An Analog-to-Digital Converter (ADC) is a mixed-signal integrated circuit that samples a continuous-time, continuous-amplitude analog waveform and quantises each sample into a discrete digital code. The 8-bit resolution part of the taxonomy hierarchy is: video-flash ADC -> successive-approximation / pipelined video ADC -> ADC -> data converter -> mixed-signal IC -> semiconductor. 8-bit, high-speed ADCs of this class sit between precision 12-/14-/16-bit SAR ADCs (slow, high-accuracy) and ultra-high-speed 6-/8-bit flash ADCs (very fast, lower accuracy). The 30 MSPS sample rate matches the pixel clock of standard-definition (CCIR 601 / NTSC) digital video systems.
The ADC0804S030TS/C1:1 features an on-chip reference, a sample-and-hold amplifier, and a digital error-correction pipeline that removes the need for external trimming. The analog input range is typically 1 Vp-p centred on a mid-scale reference, and the digital outputs are 3-state CMOS-compatible, allowing direct connection to ASICs, FPGAs, or microprocessors without external glue logic. The pipelined architecture delivers low latency between sample and output, which is critical for video frame-grabber and time-correlated imaging applications.
When designing with this converter, pay particular attention to PCB layout: the analog and digital grounds should be separated and joined only at the AGND/DGND pins of the package. Use a low-impedance analog input trace terminated to match the source impedance, and bypass each supply pin with a 100 nF ceramic and a 10 µF tantalum bulk capacitor placed within 5 mm of the device. The 28-SSOP footprint is footprint-compatible with the faster ADC0804S040TS (40 MSPS) and ADC0804S050TS (50 MSPS) variants of the same family, so the same PCB layout supports the entire 30/40/50 MSPS range.
Typical applications include professional video frame grabbers, digital broadcast studio equipment, set-top box video decoders, medical imaging front-ends, and high-speed CCD/CIS sensor digitisation.

典型應用
ADC0804S030TS/C1:1 適用於 6 應用s: Professional SD Video Frame Grabber, Digital Broadcast Studio Equipment, Set-Top Box Video Decoder, Medical Imaging Front-End (Ultrasound / Endoscope), Industrial CCD / CIS Line-Scan Digitisation, Oscilloscope / Test Instrumentation Front End.
Professional SD Video Frame Grabber
Digitises CCIR 601 / NTSC / PAL composite or component video at 27 MHz pixel clock into a frame buffer for editing and broadcast. The ADC0804S030TS/C1:1's 30 MSPS sample rate comfortably exceeds the 27 MSYS Nyquist requirement, while the single-ended analog input and parallel 8-bit output interface directly to the FPGA's SDRAM controller. Pipelined architecture keeps group delay constant and short, which is critical for time-correct frame reconstruction without per-pixel latency jitter. The on-chip reference eliminates external drift components and reduces BOM cost.
推薦
Digital Broadcast Studio Equipment
Captures SDI / SD video signals in mixing desks, character generators, and broadcast graphics engines at full 8-bit resolution. The device's 5 V analog and digital supplies match the existing broadcast infrastructure that has used 5 V ADCs for two decades. Single-channel sampling at 30 MSPS allows per-pixel digitisation at standard SD frame rates without multiplexing artefacts. Power consumption of roughly 90 mW is acceptable for rack-mount chassis with forced-air cooling common in studio installations.
推薦
Set-Top Box Video Decoder
Provides the analog front-end digitisation for legacy video inputs in hybrid set-top boxes. The 28-SSOP package is small enough for the dense set-top box motherboard, and the commercial 0 °C to +70 °C operating range matches indoor consumer thermal envelopes. The 8-bit parallel bus can interface directly to a video decoder SoC or a low-cost FPGA that performs additional de-interlacing and scaling. This drops neatly in front of low-cost H.264/H.265 encoders.
推薦
Medical Imaging Front-End (Ultrasound / Endoscope)
Digitises analog outputs from ultrasound transducers or CCD-based endoscopic cameras at high speed into a digital image processing chain. The pipelined 30 MSPS throughput captures each transducer channel at clinical frame rates, and the 8-bit resolution is sufficient for tissue contrast visualisation after post-processing gain mapping. The SSOP-28 package eases hand-routed multi-channel board layouts where many ADCs sit parallel. Commercial operating range is acceptable for ambient-controlled examination rooms.
推薦
Industrial CCD / CIS Line-Scan Digitisation
Captures single-line outputs from industrial line-scan CCD or contact image sensor arrays used in document scanners, textile inspection, and machine-vision sorting lines. The 30 MSPS sample rate supports high line-scan rates for fast conveyor throughput, and the parallel 8-bit digital output synchronises directly to FPGA line buffers. The 5 V analog input range simplifies interface to traditional CCD analog front-ends that include correlated double sampling. Commercial screening suffices for factory-floor environments.
推薦
Oscilloscope / Test Instrumentation Front End
Forms the analog input stage of low-cost digital oscilloscopes, logic analyser pods, and data-acquisition modules that need 30 MSPS of bandwidth into 8-bit resolution. The internal sample-and-hold and 3-state output bus reduce external component count for compact bench instruments, while pipelined latency remains predictable for time-base markers. The 28-SSOP format fits into multi-channel sweep boards alongside op-amp input stages. Parallel interface allows straightforward DMA capture to a host processor.

設計說明
Estimated: Separate analog and digital ground planes and join them only at the AGND and DGND pins of the ADC. Place a 100 nF ceramic bypass capacitor within 5 mm of each AVDD/DVDD pin, plus a single 10 µF tantalum or polymer bulk capacitor on each rail. Route the analog input trace with 50 Ω controlled impedance, kept short and away from digital outputs D0-D7 to avoid coupling of digital switching noise into the analog front-end.
Do not exceed the 5 V absolute maximum supply rating; transient spikes from inductance in the power leads can damage the input ESD structure. The analog input common-mode voltage must sit within 1 V of AVDD/2 - DC offsets near either rail will exceed the input range and saturate the converter. Always drive the CLK pin with a clean low-jitter CMOS source; sample jitter directly degrades aperture SNR.
Recommended: Place the oscillator or clock buffer within 25 mm of the CLK pin to minimise trace inductance. Keep the parallel output bus D0-D7 matched in length (within 2 mm) and terminate each line with a series 33 Ω resistor close to the ADC if the FPGA receiver is more than 50 mm away. Shield the analog input trace with a guard ground track that is stitched with vias to the analog ground plane every 5 mm.
