AD9240ASZRL - 14-Bit 10 MSPS ADC | Analog Devices
MPN： AD9240ASZRL ⚠ 最後購買機會AD9240ASZRL 概覽
An ADC is an analog-to-digital converter, a semiconductor in the data-conversion hierarchy that samples a continuous analog voltage and produces a corresponding digital code. The AD9240 belongs to the pipelined ADC class, whose multistage architecture supports high conversion rates while providing separate resolution and speed options for instrumentation, communications, and industrial control.
The AD9240 integrates a high-performance, low-noise sample-and-hold amplifier with programmable voltage-reference circuitry. According to the Analog Devices AD9240 product page, an external reference may instead be selected when an application requires different DC-accuracy or temperature-drift characteristics. Its stated integral nonlinearity is 2.5 LSB and differential nonlinearity is 0.6 LSB.
The device uses a low-cost, high-speed CMOS process and a novel architecture intended to achieve the resolution and speed associated with earlier hybrid implementations at lower power and cost. Its 14-bit parallel data interface provides direct connection to FPGA, CPLD, DSP, or other digital acquisition logic without requiring a serial data link.
Typical uses include industrial measurement, communications receivers, waveform acquisition, laboratory instrumentation, and embedded control. The 10 MSPS rate provides useful bandwidth for sampled signals, while the 0.36 LSB input-referred noise supports precision in the converter's native 14-bit domain.
Designers should treat the analog input as a high-speed signal and use a controlled reference, suitable bypass decoupling, and short, carefully routed parallel traces. The MQFP package is not an exposed-pad design, so thermal performance depends on its specified package characteristics and PCB copper rather than an exposed thermal slug.
This product page consolidates verified manufacturer specifications, sourcing information, lifecycle status, and drop-in replacement analysis. It also distinguishes verified same-package alternatives from unsupported cross-package substitutes, helping engineers plan AD9240ASZRL replacements without changing the PCB footprint.

典型應用
AD9240ASZRL 適用於 6 應用s: Industrial Process Measurement, Communications Receiver, Waveform Acquisition, Medical Signal Monitoring, Embedded Control and Monitoring, Portable Test Equipment.
Industrial Process Measurement
The AD9240ASZRL fits industrial process-acquisition front ends that sample sensor-derived voltages at up to 10 MSPS while retaining a 14-bit digital result. Its 0.36 LSB input-referred noise and verified -40 C to +85 C operating range support precision measurement across changing conditions. Place conditioning amplification and anti-alias filtering ahead of the converter, then route the parallel output to an FPGA or DSP. The single +5 V rail and 285 mW dissipation simplify system power planning, although LAST TIME BUY availability must be secured.
推薦
Communications Receiver
AD9240ASZRL can digitize receiver waveforms when the required sample rate is no greater than the converter's verified 10 MSPS capability. Its monolithic 14-bit architecture converts the conditioned analog channel into parallel digital words suitable for FPGA-based demodulation or filtering. The 285 mW figure makes it practical for compact receiver subsystems, but engineers must budget analog and digital gain, clock timing, reference accuracy, and the unused high-rate transition band. The design should use controlled return paths and matched digital timing.
推薦
Waveform Acquisition
The AD9240ASZRL supports laboratory and service-test waveform acquisition where 14-bit resolution and a 10 MSPS ceiling are sufficient. Its integrated low-noise sample-and-hold amplifier reduces the number of discrete front-end stages, while the parallel output simplifies capture into logic. Engineers should define full-scale input, sampling clock jitter, input bandwidth, and memory depth before routing the 14-bit bus. Because the package is a 44-MQFP rather than an exposed-pad design, conventional SMD assembly and package-compatible layout practices apply.
推薦
Medical Signal Monitoring
AD9240ASZRL may be evaluated for low-bandwidth biomedical monitoring when the signal path meets its 14-bit, 10 MSPS limits. The 0.36 LSB input-referred noise provides a useful starting point for low-frequency physiological signals, while integrated sampling circuitry simplifies the analog front end. However, the supplied data does not confirm medical-device qualification, so it must not be treated as an AEC-Q100 or clinical-approved component. Protection, patient isolation, diagnostics, and regulatory validation remain system-level responsibilities.
推薦
Embedded Control and Monitoring
The AD9240ASZRL can provide a high-resolution feedback channel in embedded monitoring systems where motor, machine, or power signals require waveform observation. Its 10 MSPS rate captures fast transients better than a slow control-loop ADC, while the 14-bit parallel result provides detailed data for fault analysis. Connect the output to an FPGA or DSP for filtering, capture, and event classification. Validate voltage levels, clock domain crossings, and isolation before attaching the converter directly to a controller.
推薦
Portable Test Equipment
AD9240ASZRL is relevant to portable or bench-top test equipment that requires moderate acquisition bandwidth without a high-power converter. The single +5 V supply and verified 285 mW dissipation support compact analog sections, while the 14-bit parallel output avoids demanding high-speed serial deserialization. Trade-offs include the relatively large 44-MQFP footprint and parallel-routing effort. A portable design should account for display or control processing separately, use local decoupling, and verify battery-power conversion efficiency upstream of the ADC.

與替代品比較
| 參數 | 本產品 | AD9240AS | AD9240ASZ | AD9280ARSZ |
|---|---|---|---|---|
| Brand | Analog Devices | Analog Devices | Analog Devices | Analog Devices |
| Resolution | 14 bits | 14 bits | 14 bits | 8 bits |
| Sampling Rate | 10 MSPS | 10 MSPS | 10 MSPS | 32 MSPS |

主要差異化特點
- Higher native resolution than AD9280ARSZ (對比AD9280ARSZ)
- Lower maximum sampling rate than AD9280ARSZ (對比AD9280ARSZ)
- Lower verified power dissipation (對比AD9280ARSZ)
設計說明
Route the 14-bit parallel output as a compact, continuously referenced bus to the FPGA, CPLD, or DSP. Match trace lengths where practical, provide a nearby ground reference plane, and isolate the output path from high-current switching nodes. Confirm data setup and hold timing at the receiving device because 10 MSPS operation leaves limited tolerance for routing delay.
Decouple the +5 V supply at the converter using the capacitance and placement specified by Analog Devices. Estimated converter dissipation is 285 mW because that value is stated directly in the verified data; no additional calculation is required. Validate the upstream regulator's startup, ripple, and transient response because supply disturbance can appear in the 0.36 LSB input-referred-noise performance.
Do not substitute AD9243ASZRL or another higher-speed ADC solely from its family name. The verified cross-reference results do not prove a 44-MQFP pin-compatible footprint, identical voltage reference, or identical timing. Obtain each candidate's official data sheet and compare pin assignments, output coding, clock polarity, supply sequencing, and digital timing before approving a replacement.
合規資訊
The supplied verified data does not state RoHS, REACH, lead-free, halogen-free, or conflict-minerals compliance. AEC-Q100 is not applicable based on the supplied general-purpose product information, but no automotive qualification claim is made.
