IDTADC1004S050TS-C18 개요
A flash ADC is the fastest ADC architecture, using 2^N - 1 parallel comparators to digitize a sample in a single comparator clock edge, in contrast to successive-approximation (SAR) converters that require N clock cycles per conversion. Because of this single-cycle conversion, flash ADCs dominate applications requiring sub-microsecond acquisition of wideband analog signals, such as digital oscilloscopes, radar receivers, and high-speed instrumentation. The tradeoff is higher power consumption and larger die area, which is why the ADC1004S family is housed in a 28-SSOP with a thermal pad to dissipate the heat generated at 50 MSPS.
Key features include 10-bit resolution, 50 MSPS maximum sampling rate, single analog input channel, single 3 V or 5 V analog supply, CMOS digital I/O, and an internal reference ladder. The flash comparator array delivers sub-100 ns conversion latency, while the wide input bandwidth allows direct sampling of IF and baseband signals in communications and test equipment. The 28-SSOP (TS) package is a JEDEC-standard 5.30 mm body width with 0.65 mm pitch and a center thermal pad that must be soldered to a copper pour for rated thermal performance.
Typical applications include digital oscilloscope front ends, radar and lidar digitizers, communications IF sampling, medical imaging capture, and high-speed industrial inspection. The 50 MSPS rate makes it particularly suitable for digitizing signals up to about 20 MHz (Nyquist-limited) with low pipeline delay. When designing with this part, provide adequate analog input bandwidth limiting (typically a low-pass filter at f_IN <= 25 MHz) to prevent aliasing of out-of-band noise into the baseband.

일반적인 애플리케이션
IDTADC1004S050TS-C18 적합 용도: 6 애플리케이션s: Digital Oscilloscope Front End, Radar/Lidar Signal Capture, Communications IF Sampling, Medical Imaging Capture, High-Speed Industrial Inspection, Test and Measurement Instrumentation.
Digital Oscilloscope Front End
The IDTADC1004S050TS-C18's 10-bit resolution at 50 MSPS and flash (single-cycle) architecture make it a strong front-end digitizer for low-to-mid frequency oscilloscope channels. Flash converters deliver sub-microsecond latency versus SAR or pipelined ADCs, preserving real-time waveform fidelity for trigger detection on signals up to about 20 MHz (Nyquist-limited). Placed directly after the analog front-end attenuator/amplifier and an anti-alias low-pass filter, it converts the conditioned analog signal into a 10-bit CMOS bus sampled by an FPGA or DSP. Designers should add a 1 kohm source-impedance input buffer and place 0.1 uF/10 uF decoupling on AVDD/DVDD for stable noise performance.
추천
Radar/Lidar Signal Capture
Radar and lidar receivers digitize return pulses with sub-microsecond timing, where the flash architecture of the IDTADC1004S050TS-C18 eliminates pipeline delay. At 50 MSPS the converter captures baseband IF returns up to 25 MHz with 10-bit amplitude resolution, sufficient for short-range automotive or industrial radar return detection. Pair the ADC with a fast analog front-end LNA and sample the converted bus into an FPGA fabric for range/Doppler processing. Thermal management is critical - the SSOP thermal pad should connect to at least 1 square inch of inner-layer copper.
추천
Communications IF Sampling
Software-defined radios and IF-strip digitizers benefit from the IDTADC1004S050TS-C18's 50 MSPS throughput and 10-bit resolution for sampling intermediate-frequency signals after downconversion. Flash conversion provides deterministic 1-clock latency, simplifying downstream synchronization in coherent demodulators. Place the ADC after the IF bandpass filter and SAW anti-alias filter; feed the 10-bit CMOS bus into an FPGA running digital downconversion. The 3 V/5 V single-supply operation simplifies integration into legacy 5 V IF chain designs.
추천
Medical Imaging Capture
Ultrasound and optical-imaging front-ends use the IDTADC1004S050TS-C18 to digitize conditioned transducer return signals at rates up to 50 MSPS. The 10-bit resolution is adequate for B-mode ultrasound envelopes and pulse-oximetry photodiode amplification chains. Single 3 V/5 V supply operation supports battery-powered portable patient monitors. Provide a low-noise LNA before the ADC and shield the analog input traces with a ground guard ring to maintain CMRR in clinical environments.
추천
High-Speed Industrial Inspection
Automated optical inspection (AOI) and machine-vision systems digitize line-scan camera or photodiode outputs at high rates, where the IDTADC1004S050TS-C18's 50 MSPS rate and 10-bit dynamic range match typical 8-bit camera signal chains plus headroom for gain. Flash conversion supports real-time defect detection on conveyor lines running at several meters per second. Use the ADC downstream of a transimpedance amplifier and AC-coupling capacitor; route the 10-bit CMOS output to an FPGA for feature extraction.
추천
Test and Measurement Instrumentation
Bench-top signal analyzers, function generators, and automated test equipment use the IDTADC1004S050TS-C18 for waveform capture and feedback loops. The flash architecture provides deterministic latency, ideal for closed-loop stimulus-response systems where conversion delay must be precisely compensated. At 50 MSPS the ADC supports digitizing signals up to 25 MHz, covering audio, ultrasonic, and low-RF test waveforms. Add a front-end programmable-gain amplifier to extend dynamic range beyond the ADC's native 10 bits.

- Highest speed grade in the ADC1004S family (vs IDTADC1004S040TS-C18)

설계 노트
Estimated: at 50 MSPS the flash comparator array toggles ~10,000 times per microsecond; route AVDD and DVDD as separate planes with ferrite-bead isolation and place 10 uF tantalum plus 0.1 uF ceramic decoupling within 5 mm of the supply pins. The 28-SSOP thermal pad must be soldered to a continuous ground pour (at least 1 square inch of inner-layer copper) to keep junction temperature within the -40 to +85 C operating range.
Add a passive anti-alias low-pass filter at the analog input with -3 dB cutoff at 25 MHz (half the sampling rate). The 50 MSPS flash ADC has wide input bandwidth and will alias out-of-band noise into the baseband. Place the filter within 10 mm of the AIN pin and use a 50 ohm source-impedance driver to damp reflections on the analog trace.
Estimated: do not exceed 50 MSPS sampling rate - the device's internal comparator settling time budget is sized for 50 MSPS operation only. Sampling above 50 MSPS causes metastability errors that surface as sparkle codes in the digital output. Also, ensure the CLK input has < 1 ns rise/fall time with stable amplitude; a slow clock introduces aperture jitter and degrades SNR.
