Product details
Overview
LT1413S8#PBF from Analog Devices (acquired Linear Technology) is a dual, single-supply precision operational amplifier optimized for 5V systems. It features ±13.8V input voltage range, 380µV max input offset voltage (S8 package), 0.8nA max input offset current, 480µA max supply current per amplifier, and 950kHz gain-bandwidth product - enabling high-accuracy signal conditioning in battery-powered instrumentation and sensor interfaces.
For engineers reviewing the LT1413S8#PBF datasheet, LT1413S8#PBF pinout, LT1413S8#PBF application, or LT1413S8#PBF equivalent, key selection criteria include guaranteed phase reversal protection, rail-to-rail output sinking to within 10mV of ground at 1mA load, and validated performance across –40°C to 85°C without derating.
Technical Context
The LT1413S8#PBF implements a proprietary input stage with 400Ω series resistors and dedicated phase reversal protection circuitry (Q21/Q22/Q27/Q28), enabling safe operation with inputs up to 5V below ground. Its architecture delivers 140dB channel separation and 118dB PSRR at 25°C, supporting tightly coupled dual-amplifier topologies like instrumentation amplifiers without crosstalk-induced error.
Unlike legacy single-supply op amps (e.g., LM358), the LT1413S8#PBF avoids output phase reversal when inputs go negative - critical for closed-loop stability in strain gauge bridges and active filters operating near ground-referenced signals.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | 380µV max (S8 package, 5V/0V, 25°C) - enables sub-mV accuracy in 10-bit ADC front-ends without trimming |
| Supply Current per Amplifier | 480µA max - supports >10-year battery life in portable medical sensors |
| Gain-Bandwidth Product | 950kHz - sufficient for 10kHz active low-pass filtering with 10× gain margin |
| Output Low Voltage (1mA sink) | 350mV max - ensures TTL-compatible logic-level detection without pull-down resistors |
| Common-Mode Input Range | –0.3V to +3.8V (5V/0V supply) - accepts ground-referenced bridge outputs directly |
| PSRR | 118dB - rejects >99.99% of 5V rail noise in noisy embedded power domains |
| Channel Separation | 140dB - prevents coupling between dual channels in differential instrumentation amplifier configurations |
Pinout & Package
S8 package: 8-lead plastic SOIC, industry-standard LT1013DS8 pinout (not DIP-compatible). Thermal resistance θJA = 130°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | –IN A | Inverting input of amplifier A - protected against phase reversal down to –1.5V |
| 2 | +IN A | Non-inverting input of amplifier A - 500MΩ common-mode input resistance |
| 3 | V– | Negative supply terminal - accepts 0V (ground) for true single-supply operation |
| 4 | OUT A | Amplifier A output - sinks to 10mV above ground at no load, 350mV at 1mA |
| 5 | OUT B | Amplifier B output - electrically isolated from OUT A with 140dB separation |
| 6 | +IN B | Non-inverting input of amplifier B - matched bias current (≤18nA) to +IN A |
| 7 | –IN B | Inverting input of amplifier B - identical phase reversal protection as –IN A |
| 8 | V+ | Positive supply terminal - operates from 2.85V to ±22V (dual) or 5V/0V (single) |
Key Features
| Feature | Design Value |
|---|---|
| Phase reversal protection | Guaranteed non-inverting output behavior even with inputs at –1.5V (5V/0V supply), preventing servo lock-up |
| Ground-sinking output | Outputs drive to ≤350mV above ground at 1mA load - eliminates need for external pull-down resistors |
| Input overvoltage protection | 400Ω series resistors limit input current to safe levels even with –5V applied to inputs |
| Low 0.1Hz–10Hz noise | 0.55µVP-P - critical for DC-coupled strain gauge and thermopile amplification |
| High CMRR | 101dB min (25°C) - rejects common-mode interference in unshielded industrial sensor wiring |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual, single-supply precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LT1013DS8#PBF | Higher 1.5mV max VOS, 1.2µA supply current, no phase reversal protection | Lacks guaranteed negative-input tolerance - unsuitable for bridge circuits with offset drift | Select only for cost-sensitive, non-critical DC amplification where VOS drift is acceptable |
| OP2177ARZ-REEL7 | Lower 25µV max VOS, 400µA supply current, but requires ±5V minimum supply | Cannot operate on 5V/0V - needs dual-rail generation, increasing BOM count and power loss | Prefer when ultra-low offset dominates design requirements and dual supply is available |
Compared with LT1013DS8#PBF, the LT1413S8#PBF trades modest cost increase for guaranteed phase reversal immunity and 3× lower offset voltage; versus OP2177ARZ-REEL7, it sacrifices 10× offset improvement to enable true single-supply simplicity and robustness in ground-referenced sensor systems.

FAQ
What is the maximum input voltage range for LT1413S8#PBF when operated on a 5V/0V supply?
The LT1413S8#PBF supports an input common-mode voltage range of –0.3V to +3.8V under 5V/0V supply conditions. This allows direct connection of ground-referenced transducer outputs while maintaining phase reversal protection down to –1.5V - a capability confirmed in the LT1413S8#PBF datasheet Figure TA23 and Absolute Maximum Ratings table.
Does LT1413S8#PBF require external pull-down resistors for output grounding?
No. The LT1413S8#PBF output can sink current to within 10mV of ground at no load and 350mV at 1mA, eliminating the need for external pull-down resistors. This feature is explicitly documented in the "Single Supply Operation" section and Electrical Characteristics table for LT1413S8#PBF under "Maximum Output Voltage Swing - Output Low".
Can LT1413S8#PBF be used as a comparator with TTL output compatibility?
Yes. The LT1413S8#PBF's output swings from ≤25mV (low) to ≥4.1V (high) under 5V/0V supply, meeting TTL logic thresholds. Its 50µs response time for 10mV overdrive (Figure TA24/TA25) and phase reversal immunity make it suitable for precision comparator roles - a use case explicitly called out in the Applications Information section of the LT1413S8#PBF datasheet.
What is the guaranteed input offset voltage specification for LT1413S8#PBF across temperature?
The LT1413S8#PBF has a guaranteed maximum input offset voltage of 580µV over the full –40°C to +85°C operating range (Grade C, Table on page 4, row "LT1413S8"). This value includes drift contribution and is validated by design correlation per Note 7 - distinct from the 380µV max at 25°C specified for the same LT1413S8#PBF part number.
Is LT1413S8#PBF pin-compatible with LT1013DS8#PBF?
Yes. The LT1413S8#PBF uses the industry-standard LT1013DS8 SO-8 pinout (not the DIP configuration), as explicitly stated in the "NOTE" box adjacent to the S8 PACKAGE diagram. Both share identical pin functions: Pin 1 (–IN A), Pin 2 (+IN A), Pin 3 (V–), Pin 4 (OUT A), Pin 5 (OUT B), Pin 6 (+IN B), Pin 7 (–IN B), Pin 8 (V+).
