Product details
Overview
LT6023IMS8#PBF from Analog Devices (formerly Linear Technology) is a dual micropower precision rail-to-rail output operational amplifier in an 8-lead MSOP package. It delivers 1.4 V/µs slew rate, 30 µV max input offset voltage, 20 µA max supply current per amplifier, 40 kHz gain-bandwidth product, and operates from 3 V to 30 V supplies - ideal for low-power multiplexed ADC buffering and DAC output stages.
For engineers reviewing the LT6023IMS8#PBF datasheet, LT6023IMS8#PBF pinout, LT6023IMS8#PBF application, or LT6023IMS8#PBF equivalent, key selection criteria include its high dynamic input impedance during large input transients (±5 V), fast 0.0015% settling time (124 µs), no output phase inversion, and guaranteed performance over –40°C to +85°C in the MS8 package.
Technical Context
The LT6023IMS8#PBF employs a proprietary input stage using both NPN and PNP differential pairs to maintain high input impedance during ±5 V input steps - avoiding the current surges typical of bipolar amplifiers with back-to-back diodes. Its enhanced slew rate architecture achieves 1.4 V/µs without compromising precision specs like offset drift (±0.5 µV/°C typ) or noise (132 nV/√Hz).
This dual op-amp is optimized for MUX-buffer applications where rapid settling after channel switching is critical. It supports rail-to-rail output swing (within 115 mV of rails at 10 kΩ load) while maintaining common-mode input range from V– + 1.2 V to V+ – 1.4 V - enabling robust operation in single-supply and split-supply configurations up to ±15 V.

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 |
|---|---|---|---|
| LTC2050IMS8#PBF | Zero-drift architecture; 0.5 µV max offset, but 1.1 V/µs slew rate and 65 µA supply current | Better DC accuracy for ultra-low-drift applications; slower settling and higher power limit use in high-speed MUX buffers | Select LTC2050IMS8#PBF only when sub-1 µV offset dominates over speed and power constraints |

FAQ
What is the maximum supply voltage range supported by the LT6023IMS8#PBF?
The LT6023IMS8#PBF supports a total supply voltage range of 3 V to 30 V, including ±1.5 V to ±15 V split supplies. Absolute maximum ratings allow up to 36 V total supply, but operation beyond 30 V is not characterized or guaranteed. The LT6023IMS8#PBF maintains specified performance across its full 3 V to 30 V operating range, including PSRR >110 dB and rail-to-rail output swing.
Does the LT6023IMS8#PBF have shutdown capability?
No, the LT6023IMS8#PBF does not include shutdown functionality. Shutdown is exclusive to the LT6023-1 variants (e.g., LT6023IMS8-1#PBF), which add EN and DGND pins. The LT6023IMS8#PBF is a standard dual op-amp with continuous operation; its 20 µA per amplifier supply current is optimized for always-on micropower applications such as sensor front-ends and portable instrumentation.
What is the input common-mode voltage range for the LT6023IMS8#PBF?
The LT6023IMS8#PBF has a specified input common-mode voltage range of V– + 1.2 V to V+ – 1.4 V. This range is independent of supply voltage and holds across the full –40°C to +85°C temperature range. Exceeding this range reduces open-loop gain and increases input bias current, but the device guarantees no output phase inversion even under overdrive conditions - a key reliability feature confirmed in the LT6023IMS8#PBF datasheet.
Can the LT6023IMS8#PBF drive capacitive loads, and what is the recommended compensation?
Yes, the LT6023IMS8#PBF can drive up to 100 pF capacitive loads in unity-gain configuration. For larger loads or higher gains, a small series resistor (e.g., 10–50 Ω) between the output and load improves stability. The LT6023IMS8#PBF's internal compensation is optimized for resistive loads; adding 10 pF across the feedback resistor in high-gain configurations mitigates ringing caused by parasitic input capacitance - a technique validated in the LT6023IMS8#PBF application notes.
How does the LT6023IMS8#PBF achieve high dynamic input impedance during large input transients?
The LT6023IMS8#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 transients - maintaining >140 GΩ input resistance and eliminating transient current injection into source circuits. This feature is explicitly verified in the LT6023IMS8#PBF datasheet and is critical for clean settling in multiplexer output buffering applications.
