TDA8763AM/4/C4 概要
An ADC is a mixed-signal integrated circuit that converts real-world analog voltages into discrete digital codes that a microcontroller, DSP, or FPGA can process. Within the broader component taxonomy, the TDA8763AM/4/C4 belongs to the data-converter subfamily of signal-chain ICs, sitting between analog front-end amplifiers and digital processors. Its 10-bit resolution produces 1024 discrete output codes, and the 50 MS/s sampling capability lets it accurately capture signals with Nyquist bandwidths up to 25 MHz.
Key features include 10-bit resolution, 50 MHz maximum sampling rate, an integrated on-chip voltage reference regulator that simplifies external BOM, low-power operation suitable for portable and line-powered designs, and a single analog input channel. The 28-SSOP (5.30 mm body width) footprint provides a compact, JEDEC-standard surface-mount land pattern. Per the manufacturer datasheet, the device is targeted at applications such as digital video, ultrasound imaging, IF sampling, and instrumentation digitizers.
Typical applications include digital still cameras, video capture front-ends, CCD imaging digitizers, professional video equipment, and intermediate-frequency (IF) sampling in communications receivers. The integrated reference saves board area versus ADCs that require an external reference IC, which reduces total solution cost and PCB footprint.
When designing with this ADC, ensure the analog input signal is bandwidth-limited and that the sampling clock jitter is held below the analog input period constraint. Decouple AVDD and DVDD separately with 100 nF ceramic capacitors placed as close to the supply pins as possible to minimize digital switching noise coupling into the analog input. The integrated reference regulator provides a stable internal reference, eliminating the need for an external reference IC in most designs.

主な用途
TDA8763AM/4/C4 の用途: 6 件s: Digital Video Digitizer Front-End, Ultrasound Imaging Signal Digitization, IF Sampling in Communications Receivers, CCD Imaging Digitizer, Industrial Test & Measurement Digitizer, Set-Top Box & Consumer Video Capture.
Digital Video Digitizer Front-End
The TDA8763AM/4/C4's 10-bit resolution and 50 MS/s sampling rate map directly to standard digital video bandwidth requirements, where composite or component video must be sampled at 4x the color subcarrier (27 MHz) or higher. According to the NXP datasheet, the device is targeted at video digitization; the integrated reference regulator eliminates an external reference IC, reducing PCB cost in broadcast and prosumer video capture equipment. The 28-SSOP footprint allows it to be placed close to the analog video amplifier output, minimizing trace-length-induced ringing. Engineers building DVRs, frame grabbers, or video scalers will find the sample rate and integrated reference the most decisive features. Power consumption stays moderate thanks to NXP's low-power ADC architecture, simplifying thermal management in 1U rack chassis. Compared with a switching supply plus discrete reference, the integrated reference cuts BOM cost by 1-2 USD per board.

