LT1216CN - 23MHz Quad Precision Op Amp | Analog Devices
MPN: LT1216CN ✓ Hoạt độngLT1216CN Tóm tắt
An operational amplifier is an active analog building block that amplifies the voltage difference between its inverting and non-inverting inputs. The LT1216 belongs to the broader hierarchy of amplifier IC, instrumentation amplifier, and operational amplifier products used in precision signal chains. Its precision characteristics reduce the need for external trimming in many systems, while its high bandwidth and slew rate support accurate response to rapidly changing signals.
The verified product information identifies the LT1216 as a four-circuit, bipolar, PDIP-14 precision amplifier. The family is specified at 23 MHz gain-bandwidth product and 50 V/us slew rate. The single-supply capability is useful in systems where the signal and supply rails must be referenced close to ground. The package provides four amplifier channels in one component, allowing multiple signal paths to share a common footprint and simplifying board-level layout.
The LT1216 family is based on the LT1215 dual amplifier and extends the same precision amplifier architecture to four channels. The combination of high gain-bandwidth product, high slew rate, and DC precision is useful when a design must preserve small-signal accuracy while also handling waveforms with meaningful frequency content. Applications include sensor signal conditioning, active filters, low-level current-to-voltage conversion, data acquisition front ends, and general-purpose analog control.
Because the LT1216CN is a monolithic four-channel device, decoupling and grounding remain important design considerations. Each supply rail should be bypassed close to the device with suitable local capacitance, and sensitive analog signals should be routed away from noisy switching nodes. The 14-pin PDIP package also requires adequate spacing and appropriate lead formation during assembly, making it more convenient for through-hole prototypes than for space-constrained surface-mount products.
This product page synthesizes the verified manufacturer description, distributor identification, package information, and available comparison references for engineers evaluating the LT1216CN. Because the supplied web data does not include complete electrical tables, pricing values, or a confirmed pin-by-pin diagram, unavailable technical fields are explicitly marked rather than inferred.

Ứng dụng tiêu biểu
LT1216CN phù hợp cho 6 Áp dụngs: Precision Sensor Signal Conditioning, Active Filtering, Data Acquisition Front End, Low-Level Current-to-Voltage Conversion, Industrial Control Signal Conditioning, General-Purpose Analog Buffering.
Precision Sensor Signal Conditioning
The LT1216CN is suitable for conditioning low-level sensor signals where four channels can share one package. The LT1216 family's 23 MHz gain-bandwidth product provides useful bandwidth for signals that must retain amplitude and phase accuracy, while 50 V/us slew rate supports faster transitions than a conventional low-speed precision amplifier. Each channel can amplify a sensor output before filtering, level shifting, or conversion. The single-supply architecture is attractive when the signal is referenced near ground, although engineers should verify the exact input common-mode range and output swing from the manufacturer datasheet before biasing the circuit.
Được đề xuất
Active Filtering
The LT1216CN can implement active filters and frequency-shaping stages in analog signal chains. Its 23 MHz gain-bandwidth product provides useful loop bandwidth for precision filter topologies, and the 50 V/us slew rate helps preserve large-signal behavior when the filter must process waveforms beyond very low frequencies. Four channels allow linked stages or multiple filter sections to be implemented in one 14-pin PDIP package. Component tolerance, stability, and achievable noise performance should be checked against the target gain and bandwidth using the full Analog Devices datasheet and standard stability analysis.
Được đề xuất
Data Acquisition Front End
The LT1216CN is appropriate for buffering and amplification ahead of data-conversion or sampling circuits. The combination of 23 MHz gain-bandwidth product and 50 V/us slew rate supports wide-band signal conditioning while the quad configuration reduces the number of separate amplifier packages required on the board. Engineers can assign channels to separate inputs, differential stages, or gain blocks. Layout should keep input routing short, provide local supply bypass, and maintain a clean ground reference so that high-speed behavior does not degrade measurement accuracy.
Được đề xuất
Low-Level Current-to-Voltage Conversion
The LT1216CN can support precision transimpedance and current-to-voltage conversion stages in instrumentation systems. Its high gain-bandwidth product and high slew rate provide the dynamic performance needed when the amplifier must operate at moderate closed-loop gains while handling small input currents and control-loop compensation requirements. Multiple channels allow monitoring or converting several low-level signals in parallel. The exact input bias current, offset voltage, noise, common-mode limits, and stability method must be confirmed from the complete datasheet because those parameters are not included in the supplied verified excerpts.
Được đề xuất
Industrial Control Signal Conditioning
The LT1216CN can condition industrial sensor, control, and feedback signals where several amplifier channels are required on a through-hole board. The quad bipolar design provides a practical way to amplify control-loop signals, scale analog inputs, or buffer outputs while retaining the LT1216 family's precision and speed. The 14-pin PDIP format is particularly useful for prototypes, legacy equipment, and industrial control boards with through-hole assembly. Designers should verify supply tolerances, output load capability, and thermal limits for the intended industrial environment using the manufacturer documentation.
Được đề xuất
General-Purpose Analog Buffering
The LT1216CN is suitable for general-purpose buffering and gain stages where four independent channels provide more integration than a dual amplifier. The 23 MHz gain-bandwidth product makes the device useful beyond simple DC voltage-following, while the 50 V/us slew rate supports faster signal transitions. Designers can use the channels for input buffers, output drivers, fixed-gain stages, and mixed signal conditioning. The appropriate supply voltage and external resistor or capacitor network must be selected from the full datasheet, and each power rail should be adequately decoupled near the package.

Ghi chú thiết kế
The supplied excerpts do not provide the LT1216 supply-voltage limits, so the first design step should be to confirm the allowed input voltage and output swing in the Analog Devices datasheet. Place local supply-bypass capacitors close to the device supply pins and return their ground connections through a low-impedance path. Because the amplifier is specified for high bandwidth and slew rate, inadequate bypassing can introduce supply ripple coupling, instability, or unexpected channel-to-channel behavior. Confirm capacitor voltage rating and ESR requirements against the manufacturer recommendations.
Treat the four channels as separate high-performance analog paths even though they share one package. Route sensitive input and feedback nets away from supply traces, digital switching nodes, and the underside of the through-hole package where appropriate. Keep feedback components close to their corresponding amplifier pins and minimize parasitic capacitance in high-gain nodes. The PDIP format provides ample physical spacing, but careless long traces or shared ground paths can still degrade the precision and dynamic performance expected from the LT1216 family.
Do not substitute a generic quad operational amplifier solely because it has the same 14-pin PDIP footprint. A valid replacement must match pin assignments, supply range, input common-mode range, output swing, offset, bias current, noise, gain-bandwidth product, slew rate, and stability requirements. In particular, single-supply operation does not imply that the input or output can reach either supply rail. Use the complete LT1216 datasheet and compare the candidate device under the actual gain, load, and common-mode conditions.
Thông tin tuân thủ
The supplied verified data does not explicitly state compliance status for LT1216CN. A related LT1216CN#PBF ordering designation is listed by Mouser, but its lead-free designation should not be transferred automatically to LT1216CN. This is an analog operational amplifier and is not an automotive-qualified device.
