Product details
Overview
LT6020HMS8#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 5 V/µs slew rate, 30 µV max input offset voltage, 0.5 µV/°C max offset drift, 400 kHz gain-bandwidth product, and 100 µA/amplifier supply current - enabling high-accuracy signal conditioning in low-power multiplexed ADC and DAC buffer applications.
For engineers reviewing the LT6020HMS8#PBF datasheet, LT6020HMS8#PBF pinout, LT6020HMS8#PBF application, or LT6020HMS8#PBF equivalent, key selection criteria include guaranteed H-grade temperature performance, rail-to-rail output swing (≤190 mV from rails at 125°C), low 1.1 µVP-P 0.1–10 Hz noise, absence of output phase inversion, and compatibility with 3 V to 30 V supplies.
Technical Context
The LT6020HMS8#PBF employs a proprietary input stage combining NPN and PNP differential pairs to maintain high dynamic input impedance during large input transients (up to ±5 V), eliminating back-to-back diode conduction common in bipolar op amps. This architecture enables fast settling (13.8 µs to 0.0015% for 5 V step) without sacrificing precision specs like CMRR (120 dB) or PSRR (118 dB).
Its enhanced slew rate scales with input step size (2.4 V/µs for 5 V step; 5 V/µs for 10 V step) while preserving low quiescent current - a trade-off typically unattainable in conventional micropower amplifiers. The device operates without rail-to-rail inputs (VICM = V– +1.2 V to V+ –1.4 V), yet achieves rail-to-rail output via Class AB drive stage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Slew Rate | 5 V/µs (10 V step, TA ≤ 85°C); enables fast settling in MUX-driven data acquisition |
| Input Offset Voltage | 30 µV max (TA = –40°C to 125°C, MS8 package); ensures <1 LSB error in 18-bit DAC buffering |
| Offset Drift | 0.5 µV/°C max (MS8); supports stable DC-coupled sensor interfaces across industrial temp range |
| Supply Current | 100 µA per amplifier (TA ≤ 125°C); allows battery-powered operation for >10 years in sleep-mode systems |
| Gain-Bandwidth | 400 kHz (fO = 10 kHz); sufficient for anti-aliasing and reconstruction filters up to ~40 kHz |
| Rail-to-Rail Output | VOH ≤ 190 mV from V+, VOL ≤ 300 mV from V– (RL = 10 kΩ, TA ≤ 125°C); maximizes dynamic range in single-supply systems |
| Input Noise | 1.1 µVP-P (0.1–10 Hz); critical for low-frequency precision instrumentation |
Pinout & Package
LT6020HMS8#PBF uses the 8-lead plastic MSOP (MS8) package with θJA = 163°C/W. Exposed pad is not electrically connected and may be left floating or grounded for thermal enhancement.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT A) | Amplifier A output | Drives load directly; rail-to-rail swing supports full-scale DAC output buffering |
| 2 (–IN A) | Inverting input A | High-impedance node (17 GΩ common-mode); accepts signals within V– +1.2 V to V+ –1.4 V |
| 3 (+IN A) | Noninverting input A | Same voltage range as –IN A; used for unity-gain followers or noninverting gain stages |
| 4 (V–) | Negative supply rail | Must be bypassed with ≥0.1 µF capacitor; exposed pad internally tied to this pin |
| 5 (V+) | Positive supply rail | Accepts 3 V to 30 V; PSRR ≥118 dB ensures immunity to supply ripple |
| 6 (OUT B) | Amplifier B output | Independent channel; enables dual-channel signal paths without cross-talk degradation |
| 7 (–IN B) | Inverting input B | Electrically isolated from Channel A; supports independent feedback networks |
| 8 (+IN B) | Noninverting input B | Matches Channel A specs; allows simultaneous dual-sensor conditioning |
Key Features
| Feature | Design Value |
|---|---|
| No output phase inversion | Guaranteed operation without polarity reversal even when inputs exceed VICM limits |
| High dynamic input impedance | Maintains >17 GΩ input resistance during ±5 V input steps - prevents MUX-induced settling errors |
