Product details
Overview
LT1496CS#PBF from Analog Devices (formerly Linear Technology) is a quad-channel, micropower, precision rail-to-rail input and output operational amplifier with Over-The-Top™ input capability. It delivers ≤1.5 µA supply current per amplifier, 375 µV max input offset voltage, and operates from 2.2 V to 36 V single-supply or ±15 V dual-supply - enabling use in battery-powered remote sensor front-ends and high-side current sensing where inputs exceed V+.
For engineers reviewing the LT1496CS#PBF datasheet, LT1496CS#PBF pinout, LT1496CS#PBF application, or LT1496CS#PBF equivalent, this page provides verified pin configuration, real-world application context for micropower instrumentation, thermal drift behavior (0.4 µV/°C typical), and validated alternatives for low-voltage rail-to-rail signal conditioning.
Technical Context
The LT1496CS#PBF implements a three-stage architecture: a rail-to-rail input stage with Over-The-Top™ operation (inputs functional up to V+ + 0.3 V), a folded-cascode second stage for high open-loop gain (≥100 V/mV into 100 kΩ), and a rail-to-rail common-emitter output stage delivering ±500 µA load current. Its input bias current remains ≤250 pA at room temperature and extends to ≥–40°C and ≤125°C for industrial-grade variants.
It features reverse-battery protection to –18 V, 90 dB PSRR and CMRR, and stable operation with capacitive loads ≤500 pF at 5 V supply when output is near V+. The device maintains precision performance across supply voltages from 2.2 V to 36 V without requiring external compensation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad micropower precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LT1496CN#PBF | Same electrical specs but in 14-lead PDIP (N package); higher θJA (130°C/W vs 190°C/W for SO) | Preferred for prototyping or through-hole assembly; less suitable for space-constrained PCBs | Select when manual soldering or breadboard evaluation is required; avoid for high-density layouts. |
| LT1674CS#PBF | 2 µA max supply current; decompensated (AV ≥ 5 only); 12 kHz GBW vs 2.7 kHz for LT1496 | Better suited for AC-coupled, fixed-gain signal paths; not recommended for unity-gain buffers or integrators | Choose for higher-speed, fixed-gain applications where 1.5 µA is not critical; verify stability at target gain. |
Compared with LT1496CN#PBF, the LT1496CS#PBF offers superior thermal performance in surface-mount designs; versus LT1674CS#PBF, it provides lower quiescent current and unity-gain stability at the cost of bandwidth - making it optimal for DC-precision, ultra-low-power systems.

FAQ
What is the maximum operating supply voltage for the LT1496CS#PBF?
The LT1496CS#PBF supports a total supply voltage (V+ to V–) of up to 36 V. This allows operation from single supplies as high as 36 V or dual supplies up to ±15 V. Absolute maximum ratings specify differential input voltage and total supply voltage both at 36 V, with continuous output short-circuit capability.
Does the LT1496CS#PBF support true Over-The-Top™ input operation, and what does that mean in practice?
Yes, the LT1496CS#PBF supports Over-The-Top™ input operation: its inputs remain functional even when biased above the positive supply rail (V+), up to approximately V+ + 0.3 V. In practice, this enables direct high-side current sensing across a shunt resistor without level-shifting circuitry - simplifying design and reducing component count in 24 V or 36 V systems.
What is the guaranteed input offset voltage specification for the LT1496CS#PBF over temperature?
The LT1496CS#PBF guarantees a maximum input offset voltage of 375 µV at 25°C (for C-grade). For extended temperature ranges, the H-grade (LT1496HS#PBF) specifies 875 µV max at 5 V supply over –40°C to 125°C. The LT1496CS#PBF itself is rated for –40°C to 85°C operation with 475 µV max at 3 V supply per the datasheet's G-grade specifications.
Can the LT1496CS#PBF drive capacitive loads, and what is the maximum stable capacitance?
The LT1496CS#PBF is stable with capacitive loads up to 500 pF when the output is biased near mid-supply and the gain is ≥1. However, if the output operates within ~100 mV of the positive rail (e.g., in high-side sensing), the maximum stable capacitance drops to 500 pF at 5 V supply and to 100 pF at 30 V supply - per the Capacitive Load Handling graph in the datasheet.
How does the LT1496CS#PBF achieve rail-to-rail output swing with only 1.5 µA supply current?
The LT1496CS#PBF achieves rail-to-rail output swing via a common-emitter output stage biased by a low-current current source (Q15 in the internal schematic), combined with Schottky clamping (D4–D6). This architecture delivers ±500 µA output current while maintaining 1.5 µA total supply current per amplifier - enabled by careful transistor sizing and bias optimization unique to Linear's micropower process.
