ADC0804S040TS/C1 概要
An analog-to-digital converter (ADC) is a mixed-signal integrated circuit that samples continuous-time analog voltages and quantizes them into discrete digital codes. Pipeline ADCs like the ADC0804S040TS use a switched-capacitor architecture with multiple gain stages and a flash backend, achieving a balance between sampling speed, resolution, and power consumption. In the broader system hierarchy, an 8-bit ADC belongs to the data-converter family, which sits under signal-chain ICs and ultimately power-management and mixed-signal IC categories of semiconductors.
Key features of this device include 8-bit resolution, a 40 MSPS maximum sampling rate, single-channel input, parallel output interface, and low power consumption typical of the family. The 28-SSOP package offers a compact footprint suitable for high-density PCB layouts in video capture cards, LCD projection systems, and digital oscilloscope front ends. The architecture provides excellent linearity at video-grade sample rates, making it suitable for digitizing standard-definition video signals.
Typical applications include professional video digitizing equipment, surveillance and security camera systems, set-top box video processing, medical imaging front ends, and general-purpose high-speed data acquisition systems. The wide sampling-rate headroom (up to 40 MSPS) oversamples standard video bandwidths, easing analog anti-alias filter design.
When designing with this part, pay attention to analog input bandwidth and clock-jitter budgets, as jitter directly affects SNR. Use a low-jitter clock source and provide adequate decoupling on AVDD/DVDD rails. The commercial-grade temperature range (0C to +70C) makes it suitable for indoor equipment but not for automotive or extended-industrial deployments.

主な用途
ADC0804S040TS/C1 の用途: 6 件s: Professional Video Digitizing, Set-Top Box Video Processing, Surveillance and Security Cameras, Medical Imaging Front End, General-Purpose High-Speed Data Acquisition, LCD Projection Systems.
Professional Video Digitizing
The ADC0804S040TS/C1 fits professional video digitizing because its 40 MSPS sample rate exceeds the Nyquist requirement for standard-definition and many enhanced-definition video formats, while its 8-bit resolution matches broadcast-quality luminance capture. The TTL/CMOS-compatible parallel output enables direct connection to video encoders, frame grabbers, and FPGA-based processing pipelines. Designers can pair the part with a low-jitter clock source and a 4th-order anti-alias filter to achieve clean video SNR.
おすすめ
Set-Top Box Video Processing
In set-top box video pipelines, the ADC0804S040TS/C1 digitizes composite or component video inputs at sample rates up to 40 MSPS, providing sufficient oversampling for digital comb-filter decoding and MPEG encoding stages. Its single-channel input matches the typical front-end architecture where a single video DAC feeds the digitizer, and its parallel interface streams samples directly into the host SoC. Low power consumption makes it well-suited to thermally constrained consumer enclosures.
おすすめ
Surveillance and Security Cameras
The ADC0804S040TS/C1 suits surveillance and security camera designs where 8-bit resolution and 40 MSPS sample rate are sufficient for digital video recording, motion detection, and frame-store processing. The SSOP-28 package allows compact PCB layouts in miniature camera enclosures, and the commercial 0C to +70C temperature range covers indoor and sheltered-outdoor deployments. Designers typically pair it with image preprocessing ASICs or low-cost FPGA controllers.
おすすめ
Medical Imaging Front End
In ultrasound and other medical imaging front ends, the ADC0804S040TS/C1 provides cost-effective digitization of analog pre-processed signals at sample rates up to 40 MSPS. While 8-bit resolution limits dynamic range, it is well suited to B-mode envelope detection and beam-formed signal paths where subsequent digital processing refines the image. The low-jitter clock requirement aligns with the deterministic sampling needs of medical instrumentation.
おすすめ
General-Purpose High-Speed Data Acquisition
The ADC0804S040TS/C1 serves well in general-purpose data acquisition cards for industrial test, measurement, and instrumentation, where 8-bit resolution and 40 MSPS bandwidth cover many vibration, sonar, and IF-strip digitizing applications. Its parallel output simplifies timing closure in FPGA-based acquisition systems, and the standard SSOP-28 footprint eases PCB layout and rework. Engineers can use it for bench-top instruments, factory test rigs, and embedded control monitoring.
おすすめ
LCD Projection Systems
LCD projection systems use the ADC0804S040TS/C1 to digitize incoming analog video (VGA, composite, component) at up to 40 MSPS, providing the digital stream required by the scaler/format-converter ASIC. The 8-bit resolution is adequate for consumer-grade projection image quality, while the parallel output interfaces directly with image-processing pipelines. The compact SSOP-28 package supports the dense mainboards found inside projector light engines.

主な差別化要因
- 40 MSPS sample rate with headroom for standard-definition video （vs ADC0803S030TS/C1 (30 MSPS))
- Optimized for moderate-power, video-grade applications （vs Higher-resolution ADCs (e.g., AD7674ACPZRL 14-bit))
- TTL/CMOS-compatible parallel output （vs Serial-output ADCs in similar resolution class)
設計ノート
Separate analog and digital grounds with a single-point connection near the AGND/DGND pins to avoid digital switching noise coupling into the analog input path. Place the input coupling capacitor and anti-alias filter components as close as possible to the AIN pin, and keep the analog input trace short and guarded with ground pour. The clock trace should be routed away from the analog input to minimize jitter and crosstalk.
Do not exceed the absolute maximum analog input range referenced to VRT and VRB - the device will saturate and may degrade SNR if overdriven. Ensure the external clock source has low jitter (<5 ps RMS) to preserve SNR at the 40 MSPS maximum rate. The reference voltages VRT and VRB must be stable and well decoupled; any noise on these pins directly couples into the conversion result.
Estimated: at 40 MSPS, the ADC0804S040TS/C1 consumes roughly 80-120 mW from AVDD and DVDD combined (input voltage dependent). Provide separate local decoupling on AVDD and DVDD - a 10 uF bulk plus a 100 nF ceramic bypass near each supply pin - to suppress switching transients. If AVDD and DVDD are tied together, insert a ferrite bead to isolate analog and digital return currents.
