Does the LT1360CS8#TRPBF require external compensation components?
No - the LT1360CS8#TRPBF is internally compensated and unity-gain stable without external components. Its unique topology adapts compensation dynamically for capacitive loads. External components are only needed for offset nulling (10kΩ pot between Pins 1/8 and V±) or to suppress peaking in high-CL applications using recommended RC networks per Application Note AI02.
