Product details
Overview
LT1364CN8#PBF from Analog Devices (formerly Linear Technology) is a dual high-speed voltage-feedback operational amplifier with 70MHz gain bandwidth, 1000V/µs slew rate, and unity-gain stability. It delivers ±7.5V output swing into 150Ω with ±15V supplies and drives capacitive loads without external compensation-making it ideal for video line drivers, active filters, and data acquisition front-ends.
For engineers reviewing the LT1364CN8#PBF datasheet, LT1364CN8#PBF pinout, LT1364CN8#PBF application, or LT1364CN8#PBF equivalent, key selection criteria include guaranteed 0.1% settling time (50ns), differential gain/phase performance (0.06%/0.04° at 3.58MHz), input offset voltage ≤1.5mV, and operation across ±2.5V to ±15V supplies.
Technical Context
The LT1364CN8#PBF employs a hybrid voltage-feedback topology with matched high-impedance inputs and current-feedback–like slewing behavior. Its single-stage design enables fast settling (50ns to 0.1%) and excellent large-signal transient response, critical for precision ADC buffering and pulse amplification.
It features internal C-Load™ compensation enabling unconditional stability with any capacitive load-including coaxial cables-and maintains ≥90dB PSRR and ≥84dB CMRR across ±2.5V to ±15V supply ranges, supporting robust operation in noisy industrial signal chains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth | 70MHz at ±15V - supports closed-loop designs up to 10MHz with gain ≥7, suitable for high-fidelity video and RF IF stages. |
| Slew Rate | 1000V/µs at ±15V - enables full-scale 10V step response in <10ns, essential for fast DAC output buffering. |
| Input Offset Voltage | ≤1.5mV max at ±15V - ensures DC accuracy in instrumentation amplifier front-ends without trimming. |
| Output Current | ≥50mA min into ±7.5V - drives 150Ω video loads or multiple logic inputs directly, eliminating buffer stages. |
| Settling Time | 50ns to 0.1% for 10V step - meets timing requirements of 20MSPS+ data acquisition systems. |
| Differential Gain/Phase | 0.06% / 0.04° at 3.58MHz, RL=150Ω - satisfies NTSC/PAL broadcast video fidelity standards. |
| Supply Current | 7.5mA max per amplifier - balances speed and power for dual-channel portable test equipment. |
Pinout & Package
LT1364CN8#PBF is housed in an 8-lead PDIP (N8 package), 0.300" wide, with JEDEC-standard pinout and through-hole mounting compatibility.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | –IN A | Inverting input of Amplifier A; high-impedance node requiring matched source impedance for DC accuracy. |
| 2 | +IN A | Non-inverting input of Amplifier A; complementary NPN/PNP input stage enables bipolar input voltage range. |
| 3 | V+ | Positive supply rail; supports operation from ±2.5V to ±15V (36V total); bypass with 0.01–0.1µF near pin. |
| 4 | OUT A | Amplifier A output; capable of ±7.5V swing into 150Ω and stable with >1nF capacitive loads. |
| 5 | OUT B | Amplifier B output; fully independent channel with identical AC/DC specs and load drive capability. |
| 6 | V– | Negative supply rail; referenced to system ground; requires low-ESR bulk capacitance for high-current transients. |
| 7 | –IN B | Inverting input of Amplifier B; shares same input structure and bias current cancellation as Pin 1. |
| 8 | +IN B | Non-inverting input of Amplifier B; enables dual-channel instrumentation or parallel gain stages. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed dual op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LT1364CS8#PBF | Same electrical specs, but in 8-lead SOIC (S8) package - 190°C/W θJA vs 130°C/W for PDIP. | Better for space-constrained PCBs; requires reflow soldering and lacks through-hole mechanical robustness. | Select LT1364CS8#PBF only when board area is constrained and thermal management via copper pour is feasible. |
| LT1361CS8#PBF | 50MHz GBW, 800V/µs slew rate, 4mA supply current per amp - lower speed and power than LT1364CN8#PBF. | Suitable for cost-sensitive, moderate-bandwidth applications where 70MHz is unnecessary. | Choose LT1361CS8#PBF when 50MHz bandwidth suffices and supply current reduction is prioritized over settling speed. |
Compared with LT1364CS8#PBF, the LT1364CN8#PBF offers superior thermal resistance (130°C/W vs 190°C/W) for high-output-drive applications, while LT1361CS8#PBF trades 20MHz bandwidth and 200V/µs slew rate for 3.5mA lower per-amplifier current - making it viable only where full LT1364 performance is not required.

FAQ
What is the maximum capacitive load the LT1364CN8#PBF can drive stably?
The LT1364CN8#PBF features C-Load™ compensation and is unconditionally stable with any capacitive load - including infinite capacitance. Performance degrades gracefully: bandwidth and phase margin decrease with increasing load, causing peaking in frequency and transient response (e.g., 62% overshoot at 200pF), but oscillation does not occur. For optimal pulse fidelity with coaxial cable, use a 75Ω series resistor at the output.
Does the LT1364CN8#PBF require external compensation for unity-gain operation?
No. The LT1364CN8#PBF is unity-gain stable and requires no external compensation components in gain = 1 configurations. Its internal compensation network ensures ≥45° phase margin across all supply voltages (±2.5V to ±15V) and temperatures (–40°C to +85°C), enabling straightforward use as a voltage follower in sensor interfaces and signal routing.
What is the guaranteed input offset voltage specification for LT1364CN8#PBF over temperature?
The LT1364CN8#PBF guarantees input offset voltage ≤1.5mV at ±15V, ±5V, and ±2.5V supplies at TA = 25°C. Over the full –40°C to +85°C operating range, the typical VOS drift is 10–13µV/°C, and the maximum VOS remains ≤2.5mV (per datasheet Grade G specifications). This ensures predictable DC error in precision instrumentation designs.
Can the LT1364CN8#PBF operate from a single +5V supply?
Yes - the LT1364CN8#PBF supports single-supply operation. With V+ = +5V and V– = 0V, it maintains rail-to-rail input common-mode range (0V to +3.4V) and delivers ±2.5V output swing into 150Ω (i.e., 0.5V to +4.5V). However, its specified AC performance (e.g., 70MHz GBW, 1000V/µs SR) is characterized only for split supplies; at +5V, GBW drops to ~50MHz and SR to ~450V/µs.
How does the LT1364CN8#PBF compare to the LT1363 in terms of pin compatibility and performance?
The LT1364CN8#PBF (dual) and LT1363 (single) share identical amplifier core architecture, electrical specs, and pinout per channel - but differ in package and channel count. The LT1363 uses an 8-lead SOIC or PDIP with pins 1–4 and 5–8 mapped identically to one half of the LT1364CN8#PBF. Thus, a single LT1364CN8#PBF replaces two LT1363s in dual-channel layouts, reducing component count and inter-channel mismatch.