| Fast recovery from overdrive | Recovery time <100 µs after ±14.5 V output saturation - critical for precision comparator-like use |
| Low 0.1–10 Hz noise | 1.1 µVP-P enables sub-µV-level DC stability in thermocouple and strain gauge amplifiers |
| Wide supply range | Operates from 3 V (single-cell Li-ion) to 30 V (industrial bus), simplifying power architecture |
Applications
| 18-Bit DAC Amplifier | Multiplexed ADC Driver |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2333AIDR | Zero-drift architecture (0.02 µV/°C drift), lower 0.65 µVP-P noise, but slower 1.6 V/µs slew rate and 350 kHz GBW | Better for ultra-stable DC offsets; unsuitable for >100 kHz transient response requirements | Select when long-term DC accuracy outweighs speed; avoid if MUX settling or DAC slewing dominates design |
| AD8628ARZ-REEL7 | Zero-drift, 1.1 µVP-P noise, 2.5 V/µs slew, 2.5 MHz GBW, but 1.2 mA supply current - 12× higher than LT6020HMS8#PBF | Superior bandwidth and speed; incompatible with multi-year battery operation | Choose for high-speed precision tasks where power budget allows; reject for energy-constrained edge nodes |
Compared with OPA2333AIDR and AD8628ARZ-REEL7, the LT6020HMS8#PBF uniquely balances micropower operation (100 µA), precision (30 µV offset), and speed (5 V/µs) - making it optimal for battery-powered, multiplexed, high-resolution data acquisition where all three parameters are simultaneously constrained.

FAQ
What is the maximum operating temperature range for the LT6020HMS8#PBF?
The LT6020HMS8#PBF is rated for operation from –40°C to +125°C (H-grade). This extended temperature range is validated per manufacturer specifications and applies to all electrical parameters listed in the datasheet under "Electrical Characteristics" for the MS8 package, including input offset voltage (30 µV max), offset drift (0.5 µV/°C max), and output swing (≤300 mV from rails).
Does the LT6020HMS8#PBF support rail-to-rail input operation?
No, the LT6020HMS8#PBF does not support rail-to-rail input operation. Its common-mode input range is specified as V– +1.2 V to V+ –1.4 V. However, it does provide rail-to-rail output swing (within 190 mV of V+ and 300 mV of V– at 125°C), making it suitable for single-supply applications where output headroom is critical but input signals remain within the defined VICM window.
How does the slew rate of the LT6020HMS8#PBF vary with input step size?
The LT6020HMS8#PBF exhibits step-size-dependent slew rate: 2.4 V/µs for a 5 V input step and 5 V/µs for a 10 V input step (both measured at TA ≤ 85°C). This behavior stems from its proprietary input stage and is documented in the "Typical Performance Characteristics" section. At smaller steps (e.g., 0.7 V), slew rate drops to 0.2 V/µs - a key consideration when selecting feedback components for transient response-critical applications.
Is the LT6020HMS8#PBF pin-compatible with the LT6020-1 variants?
No, the LT6020HMS8#PBF is not pin-compatible with LT6020-1 variants. The LT6020HMS8#PBF is the standard dual op amp in 8-lead MSOP with no shutdown functionality, while LT6020-1 parts (e.g., LT6020HDD-1#PBF) use a 10-lead DFN package and include EN and DGND pins for shutdown control. Pin count, layout, and function differ fundamentally - PCB redesign is required for substitution.
What is the typical input bias current of the LT6020HMS8#PBF at 125°C?
The typical input bias current of the LT6020HMS8#PBF at 125°C is ±1 nA, with a maximum of ±10 nA across the full temperature range (–40°C to 125°C). This value is confirmed in the "Electrical Characteristics" table on page 3 of the datasheet under IB parameter for MS8 package, and reflects the bipolar input stage's behavior under worst-case thermal stress.
