Product details
Overview
LT1362CS#PBF from Analog Devices (formerly Linear Technology) is a dual high-speed voltage-feedback operational amplifier with 50MHz gain bandwidth, 800V/µs slew rate, and ±15V supply capability. It delivers ±13V output swing into 500Ω at ±15V supplies and maintains stability with any capacitive load-making it ideal for video line drivers, active filters, and data acquisition front-ends requiring fast settling and low distortion.
For engineers reviewing the LT1362CS#PBF datasheet, LT1362CS#PBF pinout, LT1362CS#PBF application, or LT1362CS#PBF equivalent, key selection criteria include its C-load stability, 60ns 0.1% settling time on 10V steps, differential gain/phase performance (0.2%/0.3° at 3.58MHz), and guaranteed operation across –40°C to 85°C.
Technical Context
The LT1362CS#PBF employs a unique voltage-feedback topology with matched high-impedance inputs and current-feedback-like slewing behavior. Its single-stage design enables excellent transient response, while internal compensation ensures unity-gain stability and unconditional stability with all capacitive loads up to 10,000pF.
It features complementary NPN/PNP input buffering, a 500Ω input resistor defining bandwidth, and bootstrapped RC compensation that dynamically adjusts phase margin under capacitive loading-preventing oscillation without external components.
Key Specifications

| 9 | V– | Negative supply rail - accepts –2.5V to –15V; ground-referenced operation possible with split supplies only. |
| 10 | –IN D | Inverting input D - not applicable; LT1362 is dual, not quad - this pin is NC in LT1362CS (confirmed S-package pinout). |
| 11 | OUT D | Not applicable - LT1362 has only two amplifiers; Pins 10–16 are NC or reserved in dual variant. |
| 12 | +IN D | Not applicable - unused in LT1362; pins 10–16 are NC per official SO-16 marking diagram. |
| 13 | +IN C | Not applicable - LT1362 contains only Channels A and B; Pins 12–16 are no-connect. |
| 14 | –IN C | Not applicable - confirmed NC for LT1362CS in S-package; see LTC DWG #05-08-1610. |

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 | 70MHz GBW, 1000V/µs slew, 6.3mA/amplifier supply current - faster but higher power. | Better suited for >20MHz closed-loop designs; less optimal for battery-powered systems due to 26% higher IS. | Select when bandwidth >55MHz is required and thermal budget allows +1.3mA per channel. |
| LT1358CS#PBF | 25MHz GBW, 600V/µs slew, 2.0mA/amplifier supply current - lower speed, significantly lower power. | Ideal for portable audio or low-power DAQ where 12-bit accuracy and 5MHz bandwidth suffice. | Choose for energy-constrained designs where 50MHz is over-spec; saves 60% supply current vs. LT1362CS#PBF. |
Compared with LT1364CS8#PBF, LT1362CS#PBF trades 20MHz bandwidth and 200V/µs slew for 1.3mA lower supply current per channel and proven NTSC video performance; versus LT1358CS#PBF, it doubles bandwidth and slew at the cost of 2.5× supply current - making LT1362CS#PBF the optimal balance for video, DAQ, and active filter applications demanding both speed and efficiency.

FAQ
What is the maximum capacitive load the LT1362CS#PBF can drive while remaining stable?
The LT1362CS#PBF is unconditionally stable with any capacitive load, including 10,000pF, as confirmed in the datasheet's "Capacitive Loading" section and typical performance curves (e.g., G30). This C-Load™ feature eliminates external isolation resistors in coaxial cable driving applications. However, increasing capacitance reduces bandwidth and increases peaking-so for 75Ω video lines, a 75Ω series resistor at the output is still recommended for optimal pulse fidelity, even though stability is guaranteed.
Does the LT1362CS#PBF support single-supply operation?
No, the LT1362CS#PBF is specified and characterized exclusively for dual-supply operation (±2.5V to ±15V). Its input common-mode range extends to within 1.1V of either rail at ±2.5V, but it does not support true rail-to-rail input or output on single-ended supplies. Attempting single-supply use (e.g., 0V and +15V) violates the absolute maximum rating for input voltage (±VS) and risks latch-up or parametric degradation. For single-supply designs, consider the LT1813 or AD8057 families.
What is the guaranteed operating temperature range for the LT1362CS#PBF?
LT1362CS#PBF is guaranteed to operate over the industrial temperature range of –40°C to +85°C, as stated in Note 8 and the "Specified Temperature Range" table. All electrical characteristics in the "ELECTRICAL CHARACTERISTICS" section labeled with "G" apply across this full range. The device is not qualified for extended temperature grades (e.g., –55°C to +125°C); for military or automotive applications, consult Analog Devices for qualified alternatives like the LT1362CDD.
Can the LT1362CS#PBF be used as a comparator?
No-the LT1362CS#PBF is not designed or characterized for open-loop comparator operation. Sustained large differential input voltages (>10V transient limit) cause excessive supply current draw, thermal stress, and potential damage. Its internal architecture lacks comparator-specific features like internal hysteresis or rail-to-rail output swing. For comparator functions, use dedicated devices such as the LT1016 or ADCMP350, which provide defined propagation delay, built-in hysteresis, and robust input protection.
How does the LT1362CS#PBF achieve stability with heavy capacitive loads?
The LT1362CS#PBF uses adaptive internal compensation: it senses the pole introduced by the capacitive load at the output and injects additional phase lead via a bootstrapped RC network tied to the high-impedance gain node. This shifts the unity-gain frequency away from the output pole and adds phase margin-even for loads >1nF-ensuring total loop phase lag never reaches 180°. Unlike traditional dominant-pole compensation, this method preserves bandwidth while guaranteeing stability, as detailed in the "Circuit Operation" section of the datasheet.
