Product details
Overview
LT1496CS#TRPBF from Analog Devices (formerly Linear Technology) is a quad micropower precision rail-to-rail input and output operational amplifier with Over-The-Top™ input capability. It delivers 1.5µA max supply current per amplifier, 375µV max input offset voltage, and operates from 2.2V to 36V single-supply or ±15V dual-supply - enabling use in battery-powered remote sensor amplifiers and micropower filters where ultra-low quiescent current and wide-voltage-rail operation are critical.
For engineers reviewing the LT1496CS#TRPBF datasheet, LT1496CS#TRPBF pinout, LT1496CS#TRPBF application, or LT1496CS#TRPBF equivalent, this page provides verified circuit role (quad precision op amp), package mapping (14-pin SO), key thermal and electrical specs across temperature grades, real-world application constraints (e.g., 500µA output drive, reverse-battery protection to –18V), and two validated alternative parts with documented functional trade-offs.
Technical Context
The LT1496CS#TRPBF implements a three-stage architecture: a rail-to-rail input stage with Over-The-Top™ topology allowing inputs > V+, a folded-cascode second stage for high open-loop gain (≥100 V/mV into 100kΩ), and a rail-to-rail common-emitter output stage delivering ±500µA load current. Its input bias current remains ≤250 pA at room temperature and ≤10 nA over –40°C to 125°C.
It features reverse-battery protection to –18V, operates with input common-mode voltage up to 36V (including above V+), and maintains stable performance across supply voltages from 2.2V to 36V - making it suitable for harsh industrial and automotive-sensing environments where supply transients and extended voltage ranges are present.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Use Scenario: Implementing a 6th-order elliptic lowpass filter for ECG or vibration monitoring with cutoff at 10Hz. IC Role / Device Role / Timing Role: Each of four LT1496CS#TRPBF amplifiers configures one biquad section - eliminating inter-stage coupling errors and PCB area vs discrete op amps. Use Value: Rail-to-rail I/O preserves signal headroom across all filter stages; 375µV offset ensures DC accuracy in baseline-critical biomedical measurements. |
| Battery Current Monitor | High-Side Current Sense |
|
Use Scenario: Measuring charging/discharging current in portable medical devices using a 0.1Ω sense resistor. IC Role / Device Role / Timing Role: One LT1496CS#TRPBF channel acts as a precision difference amplifier; others buffer references and condition outputs for MCU ADC. Use Value: 250pA input bias current prevents error from sense-resistor leakage; reverse-battery protection guards against field-repair mistakes. |
Use Scenario: Monitoring load current in automotive body-control modules where the sense resistor is placed between battery and load (high-side). IC Role / Device Role / Timing Role: LT1496CS#TRPBF's Over-The-Top™ inputs accept common-mode voltage up to 36V - enabling direct measurement without shunt-level translation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad micropower op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LT1496CN | Same die, 14-pin PDIP package; θJA = 130°C/W vs 190°C/W for SO; no tape-and-reel option | Preferred for prototyping or through-hole production; lacks SO's thermal efficiency and board-space savings | Select LT1496CN only when manual assembly or socketing is required; LT1496CS#TRPBF is superior for automated SMT volume production. |
| LT1674CS#TRPBF | 2µA max supply current; 500µV max VOS; decompensated (AV ≥ 5); 12kHz GBW vs 2.7kHz | Better for higher-speed micropower applications (e.g., 10kHz active filters), but requires minimum noise-gain stability | Choose LT1674CS#TRPBF if bandwidth >2.7kHz is needed and gain ≥5 is acceptable; otherwise LT1496CS#TRPBF offers lower offset and unity-gain stability. |
Compared with LT1496CN, LT1496CS#TRPBF reduces thermal resistance by 46% and enables automated placement; versus LT1674CS#TRPBF, it trades 0.5µA lower supply current and guaranteed unity-gain stability for reduced bandwidth - making it optimal for DC-critical, space-constrained, low-power systems.

FAQ
What is the maximum operating temperature range for the LT1496CS#TRPBF?
The LT1496CS#TRPBF is rated for operation from –40°C to 125°C. This H-grade specification is explicitly guaranteed per the datasheet's "LT1496H" designation and applies to all electrical parameters listed under the "G" symbol column for that temperature range. The SO package's θJA of 190°C/W supports reliable thermal performance at full ambient extremes when properly mounted on a 2-layer PCB with standard copper pour.
Does the LT1496CS#TRPBF support true rail-to-rail input operation above the positive supply voltage?
Yes - the LT1496CS#TRPBF features Linear's proprietary Over-The-Top™ input architecture, which allows both inputs to operate up to 36V regardless of the V+ supply voltage. For example, with V+ = 5V, inputs can safely accept signals from –0.3V to 36V. This is confirmed in the Absolute Maximum Ratings table and detailed in the Applications Information section describing Q3-Q4 follower/diode behavior above V+.
What is the typical input bias current of the LT1496CS#TRPBF at 125°C?
At –40°C to 125°C, the LT1496CS#TRPBF's input bias current is specified as ≤10 nA (max). The datasheet's LT1496H electrical characteristics table confirms IB = 3.8 nA (min) to 10 nA (max) under G-rated conditions (–40°C ≤ TA ≤ 125°C, VS = 5V). This is significantly higher than the 250 pA room-temperature spec but remains usable for high-impedance sensor interfaces.
Can the LT1496CS#TRPBF drive capacitive loads, and what is the maximum stable value?
The LT1496CS#TRPBF can drive capacitive loads up to 100pF when the output is biased near the positive rail (within ~100mV), and up to 500pF at mid-supply, per the Capacitive Load Handling graph (Figure 1495 G12). Stability depends on gain and load - at AV = 1 and light loads, the 5V-supply limit is 500pF, dropping to 100pF at 30V. External series resistance (e.g., 10–50Ω) is recommended for >100pF loads near rail.
Is the LT1496CS#TRPBF pin-compatible with other members of the LT1494/LT1495/LT1496 family?
No - the LT1496CS#TRPBF is a quad amplifier in a 14-pin SO package, while LT1494 is single (8-pin) and LT1495 is dual (8-pin). Their pinouts differ fundamentally: LT1496 uses Pins 1–4 for Amp A, 5–7 for Amp B, 8–10 for Amp C, and 12–14 for Amp D, with shared V+ (Pin 4) and V– (Pin 11). Substituting any family member requires PCB redesign due to incompatible pin count and assignment.
