MAX1002CAX+T - 60Msps Dual 6-Bit ADC | Maxim Integrated
MPN: MAX1002CAX+T ✓ פעילMAX1002CAX+T סקירה
An ADC (analog-to-digital converter) is an integrated circuit that converts continuous analog signals into discrete digital codes for downstream DSP, FPGA, or microcontroller processing. As a flash-type pipelined ADC, the MAX1002CAX+T uses parallel comparators to deliver very high conversion rates (up to 60 million samples per second), making it ideal for high-speed signal acquisition. ADCs are a sub-category of data-converter ICs, which themselves sit under the broader umbrella of signal-chain semiconductors alongside DACs, op-amps, and references.
Key specifications include a 60Msps sampling rate, 6-bit resolution, two matched input channels, and a single +5V analog supply. The integrated bandgap voltage reference, matched dual input multiplexers, and TTL-compatible outputs simplify downstream FPGA/CPLD interfacing, eliminating the need for external level shifters. Differential Non-Linearity (DNL) of +/-1/4 LSB and +/-1/4 LSB typical channel-to-channel offset matching preserve signal fidelity.
The MAX1002CAX+T uses a flash conversion front-end followed by a pipelined digital-error-correction back-end, providing 0.1dB gain matching and 0.5-degree phase matching between the two channels. This matched-channel architecture is critical for I/Q signal chains where channel-to-channel mismatch corrupts demodulation accuracy.
Typical applications include IF/baseband digitizing in wireless infrastructure, ultrasound beamforming front-ends, CCD/camera color acquisition, video digitizing, and any simultaneous-sampling dual-channel system. Commercial 0C to +70C operating range targets indoor lab, instrumentation, and embedded-compute systems.
When designing with the MAX1002CAX+T, place a 0.1uF decoupling capacitor within 5mm of the AVDD pin and a 10uF bulk capacitor on the supply rail. Drive the analog inputs with a low-impedance, bandwidth-appropriate front-end op-amp; input bandwidth exceeding 60MHz is recommended to preserve the 60Msps Nyquist band.

יישומים טיפוסיים
MAX1002CAX+T מתאים עבור 6 יישוםs: IF / Baseband Digitizing for Wireless Infrastructure, Ultrasound Beamforming Front-End, CCD / Camera Color Acquisition, Video Digitizing and Frame Grabbers, I/Q Demodulation in Software-Defined Radio, High-Speed Data Acquisition Test Equipment.
IF / Baseband Digitizing for Wireless Infrastructure
The MAX1002CAX+T fits IF and baseband digitizing in wireless infrastructure receivers. The 60Msps sampling rate covers IF bandwidths up to 30MHz while the dual matched channels enable I/Q demodulation of quadrature downconverters directly into the digital domain. With 0.1dB gain match and 0.5-degree phase match between channels, the part preserves image-rejection integrity across the I/Q pair without post-calibration, a common design requirement in cellular and microwave-link base stations. According to the manufacturer datasheet, the +5V single-supply operation simplifies power-tree design in 5V-tolerant FPGA/ASIC front ends, and the TTL-compatible parallel outputs allow direct connection to common FPGA GPIO banks without level translation. Place the MAX1002CAX+T downstream of an IF SAW filter and a broadband op-amp driver such as the AD8138 for a complete IF digitizing channel.
מומלץ
Ultrasound Beamforming Front-End
The MAX1002CAX+T is well suited for ultrasound beamforming front-end digitization. The simultaneous-sampling dual channels sample two transducer elements at exactly the same instant, which is essential for accurate beamforming delay-and-sum math downstream. The 60Msps rate handles probe-center frequencies up to 25MHz with margin for harmonic imaging, while the 6-bit resolution is sufficient for envelope-detected beamformed output stages and low-end B-mode imaging. The matched-channel architecture (0.1dB gain, 0.5-degree phase) minimizes beam-pointing errors across the array. According to the manufacturer datasheet, the 36-SSOP package and single +5V supply enable compact multi-channel boards where 16, 32, or 64 ADCs are tiled into a single beamformer module.
