Product details
Overview
LT6230CS6#TRPBF from Analog Devices (formerly Linear Technology) is a single, rail-to-rail output, low-noise operational amplifier optimized for high-gain signal conditioning. It delivers 1.1nV/√Hz input voltage noise, 1450MHz gain-bandwidth product at AV ≥ 10, 3.5mA supply current, and features an enable pin for shutdown to <10µA - ideal for precision ultrasound front-ends and portable instrumentation.
For engineers reviewing the LT6230CS6#TRPBF datasheet, LT6230CS6#TRPBF pinout, LT6230CS6#TRPBF application, or LT6230CS6#TRPBF equivalent, key selection criteria include its high-speed, low-noise performance at AV ≥ 10, rail-to-rail output swing within 50mV of rails on 3.3V/5V supplies, and verified enable-controlled power gating for battery-sensitive designs.
Technical Context
The LT6230CS6#TRPBF is a unity-gain stable, voltage-feedback op amp with a proprietary architecture enabling simultaneous low noise (1.1nV/√Hz), high slew rate (250V/µs at AV = –10), and wide bandwidth (1450MHz GBW). Its internal compensation is tuned specifically for closed-loop gains ≥10, distinguishing it from the standard LT6230 (215MHz, AV ≥ 1).
It integrates a dedicated ENABLE pin that controls a high-impedance output state and reduces quiescent current to ≤10µA, with fast turn-on (300ns) and turn-off (41µs) times. The device operates from 3V to 12.6V total supply and maintains rail-to-rail output swing (≤50mV from rails) across –40°C to 85°C.
Key Specifications

| Gain-Bandwidth Product | 1450MHz at AV ≥ 10 - supports stable amplification of multi-MHz signals in active filters and ADC drivers. |
| Slew Rate | 250V/µs at AV = –10 - ensures faithful reproduction of fast transients in pulse amplification applications. |
| Supply Current | 3.5mA per amplifier - balances speed and power for portable, low-voltage systems. |
| Output Swing | Within 50mV of rails on 3.3V/5V - maximizes dynamic range in low-supply, single-ended data acquisition. |
| Shutdown Current | <10µA via ENABLE pin - extends battery life in duty-cycled instrumentation and medical sensors. |

Pinout & Package
The LT6230CS6#TRPBF is housed in a 6-lead TSOT-23 (ThinSOT™) package, 1mm height, with exposed pad thermally connected to V–. Pin 1 is OUT, Pin 2 is V–, Pin 3 is +IN, Pin 4 is –IN, Pin 5 is ENABLE, and Pin 6 is V+.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Amplifier Output | Rail-to-rail capable, drives up to 30mA; requires minimal external compensation for stability at AV ≥ 10. |
| 2 (V–) | Negative Supply Rail | Reference for all internal circuitry; exposed pad must be soldered for thermal performance (θJA = 250°C/W). |
| 3 (+IN) | Non-Inverting Input | High-impedance (6.5MΩ common-mode), low bias current (5–12µA); matched to –IN for precision DC performance. |
| 4 (–IN) | Inverting Input | Differential input node; used with feedback network to set closed-loop gain and bandwidth. |
| 5 (ENABLE) | Active-Low Enable Control | Pulled low to enable; pulled high (≥V+ – 0.35V) to disable output and reduce IS to ≤10µA. |
| 6 (V+) | Positive Supply Rail | Accepts 3V to 12.6V total supply; PSRR >90dB ensures immunity to supply ripple. |
Key Features
| Feature | Design Value |
|---|---|
| High-Gain Bandwidth Optimization | 1450MHz GBW only at AV ≥ 10 - eliminates need for external compensation in fixed-gain stages like ADC buffers. |
| Ultra-Low Noise Efficiency | en × √ISUPPLY = 1.9 - among lowest noise-power tradeoff for op amps, critical for battery-powered analog front-ends. |
| Rail-to-Rail Output Swing | Swings to within 50mV of V+ and V– on 3.3V/5V - preserves full signal headroom in low-voltage systems. |
| Fast Enable/Disable Control | 300ns turn-on / 41µs turn-off - enables precise timing control in pulsed measurement systems (e.g., time-of-flight ultrasound). |
| Robust Input Protection | Back-to-back diodes limit differential input voltage to ±0.7V - prevents latch-up when driving from high-impedance sources. |
Applications
| Ultrasound Signal Amplification | Portable Instrumentation Front-End |
|---|---|
Use Scenario: Amplifying weak, high-frequency echo signals (1–15MHz) from piezoelectric transducers in handheld ultrasound devices.

