LT1216CS - 23MHz Quad Precision Op Amp | Analog Devices
MPN： LT1216CS ✗ 停產LT1216CS 概覽
An operational amplifier is an analog building block used to amplify voltage differences, buffer signals, drive analog-to-digital converters, and implement active filters. The LT1216 belongs to the precision-op-amp hierarchy, where accurate DC behavior and fast large-signal response are useful in instrumentation, industrial measurement, communications, and test systems. It is a general-purpose precision amplifier rather than a power regulator or switching device.
The verified specifications identify a 23 MHz gain-bandwidth product, 50 V/µs slew rate, and fast settling of 250 ns to 0.01% for a 2 V step. The manufacturer describes the LT1216 as a quad version of the LT1215 dual amplifier and states that the devices operate from any supply greater than 2.5 V and less than 36 V total. These figures support both precision low-frequency work and higher-bandwidth signal conditioning.
The LT1216 family emphasizes DC precision and high-frequency performance. Its 23 MHz bandwidth provides useful signal amplification bandwidth, while the 50 V/µs slew rate improves response to step-like signals. The manufacturer’s published settling data gives 250 ns typical settling to 0.01% after a 2 V step and 480 ns after a 10 V step to 1 mV, making circuit simulation and feedback-loop design important.
Typical uses include instrumentation amplifiers, active filters, buffer stages, communication interface circuits, data-converter front ends, and precision control systems. The quad format can reduce the number of external amplifier packages when four independent channels are required, although input, output, supply, and common-mode limits must still be checked independently.
For PCB design, keep input and feedback traces short, use a solid ground reference, place compensation or decoupling components according to the manufacturer’s application guidance, and verify stability with the selected gain and load. For replacements, the LT1215 is a dual-package family member but is not a pin-compatible substitute for this 16-pin quad device; package and pin count must be checked before any redesign.

典型應用
LT1216CS 適用於 6 應用s: Precision Instrumentation Front Ends, ADC Signal Conditioning, Active Analog Filters, Communication Interface Circuits, Audio Signal Conditioning, Data Converter Output Buffering.
Precision Instrumentation Front Ends
The LT1216CS fits precision instrumentation front ends because it combines four general-purpose amplifier channels with a 23 MHz typical gain-bandwidth product and 50 V/µs typical slew rate. The quad package can consolidate multiple signal-conditioning stages while preserving wider bandwidth than a purely low-frequency precision amplifier. Designers should verify offset voltage, bias current, common-mode range, and output swing from the manufacturer datasheet, then choose resistor values and compensation for the required gain. The fast settling data—250 ns to 0.01% after a 2 V step—provides a useful starting point for measurement paths, although sensor drive, ADC acquisition, and cable capacitance determine final performance.
推薦
ADC Signal Conditioning
The LT1216CS can condition signals before an ADC when the design needs faster settling than a conventional precision op amp and four amplifier channels are useful. Its 23 MHz typical gain-bandwidth product and 50 V/µs slew rate support gains and bandwidths that must preserve small-signal detail during conversion. The amplifier must still be checked against the ADC input range, sampling aperture, source impedance, and required acquisition time. In a practical implementation, place the amplifier close to the ADC, use short feedback paths, and verify settling with the actual channel gain and capacitive load.
推薦
Active Analog Filters
The LT1216CS is suitable for active filtering where a 23 MHz gain-bandwidth product and 50 V/µs slew rate provide useful headroom for precision and wideband filter stages. Its four channels can implement multiple sections or support buffer and gain stages without requiring four separate amplifier packages. Component tolerances, op-amp noise, output loading, and loop stability determine the achievable filter response, so simulation should include the complete network rather than relying only on nominal gain-bandwidth product. The manufacturer’s settling figures are useful when designing filters that must recover quickly after input steps.
推薦
Communication Interface Circuits
The LT1216CS can serve as a general-purpose amplifier in communication interface circuits that require a low-noise precision signal path and more bandwidth than a slow comparator-based solution. The 23 MHz gain-bandwidth product and 50 V/µs slew rate are useful for buffering, gain shaping, and line-driver support stages, subject to output-current and load limits not fully specified in the supplied excerpts. PCB layout should minimize trace capacitance and feedback-loop area, and the amplifier’s common-mode range must remain valid across the full signal excursion.
推薦
Audio Signal Conditioning
The LT1216CS can be evaluated for audio signal-conditioning and low-frequency active-filter stages where speed and DC precision are both useful. Its 50 V/µs typical slew rate provides ample response for many audio bandwidth signals, while the 23 MHz typical gain-bandwidth product is well above the audible band. Actual audio performance also depends on noise density, input-voltage noise, output drive, load impedance, and power-supply configuration, which are not all included in the supplied search snippets. Confirm those parameters in the manufacturer datasheet before using it as a direct replacement for a specialized audio amplifier.
推薦
Data Converter Output Buffering
The LT1216CS may be useful as an output buffer or gain stage for DAC and data-converter systems where the source device requires isolation, level translation, or a controlled drive impedance. The quad format allows several buffers to share one package, and the 23 MHz gain-bandwidth product can provide margin above converter bandwidth. The design must confirm output swing, capacitive-load stability, supply headroom, and settling into the next device. Short traces, local decoupling, and a defined return-current path are especially important when the amplifier sits close to high-speed converter pins.

- Fast settling for signal conditioning (對比LT1216IS)
設計說明
Keep the LT1216CS input and feedback traces short, especially when the 23 MHz typical gain-bandwidth product is being used near the upper useful frequency range. Route the feedback return directly to the amplifier output-side ground reference and avoid sharing high-current return paths with sensitive inputs. Because the supplied data does not include complete input-noise, bias-current, and common-mode specifications, simulate the actual source impedance and verify the datasheet limits before production release.
The LT1216CS is specified for supplies greater than 2.5 V and less than 36 V total, but the exact supply-current and transient limits are not present in the supplied excerpts. Place local input and output decoupling close to the device, provide a low-impedance ground return, and verify startup and shutdown behavior in the actual circuit. Do not treat the supply-voltage statement alone as permission to operate near 36 V without checking transient margin and package dissipation limits.
The LT1215 is a dual amplifier while the LT1216CS is a quad amplifier. Their shared family headline specifications of 23 MHz gain-bandwidth product and 50 V/µs slew rate do not make the parts pin-compatible. Before a redesign, map every LT1216CS pin, confirm the 16-pin SOIC footprint, check whether rail-to-rail behavior is required, and compare offset voltage, bias current, noise, output current, and common-mode limits rather than matching only bandwidth.
Use a compact analog layout around the amplifier. Place input and feedback components close to their associated pins, keep the high-speed path away from switching nodes and digital return currents, and provide an uninterrupted ground plane. If driving ADC, DAC, or cable inputs, include the intended load and capacitance during settling tests. The manufacturer datasheet should be the source for any recommended compensation or decoupling values because those values are not included in the supplied search snippets.