מומלץ
CCD / Camera Color Acquisition
The MAX1002CAX+T suits CCD and CMOS camera color acquisition pipelines. Two matched channels can digitize two of the three RGB color streams simultaneously, simplifying the color-reconstruction pipeline in 3-CCD broadcast cameras and high-end industrial vision systems. The 60Msps rate accommodates standard 1080p video (148.5MHz pixel clock) with two channels paired in parallel, or 720p HD video streams per channel. Per the manufacturer datasheet, the TTL-compatible parallel outputs feed directly into FPGA video-input IP cores, and the internal bandgap reference eliminates external reference components that would otherwise drift with temperature. The commercial 0C to +70C range covers indoor camera-head enclosures.
מומלץ
Video Digitizing and Frame Grabbers
The MAX1002CAX+T serves video digitizing and frame-grabber cards that capture analog composite or component video for archival or processing. The 60Msps rate exceeds the Nyquist requirement for SD (60-pixel) and ED (approx 75-pixel) video bandwidths, and dual channels allow simultaneous Y/C (luma/chroma) capture from S-Video or YPbPr sources without an external multiplexer. According to the manufacturer datasheet, TTL outputs drive standard video FIFO/FPGA pipelines directly. The 36-SSOP footprint is compact enough to integrate into half-height PCI/PCIe frame-grabber boards, where 4-8 channels are typical. The internal bandgap reference avoids drift-induced color-cast issues across the 0C to +70C range.
מומלץ
I/Q Demodulation in Software-Defined Radio
The MAX1002CAX+T fits software-defined radio (SDR) I/Q demodulation stages. The dual matched channels digitize the I and Q baseband outputs of a quadrature demodulator in lockstep, preserving the phase relationship required for accurate modulation recovery. The 0.5-degree typical phase matching minimizes quadrature imbalance that would corrupt constellations in PSK/QAM demodulation, while 0.1dB gain matching preserves symbol-error-rate symmetry. Per the manufacturer datasheet, the 60Msps rate covers signal bandwidths up to 30MHz, fitting HF through L-band SDR receivers. The TTL outputs interface directly to FPGA DSP blocks for downconversion, channelization, and demodulation in a single device.
מומלץ
High-Speed Data Acquisition Test Equipment
The MAX1002CAX+T serves high-speed data acquisition cards in test and measurement equipment such as oscilloscope front-ends, logic-analyzer pattern-generator capture blocks, and bench-instrument IF digitizers. The 60Msps dual-channel rate captures repetitive waveforms with fine horizontal detail, while the matched channels allow true-channel-reference measurements on differential signals. According to the manufacturer datasheet, the +5V supply aligns with legacy bench-instrument power rails, and the TTL parallel bus simplifies interfacing to legacy capture ASICs. The 36-SSOP footprint enables dense multi-channel boards where 4-8 ADCs sit on a single instrument card.

הערות תכנון
The MAX1002CAX+T requires a clean +5V analog supply (AVDD) and a separate digital supply (DVDD). Place a 10uF tantalum bulk capacitor and a 0.1uF ceramic decoupling capacitor within 5mm of each AVDD pin. According to the manufacturer datasheet, the internal bandgap reference requires a 10uF bypass cap on the REF pin; omitting this cap increases noise and harmonic content. Estimated: at 60Msps with TTL output loading, supply current is approximately 80-100mA from AVDD - verify on bench with a current probe before finalizing the power-supply design.
Use a split analog/digital ground plane tied at a single point under the IC. Route analog inputs (INA, INB) and the clock (CLK) as matched-length 50-ohm controlled-impedance traces with ground guard traces on either side. Per Maxim reference designs, the analog input traces should not cross digital output traces; the parallel TTL D0-D5 outputs switch at the clock rate and inject noise into adjacent analog paths. Place the MAX1002CAX+T at least 10mm away from any switching power supply or high-current digital driver.
Do not drive the analog inputs with a high-impedance source above the ADC's specified -3dB input bandwidth (60MHz will exclude the 30MHz Nyquist). Per the manufacturer datasheet, use a low-noise, low-distortion driver op-amp such as the AD8138 with a series resistor network tuned to the ADC's input capacitance. Do not exceed the absolute maximum analog input voltage range; clamp inputs with back-to-back signal diodes if the source can swing beyond AVDD. Failing to bypass the reference pin is the most common cause of degraded SNR in field returns.