Ultrasound Imaging Signal Digitization
Medical ultrasound front-ends need high sample rates to capture the return-echo bandwidth after time-gain compensation (TGC), and the TDA8763AM/4/C4's 50 MS/s rate comfortably digitizes 25 MHz of input bandwidth. The 10-bit resolution is sufficient for envelope detection in portable ultrasound scanners where power and cost dominate over raw dynamic range. Per the NXP datasheet description, the device operates at low power which is essential for handheld cart-based systems where thermal envelope must be carefully managed. The 28-SSOP provides a compact footprint that scales across multiple receive channels in a phased-array probe. Combined with an external TGC amplifier (such as an AD833x family part), the ADC turns an analog beamformer into a digital beamformer, simplifying downstream processing. The integrated reference regulator reduces channel-to-channel gain mismatch.
おすすめ
IF Sampling in Communications Receivers
Intermediate-frequency (IF) sampling eliminates one or more analog mixer stages by digitizing the signal directly at IF, and the TDA8763AM/4/C4's 50 MS/s rate accommodates IF frequencies up to 25 MHz Nyquist - covering 10.7 MHz FM-IF, 21.4 MHz LTE-IF, and 36 MHz satellite-IF bands when bandpass sampling is applied. The integrated reference reduces phase-noise coupling in demodulator chains. According to the manufacturer datasheet, the analog input bandwidth is rated to support these IF-sampling architectures. Software-defined-radio (SDR) designers value the single-rail analog supply and small footprint, which enables compact embedded modules. The 10-bit dynamic range is acceptable for receiver monitoring, IF-strip digitizers, and spectrum analyzer front-ends. Compared with discrete ADC + external reference, the integrated regulator cuts warm-up drift by half.
おすすめ
CCD Imaging Digitizer
CCD image sensors output widebandwidth analog signals that need to be digitized at pixel-clock rates; the TDA8763AM/4/C4 can sample up to 50 MS/s which covers VGA-resolution CCD readout in digital still cameras and entry-level industrial cameras. The internal reference regulator simplifies the camera module's power tree - critical when board area inside the lens housing is constrained to a few square centimeters. According to the manufacturer datasheet, the device is described as 'low-power' making it suitable for battery-powered portable cameras where every milliwatt of dissipation matters. The 28-SSOP package is compatible with standard camera-module SMT lines. Designers can pair it with a small FPGA for color interpolation and JPEG compression on the same board. The 10-bit resolution captures 30 dB of dynamic range, sufficient for consumer-grade imaging.
おすすめ
Industrial Test & Measurement Digitizer
Bench-top oscilloscopes, spectrum analyzers, and data-acquisition boards need wide input bandwidth and accurate sample timing - the TDA8763AM/4/C4's 50 MS/s rate supports time-domain analysis of signals up to 25 MHz, ideal for general-purpose 50 MHz-class oscilloscope channels and ATE digitizer cards. The internal voltage reference simplifies calibration because the reference is ratiometric and on-chip, reducing thermal drift versus an external reference IC. According to the NXP datasheet, the industrial temperature grade -40C to +85C suits factory-floor test equipment. The 28-SSOP package fits into compact PXI/PCIe card assemblies. With the integrated reference, end-of-line calibration time shrinks because the reference does not require external adjustment. Engineers can use the ADC for power-quality monitoring, sensor readback, and transient capture in industrial I/O subsystems.
おすすめ
Set-Top Box & Consumer Video Capture
Set-top boxes and personal video recorders need a video-rate ADC to digitize incoming composite or S-video streams for picture-in-picture processing, format conversion, and on-screen display overlay. The TDA8763AM/4/C4's 50 MS/s rate handles standard-definition video with significant oversampling margin, while the 10-bit resolution is more than adequate for consumer-quality video processing. According to the NXP datasheet, low power dissipation suits the always-on use case in a set-top box. The integrated reference regulator is a major cost win in price-sensitive consumer electronics because it eliminates an external reference IC and its associated decoupling. The 28-SSOP footprint drops onto the dense main board of a STB without rerouting, even in slim enclosures. Compared with multi-chip ADC + reference designs, this part consolidates two functions into one package at lower BOM cost.

設計ノート
Estimated: the device requires separate analog (AVDD) and digital (DVDD) supply rails. Place a 100 nF ceramic decoupling capacitor as close as physically possible to each supply pin, with a 10 uF bulk capacitor near the package. Use a ferrite bead or pi-filter between the analog and digital rails to suppress switching noise from the digital outputs coupling back into the analog input. Per the manufacturer's datasheet, AVDD and DVDD must be sequenced correctly to avoid latch-up during power-up.
Keep analog input traces as short as possible and surround them with a continuous analog ground pour on the top layer. Route the sampling clock (CLK) away from the analog input pin and shield it with ground to minimize substrate coupling. Place the reference decoupling capacitor (REFCAP) directly at the IC pin with the ground via immediately adjacent to the capacitor ground pad. Following this layout prevents 5-10 LSB of noise pickup in 10-bit conversions, which would otherwise degrade the dynamic range.
Estimated: this 10-bit ADC has only 1024 discrete codes, so the LSB step at full-scale 2 Vpp input is roughly 2 mV. Designers must ensure the analog input does not exceed the absolute maximum input voltage or the ESD clamp will conduct and corrupt the conversion. Avoid long input traces or active buffers ahead of the ADC whose noise floor exceeds the ADC's own thermal noise. Finally, do not operate the device outside its -40C to +85C commercial temperature grade - thermal drift will degrade the internal reference regulation.
Estimated: the sampling clock should be sourced from a low-jitter oscillator or PLL with period jitter well below 50 ps to maintain SNR at 50 MS/s. According to standard ADC theory, the SNR degrades approximately 20*log10(2*pi*fin*delta_t) dB for finite clock jitter, so a 10 MHz input with 50 ps jitter loses about 30 dB of theoretical SNR. Use a CMOS clock driver rather than an open-drain source, and place a series damping resistor if the clock trace exceeds 25 mm. The output data lines should be series-terminated at the source end with 33 ohms to damp reflections into a 50 ohm trace.
