Product details
Overview
LT6236HS6#TRMPBF from Analog Devices (formerly Linear Technology) is a single-channel, rail-to-rail output, low-noise operational amplifier optimized as a high-speed SAR ADC driver. It delivers 1.1nV/√Hz input voltage noise density, 215MHz gain-bandwidth product, 70V/µs slew rate, and operates across –40°C to 125°C with shutdown capability reducing supply current to ≤10µA. Its 6-lead TSOT-23 package supports space-constrained precision signal chains in industrial data acquisition systems.
For engineers reviewing the LT6236HS6#TRMPBF datasheet, LT6236HS6#TRMPBF pinout, LT6236HS6#TRMPBF application, or LT6236HS6#TRMPBF equivalent, key selection criteria include its guaranteed 18-bit settling time (570ns), ±5V/±2.5V/3.3V/5V supply flexibility, rail-to-rail output swing within 50mV of rails, and validated performance driving 16-/18-bit SAR ADCs such as the LTC2389-18 at 2.5Msps.
Technical Context
The LT6236HS6#TRMPBF employs a proprietary bipolar complementary architecture enabling simultaneous low noise (1.1nV/√Hz at 10kHz), low power (3.5mA per amplifier), and wide bandwidth (215MHz GBW). Its internal compensation ensures stability with capacitive loads up to 100pF while maintaining >45° phase margin across supply voltages from 3V to 12.6V.
It integrates an active ENABLE pin with TTL-compatible thresholds (VH = V+ – 0.15V, VL ≤ 0.3V) enabling fast turn-on (800ns) and controlled turn-off (41µs), critical for power-gated precision analog front-ends. The amplifier's differential input stage achieves 95dB CMRR and 115dB PSRR over DC–10kHz, supporting accurate signal conditioning in noisy industrial environments.

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-noise, high-speed op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADA4898-1ARMZ | Higher noise (1.0nV/√Hz), higher supply current (10.5mA), no shutdown, MSOP-8 package | Lacks integrated shutdown and TSOT-23 footprint; better suited for fixed-power, high-precision lab equipment | Select ADA4898-1ARMZ only if absolute lowest noise dominates over power and board space constraints. |
| OPA837IDBVR | Lower noise (0.95nV/√Hz), higher GBW (310MHz), no rail-to-rail output, SOT-23-6 package | Cannot swing to rails - limits dynamic range in 3.3V systems; requires level-shifting for ADC interface | Choose OPA837IDBVR only when >300MHz bandwidth is mandatory and rail-to-rail output is not required. |

FAQ
What is the maximum operating temperature range for the LT6236HS6#TRMPBF?
The LT6236HS6#TRMPBF is specified for continuous operation from –40°C to +125°C, with all electrical parameters guaranteed across this full industrial temperature range. This makes LT6236HS6#TRMPBF suitable for under-hood automotive, factory automation, and outdoor infrastructure applications where ambient temperatures exceed standard commercial grade limits.
Does the LT6236HS6#TRMPBF support single-supply operation?
Yes, the LT6236HS6#TRMPBF supports true single-supply operation from 3V to 12.6V. Its rail-to-rail output swings within 50mV of both supply rails, and its input common-mode range extends to within 1.15V of V– (0V in single-supply mode), enabling direct interfacing with 3.3V or 5V microcontroller ADCs without level-shifting circuitry.
How does the ENABLE pin function on the LT6236HS6#TRMPBF?
The ENABLE pin on the LT6236HS6#TRMPBF controls amplifier activation: pulling ENABLE ≥ V+ – 0.15V enables normal operation (3.5mA supply current), while pulling ENABLE ≤ 0.3V disables the amplifier, reducing supply current to ≤5µA. Turn-on time is 800ns and turn-off time is 41µs, allowing rapid power cycling in battery-sensitive designs.
Can the LT6236HS6#TRMPBF drive a 100Ω load while maintaining rail-to-rail output swing?
Yes, the LT6236HS6#TRMPBF can drive a 100Ω load with rail-to-rail capability: at VS = 5V, it delivers VOH ≥ 4.4V (within 600mV of V+) and VOL ≤ 60mV (within 60mV of V–) at ISOURCE/ISINK = 20mA. This ensures >4.3V output swing into 100Ω, preserving dynamic range for high-speed ADC drivers.
What is the typical settling time of the LT6236HS6#TRMPBF for 18-bit accuracy?
The LT6236HS6#TRMPBF achieves 18-bit (4ppm) settling in 570ns for a 2V output step under unity-gain configuration, as verified in the datasheet's Typical Performance Characteristics (Figure G14). This value is measured at TA = 25°C, VS = 5V, and reflects the device's optimized internal compensation for fast, monotonic settling - a critical parameter for high-throughput SAR ADC systems.
