XRD8775AID-F 概要
An analog-to-digital converter (ADC) is a data converter that translates real-world continuous analog signals into discrete digital codes for processing by microcontrollers, FPGAs, or DSPs. Flash and 2-step flash ADCs achieve the highest sampling rates among all ADC architectures by using parallel comparator banks, making them well-suited for video, instrumentation, and high-speed control loops. The XRD8775AID-F belongs to the hierarchy: ADC -> data converter -> signal chain IC -> mixed-signal semiconductor.
Key specifications include 8-bit resolution, 20 MSPS sampling rate, parallel digital interface, single 5V analog supply, internal S/H, 0V-to-VDD analog input range, and -40C to +85C operating temperature. The wide-body 20-SOIC package (0.295 inch / 7.50 mm width) provides robust thermal performance and ease of hand-soldering for prototyping. The part is offered in tube packaging for manufacturing.
The 2-step flash architecture trades a small number of comparator channels for a substantial reduction in die area and power consumption versus a full flash design, while still maintaining video-grade 20 MSPS throughput. Internal S/H bandwidth supports IF undersampling and video bandwidth applications. The CMOS process ensures low power, latch-up free operation, and stable performance across the industrial temperature range.
Typical applications include video digitisation, CCD camera front ends, digital oscilloscopes, ultrasound front-end preprocessing, IF sampling in communications receivers, and industrial process control loops. The combination of wide analog input range and integrated S/H simplifies board-level design for low-channel-count high-speed data acquisition.
When designing with this part, place a 0.1 uF ceramic decoupling capacitor as close as possible to the VDD pin and a bulk tantalum or electrolytic capacitor on the analog supply rail. The reference pin requires a low-impedance source; use an op-amp buffer or a dedicated reference IC if the application demands better than 8-bit absolute accuracy.

主な用途
XRD8775AID-F の用途: 7 件s: Video Signal Digitisation, Industrial Process Control Data Acquisition, CCD Camera Front-End Processing, Digital Oscilloscope Front-End, IF Sampling in Communications Receivers, Ultrasound Preprocessing Front-End, Portable Test and Measurement Instrumentation.
Video Signal Digitisation
The XRD8775AID-F's 20 MSPS sampling rate and 8-bit resolution directly support composite and component video digitisation up to ~10 MHz analog bandwidth. Its integrated sample-and-hold eliminates external T/H circuitry, reducing board area in camera front-ends, video capture cards, and broadcast equipment. Operated from a single 5V supply with 0V-to-VDD analog input range, the device accepts standard 1Vpp video signals with simple AC coupling. Pin-compatible 20-SOIC packaging keeps the analog and digital grounds well-separated, an important consideration for video SNR.
おすすめ
Industrial Process Control Data Acquisition
The XRD8775AID-F serves as a single-channel, high-speed digitiser for industrial control loops where sensor bandwidth exceeds SAR ADC capabilities. Its -40C to +85C industrial temperature range and 5V CMOS latch-up-free process suit factory-floor environments. Typical loop bandwidths of 100 kHz to 1 MHz are well within the 20 MSPS throughput, allowing oversampling for noise averaging. The 0V-to-VDD input range accepts unipolar sensor outputs directly, and the wide-body 20-SOIC package handles factory thermal stress.
おすすめ
CCD Camera Front-End Processing
CCD output stages require high-speed, single-channel 8-bit ADCs to digitise pixel rates up to 20 MSPS. The XRD8775AID-F's internal sample-and-hold captures the CCD's fast reset transitions accurately, while its 5V CMOS design integrates cleanly with CCD bias and timing circuits. The wide input range (0V to VDD) accommodates CCD output levels without additional level shifting. Its 20-SOIC wide-body package offers robust thermal performance for compact camera module designs.
おすすめ
Digital Oscilloscope Front-End
The XRD8775AID-F is well-matched to single-channel 20 MSPS bench and embedded oscilloscope designs, particularly as an auxiliary ADC or trigger qualification channel. Its internal S/H enables accurate single-shot capture of repetitive waveforms up to the Nyquist limit (~10 MHz). The parallel digital interface simplifies FPGA/CPLD-based trigger and display logic. The wide-body 20-SOIC package simplifies hand-soldering during prototype builds, important for low-volume test equipment.
おすすめ
IF Sampling in Communications Receivers
Communications IF stages at 5-10 MHz benefit from the XRD8775AID-F's 20 MSPS throughput and integrated S/H. The device supports direct IF undersampling of intermediate frequency signals, allowing a single ADC to digitise the band for downstream DSP. Its single 5V supply operation is compatible with most RF front-end designs, and the latch-up-free CMOS process ensures robust performance in electrically noisy environments.
おすすめ
Ultrasound Preprocessing Front-End
Medical and industrial ultrasound front-ends require single-channel ADCs capable of digitising pre-conditioned transducer signals at multi-MHz rates. The XRD8775AID-F's 20 MSPS sampling and internal S/H capture transient echo waveforms accurately. Its 0V-to-VDD analog input range simplifies transducer interface design, and its industrial -40C to +85C temperature rating covers both clinical and harsh-environment ultrasound applications.
おすすめ
Portable Test and Measurement Instrumentation
Battery-powered handheld test instruments benefit from the XRD8775AID-F's modest 75 mW power consumption and single 5V supply operation. The internal S/H removes the need for power-hungry external T/H amplifiers, extending battery life. The wide-body 20-SOIC package supports through-hole repair and field servicing. With 8-bit resolution and 20 MSPS throughput, the part is suited for handheld oscilloscopes, logic analyser pods, and field signal analysers.

設計ノート
Place a 0.1 uF ceramic decoupling capacitor as close as possible to the VDD pin (within 2-3 mm trace length) to suppress high-frequency digital switching noise from coupling into the analog input. Add a 10 uF tantalum or ceramic bulk capacitor on the analog supply rail to handle lower-frequency supply transients. The XRD8775AID-F draws about 15 mA (75 mW at 5V) plus reference current, so the supply should be rated for at least 25 mA continuous.
Separate analog and digital ground planes and join them at a single point near the ADC's AGND pin to prevent digital return currents from corrupting the analog input. Route the sampling clock (CLK) as a short, impedance-controlled trace (typically 50 ohm) and place it away from the analog input trace to minimise digital feedthrough. The output enable (OE) signal should be referenced to the digital ground (DGND).
The reference pin (VREF) requires a low-impedance DC source for best 8-bit linearity; use a dedicated voltage reference IC (e.g., a 5V reference with <10 ppm/deg C drift) or buffer the reference with a low-noise op-amp. For applications where 8-bit absolute accuracy is not required, VREF can be tied to VDD via a 10 ohm isolation resistor, but expect degraded INL and DNL.
Estimated: at VIN approaching VDD or AGND within ~100 mV, the XRD8775AID-F's input stage may exhibit reduced linearity. Design the analog front-end to scale sensor signals to the 0.2V-to-(VDD-0.2V) range for best 8-bit performance. Additionally, the device's internal S/H requires the analog input source to settle within one clock period - use an op-amp driver with at least 20 MHz bandwidth and fast slew rate for full-speed 20 MSPS operation.
