Product details
Overview
LT6023HDD#PBF from Analog Devices (formerly Linear Technology) is a dual micropower precision rail-to-rail output operational amplifier optimized for multiplexer buffering and low-power signal conditioning. It delivers 1.4 V/µs slew rate, 30 µV max input offset voltage, 20 µA/amplifier supply current, and operates from 3 V to 30 V supplies across –40°C to 125°C. It is used in precision DAC output stages and battery-powered sensor front-ends.
For engineers reviewing the LT6023HDD#PBF datasheet, LT6023HDD#PBF pinout, LT6023HDD#PBF application, or LT6023HDD#PBF equivalent, key selection criteria include guaranteed high dynamic input impedance during ±5 V input transients, fast 0.0015% settling time (124 µs), no output phase inversion, and compatibility with 8-lead 3 mm × 3 mm DFN packaging for space-constrained industrial and automotive sensing modules.
Technical Context
The LT6023HDD#PBF employs a proprietary input stage using Zener-diode protected NPN/PNP differential pairs, enabling stable high input impedance (>140 GΩ common-mode) even during large input voltage steps up to 5 V-critical for multiplexer channel switching. Its enhanced slew rate architecture achieves 1.4 V/µs without increasing quiescent current beyond 20 µA per amplifier.
This device features rail-to-rail output swing (within 115 mV of rails at 10 kΩ load), 40 kHz gain-bandwidth product, and maintains precision over its full –40°C to 125°C operating range: input offset drift ≤ ±0.9 µV/°C (DD package), CMRR ≥ 116 dB, and PSRR ≥ 110 dB across 3 V–30 V supply range.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision micropower op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LTC2050HMS8#PBF | Zero-drift architecture; 0.5 µV max offset; 1.5 µV/°C drift; 650 µA supply current | Better DC accuracy but 32× higher power; unsuitable for battery lifetime-critical designs | Select LTC2050HMS8#PBF only when sub-µV offset dominates over power budget |
| OPA333AIDR | Zero-drift; 10 µV max offset; 0.1 µV/°C drift; 17 µA supply current; 350 kHz GBW | Lower offset and drift, but limited 5.5 V max supply and no 125°C rating | Select OPA333AIDR for commercial-temp, ultra-low-drift applications where supply <5.5 V |

FAQ
What is the maximum supply voltage rating for LT6023HDD#PBF?
The absolute maximum total supply voltage (V+ to V–) for LT6023HDD#PBF is 36 V. Operation is specified from 3 V to 30 V, with guaranteed performance including PSRR ≥ 110 dB across that full range. Exceeding 36 V risks permanent damage per Absolute Maximum Ratings.
Does LT6023HDD#PBF support true rail-to-rail input operation?
No, LT6023HDD#PBF does not feature rail-to-rail inputs. Its common-mode input range is specified from V– + 1.2 V to V+ – 1.4 V. However, its rail-to-rail output stage and high dynamic input impedance allow robust operation in inverting and noninverting configurations where inputs remain within that range-even when outputs swing fully to the rails.
How does LT6023HDD#PBF achieve high dynamic input impedance during large transients?
LT6023HDD#PBF uses a proprietary input stage with 5.5 V Zener diodes instead of conventional back-to-back junction diodes. This design prevents forward conduction during ±5 V input steps, maintaining >140 GΩ common-mode input resistance and eliminating transient current injection into upstream multiplexer or sensor circuits.
Is LT6023HDD#PBF pin-compatible with LT6023IDD#PBF?
Yes, LT6023HDD#PBF and LT6023IDD#PBF share identical 8-lead DFN (DD) package dimensions, pinout, and footprint. The only difference is temperature grade: LT6023HDD#PBF is rated for –40°C to 125°C, while LT6023IDD#PBF is rated for –40°C to 85°C. Both use the same LGRS marking and require identical PCB layout.
What is the typical settling time for a 10 V output step at 0.0015% accuracy with LT6023HDD#PBF?
The typical settling time for a 10 V output step to 0.0015% accuracy (±150 µV) with LT6023HDD#PBF is 132 µs under AVCL = 1 conditions at TA = –40°C to 125°C. This value is guaranteed by characterization and reflects the device's enhanced slew rate architecture optimized for multiplexer buffering applications.
