Product details
Overview
LT6233IS6#TRPBF from Analog Devices (formerly Linear Technology) is a single, rail-to-rail output, low-noise operational amplifier optimized for unity-gain stable operation with 60MHz gain-bandwidth product, 1.9nV/√Hz input voltage noise, and 1.2mA supply current per amplifier. It features an enable pin for shutdown (≤10µA), operates from 3V to 12.6V supplies, and delivers ±30mA output drive - ideal for precision signal conditioning in portable instrumentation and A/D driver stages.
For engineers reviewing the LT6233IS6#TRPBF datasheet, LT6233IS6#TRPBF pinout, LT6233IS6#TRPBF application, or LT6233IS6#TRPBF equivalent, this page provides verified electrical specifications, thermal performance across –40°C to 85°C, SOT-23-6 package layout guidance, and real-world design trade-offs versus higher-gain variants like LT6233-10.
Technical Context
The LT6233IS6#TRPBF employs a proprietary bipolar input stage delivering ultra-low 1.9nV/√Hz voltage noise at 10kHz while maintaining 115dB typical CMRR and 90dB PSRR over 3V–12.6V supply range. Its 17V/µs slew rate and 60MHz GBW support fast settling (175ns to 0.1%) in unity-gain configurations without phase compensation.
Integrated enable logic allows dynamic power management: disabling reduces quiescent current to ≤1.5µA (typical), with 500ns turn-on and 135µs turn-off times into 1kΩ load. Output swings within 50mV of rails under 15mA sink/source, maximizing dynamic range in low-voltage 3.3V systems.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-noise, rail-to-rail op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LT6233CS6#TRPBF | Same electrical specs but rated for 0°C to 70°C only; no extended temp qualification | Suitable for commercial-grade consumer electronics where ambient temperature stays below 70°C | Select when cost sensitivity outweighs industrial temperature requirements |
| ADA4897-1ARMZ | Lower 1.0nV/√Hz noise but higher 3.5mA supply current; no enable pin; SOIC-8 only | Better SNR in ultra-low-noise lab equipment; unsuitable for space-constrained or battery-powered designs | Choose for benchtop instruments prioritizing noise over power or size |
Compared with LT6233CS6#TRPBF, the LT6233IS6#TRPBF guarantees full specification compliance at –40°C and 85°C, making it mandatory for automotive and industrial deployments; versus ADA4897-1ARMZ, it trades 0.9nV/√Hz noise reduction for 2.3mA lower quiescent current and integrated shutdown - a decisive advantage in portable medical devices.

FAQ
What is the maximum supply voltage for LT6233IS6#TRPBF?
The absolute maximum total supply voltage (V+ to V–) for LT6233IS6#TRPBF is 12.6V. Operation beyond this rating risks permanent damage. The device is fully specified from 3V to 12.6V, with optimal noise and bandwidth performance observed at 5V and ±5V supplies per the datasheet's Electrical Characteristics tables.
Does LT6233IS6#TRPBF support rail-to-rail input common-mode range?
No, LT6233IS6#TRPBF does not support rail-to-rail input. Its guaranteed input common-mode voltage range is 1.15V to 2.65V on 3.3V supplies and 1.5V to 4V on 5V supplies - limited by CMRR specification. Input voltages outside these ranges degrade rejection and may cause output saturation.
How does the ENABLE pin function on LT6233IS6#TRPBF?
The ENABLE pin on LT6233IS6#TRPBF is active-low: pulling it ≤0.3V disables the amplifier, reducing supply current to ≤1.5µA. Driving it ≥(V+ – 0.2V) enables normal operation. Pin current is ≤–110µA when pulled low, and the device achieves full output drive within 500ns after enable assertion.
What is the typical output short-circuit current for LT6233IS6#TRPBF?
The typical continuous output short-circuit current for LT6233IS6#TRPBF is ±30mA at 5V supply and ±20mA at 3.3V supply, as specified over the –40°C to 85°C temperature range. The device includes internal protection and can sustain indefinite short-circuit conditions provided junction temperature remains below 150°C - often requiring a heatsink under worst-case conditions.
Can LT6233IS6#TRPBF drive 100Ω loads effectively?
Yes, LT6233IS6#TRPBF can drive 100Ω loads, delivering ±30mA output current. However, output swing is reduced: at 5V supply, VOH is typically 4.45V and VOL is 0.37V into 100Ω, yielding ~4.08VPP usable range. For best linearity and THD, use ≥600Ω loads; for 100Ω, verify settling time and distortion meet system requirements using Figure G30–G34 in the datasheet.
