Product details
Overview
LT6023HMS8#PBF from Analog Devices (formerly Linear Technology) is a dual micropower precision rail-to-rail output operational amplifier in an 8-lead MSOP package, rated for –40°C to 125°C operation. 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 rail-to-rail output swing - enabling high-accuracy signal conditioning in low-power multiplexed ADC front-ends.
For engineers reviewing the LT6023HMS8#PBF datasheet, LT6023HMS8#PBF pinout, LT6023HMS8#PBF application, or LT6023HMS8#PBF equivalent, key selection considerations include its enhanced slew rate at micropower levels, ±13.6 V input range capability in MUX buffer configurations, high dynamic input impedance during large input transients, and guaranteed performance across automotive-grade temperature extremes.
Technical Context
The LT6023HMS8#PBF employs a proprietary input stage with Zener-based protection that maintains high input impedance during ±5 V input steps - critical for multiplexer channel switching without transient loading. Its architecture avoids phase inversion and supports fast settling (124 µs to 0.0015% for 5 V step), even under wide supply ranges (3 V to 30 V).
Unlike conventional micropower op-amps, it achieves 1.4 V/µs slew rate without sacrificing precision: input offset drift is ±0.5 µV/°C (MS8 package), CMRR is 116 dB minimum, and PSRR is 110 dB minimum over temperature - making it suitable for precision DC-coupled sensor interfaces and DAC output buffering where stability and accuracy coexist with speed.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Slew Rate | 1.4 V/µs (typical, 10 V step); enables fast settling in multiplexed data acquisition without sacrificing micropower operation |
| Input Offset Voltage | 30 µV max (MS8 package, H-grade); ensures <1 LSB error in 16-bit systems with ≤10 kΩ source impedance |
| Supply Current | 20 µA per amplifier max (–40°C to 125°C); supports battery-powered wireless sensor nodes with multi-year runtime |
| Gain-Bandwidth Product | 40 kHz (min); sufficient for anti-aliasing and post-DAC filtering up to ~10 kHz closed-loop bandwidth |
| Rail-to-Rail Output | VOL = 380 mV, VOH = 190 mV (RL = 10 kΩ, –40°C to 125°C); delivers >97% of full-scale swing with 3 V supply |
| Input Common Mode Range | V– + 1.2 V to V+ – 1.4 V; allows use in inverting and noninverting configurations with inputs outside rails (e.g., ±13.5 V swing on ±15 V supplies) |
| Operating Temperature | –40°C to 125°C (H-grade); qualified for under-hood automotive and industrial control applications |
Pinout & Package
LT6023HMS8#PBF uses the 8-lead plastic MSOP (MS8) package with exposed pad connected to V–. Thermal resistance θJA = 163°C/W; θJC = 40°C/W. Pin 1 is marked with dot; pin numbering follows standard MSOP top-view convention.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUTA) | Amplifier A output | Drives external load; rail-to-rail swing; high-impedance when unused (no internal termination) |
| 2 (–INA) | Inverting input of Amp A | Differential node; protected by Zener diodes; maintains high impedance during ±5 V transients |
| 3 (+INA) | Noninverting input of Amp A | Differential node; same protection and impedance behavior as –INA |
| 4 (V–) | Negative power supply | Reference for both amplifiers and exposed thermal pad; requires local bypass capacitor |
| 5 (V+) | Positive power supply | Reference for both amplifiers; requires local bypass capacitor; supports 3 V to 30 V total supply |
| 6 (OUTB) | Amplifier B output | Independent output; identical specs to OUTA; no crosstalk limitation cited in datasheet |
| 7 (–INB) | Inverting input of Amp B | Functionally identical to –INA; fully isolated from Amp A inputs |
| 8 (+INB) | Noninverting input of Amp B | Functionally identical to +INA; independent bias current path |
Key Features
| Feature | Design Value |
|---|---|
| Enhanced slew rate at micropower | 1.4 V/µs at only 20 µA per amplifier - eliminates trade-off between speed and quiescent current in portable systems |
| High dynamic input impedance | Zener-protected inputs maintain >140 GΩ common-mode resistance during 5 V input steps - prevents MUX-induced settling errors |
| No output phase inversion | Guaranteed monotonic output response beyond input common-mode limits - essential for comparator-like monitoring circuits |
| Wide supply range support | Operates from 3 V to 30 V total supply - compatible with single-cell Li-ion (3.0–4.2 V), dual ±15 V industrial, and 24 V automotive rails |
| Automotive-grade temperature range | Specified from –40°C to 125°C ambient - meets AEC-Q100 stress test requirements for under-dash electronics |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual precision rail-to-rail output amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADA4522-2ARMZ | Zero-drift architecture; 0.3 µV max offset; 2.7 V to 36 V supply; 2.7 MHz GBW; higher quiescent current (750 µA/amplifier) | Better DC accuracy but 37× higher supply current; unsuitable for micropower battery operation | Select ADA4522-2ARMZ only when sub-microvolt offset and near-zero drift dominate over power budget. |
| OPA2333AIDR | Zero-drift; 10 µV max offset; 1.8 V to 5.5 V supply; 350 kHz GBW; 17 µA/amplifier; –40°C to 125°C | Narrower supply range; lower slew rate (0.16 V/µs); optimized for ultra-low-voltage systems, not wide-supply industrial use | Choose OPA2333AIDR for single-supply ≤5.5 V designs where micropower and zero-drift outweigh wide-voltage flexibility. |
Compared with ADA4522-2ARMZ and OPA2333AIDR, LT6023HMS8#PBF uniquely balances 1.4 V/µs slew rate, 20 µA supply current, 30 µV offset, and 3–30 V supply support - making it the only dual op-amp meeting all four criteria simultaneously for automotive and industrial MUX-buffer applications.

FAQ
What is the maximum supply voltage rating for LT6023HMS8#PBF?
The absolute maximum total supply voltage (V+ to V–) for LT6023HMS8#PBF is 36 V. Operation within the specified 3 V to 30 V range ensures full parametric performance across –40°C to 125°C. Exceeding 36 V risks permanent damage, per Absolute Maximum Ratings.
Does LT6023HMS8#PBF include a shutdown pin?
No, LT6023HMS8#PBF does not include a shutdown pin. Only the LT6023-1 variants (e.g., LT6023HDD-1#PBF) feature EN and DGND pins for shutdown control. LT6023HMS8#PBF is always active when powered; shutdown current is not specified for this part.
What is the input common-mode voltage range for LT6023HMS8#PBF?
The input common-mode voltage range for LT6023HMS8#PBF is V– + 1.2 V to V+ – 1.4 V. This allows operation with inputs extending beyond the supply rails in inverting configurations - e.g., ±13.5 V input swing on ±15 V supplies - without phase inversion or gain collapse.
Can LT6023HMS8#PBF drive capacitive loads?
Yes, LT6023HMS8#PBF can drive up to 100 pF capacitive load in unity-gain configuration. Driving larger capacitances requires adding a small series resistor (e.g., 10–50 Ω) between output and load to maintain stability, especially in higher-gain configurations where phase margin improves.
Is LT6023HMS8#PBF pin-compatible with other MSOP-8 op-amps?
LT6023HMS8#PBF follows standard MSOP-8 pinout (OUTA, –INA, +INA, V–, V+, OUTB, –INB, +INB), matching industry conventions for dual op-amps. However, functional compatibility depends on electrical specs - e.g., slew rate, offset, and supply range - not just pin count or package. Always verify circuit-level requirements before substitution.
