Product details
Overview
LTC6229HMS8E#TRPBF from Analog Devices is a dual, high-speed, rail-to-rail output operational amplifier optimized for ultra-low-noise, high-dynamic-range signal conditioning. It delivers 0.88nV/√Hz input voltage noise, 730MHz –3dB bandwidth (AV = +1), 500V/µs slew rate, and operates from 2.8V to 11.75V supplies. Its key role is driving high-resolution SAR ADCs-such as the LTC2387-18-while maintaining >93dB SNR and <–93dB THD in 15Msps sampling systems.
For engineers reviewing the LTC6229HMS8E#TRPBF datasheet, LTC6229HMS8E#TRPBF pinout, LTC6229HMS8E#TRPBF application, or LTC6229HMS8E#TRPBF equivalent, this page provides verified specifications, MSOP-8 package layout, thermal-limited 125°C operation, shutdown control interface details, and validated alternatives for high-speed analog front-end design.
Technical Context
The LTC6229HMS8E#TRPBF implements a unity-gain-stable, current-feedback-enhanced voltage op amp architecture with internal bias current cancellation circuitry that can be enabled/disabled via the SHDN pin to optimize noise performance. Its input stage includes negative-rail-compatible common-mode range (V– – 0.1V) and rail-to-rail output swing (within 20mV of rails at 25mA).
It features dual-channel integration in an 8-lead MSOP package with exposed pad (pin 9 = V–), supporting independent shutdown per channel and configurable input bias cancellation. The device maintains 890MHz gain-bandwidth product and >135dB open-loop gain (RL = 1kΩ) across its –40°C to 125°C operating temperature range.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADA4898-2ARMZ | Higher 1.05nV/√Hz noise, lower 290MHz GBW, no shutdown, ±3V to ±12V supply only | Best suited for fixed-supply, non-power-gated instrumentation where ultimate noise isn't critical | Select when board space allows SOIC-8 and shutdown functionality is unnecessary |

FAQ
What is the maximum operating junction temperature for LTC6229HMS8E#TRPBF?
The LTC6229HMS8E#TRPBF has a maximum junction temperature (TJMAX) of 150°C, with thermal resistance θJA = 35°C/W when the exposed pad (pin 9) is properly soldered to a PCB ground plane. This allows reliable operation at 125°C ambient temperature under typical 16mA/channel load conditions, as confirmed in the Absolute Maximum Ratings table.
Does LTC6229HMS8E#TRPBF support single-supply operation?
Yes, the LTC6229HMS8E#TRPBF supports true single-supply operation from 2.8V to 11.75V. Its input common-mode range extends to the negative rail (V– – 0.1V), and its rail-to-rail output swings within 20mV of V– and 60mV of V+ at 25mA load-enabling full-scale signal handling in 3V or 5V systems without level-shifting circuitry.
How does the SHDN pin control bias current cancellation in LTC6229HMS8E#TRPBF?
In the LTC6229HMS8E#TRPBF, the SHDN pin serves dual functions: applying VIL ≤ V+ – 2.65V disables the amplifier and sets bias cancellation to disabled state, while VIH ≥ V+ – 1.6V enables the amplifier and activates bias cancellation. Intermediate voltages (e.g., V+ – 1.0V) disable bias cancellation while keeping the amplifier active-allowing trade-off between input current noise (3pA/√Hz vs. 6.3pA/√Hz) and offset voltage.
What is the harmonic distortion performance of LTC6229HMS8E#TRPBF at 1MHz?
At 1MHz with 4VP-P output into 1kΩ, the LTC6229HMS8E#TRPBF achieves HD2/HD3 of –107dBc/–114dBc. With 2VP-P output, distortion improves to –119dBc/–132dBc. These values are measured under specified conditions (AV = +1, VS = ±5V) and confirm suitability for high-fidelity signal paths such as audio preamps and medical sensor interfaces.
Is LTC6229HMS8E#TRPBF pin-compatible with other members of the LTC6228/LTC6229 family?
No-LTC6229HMS8E#TRPBF uses an 8-lead MSOP package (MSE), while LTC6229HDD#TRPBF uses a 10-lead 3mm × 3mm DFN and LTC6229HDC#TRPBF uses a 6-lead 2mm × 2mm DFN. Pinouts differ across packages; the MSOP variant has dedicated SHDNA and SHDNB pins, whereas DFN variants integrate shutdown control differently. Always verify pin mapping using the specific package's pin configuration diagram.
