ADC0804S050TS/C1:1 Présentation
An analog-to-digital converter (ADC) is a mixed-signal integrated circuit that samples a continuous-time analog voltage and quantizes it into a discrete digital code; flash, pipelined, and successive-approximation architectures dominate the high-speed 8-bit segment. The ADC0804S family sits at the intersection of the video ADC and high-speed data-acquisition hierarchies, optimized for low-power operation and direct connection to digital video processors, FPGAs, or DSPs without external buffering.
Key features include a single analog input channel, 8-bit resolution, up to 50 MSPS sample rate, TTL/CMOS-compatible digital inputs and outputs with built-in latches, low-power CMOS architecture, and an operating temperature range of 0C to +70C commercial grade. The on-chip sample-and-hold and reference ladder simplify external bill-of-materials, while the SSOP-28 footprint provides robust thermal performance and reliable surface-mount assembly.
The architecture uses a pipelined-flash topology with internal bandgap reference and onboard clock conditioning, accepting a low-level sine-wave clock input directly (per the Renesas product brief). This eliminates the need for external clock drivers in many systems, reduces board area, and ensures deterministic conversion timing critical for video digitizing, IF sampling, and digital oscilloscope front ends.
Typical applications include professional video digitizers, broadcast equipment, set-top box and graphics capture, digital oscilloscope and data acquisition front-ends, IF/RF signal sampling in communications, and medical imaging pre-processing. The single-channel 8-bit 50 MSPS profile matches legacy composite video (NTSC/PAL) digitizers and Y/C separation pre-stages in modern camera modules.
When designing with this part, ensure the analog input network complies with the datasheet's source-impedance and bandwidth requirements, and provide a clean, low-jitter clock to maximize SNR. Decouple AVDD and DVDD supplies with separate ferrite beads to isolate switching noise from the analog front end.

Applications typiques
ADC0804S050TS/C1:1 convient pour 6 applications: Professional Video Digitizing, Broadcast Set-Top Box Video Decoder, Digital Oscilloscope Front-End, IF/RF Signal Sampling (Communications), Medical Imaging Pre-Processing, Industrial Machine Vision Frame Grabber.
Professional Video Digitizing
The ADC0804S050TS/C1:1 at 50 MSPS is well-suited to composite video digitizing for broadcast, studio, and editing applications. The 8-bit resolution and TTL/CMOS-compatible outputs connect directly to video DSPs and frame-grabber ASICs without external level shifters, while the 50 MSPS sample rate provides sufficient oversampling margin (3x the 14.4 MSPS NTSC chroma bandwidth) to relax anti-alias filter design. Per Renesas family documentation, the SSOP-28 footprint supports multi-card designs with consistent thermal and signal-integrity characteristics across capture channels. Recommended companion parts: video processor ASIC, reconstruction DAC, and a sync separator.
Recommandé
Broadcast Set-Top Box Video Decoder
The ADC0804S050TS/C1:1 is used as the front-end digitizer in set-top boxes and digital TV receivers that decode baseband composite or Y/C video. Its 50 MSPS ceiling exceeds the typical 27 MSPS required for 480p NTSC and 480i PAL decoding, providing a 1.85x oversampling margin that simplifies downstream comb-filter and chroma-demodulator design. The single +5V supply (AVDD/DVDD) and built-in latches reduce BOM cost for high-volume consumer applications. The commercial 0C to +70C temperature range matches indoor set-top operating environments exactly.
Recommandé
Digital Oscilloscope Front-End
In entry-level digital-storage oscilloscopes and data-acquisition front-ends, the ADC0804S050TS/C1:1 provides the 50 MSPS sampling throughput needed to digitize repetitive and single-shot signals up to ~25 MHz analog input bandwidth. The TTL-compatible 8-bit output bus can be DMA-fed to an FPGA or microcontroller-based acquisition controller without external buffers. Per the Renesas datasheet, the pipelined-flash architecture delivers deterministic latency suitable for equivalent-time sampling expansion in oscilloscope designs.
Recommandé
IF/RF Signal Sampling (Communications)
For low-IF and digital-IF downconversion in software-defined radio and cable-modem receiver designs, the ADC0804S050TS/C1:1 samples 50 MSPS of IF bandwidth suitable for IF centers up to ~20 MHz. The 8-bit dynamic range handles 256-QAM and 64-QAM constellation decoding for downstream cable and broadcast demodulation. Per Renesas, the on-chip clock input accepts low-level sine wave directly, eliminating external clock-driver circuitry in many IF applications.
Recommandé
Medical Imaging Pre-Processing
In ultrasound front-end pre-processing and endoscopy imaging modules, the ADC0804S050TS/C1:1 provides 50 MSPS throughput at the front of the imaging pipeline. While the 8-bit resolution is insufficient for final diagnostic storage, it is well-matched to AGC-controlled video-style signals from ultrasound beamformers and CCD-based endoscopic cameras where downstream DSP performs noise reduction. The commercial 0C to +70C range and SSOP-28 surface-mount package suit medical-imaging OEM module integration. Per Renesas, low-power CMOS design reduces patient-side thermal load in compact imaging probes.
Recommandé
Industrial Machine Vision Frame Grabber
For factory-automation line-scan and area-scan camera digitizers, the ADC0804S050TS/C1:1 provides 50 MSPS of analog front-end throughput at 8-bit resolution sufficient for monochrome and Bayer-pattern color line-scan cameras. The TTL-compatible outputs feed directly into FPGA-based processing pipelines for real-time pattern recognition and quality control. Per the Renesas brief, the SSOP-28 surface-mount package and commercial temperature grade support conformal-coated industrial-camera PCBs without thermal-stress issues.

Notes de conception
Estimated: The ADC0804S050TS/C1:1 requires separate analog (AVDD) and digital (DVDD) +5V supply pins routed through independent ferrite beads to isolate high-frequency digital switching noise from the analog front end. Decoupling requires 100 nF ceramic caps placed within 5 mm of each supply pin and a 10 uF bulk tantalum or ceramic capacitor on each rail at the chip. A common-mode chokes on the analog input helps reject power-supply common-mode noise that would otherwise show up as channel-to-channel offset in multi-card designs.
Per the Renesas SSOP-28 datasheet recommendations: keep the analog input trace (AIN) short, guarded by AGND on both sides to minimize capacitive pickup. The 8-bit parallel digital output bus traces (D0-D7) should be length-matched within 1 mm if driving an FPGA at the system clock edge, with series 33 ohm damping resistors placed near the ADC outputs to suppress reflections. Separate the analog and digital ground planes with a single-point connection under the chip's AGND pin to avoid ground-loop-induced noise injection into the analog front end.
The ADC0804S050TS/C1:1 clock input (CLK) can be driven directly by a TTL square wave OR a low-level sine wave per the Renesas brief - this dual-mode clock input avoids the need for an external clock buffer in many designs. However, clock jitter directly degrades SNR; for 50 MSPS operation use a clock source with less than 5 ps RMS jitter to maintain datasheet SNR performance. Route the CLK trace over a continuous ground plane, never across split planes.
Common pitfalls when designing with the ADC0804S050TS/C1:1: (1) exceeding the analog input voltage range (typically 1 Vp-p around VREF) causes severe INL degradation - never drive AIN above AVDD or below AGND; (2) failing to enable the output enable (OE) pin during readout creates bus contention if the 8-bit data bus is shared - tie OE low at start of each conversion cycle; (3) forgoing the input anti-alias filter significantly increases out-of-band noise folded into the conversion result - include a simple RC filter at AIN matched to your analog input bandwidth.
