ADC0801S040TS/C1:1 Overview
An analog-to-digital converter is a semiconductor device that converts continuous analog signals into discrete digital codes for processing by microcontrollers, DSPs, FPGAs, or display pipelines. Within the broader signal-chain hierarchy, the ADC0801S040 belongs to the SAR-ADC family (Successive-Approximation Register ADC) -> ADC -> data converter -> mixed-signal IC -> integrated circuit. SAR ADCs deliver deterministic latency, single-cycle conversion, and a low external-component count, making them well suited for multiplexed or sample-on-demand systems rather than continuous-stream pipeline applications.
Key performance features include 8-bit resolution, 40 MSPS maximum sampling rate, single-channel single-ended analog input, parallel digital output interface, and a low-power sleep mode for portable or duty-cycled designs. The ADC0801S040 operates over the industrial -20 C to +75 C temperature range and supports a single 2.7 V to 5.5 V analog supply that is shared with the digital I/O domain, simplifying PCB power design.
Typical applications include professional video digitizers, composite-video or component-video capture front-ends, LCD/DLP projection engines, IF-stage digitizers, general-purpose high-speed data acquisition, and digital oscilloscope front-ends. The 20-SSOP footprint is footprint-compatible with the larger ADC0804S040 family, simplifying layout reuse between 8-bit and higher-resolution variants. When designing with this part, ensure the analog input is bandwidth-limited to less than half the sampling rate (Nyquist) and place a small RC anti-alias filter immediately at the analog input pin to limit wideband noise and kick-back from the internal sampling capacitor.

Typical Applications
ADC0801S040TS/C1:1 is suitable for 6 applications: Composite Video Digitizer Front-End, LCD / DLP Projection Engine, IF-Stage Digitizer for Communication Receivers, General-Purpose High-Speed Data Acquisition, Digital Oscilloscope Front-End, Camera Image Sensor Digitizer (Legacy CCD/CIS).
Composite Video Digitizer Front-End
The ADC0801S040's 40 MSPS sampling rate comfortably exceeds the 27 MSPS Nyquist requirement for NTSC/PAL composite video, while its 8-bit resolution preserves standard-definition broadcast quality. Placed directly after a video amplifier (e.g., AD8051) and anti-alias low-pass filter, it digitizes CVBS signals into 8-bit parallel words for downstream MPEG encoding or display pipelines. Compared with discrete sync-separator architectures, this single-chip ADC eliminates an entire analog front-end stage and reduces PCB area. Its CMOS/TTL-compatible outputs interface directly to legacy MPEG-1 encoders and FPGA-based video processors without level translation.
Recommended
LCD / DLP Projection Engine
The ADC0801S040's 8-bit resolution at 40 MSPS makes it an ideal input stage for front-projection engines accepting analog VGA or component-video sources. Its 20-LSSOP footprint sits directly on the projection engine controller board, converting RGB analog inputs to digital for scaling and deinterlacing ASICs. The device's single 3.3 V supply operation simplifies the multi-rail power tree typical of projection engine designs, and its sleep mode reduces standby power when the projector is in mute. Compared with legacy video decoder ICs, this ADC allows the system designer to bypass analog decoding entirely and apply digital scaling.
Recommended
IF-Stage Digitizer for Communication Receivers
In superheterodyne receivers, the ADC0801S040 digitizes the 10.7 MHz or 21.4 MHz intermediate-frequency signal after the IF amp and bandpass filter, enabling digital demodulation downstream. Its 40 MSPS rate provides 4x oversampling of the IF signal, relaxing analog anti-alias filter requirements. The 8-bit dynamic range is well matched to AGC-stabilized IF signals in narrowband FM/AM systems, and the parallel output interface feeds directly into DSP or FPGA-based demodulators. Compared with mixer-based analog demodulators, the ADC0801S040S040 simplifies the receiver architecture and enables software-defined demodulation.
Recommended
General-Purpose High-Speed Data Acquisition
For laboratory and industrial data-acquisition systems requiring 8-bit accuracy at multi-MHz sample rates, the ADC0801S040 provides a compact, low-power front-end. Its 40 MSPS throughput digitizes transient signals from photodiodes, ultrasonic transducers, or vibration sensors for storage in SRAM or streaming over USB. The parallel output interface allows direct DMA into microcontrollers or FPGAs without intermediate buffering. Compared with audio-bandwidth ADCs (typically <200 kSPS), this device extends acquisition capability by two orders of magnitude while maintaining the same 8-bit format expected by legacy DSP code.
Recommended
Digital Oscilloscope Front-End
The ADC0801S040's 40 MSPS sampling rate captures 20 MHz analog bandwidth signals, sufficient for many audio, ultrasonic, and low-RF bench-top measurements. Housed in a compact 20-LSSOP package, it integrates into the front-end analog board of low-cost digital oscilloscopes targeting education and hobbyist markets. Its CMOS/TTL outputs interface directly to low-cost FPGA-based timebases that perform triggering, decimating, and display rendering. Compared with the 100+ MSPS ADCs used in mainstream oscilloscopes, this part enables sub-$500 oscilloscope designs with adequate performance for non-RF measurements.
Recommended
Camera Image Sensor Digitizer (Legacy CCD/CIS)
The ADC0801S040 digitizes analog pixel outputs from legacy CCD or Contact Image Sensor (CIS) line-scan cameras, supporting pixel clock rates up to 40 MHz for high-speed document scanning. Its 8-bit resolution captures grayscale intensity with adequate dynamic range for OCR and barcode-reading applications. The parallel output interface feeds into ASICs or FPGAs performing shading correction, gamma adjustment, and USB streaming. Compared with modern camera-link interfaces, this ADC + FPGA combination provides a low-cost digitization path for embedded industrial inspection systems.

Design Notes
The analog input pin (AIN) of the ADC0801S040 presents a switched-capacitor load with kickback current transients at every clock edge. Place a low-impedance anti-alias RC filter (typically 50 ohm series resistor + 10 pF shunt to ground) within 5 mm of the AIN pin to limit wideband noise and damp kick-back. According to the datasheet, this filter's cutoff should be set to less than half the sampling rate (Nyquist). Estimated: input bandwidth at 40 MSPS Nyquist is 20 MHz, so a 33 pF + 50 ohm filter (cutoff ~96 MHz) provides 5x oversampling margin.
Use a star-ground topology with the ADC0801S040 GND pin as the single-point connection between analog and digital ground planes. The clock input pin (CLK) must be routed with 50 ohm controlled impedance and kept short (< 25 mm) to avoid jitter-induced aperture error. According to the datasheet, a 100 nF decoupling capacitor must be placed within 3 mm of VDD pins, and a 10 uF bulk capacitor should be placed near the package. NC pins should be left floating per the datasheet to avoid internal coupling.
Avoid driving the ADC0801S040's analog input from a high-impedance source - this causes harmonic distortion due to the internal sampling capacitor's charging transients. Use a wideband op-amp driver such as AD8051 or AD8000 with output impedance below 50 ohm at the maximum input frequency. According to the datasheet, exceeding the absolute maximum analog input voltage (VCC + 0.3 V) on AIN causes permanent damage. The OE (output enable) pin must be held low during the conversion to prevent bus contention.
Compliance Information
