IDTADC1003S050TS-C18 概述
An Analog-to-Digital Converter (ADC) is a mixed-signal data-acquisition component that converts a continuous-time analog voltage on its input pin into a discrete digital code. ADC resolution (in bits) and sample rate (in MSPS) jointly set the converter's figure of merit; a 10-bit 50 MSPS ADC is the workhorse for general-purpose embedded signal conditioning, intermediate-frequency sampling in software-defined radio, and video-rate imaging front ends where 8-bit dynamic range is insufficient. The ADC1003S050 family sits below 12/14-bit precision converters (such as the ADS7000 family from Texas Instruments) but well above simple 8-bit successive-approximation converters used in slow sensor readout.
Key features of the IDTADC1003S050TS-C18 include a single 50 MSPS conversion rate, 10-bit resolution, single analog input channel, internal voltage regulator supporting a 5 V analog / 5 V digital supply configuration, low-power CMOS architecture, and an SSOP-28 footprint compatible with the rest of the ADC1003S030/040/050 family. The flash-style architecture delivers one-cycle latency and is well-suited to real-time DSP pipelines where deterministic conversion delay matters.
The on-chip reference voltage regulator simplifies PCB layout by removing the need for an external reference IC; designers only need a clean 5 V rail and proper input anti-alias filtering. Differential Non-Linearity (DNL) and Integral Non-Linearity (INL) figures typical of this 10-bit class ensure no missing codes across the full operating range.
Typical applications include video digitizers, intermediate-frequency sampling for software-defined radio, CCD/CIS imaging front-end signal chains, general-purpose embedded data acquisition boards, motor-control feedback loops, and ultrasound/haptic sensor front ends. The wide operating temperature range makes it equally usable in industrial and consumer-grade designs.
Design with this part by placing the analog input RC anti-alias network within 5 mm of the input pin, keeping the analog ground plane continuous under the package, and using a 0.1 uF decoupling capacitor on each supply pin. Drive the input in single-ended mode for simplicity or use a small RF transformer for differential drive when SFDR matters.

典型应用
IDTADC1003S050TS-C18 适用于 6 应用s: Standard-Definition Video Digitizer, Software-Defined Radio IF Sampling, CCD / CIS Imaging Front End, Industrial Data Acquisition Module, Motor Control Position Feedback, Ultrasound / Haptic Sensor Front End.
Standard-Definition Video Digitizer
The IDTADC1003S050TS-C18 fits standard-definition video digitization (ITU-R BT.601 at 27 MSPS) with 10-bit resolution providing 1024 luminance quantization levels versus only 256 in 8-bit parts. With 50 MSPS of headroom it supports oversampling 2x to ease analog anti-alias filter roll-off. The on-chip 5 V regulator simplifies the PCB to a single analog rail; place a 75-ohm termination and 0.1 uF AC-coupling cap at the analog input. DNL of one LSB or better at 10 bits avoids visible contouring in flat-color test patterns.
推荐
Software-Defined Radio IF Sampling
The IDTADC1003S050TS-C18 samples intermediate-frequency (IF) signals in software-defined radio receivers at up to 50 MSPS, giving 25 MHz of usable Nyquist bandwidth after digital downconversion. The 10-bit dynamic range is sufficient for narrow-band FM/AM demodulation and low-order QAM constellations when paired with a fixed-gain front-end LNA. Drive the analog input through an RF transformer for differential mode to maximize SFDR; the on-chip regulator rejects digital switching noise on the 5 V rail.
推荐
CCD / CIS Imaging Front End
The IDTADC1003S050TS-C18 converts analog pixel data from CCD or CMOS image sensors to digital codes at 50 MSPS, supporting VGA-resolution sensors at 30 fps and QVGA at higher frame rates. The 10-bit depth captures 1024 gray levels, sufficient for industrial machine-vision inspection. Place the ADC close to the sensor output to minimize analog trace length and use a low-jitter clock from a dedicated PLL (such as the CDCE906) to preserve aperture jitter budget at < 1 ps RMS.
推荐
Industrial Data Acquisition Module
The IDTADC1003S050TS-C18 serves as the front-end converter in industrial data-acquisition modules digitizing 4-20 mA current-loop-derived voltages, thermocouple amplified signals, and strain-gauge bridge outputs. The 50 MSPS throughput oversamples the input for digital averaging to push effective resolution beyond 10 bits, while the integrated 5 V regulator rejects noisy 24 V industrial bus transients. The 28-SSOP package is easy to hand-prototype on breakout PCBs and is rated for the industrial temperature range.
推荐
Motor Control Position Feedback
The IDTADC1003S050TS-C18 digitizes resolver or encoder-derived analog signals in BLDC and servo motor control loops at 50 MSPS, enabling sub-microsecond position updates. The one-cycle pipelined latency supports real-time field-oriented control (FOC) updates without added phase delay. The single 5 V supply simplifies isolated DC-DC design, and the 10-bit resolution is adequate for resolver-to-digital conversion when paired with an exciter reference signal conditioning stage.
推荐
Ultrasound / Haptic Sensor Front End
The IDTADC1003S050TS-C18 digitizes analog front-end signals from piezoelectric ultrasound transducers or MEMS haptic sensors at 50 MSPS, capturing the high-frequency content of acoustic emissions. The 10-bit resolution is appropriate for envelope-detected sub-bands; pair with an external VGA/LNA (e.g., AD8331) for full ultrasound beamforming. The 28-SSOP footprint integrates easily into compact handheld diagnostic enclosures.

设计说明
The IDTADC1003S050TS-C18 integrates a 5 V regulator for both analog and digital rails; however, decouple AVCC and DVCC separately with 0.1 uF ceramic capacitors placed within 3 mm of each supply pin. Add a 10 uF tantalum or polymer bulk capacitor on each rail to absorb the digital switching transient when the output bus toggles simultaneously. A common-mode ferrite bead between AVCC and DVCC planes reduces high-frequency noise injection from the digital core into the analog sampling capacitor.
Keep the analog input trace to pin 1 as short as possible (under 10 mm) and surround it with a continuous analog ground pour on the top layer under the SSOP-28 package. Use a 50-ohm microstrip or coplanar-waveguide-with-ground topology if the input analog bandwidth exceeds 100 MHz to prevent reflection and ringing. Avoid routing digital output lines (D0-D9) under the analog input pin region to minimize digital-to-analog crosstalk.
Do not assume the analog input is DC-coupled - the input is typically AC-coupled through an external capacitor to remove DC bias. Drive the sample clock (CLK) with a low-jitter source (aperture jitter < 1 ps RMS) to preserve SNR; a noisy TCXO or PLL output can reduce effective ENOB by 2-3 bits. The output enable pin (OE, active-low) must be tied low or driven by a logic signal before clocking begins; floating OE may cause bus contention on D0-D9.
