AD9240ASRL 概述
An ADC is a data-acquisition IC that samples an analog voltage and converts it into a digital code for processing, storage, or transmission. The AD9240 belongs to the converter hierarchy of data converter, ADC, monolithic ADC, and semiconductor. Its 10 MSPS conversion rate supports sampled measurement of imaging, communications, medical, and data-acquisition signals, while 14-bit resolution represents 16,384 distinct output codes.
The verified product information identifies a low-noise sample-and-hold amplifier, a flexible differential input structure, and support for single-ended or differential inputs with varying input spans. A single +5 V supply simplifies system power design, and the listed 285 mW low power dissipation is suitable for power-conscious acquisition systems. Integral nonlinearity error is specified at 2.5 LSB, while differential nonlinearity error is specified at 0.6 LSB.
The AD9240 uses a CMOS process and a pipelined architecture to combine resolution and throughput without the power consumption associated with hybrid converters. Its parallel digital output requires a correctly timed receiving device, such as an FPGA, DSP, microcontroller, or logic interface, while analog front-end conditioning remains important when the source impedance, source noise, and input bandwidth are not already suitable for direct ADC connection.
Typical uses include digital imaging systems, communications equipment, medical instrumentation, and general-purpose data acquisition. In an imaging design, the converter samples video-derived analog signals; in communications, it digitizes modulated waveforms; in medical equipment, it supports sensor digitization; and in laboratory systems, it captures repetitive or multiplexed inputs when the source circuit and sampling architecture are appropriate.
The principal design consideration is preserving the converter's specified input range, bandwidth, and sampling performance through the analog network. Designers should follow the manufacturer datasheet for input impedance, voltage limits, timing, reference requirements, digital interface details, and decoupling. Because the AD9240 is marked LAST TIME BUY, new production designs should confirm lifecycle availability and consider an approved migration path before committing.
This product page consolidates verified manufacturer specifications, distributor availability information, lifecycle status, application guidance, and explicitly qualified replacement information. It does not treat every similar ADC as a drop-in substitute; pin compatibility, package identity, interface behavior, and critical timing must be checked independently before redesign.

典型应用
AD9240ASRL 适用于 6 应用s: Digital Imaging Systems, Communications Signal Acquisition, Medical Instrumentation, General Data Acquisition, Industrial Control and Monitoring, Test and Measurement Equipment.
Digital Imaging Systems
The AD9240ASRL fits imaging systems that need to convert analog video-derived or image-sensor signals into 14-bit digital words at up to 10 MSPS. Its single +5 V supply and flexible single-ended or differential input structure let the analog front end accommodate different sensor spans when the external conditioning network is designed for the required range. The parallel output can feed an FPGA or other digital capture device, but timing margin and voltage compatibility must be verified. A 10 MSPS rate is appropriate for systems whose signal bandwidth and sampling plan do not require a faster converter. The main design concern is preserving accuracy from sensor output through the ADC input network.
推荐
Communications Signal Acquisition
For communications equipment, AD9240ASRL can digitize a conditioned analog waveform at 10 MSPS and 14-bit resolution. The converter's flexible input arrangement supports single-ended or differential signal paths, which is useful when the receiver front end uses a balanced mixer, attenuator, or filter. The 10 MSPS sampling rate provides an upper conversion-rate ceiling, not automatic RF bandwidth performance; anti-alias filtering, gain control, clock jitter, and settling time remain critical. A parallel interface is appropriate for FPGA-based demodulation, modulation, or test logic, provided the receiver uses compatible voltage levels and verified timing.
推荐
Medical Instrumentation
AD9240ASRL can serve as the digitization stage in medical instrumentation when a sensor or analog front end produces a signal within the converter's verified input conditions. The 14-bit code width and 10 MSPS rate provide a defined starting point for instrumentation design, while the differential-capable input structure can help reject common-mode noise when implemented correctly. The application still requires separate validation of accuracy, noise, isolation, safety, environmental range, and regulatory compliance; the supplied data does not confirm medical certification. Use the manufacturer datasheet for electrical limits and reference requirements, and isolate the analog and digital sections according to the system risk assessment.