IC Role / Device Role / Timing Role: Low-output-impedance, fast-settling (55ns to 0.1%) driver with rail-to-rail output swing matching ADC reference. Use Value: 55ns 0.1% settling time and 1.1nV/√Hz noise minimize code uncertainty; 30mA output current ensures stable drive into ADC input capacitance. |
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 |
|---|---|---|---|
| LT6230CS6#TRMPBF | Same die, same specs, but marked with different date code and traceability; identical electrical and thermal performance. | No functional difference - used interchangeably in production; differs only in packaging logistics (tape/reel vs. tube). | Select based on inventory availability and procurement channel preference; no design or layout impact. |
| ADA4898-1ARMZ | Lower noise (1.0nV/√Hz), higher supply current (10.5mA), no ENABLE pin, SO-8 package; GBW = 650MHz at AV = 1. | Better noise floor but no power gating; suited for always-on, high-performance lab equipment rather than portable/battery systems. | Choose ADA4898-1ARMZ only if ultra-low noise dominates over power and enable functionality; not drop-in due to pinout and shutdown absence. |
Compared with LT6230CS6#TRPBF, LT6230CS6#TRMPBF offers identical performance with alternate traceability, while ADA4898-1ARMZ trades enable capability and power efficiency for marginally lower noise and higher static current - making the LT6230CS6#TRPBF uniquely suited for gain-stable, battery-aware high-speed analog signal chains.

FAQ
What is the gain-bandwidth product of the LT6230CS6#TRPBF, and under what conditions is it specified?
The LT6230CS6#TRPBF has a gain-bandwidth product of 1450MHz, specified at closed-loop gain ≥10 (AV ≥ 10) and TA = 25°C, VS = 5V. This distinguishes it from the standard LT6230 (215MHz, AV ≥ 1) and reflects its internal compensation optimized for higher-gain stability. The LT6230CS6#TRPBF is not rated for unity-gain stability.
Does the LT6230CS6#TRPBF support rail-to-rail input common-mode voltage?
No, the LT6230CS6#TRPBF does not support rail-to-rail input common-mode voltage. Its guaranteed input common-mode range is 1.15V to 2.65V on 3.3V supplies and 1.5V to 4V on 5V supplies - limited by CMRR specification. However, its output swings rail-to-rail (within 50mV of V+ and V–), which is explicitly supported across its full operating temperature range.
How does the ENABLE pin function on the LT6230CS6#TRPBF, and what is its logic polarity?
The ENABLE pin on the LT6230CS6#TRPBF is active-low: pulling it low (≤0.3V) enables normal operation, while pulling it high (≥V+ – 0.35V) disables the amplifier, reducing supply current to ≤10µA and placing the output in high-impedance state. Turn-on time is 300ns; turn-off time is 41µs - both measured with RL = 1kΩ and VS = 5V.
What package type and footprint does the LT6230CS6#TRPBF use, and is thermal pad connection required?
The LT6230CS6#TRPBF uses a 6-lead TSOT-23 (ThinSOT™) package, 1mm profile, with pin 1 = OUT, pin 2 = V–, pin 3 = +IN, pin 4 = –IN, pin 5 = ENABLE, pin 6 = V+. The exposed pad is electrically and thermally connected to V– and must be soldered to a PCB copper pour for thermal performance (θJA = 250°C/W). Omitting this connection risks exceeding junction temperature limits under load.
Can the LT6230CS6#TRPBF drive heavy capacitive loads, and what is the recommended isolation resistance?
The LT6230CS6#TRPBF is not unity-gain stable and exhibits increasing overshoot with capacitive loads >100pF. For loads >100pF, a series isolation resistor (RS) of 10–50Ω is recommended between the output and load capacitance. Performance graphs (G26/G27) show overshoot remains <10% with RS = 20Ω and CL = 500pF at AV = 1 or 2 - critical for driving ADC inputs or cables without instability.
