Product details
Overview
LTC6229HDD#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. It is widely used to drive high-resolution SAR ADCs like the LTC2387-18 in precision data acquisition systems.
For engineers reviewing the LTC6229HDD#PBF datasheet, LTC6229HDD#PBF pinout, LTC6229HDD#PBF application, or LTC6229HDD#PBF equivalent, key selection criteria include its guaranteed operation at –40°C to 125°C, shutdown current of 500µA per channel, bias-current cancellation control, and 10-lead 3mm × 3mm DFN package with exposed V– pad for thermal performance.
Technical Context
The LTC6229HDD#PBF implements a unity-gain-stable, current-feedback-inspired architecture delivering 890MHz gain-bandwidth product and exceptional harmonic distortion performance (< –100dBc at 2MHz, 4VP-P). Its input stage includes user-selectable internal bias current cancellation to optimize noise versus input current trade-offs.
It supports single- or dual-supply operation with rail-to-rail output swing and input common-mode range extending to the negative rail. The SHDN pin enables independent channel disable with fast 900ns turn-on and 500ns turn-off timing, while maintaining low 100nA output leakage in shutdown mode.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Noise | 0.88nV/√Hz at 1MHz - enables high-SNR front-end amplification before ADC sampling |
| –3dB Bandwidth | 730MHz (AV = +1, RL = 1kΩ) - supports wideband signal conditioning up to UHF frequencies |
| Slew Rate | 500V/µs - preserves fidelity of fast transient signals such as pulse-shaped sensor outputs |
| Supply Range | 2.8V to 11.75V - compatible with 3V, 5V, and ±5V systems without level-shifting circuitry |
| Operating Temp | –40°C to 125°C - qualified for automotive under-hood and industrial harsh-environment applications |
| Shutdown Current | 500µA per channel - reduces system power by >96% during idle periods in battery-sensitive designs |
| Input Offset Drift | 0.4µV/°C - ensures stable DC accuracy across wide temperature excursions without recalibration |
Pinout & Package
Package: 10-lead 3mm × 3mm plastic DFN with exposed V– pad (Pin 11), requiring soldering to PCB ground plane for thermal and electrical integrity.
| Pin/Terminal | Circuit Role | Design Meaning |

Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Swings within 20mV of rails at 25mA load - maximizes dynamic range in low-voltage ADC driver stages |
| User-controllable bias cancellation | SHDN pin double-function: disable amplifier or toggle bias-current cancellation - optimizes noise vs. input current for specific transimpedance or precision DC use cases |
| High open-loop gain | 135dB (5.6V/µV) at RL = 1kΩ - ensures <1ppm gain error in closed-loop configurations with moderate feedback ratios |
| Low harmonic distortion | HD2/HD3 < –100dBc at 2MHz, 4VP-P - preserves SFDR in high-fidelity data converter interfaces |
| Thermally enhanced DFN | θJA = 43°C/W (with exposed pad soldered) - sustains 80mA output current at full temperature range without derating |
Applications
| Driving High-Dynamic-Range SAR ADCs | Fast Transimpedance Amplifiers |
|---|---|
|
Use Scenario: Driving the LTC2387-18 18-bit SAR ADC at 15Msps with a 7.3VP-P 1MHz input signal. IC Role / Device Role / Timing Role: Buffer and level-shift analog input while preserving SNR and SFDR before sampling. Use Value: Achieves 93.4dB SNR and 95dB SFDR in FFT analysis - directly enabled by 0.88nV/√Hz noise and < –100dBc distortion. |
Use Scenario: Converting photodiode current to voltage in optical time-of-flight (ToF) sensors. IC Role / Device Role / Timing Role: Low-noise, high-bandwidth transimpedance amplifier with adjustable bias cancellation for dark-current compensation. Use Value: Enables sub-nanosecond pulse response and <100µV offset drift over temperature - critical for picosecond-level timing resolution. |
| Active Filter Stages | High-Speed Differential-to-Single-Ended Conversion |
|
Use Scenario: Implementing 5th-order Butterworth anti-aliasing filters preceding high-speed ADCs. IC Role / Device Role / Timing Role: Unity-gain stable, low-distortion gain block in multi-pole active filter topologies. Use Value: Maintains filter shape integrity up to 730MHz - avoids phase distortion and passband ripple caused by limited GBW or poor slew rate. |
Use Scenario: Converting LVDS or differential clock/data signals to single-ended for FPGA or microcontroller inputs. IC Role / Device Role / Timing Role: Precision differential receiver with matched input impedance and rail-to-rail output swing. Use Value: Delivers <10ps channel-to-channel skew and <0.01° differential phase error - essential for jitter-sensitive digital interfaces. |
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 1.2nV/√Hz noise, no shutdown, MSOP-8 package | Lacks channel disable and thermal DFN - less suitable for power-gated or space-constrained designs | Prefer when absolute lowest distortion at DC–100kHz is prioritized over noise or power management |
| LMH6629MA/NOPB | 0.92nV/√Hz noise, 1.5GHz GBW, SOIC-8, no bias cancellation | No SHDN or bias-current control - requires external circuitry for power gating or DC offset tuning | Choose when higher bandwidth is required and board area allows SOIC packaging |
Compared with ADA4898-2ARMZ and LMH6629MA/NOPB, the LTC6229HDD#PBF uniquely integrates shutdown, bias-current cancellation, and thermally optimized DFN packaging - enabling lower system power, better noise flexibility, and higher reliability in compact, high-temperature layouts.

FAQ
What is the operating temperature range for the LTC6229HDD#PBF?
The LTC6229HDD#PBF is specified and guaranteed over –40°C to +125°C ambient temperature. This H-grade qualification makes it suitable for automotive engine control units, industrial motor drives, and outdoor instrumentation where extended thermal stability is mandatory. All key parameters-including input offset voltage, noise, and bandwidth-are tested across this full range.
Does the LTC6229HDD#PBF support single-supply operation?
Yes, the LTC6229HDD#PBF 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 both supply rails under load-enabling direct interfacing with 3.3V or 5V ADCs without level-shifting circuitry.
How does the SHDN pin function on the LTC6229HDD#PBF?
The LTC6229HDD#PBF features two independent SHDN pins (SHDNA and SHDNB) that each control one amplifier channel. Driving a SHDN pin below V+ – 2.65V disables the corresponding amplifier, reducing supply current to 500µA. The same pin also toggles internal bias current cancellation when held between V+ – 1.0V and V+ – 0.35V-providing dual functionality without extra control lines.
What is the purpose of the exposed pad on the LTC6229HDD#PBF DFN package?
The exposed pad (Pin 11) on the LTC6229HDD#PBF is electrically and thermally connected to V–. It must be soldered to a PCB copper pour tied to the system V–/ground plane. This connection achieves θJA = 43°C/W-critical for sustaining 80mA output current at 125°C ambient-and reduces thermal-induced offset drift and noise modulation.
Can the LTC6229HDD#PBF drive heavy capacitive loads without oscillation?
The LTC6229HDD#PBF is unity-gain stable but benefits from series output resistance (e.g., 10–50Ω) when driving >100pF capacitive loads. Application note DC1972 shows stable operation into 1000pF with RS = 20Ω. Its phase margin remains >45° across supply voltage (2.8V–11.75V) and temperature (–40°C–125°C), ensuring robustness in real-world PCB layouts with parasitic capacitance.
