Product details
Overview
LTC6229IMS8E#TRPBF from Analog Devices is a dual, rail-to-rail output, unity-gain stable operational amplifier optimized for ultra-low-noise, high-speed 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. It is used in precision ADC driver circuits-e.g., driving the LTC2387-18 SAR ADC-where dynamic range, low distortion, and fast settling are critical.
For engineers reviewing the LTC6229IMS8E#TRPBF datasheet, LTC6229IMS8E#TRPBF pinout, LTC6229IMS8E#TRPBF application, or LTC6229IMS8E#TRPBF equivalent, key selection criteria include input voltage noise density, harmonic distortion at 2MHz, shutdown current, rail-to-rail output swing, and MSOP-8 thermal performance with exposed V– pad.
Technical Context
The LTC6229IMS8E#TRPBF implements a proprietary high-speed bipolar-CMOS-DMOS (BCD) process architecture enabling simultaneous low noise and high slew rate. Its internal bias current cancellation circuitry is digitally controlled via the SHDN pin, allowing dynamic optimization of input current noise versus voltage noise trade-offs.
It features fully differential input stage design with common-mode range extending to the negative rail and rail-to-rail output stage capable of sourcing/sinking ≥80mA. The device maintains stability under capacitive loads up to 1000pF when series output resistance is applied, and supports single- or dual-supply operation across industrial and automotive temperature ranges.
Key Specifications

| Input Voltage Noise | 0.88nV/√Hz at 1MHz - enables high-SNR signal chains in sensor front-ends and ADC drivers |
| –3dB Bandwidth | 730MHz (AV = +1, RL = 1kΩ) - supports wideband video, RF sampling, and fast pulse amplification |
| Slew Rate | 500V/μs - ensures faithful reproduction of fast transient signals without slewing-induced distortion |
| Supply Range | 2.8V to 11.75V - compatible with 3V, 5V, and ±5V systems; no level-shifting required |
| Shutdown Current | 500μA max per channel - reduces system power during idle cycles without compromising wake-up speed |
| Output Swing | Rail-to-rail - maximizes dynamic range in low-voltage, single-supply applications |
| Harmonic Distortion | HD2/HD3 < –100dBc at 4VP-P, 2MHz - meets stringent SFDR requirements for 16+ bit ADC interfaces |
Pinout & Package
The LTC6229IMS8E#TRPBF is housed in an 8-lead MSOP package (MSE) with exposed thermal pad connected to V–. This package provides enhanced thermal dissipation (θJA = 35°C/W) and compact footprint (3mm × 3mm) for space-constrained PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUTA) | Channel A Output | Low-impedance rail-to-rail output capable of ±80mA drive into 1kΩ load |
| 2 (–INA) | Channel A Inverting Input | Differential input node with 3.5pF differential capacitance; supports DC-coupled feedback |
| 3 (+INA) | Channel A Non-Inverting Input | High-impedance input with 1.5pF common-mode capacitance; referenced to V– or VCM |
| 4 (V–) | Negative Supply / Exposed Pad | Primary ground reference and thermal path; must be soldered to PCB copper for thermal integrity |
| 5 (V+) | Positive Supply | Accepts 2.8V to 11.75V; PSRR >95dB up to 10MHz ensures supply noise rejection |

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 input bias current (±2.5μA vs. ±4.4μA disabled), lower GBW (270MHz), no shutdown pin | Best suited for fixed-gain, non-power-gated instrumentation; lacks SHDN-controlled bias cancellation | Select when lowest cost and proven reliability outweigh need for programmable noise mode and ultra-wide bandwidth |
| LMH6629MA/NOPB | Higher voltage noise (1.4nV/√Hz), higher supply current (22mA), no rail-to-rail output | Requires external level-shifting for single-supply ADC drivers; limited headroom below V– | Select only if legacy LMH6629 design reuse is mandatory and 0.88nV/√Hz noise is not required |

FAQ
What is the maximum operating temperature range for the LTC6229IMS8E#TRPBF?
The LTC6229IMS8E#TRPBF is specified for operation from –40°C to 85°C (I-grade). Its absolute maximum junction temperature is 150°C, and thermal performance is optimized via the exposed V– pad in the MSOP-8 package. For extended-range applications, the H-grade variant LTC6229HMS8E#TRPBF supports –40°C to 125°C.
How does the SHDN pin control bias current cancellation in the LTC6229IMS8E#TRPBF?
The SHDN pin on the LTC6229IMS8E#TRPBF serves dual functions: applying VH = V+ – 1.6V enables the amplifier and activates bias current cancellation (reducing IB to ±4.4μA), while VL = V+ – 2.65V disables both amplifier operation and bias cancellation (IB ≈ ±44μA). This allows real-time noise optimization based on signal amplitude and frequency.
Can the LTC6229IMS8E#TRPBF drive a 100Ω load while maintaining rail-to-rail output swing?
Yes-the LTC6229IMS8E#TRPBF delivers rail-to-rail output swing into 100Ω loads: VOH ≤ 180mV below V+ and VOL ≤ 85mV above V– at ISOURCE/ISINK = 5mA. At 25mA, swing degrades to ≤450mV (high) and ≤280mV (low), still preserving >90% of full-scale range in 5V systems.
What is the typical settling time of the LTC6229IMS8E#TRPBF for a 4V step at unity gain?
The LTC6229IMS8E#TRPBF achieves 34ns settling time to 0.1% for a 4V output step at AV = +1 into a 1kΩ load. This is enabled by its 500V/μs slew rate and 890MHz gain-bandwidth product, making it suitable for high-throughput sampling systems where aperture uncertainty must be minimized.
Does the LTC6229IMS8E#TRPBF require external compensation for unity-gain stability?
No-the LTC6229IMS8E#TRPBF is internally compensated for unity-gain stability across all supply voltages (2.8V to 11.75V) and temperatures (–40°C to 85°C). Phase margin remains ≥45° at 2.8V and improves to ≥60° at 11.75V, eliminating need for external compensation components in standard configurations.
