IDTADC1004S030TS-C18 概要
A flash ADC is the fastest ADC architecture, using 2^N-1 parallel comparators to convert an analog input into an N-bit digital code in a single clock cycle. The flash architecture makes ADC1004S030TS ideal for applications where latency and sampling speed dominate over resolution, such as digital oscilloscopes, digital storage scopes, video digitizers, radar pulse capture, and high-speed instrumentation. Compared with successive-approximation (SAR) and sigma-delta ADCs, flash converters trade resolution and power efficiency for sub-microsecond conversion times.
Key features of the IDTADC1004S030TS-C18 include 10-bit resolution, 30 MSPS maximum sampling rate, single 5V analog and 5V digital supply rails, and a parallel CMOS-compatible digital output bus. The -C18 suffix denotes the tape-and-reel packaging orientation per Renesas/IDT ordering codes. The 28-SSOP (5.30 mm body width) package provides a compact footprint while retaining easy manual soldering pads for prototype work.
Typical applications include digital oscilloscope input channels, CCD digitizers, medical imaging front ends, IF (intermediate frequency) signal digitizers in communications receivers, and laser rangefinder pulse capture. The single 5V supply simplifies power-tree design, while the parallel output allows direct connection to FPGAs or ASICs for real-time processing. Designers should pay attention to input bandwidth and clock jitter because flash ADC performance is highly sensitive to clock-edge quality and input driver settling time.

主な用途
IDTADC1004S030TS-C18 の用途: 6 件s: Digital Oscilloscope Input Channel, CCD / Image Sensor Digitizer, IF Signal Digitizer for Communications Receivers, Laser Rangefinder Pulse Capture, Medical Ultrasound Receiver, Industrial Test & Measurement Instrumentation.
Digital Oscilloscope Input Channel
The IDTADC1004S030TS-C18 is well suited for digital oscilloscope front-end digitizers where 30 MSPS sampling provides approximately 15 MHz of usable analog bandwidth per Nyquist. Its flash architecture converts the analog input in a single clock cycle, eliminating pipeline delay and enabling real-time triggering on transient events. The 10-bit resolution yields ~60 dB dynamic range, sufficient for general-purpose bench scopes, while the parallel CMOS output interfaces directly to an FPGA capture buffer without serializer overhead. Designers typically add an antialiasing low-pass filter, a wideband front-end amplifier, and a stable 30 MHz clock source with sub-50 ps jitter.
おすすめ
CCD / Image Sensor Digitizer
In CCD and CMOS image sensor digitizers, the IDTADC1004S030TS-C18 captures pixel-rate analog outputs at speeds up to 30 MSPS, sufficient for VGA-class video digitization. The 10-bit resolution preserves 1024 grayscale levels, matching typical CCD dynamic range without compression. The single 5V supply rail simplifies the analog front-end power tree, while the separate digital supply rail reduces switching noise coupling into the analog pixel stream. Typical designs include correlated double sampling (CDS) followed by the ADC, with the 10-bit parallel output captured into an FPGA line buffer for image processing.
おすすめ
IF Signal Digitizer for Communications Receivers
The IDTADC1004S030TS-C18 digitizes intermediate frequency (IF) signals in software-defined radio and communications receivers operating up to ~15 MHz IF. The flash architecture provides sub-microsecond latency, enabling real-time DSP demodulation of AM, FM, and QAM signals. The 10-bit resolution captures enough dynamic range for typical IF signal levels, while the parallel CMOS output streams samples directly to an FPGA for FFT, filtering, and demodulation. Designers should place a bandpass filter and a wideband IF amplifier ahead of the ADC input to limit out-of-band noise and avoid folding back into Nyquist.
おすすめ
Laser Rangefinder Pulse Capture
In pulsed laser rangefinder systems, the IDTADC1004S030TS-C18 captures the time-of-flight return pulse at 30 MSPS, providing ~33 ns time resolution per sample. This resolution supports meter-class distance accuracy after digital signal processing in an FPGA. The flash converter's single-cycle latency ensures no missed pulses, while the 10-bit dynamic range captures both near-target strong returns and far-target weak returns without front-end gain switching. The 28-SSOP package is small enough for handheld rangefinder designs.
おすすめ
Medical Ultrasound Receiver
In medical ultrasound receivers, the IDTADC1004S030TS-C18 digitizes the post-TGC (time-gain-compensated) RF echo signal at 30 MSPS, sufficient for probes operating in the 2-15 MHz range. The 10-bit resolution provides the dynamic range needed for capturing both surface and deep-tissue echoes without saturating. The flash architecture introduces no pipeline delay, which is critical for real-time B-mode imaging. The 28-SSOP package fits inside compact portable ultrasound probe electronics, where PCB area is constrained.
おすすめ
Industrial Test & Measurement Instrumentation
In industrial bench instruments such as power analyzers, data loggers, and waveform recorders, the IDTADC1004S030TS-C18 provides a cost-effective, moderate-speed digitizer with 10-bit resolution and 30 MSPS throughput. Its parallel CMOS output allows direct capture into a microcontroller or FPGA buffer for processing, while the 28-SSOP package supports both hand-soldered prototypes and reflow mass production. Designers benefit from the flash architecture's single-cycle latency for event-triggered captures, and from the dual 5V analog/digital rails for clean measurement of noisy industrial signals.

設計ノート
Separate analog and digital ground planes, joined only at a single point near the ADC's GND pins. Place 100 nF ceramic decoupling capacitors on VCCA (pin 1) and VCCD (pin 8) within 5 mm of the supply pins. The clock trace (pin 6) should be routed with 50 ohm controlled impedance and kept away from the analog input trace to avoid coupling. The reference voltage pin (pin 4) requires a low-ESR decoupling capacitor and a low-noise buffer for stable 10-bit performance.
Clock jitter is the dominant noise source for flash ADCs at high input frequencies. Use a low-jitter clock oscillator (under 5 ps RMS) and route the clock trace with a ground guard trace. Keep the analog input bandwidth matched to the Nyquist frequency (15 MHz for 30 MSPS) with an antialiasing low-pass filter. Estimated: with 5 ps RMS jitter and 15 MHz input, the SNR degradation is approximately 6 dB, dropping effective bits by ~1.0.
Do not exceed the maximum analog input voltage rating (typically VCCA + 0.3 V). Add ESD protection diodes at the analog input for production designs. The output enable (OE, pin 7) must be driven low to enable the output bus; leaving it floating can cause indeterminate output states. Ensure the input drive amplifier has sufficient slew rate to settle the ADC's internal track-and-hold within one clock period at full sampling rate.
