Product details
Overview
LT6233IS6-10#TRMPBF from Analog Devices (formerly Linear Technology) is a single, rail-to-rail output, low-noise operational amplifier optimized for high-gain (≥10) signal conditioning. It delivers 375MHz gain-bandwidth product, 1.9nV/√Hz input voltage noise, 70V/µs slew rate, and operates from 3V to 12.6V supply rails. It is used in ultrasound amplifiers and precision A/D driver stages where high-speed, low-noise gain is required.
For engineers reviewing the LT6233IS6-10#TRMPBF datasheet, LT6233IS6-10#TRMPBF pinout, LT6233IS6-10#TRMPBF application, or LT6233IS6-10#TRMPBF equivalent, key selection criteria include its guaranteed –40°C to 85°C industrial temperature range, enable-pin shutdown (≤1.5µA disabled current), 6-lead TSOT-23 package, and performance trade-offs versus unity-gain stable variants like LT6233IS6#TRMPBF.
Technical Context
The LT6233IS6-10#TRMPBF employs a proprietary high-speed bipolar input stage enabling its 375MHz GBW at AV ≥ 10 while maintaining 1.9nV/√Hz noise density. Its internal compensation is tailored for closed-loop gains of 10 or higher, distinguishing it from the standard LT6233 (60MHz, unity-gain stable).
It integrates an active ENABLE pin that controls bias current via internal current steering, reducing quiescent supply current to ≤1.5µA in shutdown while preserving fast turn-on (≤900ns) and turn-off (≤160µs) times under ±5V operation. Output swing is rail-to-rail within 50mV at 15mA load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-Bandwidth Product | 375MHz at AV ≥ 10 - enables stable high-frequency amplification in fixed-gain instrumentation paths |
| Input Voltage Noise | 1.9nV/√Hz at 10kHz - preserves SNR in low-level sensor signal chains |
| Slew Rate | 70V/µs at AV = –10 - supports clean 2Vpp output at >2MHz full-power bandwidth |
| Supply Range | 3V to 12.6V - compatible with single-supply 3.3V/5V and split-supply ±2.5V/±5V systems |
| Operating Temperature | –40°C to 85°C - qualified for industrial and medical equipment environments |

| 4: –IN | Inverting input | Differential pair input; matched to +IN for CMRR >90dB over frequency |
| 5: ENABLE | Active-low shutdown control | Pulled low (<0.3V) to disable; pulled high (>V+–0.2V) to enable |
| 6: V+ | Positive supply | Accepts up to 12.6V total supply; powers internal bias networks and output stage |
Key Features
| Feature | Design Value |
|---|---|
| High-gain optimized architecture | 375MHz GBW only at AV ≥ 10 - eliminates need for external compensation in fixed-gain stages |
| Rail-to-rail output stage | Swings within 50mV of V+ and V– at 15mA - maintains >95% of full-scale range for 12-bit+ ADCs |
| Low-noise bipolar input | 1.9nV/√Hz + 0.78pA/√Hz unbalanced current noise - optimal for medium-impedance sources (1kΩ–10kΩ) |

IC Role / Device Role / Timing Role: Buffer and level-shifter between analog front-end and ADC sample-and-hold input. Use Value: Rail-to-rail output swing and low 1.9nV/√Hz noise maximize effective number of bits (ENOB) at full-scale input. |
| Active Filter Stage | Rail-to-Rail Instrumentation Buffer |
Use Scenario: Implementing 2nd-order high-pass or band-pass filters in low-power sensor signal conditioning. IC Role / Device Role / Timing Role: Gain-setting op amp in Sallen-Key or MFB topology with precise resistor ratio control. Use Value: Guaranteed stability at AV ≥ 10 allows use of high-Q filter designs without external compensation components. | Use Scenario: Isolating high-impedance sensor outputs (e.g., pH electrodes, strain gauges) while preserving DC accuracy. IC Role / Device Role / Timing Role: Unity-gain buffer with low VOS drift (0.5µV/°C) and high CMRR (90dB). Use Value: Though optimized for AV ≥ 10, it remains stable at AV = 1 and delivers <700µV max VOS over full temperature range. |
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 |
|---|---|---|---|
| LT6233IS6#TRMPBF | 60MHz GBW, unity-gain stable, 1.2mA supply current, same package and pinout | Preferred for AV = 1–5 applications requiring unconditional stability and lower power | Select when gain is variable or may drop below 10; not a drop-in replacement for AV ≥ 10 designs |
| ADA4898-1ARMZ | 210MHz GBW, 1.1nV/√Hz noise, 105V/µs slew, 8-lead MSOP, no enable pin | Better noise performance but lower bandwidth; requires layout change and lacks shutdown capability | Choose for ultra-low-noise, moderate-bandwidth applications where enable functionality is unnecessary |
Compared with LT6233IS6#TRMPBF, the LT6233IS6-10#TRMPBF trades unity-gain stability for 6.25× higher bandwidth at AV ≥ 10, while ADA4898-1ARMZ offers superior noise but sacrifices 43% bandwidth and disables power management - making LT6233IS6-10#TRMPBF optimal for fixed high-gain, power-aware medical signal chains.

FAQ
What is the gain-bandwidth product of the LT6233IS6-10#TRMPBF?
The LT6233IS6-10#TRMPBF has a gain-bandwidth product of 375MHz, specified for closed-loop gains of 10 or greater. This value is measured at 1MHz with AV ≥ 10 under ±5V supply conditions and reflects its optimization for high-gain, high-frequency operation - unlike the standard LT6233IS6#TRMPBF, which offers 60MHz at unity gain.
Does the LT6233IS6-10#TRMPBF support rail-to-rail output swing?
Yes, the LT6233IS6-10#TRMPBF supports rail-to-rail output swing, delivering output voltage within 50mV of either supply rail under 15mA load. This capability is verified across its full operating temperature range (–40°C to 85°C) and supply voltages from 3V to 12.6V, making it suitable for maximizing dynamic range in low-voltage ADC interface applications.
What is the function of the ENABLE pin on the LT6233IS6-10#TRMPBF?
The ENABLE pin on the LT6233IS6-10#TRMPBF is an active-low digital control input that reduces supply current to ≤1.5µA when driven below 0.3V. When pulled high to V+ – 0.2V or greater, the amplifier operates normally. This feature enables power cycling in portable or time-gated systems, with turn-on time ≤900ns and turn-off time ≤160µs under ±5V conditions.
Is the LT6233IS6-10#TRMPBF unity-gain stable?
No, the LT6233IS6-10#TRMPBF is not unity-gain stable. It is internally compensated for stable operation only at closed-loop gains of 10 or higher. For unity-gain or low-gain applications, the standard LT6233IS6#TRMPBF (60MHz, unity-gain stable) must be used instead - they share the same pinout and package but differ in compensation and bandwidth specifications.
What package type does the LT6233IS6-10#TRMPBF use?
The LT6233IS6-10#TRMPBF uses a 6-lead ThinSOT™ (TSOT-23) plastic package, measuring 2.9mm × 1.6mm × 1.0mm with a 0.95mm pitch. The exposed thermal pad is electrically and thermally connected to the V– pin, supporting efficient heat dissipation in compact layouts typical of portable medical and test equipment.
