Product details
Overview
LT6020HDD-1#PBF from Analog Devices (formerly Linear Technology) is a dual, micropower, precision rail-to-rail output operational amplifier with shutdown control, specified for –40°C to 125°C operation in a 10-lead 3mm × 3mm DFN package. It delivers 5V/µs slew rate, 30µV max input offset voltage, 0.5µV/°C max offset drift, 100µA/amplifier supply current, and operates from 3V to 30V supplies - enabling high-accuracy signal conditioning in low-power industrial sensor front-ends and multiplexed data acquisition systems.
For engineers reviewing the LT6020HDD-1#PBF datasheet, LT6020HDD-1#PBF pinout, LT6020HDD-1#PBF application, or LT6020HDD-1#PBF equivalent, key selection considerations include its guaranteed H-grade temperature performance, EN/DGND shutdown interface compatibility with single/dual supplies, rail-to-rail output swing (≤100mV from rails at 125°C), fast 100µs enable time, and absence of output phase inversion - critical for reliable operation in battery-powered instrumentation and automotive subsystems.
Technical Context
The LT6020HDD-1#PBF integrates two independent precision op-amps with a proprietary input stage using complementary NPN/PNP differential pairs, enabling high dynamic input impedance during large input transients (up to ±5V) without diode conduction. Its enhanced slew rate architecture achieves 5V/µs at 10V step while maintaining 30µV max VOS and 0.5µV/°C max drift over –40°C to 125°C.
It features dedicated EN and DGND pins for robust shutdown control: EN threshold is referenced to DGND (0.8V low / 1.7V high), supporting logic-level interfacing across ±1.5V to ±15V supplies; shutdown reduces supply current to 1.4µA typical. The device guarantees no output phase inversion and maintains rail-to-rail output swing (≤100mV from V+ and ≤130mV from V– at 125°C) under full temperature range.

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision dual op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LT6020HMS8#PBF | 8-lead MSOP package; same electrical specs but higher θJA (163°C/W vs 43°C/W); no EN/DGND pins | Lacks shutdown functionality; unsuitable for duty-cycled systems requiring ultra-low quiescent current | Select when board space permits larger MSOP and shutdown is unnecessary |
| ADA4522-2ARZ | Zero-drift architecture; 0.005µV/°C max drift vs 0.5µV/°C; 2.5µV max VOS; 1.2mA supply current per amp | Higher precision but 12× higher power; not suitable for µA-level power budgets | Select when sub-µV drift dominates over power constraints, e.g., laboratory-grade instrumentation |
Compared with LT6020HMS8#PBF, LT6020HDD-1#PBF adds shutdown control and thermal advantage in DFN, while ADA4522-2ARZ trades 12× higher supply current for 100× lower drift - making LT6020HDD-1#PBF optimal for H-grade, low-power, shutdown-capable industrial sensing where 0.5µV/°C drift is acceptable.

FAQ
What is the maximum operating temperature range for the LT6020HDD-1#PBF?
The LT6020HDD-1#PBF is rated for continuous operation from –40°C to 125°C (H-grade), with all electrical specifications guaranteed across this full range. This includes parameters such as input offset voltage (30µV max), offset drift (0.5µV/°C max), and output swing (≤100mV from V+ at 125°C), making it suitable for under-hood automotive and industrial environments where thermal stress is critical.
Does the LT6020HDD-1#PBF support true rail-to-rail input operation?
No, the LT6020HDD-1#PBF does not feature rail-to-rail inputs. Its common-mode input range is specified as V– + 1.2V to V+ – 1.4V. However, its proprietary input stage maintains high dynamic impedance during large input transients (±5V), preventing current injection and enabling robust performance in multiplexer applications - even when driven outside its linear input range.
How does the EN pin on the LT6020HDD-1#PBF interface with microcontroller GPIOs?
The EN pin on the LT6020HDD-1#PBF is referenced to the DGND pin, not ground or supply. With DGND tied to system ground, EN requires ≥1.7V to enable and ≤0.8V to enter shutdown - compatible with 3.3V or 5V logic outputs. If DGND is tied to V– in split-supply systems, EN thresholds shift accordingly (e.g., ≥–13.3V to enable with ±15V supplies), allowing direct MCU control without level-shifting circuitry.
What is the typical enable time and output behavior during LT6020HDD-1#PBF shutdown?
The LT6020HDD-1#PBF enables in 100µs typical (120µs max) with AV = 1. During shutdown, both amplifier outputs enter high-impedance state - no current sourcing or sinking - and supply current drops to 1.4µA typical. This behavior is essential for isolating downstream circuits and minimizing power in duty-cycled sensor interfaces where rapid, controlled wake-up is required.
Can the LT6020HDD-1#PBF drive capacitive loads, and what is the recommended compensation?
Yes, the LT6020HDD-1#PBF can drive up to 100pF in unity-gain configuration. For larger capacitive loads or higher gains, adding a small series resistor (e.g., 10–50Ω) between output and load improves stability. In applications with parasitic input capacitance (e.g., >10pF at inverting node), a feedback capacitor matching the RC time constant of the resistive divider prevents peaking and oscillation - as validated in Figure 6 of the datasheet.
