Product details
Overview
LT1496IN#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 low-power instrumentation.
For engineers reviewing the LT1496IN#PBF datasheet, LT1496IN#PBF pinout, LT1496IN#PBF application, or LT1496IN#PBF equivalent, this page provides verified pin configuration, real-world design meaning of key specs (e.g., 36 V total supply range, –40°C to 125°C extended temperature grade), and validated alternative options for micropower precision op amp selection.
Technical Context
The LT1496IN#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 supporting ±500 µA load current. Its input bias current remains ≤250 pA at room temperature and ≤10 nA over full –40°C to 125°C range.
It features reverse-battery protection to –18 V, 90 dB PSRR and CMRR at DC, and stable operation with capacitive loads ≤100 pF when output is near rail. The device is characterized and guaranteed across –40°C to 125°C (H-grade), with input offset drift as low as 0.4 µV/°C typical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current per Amp | ≤1.5 µA - enables multi-year operation on coin-cell batteries in always-on sensor nodes. |
| Input Offset Voltage | ≤375 µV max at 25°C - ensures sub-1 mV error in 12-bit ADC front-ends without trimming. |
| Total Supply Range | 2.2 V to 36 V - supports direct connection to 24 V industrial buses or 3 V Li-ion systems without regulators. |
| Rail-to-Rail I/O | Input extends to –0.3 V below V– and >V+; output swings within 35 mV of rails - maximizes dynamic range in low-voltage systems. |
| Operating Temp Range | –40°C to 125°C - qualified for under-hood automotive, industrial control, and downhole sensing applications. |
| Input Bias Current | ≤250 pA (25°C), ≤10 nA (125°C) - permits use with >1 MΩ source impedances without significant offset error. |
| Open-Loop Gain | ≥100 V/mV into 100 kΩ - guarantees <0.1% gain error in unity-gain buffer or G=10 configurations. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar micropower precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LT1674CS#PBF | 2 µA max supply current; decompensated (AV ≥ 5 only); 12 kHz GBW vs LT1496IN#PBF's 2.7 kHz. | Requires minimum gain of 5; unsuitable for unity-gain buffers or integrators where stability is critical. | Select LT1674CS#PBF only when higher speed and fixed-gain >5 configurations are needed; verify phase margin with load. |
| LT1782IS6#TRMPBF | SOT-23-6 single-channel; 55 µA supply current; 800 µV VOS max; includes shutdown pin. | Higher power and offset; smaller footprint but no quad integration - increases board area and component count for multi-channel needs. | Choose LT1782IS6#TRMPBF for space-constrained single-channel designs requiring shutdown; avoid for quad-sensing or ultra-low-IQ systems. |
Compared with LT1496IN#PBF, LT1674CS#PBF trades guaranteed unity-gain stability for higher bandwidth and LT1782IS6#TRMPBF sacrifices micropower performance for compact size and shutdown control - making LT1496IN#PBF the optimal choice for quad-channel, sub-2 µA, rail-to-rail precision sensing.

FAQ
What is the maximum supply voltage rating for LT1496IN#PBF?
The LT1496IN#PBF has an absolute maximum total supply voltage (V+ to V–) rating of 36 V. It is fully specified and guaranteed to operate over a supply range of 2.2 V to 36 V single supply or ±15 V dual supply. Exceeding 36 V risks permanent damage, and operation below 2.2 V may result in undefined behavior or failure to meet datasheet specifications.
Does LT1496IN#PBF support true Over-The-Top™ input operation, and what does that mean in practice?
Yes, LT1496IN#PBF supports true Over-The-Top™ input operation: its inputs remain functional and linear even when driven up to ~0.3 V above the V+ rail. In practice, this enables high-side current sensing directly across a shunt resistor placed between V+ and load - eliminating level-shifting ICs, isolated supplies, or complex resistor networks required by conventional op amps.
What is the guaranteed operating temperature range for LT1496IN#PBF?
The LT1496IN#PBF is an H-grade device with a guaranteed operating temperature range of –40°C to +125°C. All electrical specifications - including supply current (≤1.5 µA), input offset voltage (≤875 µV), and open-loop gain (≥4 V/mV) - are tested and warranted across this full range, making it suitable for under-hood automotive, industrial control, and downhole applications.
Can LT1496IN#PBF drive capacitive loads, and what is the maximum stable value?
LT1496IN#PBF is stable with capacitive loads ≤100 pF when the output is biased near mid-supply. However, stability degrades when the output operates within ~100 mV of either rail: at 5 V supply, max stable load capacitance drops to <500 pF; at 30 V supply, it falls below 100 pF. For larger loads, external isolation resistors (e.g., 10–100 Ω in series with output) are recommended.
How does LT1496IN#PBF handle reverse battery conditions?
LT1496IN#PBF is reverse-battery protected to –18 V on the V+ pin. Under –18 V reverse condition with inputs grounded and outputs open, supply current remains <100 nA. In typical single-supply applications with ground-referenced loads, no external protection is needed - though external current-limiting resistors (<1 kΩ) are advised if inputs or outputs may be pulled negative during fault conditions.