推荐
General Data Acquisition
The AD9240ASRL is appropriate for laboratory and embedded data-acquisition systems that sample one analog channel at 10 MSPS and require a parallel 14-bit interface. It can support acquisition of transient, vibration, control, or instrumentation signals after the source is buffered and filtered to meet the ADC input requirements. The single +5 V supply simplifies power planning, while the parallel output requires enough board space and digital timing verification. Because the converter is marked LAST TIME BUY, existing data-acquisition designs may benefit from supply continuity, but new platforms should compare lifecycle alternatives before committing to a long production run.
推荐
Industrial Control and Monitoring
AD9240ASRL can digitize conditioned analog signals in industrial monitoring equipment when a 14-bit, 10 MSPS parallel ADC is sufficient. The device may be used for process variables, actuator feedback, vibration monitoring, or other sampled control signals after appropriate isolation, protection, filtering, and level shifting. Its operating-temperature snippet of -40 C to +85 C is relevant for equipment planning, but the complete electrical limits and environmental qualification must be taken from the official datasheet. Industrial deployments should also address supply-chain risk because the product is LAST TIME BUY and should verify long-term availability before design freeze.
推荐
Test and Measurement Equipment
The AD9240ASRL can be used in test and measurement products when a compact, parallel-output ADC is needed for capturing analog waveforms or sensor outputs. The 14-bit resolution supports detailed digital representation, and the 10 MSPS rate is useful for repetitive measurements, communication tests, and automated production equipment. The receiving FPGA must capture the parallel bus without setup-and-hold violations, while the analog front end must provide the correct span, bandwidth, and source impedance. A programmable signal source such as an AD9959 can be useful in a broader test architecture, but its relationship is functional rather than a drop-in companion.

设计说明
The verified AD9240ASRL specification identifies a single +5 V supply and 285 mW power dissipation. Design the supply rail with local decoupling and verify the regulator's noise, ripple, startup, and load-current behavior against the manufacturer datasheet. Do not infer the required capacitor values from the power figure alone; input, reference, and bypass recommendations must come from the official application and pin guidance. For a mixed-signal board, keep switching supplies and high-current digital paths physically separated from the ADC analog input and reference network.
Place the ADC input, reference, and decoupling network close to the device and keep the parallel output routing short and controlled. Because the AD9240 uses a pipelined parallel conversion path, the receiver must satisfy the specified output timing and voltage levels; routing resistance, capacitance, and clock/data skew can affect capture reliability. Use a continuous ground reference, avoid splitting analog and return currents unnecessarily, and follow the manufacturer's recommended land pattern and pin orientation. The supplied data does not include a complete pin table, so do not build a board from the package name alone.
The converter's 10 MSPS rate does not remove the need for careful analog bandwidth and anti-alias design. Select input attenuation, gain, filtering, and termination so the signal remains within the ADC's verified input span while preserving settling and bandwidth requirements. Evaluate source impedance and sampling kickback at the input node, and use a driver or buffer when the source cannot meet those conditions. For communications or instrumentation, measure clock jitter and analog noise at the interface rather than relying only on nominal converter specifications.
Do not treat AD9240ASRL, AD9240ASZRL, and AD9240ASZ as interchangeable without checking the exact Analog Devices part description, package drawing, pinout, temperature range, lifecycle status, and timing tables. The supplied cross-reference pages identify related parts but do not prove pin compatibility. Similarly, do not assume that the distributor's “ships today” statement guarantees future availability because the manufacturer marks AD9240ASRL LAST TIME BUY. Record the approved alternate, validation results, and approved source before releasing a replacement.
合规信息
The supplied verified product and distributor snippets do not state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. Compliance must be confirmed using current Analog Devices documentation and applicable sourcing records.
