Product details
Overview
LT1359IS14#PBF from Analog Devices (formerly Linear Technology) is a quad high-speed voltage-feedback operational amplifier with 25MHz gain bandwidth, 600V/µs slew rate, and ±15V supply capability. It delivers ±12.5V output swing into 500Ω, features C-Load™ stability with any capacitive load, and is specified over –40°C to 85°C for industrial data acquisition and active filter applications.
For engineers reviewing the LT1359IS14#PBF datasheet, LT1359IS14#PBF pinout, LT1359IS14#PBF application, or LT1359IS14#PBF equivalent, key selection criteria include guaranteed 0.1% settling in 115ns at ±15V, input offset voltage ≤0.8mV (max), unity-gain stability, and SO-14 package compatibility with space-constrained PCB layouts.
Technical Context
The LT1359IS14#PBF employs a hybrid voltage-feedback topology delivering current-feedback slewing performance. Its matched high-impedance inputs and single-stage design enable fast settling (115ns to 0.1%, 10V step) and wideband operation up to 25MHz GBW at ±15V supplies.
It integrates complementary NPN/PNP input buffering and bootstrapped RC compensation to maintain stability with unlimited capacitive loading - a critical feature for photodiode amplification, DAC I-to-V conversion, and coaxial cable driving without external isolation resistors.
Key Specifications

|---|---|
| Gain Bandwidth | 25MHz at ±15V - supports closed-loop designs up to ~2.5MHz at gain=10 without phase margin erosion |
| Slew Rate | 600V/µs at ±15V - enables full-scale 10V transitions in <17ns, critical for fast data acquisition front-ends |
| Input Offset Voltage | ≤0.8mV max at TA = –40°C to 85°C - ensures DC accuracy in precision instrumentation without trimming |
| Supply Current | 2.5mA per amplifier max at ±15V - enables quad-channel high-speed amplification within 10mA total budget |
| Output Swing | ±12.5V into 500Ω at ±15V - drives standard analog interface loads directly without level-shifting circuitry |
| Settling Time | 115ns to 0.1%, 10V step - meets 10-bit+ system timing budgets in multiplexed ADC driver applications |
| Input Noise | 8nV/√Hz at 10kHz - preserves SNR in low-level signal conditioning paths such as photodiode transimpedance stages |
Pinout & Package
LT1359IS14#PBF is housed in a 14-lead plastic SO (Small Outline) package with 1.27mm pitch, JEDEC MS-012AC compliant, 8.74mm × 3.99mm body size, and 1.75mm max height. Thermal resistance θJA = 160°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - capable of ±12.5V swing into 500Ω; requires local 0.1µF bypass to V+ |
| 2 | –IN A | Inverting input A - high-impedance node; balanced source resistance recommended for DC accuracy |
| 3 | +IN A | Non-inverting input A - matched to –IN A for common-mode rejection; withstands ±10V transient differential |
| 4 | +IN B | Non-inverting input B - electrically isolated from A/C/D sections; shares V+ and V– rails |
| 5 | –IN B | Inverting input B - independent bias current path; polarity may be positive or negative due to NPN/PNP matching |
| 6 | OUT B | Amplifier B output - identical drive capability to OUT A; channel separation >98dB prevents crosstalk |
| 7 | OUT C | Amplifier C output - fully independent stage; no shared internal nodes with A or B |
| 8 | V– | Negative supply rail - must be decoupled with 1µF tantalum + 0.1µF ceramic near pin |
| 9 | –IN D | Inverting input D - fourth amplifier input; layout symmetry critical for quad-channel matching |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad high-speed op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LT1363CS14#PBF | Higher bandwidth (50MHz), higher supply current (4mA/amp), VOS = 1mV max | Better for >5MHz closed-loop designs; less suitable for battery-powered systems due to 2× IS | Select when bandwidth headroom >2× required and power budget allows |
| OPA4350UA | Rail-to-rail input/output, lower VOS (0.15mV typ), but GBW = 38MHz, SR = 20V/µs, not C-Load™ stable | Superior DC precision and supply flexibility; requires external compensation for >100pF loads | Select for low-voltage (<5V) precision apps where capacitive load <100pF |
Compared with LT1359IS14#PBF, LT1363CS14#PBF trades 2× power for 2× bandwidth and faster settling, while OPA4350UA sacrifices high-speed stability and slew for rail-to-rail operation and microvolt-level offset - making LT1359IS14#PBF optimal for industrial ±15V systems requiring robust capacitive-load tolerance and sub-120ns settling.

FAQ
What is the maximum capacitive load the LT1359IS14#PBF can drive without instability?
The LT1359IS14#PBF is C-Load™ stable and operates unconditionally stable with any capacitive load - including direct connection to coaxial cables or large (>10nF) filter capacitors. No external isolation resistor or compensation network is required, though bandwidth and phase margin decrease progressively with increasing capacitance, resulting in predictable peaking that remains bounded.
Does the LT1359IS14#PBF support ±5V operation, and what performance changes occur?
Yes, the LT1359IS14#PBF is fully specified for ±5V operation. At ±5V supplies, slew rate drops to 220V/µs (min), gain bandwidth reduces to 22MHz (typ), and output swing is ±3.0V into 150Ω. Input offset voltage remains ≤0.8mV, and settling time increases to 110ns (0.1%, 5V step), maintaining suitability for low-voltage portable instrumentation.
How does the LT1359IS14#PBF achieve its high slew rate while maintaining low supply current?
The LT1359IS14#PBF achieves 600V/µs slew rate at only 2.5mA per amplifier by using a unique voltage-feedback topology with current-feedback slewing behavior. Its input stage generates slew-current proportional to differential input voltage divided by a 500Ω internal resistor, enabling high dV/dt without continuous high quiescent current - unlike conventional current-feedback op-amps.
Is the LT1359IS14#PBF pin-compatible with standard quad op-amp SO-14 packages?
Yes, the LT1359IS14#PBF uses the industry-standard 14-lead SO (Small Outline) package with 1.27mm pitch and JEDEC MS-012AC footprint. Pin assignments match conventional quad op-amp layouts: pins 1–3 (A), 4–6 (B), 7 (C out), 8 (V–), 9–10 (D), 11–13 (C), 14 (V+), enabling drop-in replacement in existing designs using SO-14 quad op-amps.
What is the guaranteed input offset voltage specification for LT1359IS14#PBF over temperature?
The LT1359IS14#PBF guarantees input offset voltage ≤0.8mV maximum across the full operating temperature range of –40°C to +85°C at ±15V and ±5V supplies. Input offset drift is further limited to 5–8µV/°C, ensuring minimal drift-induced error in precision DC-coupled signal chains over industrial temperature excursions.
