Product details
Overview
LTC6229HMS8E#PBF 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 across –40°C to 125°C. It is used in precision ADC driver circuits such as the LTC2387-18 SAR converter.
For engineers reviewing the LTC6229HMS8E#PBF datasheet, LTC6229HMS8E#PBF pinout, LTC6229HMS8E#PBF application, or LTC6229HMS8E#PBF equivalent, key selection criteria include input voltage noise floor, harmonic distortion at 2MHz, shutdown current (500µA), rail-to-rail output swing, and MSOP-8 thermal performance (θJA = 35°C/W).
Technical Context
The LTC6229HMS8E#PBF implements a unity-gain-stable, fully differential-capable architecture with internal bias current cancellation that can be enabled/disabled via the SHDN pin to optimize noise versus input current trade-offs. Its high open-loop gain (135dB) and CMRR (110dB) support precision closed-loop configurations in wide common-mode range applications.
It features dual independent amplifiers in an 8-lead MSOP package with exposed pad (pin 9 = V–), supporting single- or split-supply operation. The SHDN pin provides independent channel disable control with defined logic thresholds (VH_SHDN = V+ – 1.6V, VL_SHDN = V+ – 2.75V) and fast turn-on/turn-off times (900ns / 500ns).

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 |
|---|---|---|---|
| ADA4898-2ARMZ | Higher 1.1nV/√Hz noise; 290MHz GBW; no shutdown; SOIC-8 only | Lacks shutdown and rail-to-rail output - unsuitable for power-gated systems or 3V single-supply designs | Choose when ultra-low distortion (<–110dBc) at lower frequencies is prioritized over noise and power management |
| LMH6629MA/NOPB | 1.05nV/√Hz noise; 720MHz GBW; 400V/μs slew; no bias cancellation; SOIC-8 | No SHDN pin or bias current control - requires external enable circuitry and higher quiescent current (18mA) | Prefer when cost-sensitive industrial designs require proven reliability but can tolerate 0.17nV/√Hz higher noise |
Compared with ADA4898-2ARMZ and LMH6629MA/NOPB, the LTC6229HMS8E#PBF uniquely combines sub-0.9nV/√Hz noise, integrated shutdown, rail-to-rail output, and bias current optimization - making it the only option qualified for 125°C operation with full spec compliance.

FAQ
What is the maximum operating junction temperature for the LTC6229HMS8E#PBF?
The LTC6229HMS8E#PBF has a maximum junction temperature (TJMAX) of 150°C, as specified in the Absolute Maximum Ratings table. This rating applies to the MSOP-8 package with exposed pad (pin 9 = V–), which must be soldered to a thermally robust PCB plane to maintain safe operation at full 125°C ambient and 16mA supply current.
Does the LTC6229HMS8E#PBF support single-supply operation?
Yes, the LTC6229HMS8E#PBF supports true single-supply operation from 2.8V to 11.75V total supply. Its input common-mode range extends to the negative rail (V– – 0.1V), and its rail-to-rail output swings within 27mV of V+ and 8mV of V– at no load - enabling direct interfacing with sensors and ADCs in 3V or 5V systems without level-shifting circuitry.
How does the SHDN pin control bias current cancellation in the LTC6229HMS8E#PBF?
The SHDN pin on the LTC6229HMS8E#PBF serves dual functions: pulling it to V+ – 2.75V disables the amplifier (ISD = 500µA), while pulling it to V+ – 0.35V enables internal bias current cancellation. This feature allows dynamic optimization - disabling cancellation improves input current matching (ΔIB ≤ 0.3µA), whereas enabling it reduces input bias current to ±0.6µA at the cost of slightly higher voltage noise.
What is the small-signal –3dB bandwidth of the LTC6229HMS8E#PBF at AV = +1?
The small-signal –3dB bandwidth of the LTC6229HMS8E#PBF is 730MHz when configured with unity gain (AV = +1) and loaded with 1kΩ to half-supply, as confirmed in the Electrical Characteristics table (Rev. B, page 4). This bandwidth remains stable across supply voltages from 3V to ±5V and temperatures from –40°C to 125°C.
Can the LTC6229HMS8E#PBF drive a 100Ω load while maintaining rail-to-rail output swing?
Yes, the LTC6229HMS8E#PBF can drive a 100Ω load with rail-to-rail capability: VOH = V+ – 180mV and VOL = V– + 85mV at ISINK = 5mA (±5V supply), and full 80mA minimum output current ensures robust drive into low-Z loads. However, output swing degrades slightly under heavy load - e.g., at ISOURCE = 25mA, VOH = V+ – 450mV - so layout and thermal management are critical for sustained 100Ω operation.
