Product details
Overview
LT1356HS#PBF from Analog Devices (formerly Linear Technology) is a quad, high-speed, low-power voltage-feedback operational amplifier with 12MHz gain bandwidth, 400V/µs slew rate, and unity-gain stability. It delivers ±12V output swing into 500Ω with ±15V supplies and operates across –40°C to +125°C case temperature, making it suitable for precision data acquisition and active filtering in industrial control systems.
For engineers reviewing the LT1356HS#PBF datasheet, LT1356HS#PBF pinout, LT1356HS#PBF application, or LT1356HS#PBF equivalent, key selection criteria include guaranteed high-temperature operation (TC = –40°C to 125°C), C-Load™ capacitive-load drive capability, input offset voltage ≤2.0mV over full temperature range, and 16-pin SOIC package compatibility with automated assembly.
Technical Context
The LT1356HS#PBF employs a unique voltage-feedback topology with matched high-impedance inputs and current-feedback slewing behavior, enabling fast settling (230ns to 0.1% for 10V step) without requiring external compensation. Its single-stage design and internal RC network ensure unconditional stability with any capacitive load, including coaxial cable driving.
It features complementary NPN/PNP input stage bias cancellation, resulting in low input offset current (≤250nA) and input bias current (≤600nA) over –40°C to 125°C case temperature, while maintaining 10nV/√Hz input noise voltage and ≥96dB channel separation at ±15V supply.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth | 12MHz at ±15V - supports stable closed-loop operation up to 12MHz with unity gain. |
| Slew Rate | 400V/µs at ±15V - enables accurate reproduction of fast 10V transients with minimal distortion. |
| Input Offset Voltage | ≤2.0mV at –40°C to 125°C TC - ensures DC accuracy in wide-temperature industrial sensor interfaces. |
| Supply Current | 1.55mA per amplifier at ±15V - balances speed and power for multi-channel systems with thermal constraints. |
| Output Swing | ±12.7V into 1kΩ at ±15V - provides rail-to-rail usable dynamic range for ±12V signal conditioning. |
| Capacitive Load Drive | Stable with any value - eliminates need for isolation resistors when driving ADC input capacitance or long cables. |
| Settling Time | 230ns to 0.1%, 10V step - meets timing requirements for 1MSPS+ successive-approximation data acquisition. |
Pinout & Package
LT1356HS#PBF is housed in a 16-lead plastic SO (S16) package, 0.150-inch narrow body, with exposed pad not electrically connected. Thermal resistance θJA = 150°C/W and θJC = 30°C/W support high-reliability operation under sustained load at elevated case temperatures.

|---|---|---|
| 1, 3, 5, 12 | Inverting Input (A–, B–, C–, D–) | Differential input terminals for each of four independent amplifiers; tolerate ±10V transient differential voltage. |
| 2, 4, 6, 13 | Non-inverting Input (A+, B+, C+, D+) | High-impedance buffered inputs with matched NPN/PNP structure for low input offset current. |
| 7, 8, 10, 15 | Output (A, B, C, D) | Class-AB output stage drives 500Ω to ±12V; stable with unlimited capacitive load. |
| 9 | V+ | Positive supply rail; supports ±2.5V to ±15V operation; bypassing with 0.01–0.1µF RF capacitor recommended. |
| 16 | V– | Negative supply rail; symmetric dual supply required for specified AC performance. |
| 11, 14 | No Connect | Internally unused pins; must be left floating or tied to V– for mechanical stability (not electrically required). |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LT1356IS#PBF | Same quad architecture but rated for –40°C to +85°C ambient (TA), not case (TC); higher max VOS (1.8mV) and lower IQ (1.45mA) at 25°C. | Not qualified for >85°C ambient or high-TC environments like motor drives; suitable for commercial-grade data loggers. | Select LT1356IS#PBF only if ambient temperature stays ≤85°C and thermal margin permits lower-rated qualification. |
| ADA4891-4ARUZ | Quad 220MHz GBW, 170V/µs slew, 3.3mA/IQ, rail-to-rail output; specified for –40°C to +125°C ambient (TA), not case (TC). | Higher bandwidth but lower DC precision (2.5mV VOS max); RRO output limits headroom in ±15V systems. | Choose ADA4891-4ARUZ only when bandwidth >12MHz is mandatory and ±12V output swing is not required. |
Compared with LT1356IS#PBF and ADA4891-4ARUZ, the LT1356HS#PBF uniquely guarantees parametric performance at 125°C case temperature - critical for thermally constrained enclosures where ambient exceeds 85°C - while retaining superior DC accuracy and capacitive-load robustness.

FAQ
What is the maximum case temperature specification for LT1356HS#PBF?
The LT1356HS#PBF is guaranteed to meet all electrical specifications over a case temperature (TC) range of –40°C to +125°C, as explicitly defined in the Absolute Maximum Ratings and Electrical Characteristics tables. This differs from ambient-rated variants and enables deployment in thermally dense enclosures where junction temperature control relies on case-mounted heatsinking.
Does LT1356HS#PBF require external compensation for capacitive loads?
No, the LT1356HS#PBF does not require external compensation for capacitive loads. Its C-Load™ architecture incorporates internal frequency compensation that ensures unconditional stability with any value of capacitive load, including direct driving of ADC input capacitance, coaxial cables, or piezoelectric sensors - no series isolation resistor is needed.
What is the typical input offset voltage of LT1356HS#PBF at room temperature and full temperature range?
At 25°C, the typical input offset voltage of LT1356HS#PBF is 0.8mV (max 1.0mV). Over the full –40°C to +125°C case temperature range, the maximum input offset voltage is 2.0mV, as verified in the –40°C ≤ TC ≤ 125°C electrical characteristics table - a key differentiator for high-temperature precision applications.
Can LT1356HS#PBF drive a 500Ω load to ±12V with ±15V supplies?
Yes, the LT1356HS#PBF is specified to drive a 500Ω load to ±12V minimum with ±15V supplies, as confirmed in both the Features list ("±12V Minimum Output Swing into 500Ω") and Electrical Characteristics table (VOUT = ±12.0V min, RL = 500Ω, ±15V). This capability supports robust signal conditioning in industrial ±12V systems.
What package type and lead finish does LT1356HS#PBF use?
The LT1356HS#PBF uses a 16-lead plastic small-outline (SO) package (S16), 0.150-inch narrow body, with 100% matte tin (Pb-free) lead finish, as indicated by the "#PBF" suffix per Linear Technology's lead-free marking standard. Pin 1 identifier is a beveled corner, and the package conforms to JEDEC MS-012.
