ADC14DC105CISQE/NOPB - Dual 14-Bit 105 MSPS ADC | Texas Instruments
MPN: ADC14DC105CISQE/NOPB ✓ فعالADC14DC105CISQE/NOPB جائزہ
An analog-to-digital converter (ADC) is a semiconductor device that transforms continuous analog signals into discrete digital codes. The ADC14DC105 belongs to the high-speed pipelined ADC family, which sits within the broader category of data converters used in mixed-signal systems. Pipelined ADCs use multiple cascaded low-resolution stages to achieve high sample rates while maintaining resolution, making them the standard architecture for communications, imaging, and instrumentation front-ends operating above 10 MSPS.
Key features include 14-bit resolution, 105 MSPS sampling rate per channel, dual simultaneous-sampling inputs, low-latency CMOS-compatible parallel output, single 1.8V analog supply, and an exposed thermal pad. The CMOS parallel output provides low-power, easy-to-interface digital signaling suitable for FPGA or DSP data capture. The industrial -40C to +85C operating range supports both commercial and ruggedized environments.
The pipelined architecture of the ADC14DC105 uses multi-bit-per-stage conversion with digital error correction, achieving high spurious-free dynamic range (SFDR) and signal-to-noise ratio (SNR) at the full 105 MSPS conversion rate. The dual-channel design allows correlated dual-channel acquisition from a single sampling clock, which is essential for I/Q baseband digitization, time-interleaved multi-antenna receivers, and medical imaging arrays.
Typical applications include communications baseband receivers, medical imaging (ultrasound beamformers), radar signal processing, portable test and measurement instrumentation, and multi-channel data acquisition systems. The wide sampling rate headroom (105 MSPS per channel allows significant oversampling at lower input bandwidths to relax analog anti-alias filter design).
When designing with this device, place the 60-WFQFN exposed pad on a continuous ground copper pour to minimize thermal rise and provide a low-impedance ground reference. Provide a clean low-noise analog supply (typically LDO-regulated) and short, matched trace lengths to both analog inputs to preserve channel-to-channel gain and phase matching.

عام استعمالات
ADC14DC105CISQE/NOPB کے لیے موزوں ہے 6 ایپلیکیشنs: Communications Baseband Receiver, Medical Ultrasound Beamforming, Radar and Lidar Signal Processing, Portable Test and Measurement, Multi-Channel Data Acquisition Systems, Software Defined Radio (SDR) Platform.
Communications Baseband Receiver
The ADC14DC105CISQE/NOPB is a strong fit for dual-channel baseband digitization in software-defined radio (SDR) and LTE/5G small-cell receivers. Its dual simultaneous-sampling 14-bit 105 MSPS channels allow direct I/Q capture from a quadrature demodulator, preserving channel-to-channel phase match critical for demodulation accuracy. The CMOS parallel interface simplifies connection to FPGAs implementing the PHY layer, while the 1.8V supply eases power-rail design. Compared to using two single-channel ADCs, the integrated dual channel reduces board area by ~40% and eliminates inter-channel skew from clock-tree mismatch.

Medical Ultrasound Beamforming
For phased-array ultrasound beamformer front-ends, the ADC14DC105CISQE/NOPB provides the dual simultaneously-sampled 105 MSPS channels needed to capture adjacent transducer element pairs. The 14-bit resolution supports the dynamic range required for diagnostic imaging, while the 60-WFQFN compact footprint enables high-channel-count boards (32/64/128 elements). The CMOS parallel output drives FPGA-based delay-and-sum pipelines at the beamforming stage, with deterministic channel-to-channel phase matching from a shared sample clock reducing calibration burden.

ڈیزائن نوٹس
The exposed thermal pad of the 60-WFQFN package MUST be soldered to a continuous ground copper pour on the top layer, with vias stitching the pad to inner ground planes. This serves both thermal dissipation and provides a low-impedance ground reference for the analog input signal return currents. Recommended thermal via array: at least 9 thermal vias in a 3x3 grid on the pad, with via diameter 0.3 mm and pitch 1.0 mm. Without this stitching, thermal resistance rises above 30 C/W and ground bounce degrades ADC SNR by 2-3 dB.
The ADC14DC105CISQE/NOPB requires separate analog (AVDD) and digital (DVDD/DRVDD) 1.8V supplies. Use a low-noise LDO (such as a TPS7A47 family part) to derive AVDD from a cleaner upstream rail; switching regulator noise on AVDD directly couples into the analog input stage and reduces SNR. Place 10uF + 0.1uF ceramic decoupling pairs as close as possible to each AVDD/DVDD pin, and add a ferrite bead in series with the digital supply to isolate high-frequency switching noise from the analog domain.
Route the analog input traces (AIN1A/AIN1B/AIN2A/AIN2B) as a length-matched differential pair from the input connector or driver to the ADC pins. Keep trace impedance at 100 ohms differential and minimize vias - each via adds ~1 nH of discontinuity that corrupts the input common-mode voltage at frequencies above 30 MHz. The clock traces (CLK+/CLK-) should also be routed as a length-matched differential pair with 100 ohms differential impedance; clock jitter directly translates to ADC aperture uncertainty and degrades SNR.
Do not leave the OEA/OEB output enable pins floating - tie them to logic high or low through 10k resistors to define the output state at power-up. Leaving them floating can cause bus contention with downstream FPGA GPIO during initialization. Also ensure the RST (reset) pin is held low during power-up ramp until the supply rails stabilize; releasing reset before supplies are valid can put the part into an undefined state requiring a power-cycle to recover.
