MAX1420CCM+TD Übersicht
An ADC (analog-to-digital converter) is a data-conversion integrated circuit that transforms continuous analog voltages into discrete digital codes. Within the data-converter hierarchy, pipelined ADCs like the MAX1420 sit alongside successive-approximation (SAR) and flash converters as the dominant architecture for medium-to-high speed (1 MSPS to 250 MSPS) and 8-to-16-bit resolution requirements. ADCs are themselves a sub-category of data-conversion ICs, which together with DACs, sample-and-hold amplifiers, and references form the signal-chain building blocks inside mixed-signal and instrumentation systems.
Key specifications of the MAX1420CCM+TD include a 60 MSPS sampling rate, 12-bit resolution, fully-differential analog input, internal precision reference, CMOS-compatible three-state parallel outputs with offset-binary coding, and a single 3.3V analog supply. The pipelined architecture and integrated T/H deliver low spurious content and consistent dynamic performance across the Nyquist band, while the internal reference removes the need for an external reference IC and simplifies board layout.
Typical applications include IF/baseband sampling in communications receivers, medical imaging front ends, portable instrumentation, CCD/camera imaging pipelines, and ultrasound systems. In each of these, the combination of 60 MSPS throughput, 12-bit resolution, internal reference, and low-power 3.3V operation provides a compact data-conversion solution without external analog complexity. When designing with this part, observe the input common-mode biasing, drive the analog input in fully-differential fashion for best SFDR, and decouple AVDD/DRVDD with low-ESL ceramics placed within a few millimetres of the supply pins.

Typische Anwendungen
MAX1420CCM+TD ist geeignet für 6 Anwendungs: IF/Baseband Sampling in Communications Receivers, Medical Imaging Front End (Ultrasound, CCD Readout), Portable Test and Measurement Instrumentation, CCD and CMOS Image Sensor Readout Pipelines, Industrial Process-Control Data Acquisition, Software-Defined Radio (SDR) Front End.
IF/Baseband Sampling in Communications Receivers
The MAX1420CCM+TD's 60 MSPS sampling rate and 12-bit resolution make it well-suited for IF and baseband sampling in communications receivers. The fully-differential input and wideband track-and-hold capture modulated signals cleanly, while the internal 2.048 V reference eliminates the need for an external reference IC. Placed between the IF mixer output and an FPGA or DSP demodulator, the ADC delivers 60 MSPS throughput at 3.3 V with low power dissipation, simplifying both baseband DSP chains and software-defined-radio architectures without sacrificing dynamic range.
Empfohlen
Medical Imaging Front End (Ultrasound, CCD Readout)
Medical imaging front ends such as ultrasound beamformers and CCD/camera readout chains rely on ADCs that combine 12-bit dynamic range with 60 MSPS throughput in a compact footprint. The MAX1420CCM+TD's 12-stage pipelined architecture and wideband T/H maintain low spurious content across the Nyquist band, critical for clean image reconstruction. Operating from a single +3.3 V supply with an internal reference, the ADC simplifies power-tree design for portable or cart-based imaging systems while keeping the parallel CMOS output bus easy to interface with image-processing FPGAs.
Empfohlen
Portable Test and Measurement Instrumentation
Portable oscilloscopes, spectrum analysers, and data-acquisition modules benefit from the MAX1420CCM+TD's combination of 60 MSPS sampling, 12-bit resolution, and 3.3 V single-supply operation in a 48-pin TQFP package. The internal reference and CMOS parallel outputs remove external analog complexity, shrinking the BOM for handheld and battery-powered instruments. Differential analog inputs pair with input-protection and gain stages ahead of the ADC, while the three-state outputs simplify bus-sharing with on-board memory or display controllers.
Empfohlen
CCD and CMOS Image Sensor Readout Pipelines
CCD and CMOS image-sensor readout pipelines require ADCs that deliver 12-bit precision at video-rate sampling without adding excessive noise to the analog front end. The MAX1420CCM+TD's pipelined 12-stage architecture and wideband track-and-hold convert sensor analog outputs into offset-binary codes suitable for direct FPGA ingestion. The internal reference and 3.3 V operation ease power and ground-plane layout in dense camera boards, and the parallel CMOS outputs integrate easily with image signal processors (ISPs) for real-time colour-pipeline processing.
Empfohlen
Industrial Process-Control Data Acquisition
Industrial process-control and factory-automation systems digitise sensor outputs such as strain gauges, vibration transducers, and 4-20 mA loop signals for closed-loop control. The MAX1420CCM+TD's 60 MSPS throughput captures fast transient events such as motor inrush or solenoid switching, while 12-bit resolution and the internal precision reference deliver repeatable conversion accuracy across the commercial 0 °C to +70 °C range. Parallel CMOS outputs route directly to industrial PLCs or ARM-based controllers via standard bus interfaces.
Empfohlen
Software-Defined Radio (SDR) Front End
Software-defined radio platforms digitise analogue IF signals as close to the antenna as practical, shifting filtering and demodulation into the digital domain. The MAX1420CCM+TD's 60 MSPS sample rate, fully-differential input, and 12-bit resolution are well-matched to digitising low-IF or zero-IF outputs from a quadrature demodulator in cost-sensitive SDR designs. The internal reference and 3.3 V supply simplify BOM and PCB layout, and the parallel output bus connects directly to FPGA-based baseband processors for software-defined modulation, demodulation, and channelisation.

Wichtigste Unterscheidungsmerkmale
- Internal reference eliminates external reference IC (vs. MAX1420CCM+D (same die, different packaging code))
- Extended industrial temperature drop-in variant available (vs. MAX1420ECM+TD)
- Single +3.3 V supply simplifies power tree (vs. Multi-supply ADCs (e.g., 5 V analog, 3.3 V digital))
Designhinweise
The MAX1420CCM+TD operates from a single +3.3 V supply with separate AVDD and DRVDD pins. Decouple AVDD with a 10 µF tantalum plus a 0.1 µF ceramic placed within 5 mm of the supply pins, and replicate the same network on DRVDD. Sharing AVDD and DRVDD through a single ferrite bead (rather than tying them directly) reduces switching noise coupling from the digital output drivers into the analog front-end at 60 MSPS.
Use a solid analog ground plane under and around the TQFP-48 package. Route the analog input traces as a tightly-coupled differential pair with 50 Ω characteristic impedance on the top layer, and keep digital output bus traces short and away from the analog input to minimise digital-to-analog coupling. Place the input common-mode bias network within a few millimetres of the INP/INN pins.
Driving the MAX1420CCM+TD analog input single-ended rather than fully-differential degrades SFDR and SNR by typically 6-10 dB. Always drive INP and INN as a true differential pair (transformer-coupled or via a differential driver op-amp), and reference both inputs to the internal common-mode voltage. Single-ended drive is not recommended at 60 MSPS.
Compliance-Informationen
RoHS compliant per distributor listings; AEC-Q100 not qualified - choose MAX1420ECM+TD only if extended temperature is needed (industrial, not automotive-qualified).
