ADC11DL066CIVS/NOPB - Dual 11-Bit 66 MSPS ADC w/450MHz BW | TI
MPN: ADC11DL066CIVS/NOPB ✗ پایان تولیدADC11DL066CIVS/NOPB نمای کلی
An Analog-to-Digital Converter (ADC) is a data-conversion integrated circuit that transforms real-world analog signals into discrete digital codes for processing by DSPs, FPGAs, microcontrollers, or ASICs. ADCs sit in the signal chain between sensors/transducers and digital processors and are critical for defining system-level dynamic range, signal-to-noise ratio (SNR), and effective number of bits (ENOB). The ADC11DL066 belongs to the pipelined ADC sub-class, which uses multiple low-resolution flash stages and a digital correction block to deliver high sampling rates at moderate resolution with relatively low power consumption.
Key features include 66 MSPS sampling rate on each of two simultaneously sampled channels, 450 MHz analog input bandwidth for undersampling IF/RF signals, internal 1.0 V reference (with option for external reference), CMOS-compatible digital outputs, and a 3.3 V single-supply operation. The pipelined architecture delivers 7.5 effective bits typical at Nyquist and supports full-power input bandwidth beyond the second Nyquist zone.
The ADC11DL066 employs a fully differential pipelined architecture with per-stage MDAC and flash sub-ADC, internally trimmed gain and offset, and an on-chip bandgap reference. Its input stage uses a switched-capacitor sample-and-hold with a wideband input buffer, supporting both AC- and DC-coupled single-ended or differential drive networks. The internal reference can be bypassed to share an external precision reference across multiple converters for gain-matched multi-channel systems.
Typical applications include IF/baseband digitization in wireless infrastructure, medical ultrasound beamformers, portable test and measurement instrumentation, digital oscilloscopes and spectrum analyzers, dual-antenna diversity receivers, and CCD imaging front-ends. The dual simultaneous-sampling channels make it especially well-suited to I/Q demodulation and multichannel data acquisition.
When designing with this device, keep input traces short and use a differential drive network with 50 ohm terminations to preserve the 450 MHz input bandwidth. Provide low-impedance analog and digital supply planes, decouple close to each supply pin, and route LVCMOS outputs away from analog inputs to minimize digital coupling into the sample-and-hold. With sample rates beyond ~40 MSPS, a thermal estimate using the datasheet's typical power figure is recommended to size the PCB copper area; the 64-TQFP is a thermally enhanced package with an exposed-style pad path on the lead frame.

کاربردهای معمول
ADC11DL066CIVS/NOPB مناسب است برای 6 کاربردs: IF and Baseband Digitization in Wireless Receivers, Medical Ultrasound Beamforming Front-End, Portable Test and Measurement Instrumentation, Multi-Channel Data Acquisition Systems, Digital Oscilloscope and Spectrum Analyzer Front-End, CCD and Image Sensor Front-End Digitization.
IF and Baseband Digitization in Wireless Receivers
The ADC11DL066CIVS/NOPB's 450 MHz analog input bandwidth and 66 MSPS per channel support direct IF sampling at second- and third-Nyquist zones, eliminating an analog downconversion stage in receiver lineups. With 11-bit resolution and dual simultaneous channels, the device performs I/Q demodulation for SDR and diversity receivers while maintaining 7.5 effective bits typical at Nyquist. Designers typically place the part downstream of an anti-alias bandpass filter and feed it from a differential balun; unlike wider-input ADCs the 11-bit pipeline keeps per-channel power dissipation manageable in multi-channel antenna arrays.

Medical Ultrasound Beamforming Front-End
Dual simultaneous sampling at 66 MSPS with matched gain per channel makes the ADC11DL066CIVS/NOPB a strong fit for ultrasound beamformers, which require time-aligned channels across dozens of transducers. The integrated 1.0 V reference is shared across channels in array applications to keep gain drift correlated; the 450 MHz input bandwidth comfortably captures transducer harmonics up to the 6th or 7th band. The pipelined architecture delivers the throughput needed for real-time imaging while keeping per-channel power low enough to permit dense PCB placement in probe-head assemblies.
پیشنهادی
Portable Test and Measurement Instrumentation
Handheld oscilloscopes, spectrum analyzers, and signal analyzers benefit from the ADC11DL066CIVS/NOPB's 450 MHz input bandwidth and parallel CMOS output bus, which feeds an FPGA for DDC/FFT processing. Two channels enable simultaneous stimulus-and-response capture without external sample-mux switching, and the 3.3 V supply simplifies battery-isolated front-end design. Compared with higher-resolution pipeline ADCs, the 11-bit pipeline keeps the BOM cost low while preserving enough ENOB for sub-100 MHz measurements common in field-portable instruments.
پیشنهادی
Multi-Channel Data Acquisition Systems
The dual 66 MSPS channels of the ADC11DL066CIVS/NOPB map directly onto multi-channel DAS boards serving industrial vibration, sonar, and rotating-machine monitoring. The internal reference eliminates one external IC per channel, and the parallel LVCMOS output bus supports simultaneous read-out to an FPGA without serializer deserialization overhead. Industrial users should note the -40C to +85C qualification, well within typical control-room and outdoor-enclosure envelopes; the TQFP-64 footprint gives ~1.6 mm pad pitch for hand-rework-friendly prototypes.
پیشنهادی
Digital Oscilloscope and Spectrum Analyzer Front-End
The ADC11DL066CIVS/NOPB's 450 MHz analog input bandwidth directly supports 100 MHz+ real-time oscilloscope front-ends and HF spectrum analyzer IF chains. Two parallel channels let compact bench instruments support both scope and logic-like channels without doubling the BOM. Sub-Nyquist alias rejection is delivered by the board-level 5th-order Butterworth anti-alias filter driving the ADC's differential inputs; designers should budget ~3.5 ENOB for the front-end pipeline to retain usable dynamic range at full input bandwidth.
پیشنهادی
CCD and Image Sensor Front-End Digitization
The dual differential inputs of the ADC11DL066CIVS/NOPB accept correlated-double-sampled CCD outputs for digitizing image-sensor analog front-ends, where small signals near 1 V must be captured at clock-related sample instants. The 66 MSPS per-channel throughput suits VGA-grade sensor read rates and lower-resolution HD sensor streams. The internal 1.0 V reference is shared across channels to keep dark-current calibration baseline constant across the imaging array; PCB designers should pair the ADC with a quiet LDO such as the TPS7A4701 to drive AVDD and minimize spurious noise coupled into the sample-and-hold.

یادداشت‌های طراحی
Place the ADC11DL066CIVS/NOPB within 5 mm of its anti-alias bandpass filter and balun, using a differential microstrip pair with 50 ohm characteristic impedance. Decouple each AVDD pin with a 100 nF X7R plus a 10 uF tantalum bulk cap within 2 mm of the pin, and place a small ferrite between AVDD and the LDO output to isolate switching noise from the sample-and-hold.
Route the 11-bit parallel CMOS data bus to the FPGA with matched-length traces (within +/- 2 mm) and a 30-50 ohm series damping resistor near the ADC outputs to suppress ringing. Keep the digital bus on the opposite PCB layer from the analog inputs, separated by a continuous ground plane so that digital-coupling return currents cannot leak into the analog front-end.
Estimated power dissipation at 66 MSPS full-rate, single 3.3 V supply, both channels active and 450 MHz input: plan for ~3.0 mW per MSPS per channel per the family datasheet. Size the PCB copper area under and around the TQFP-64 to keep junction rise under ~20 C; if a multi-board stack houses more than 4 ADCs, add a small aluminum heat-spreader or dedicated airflow path.
