MAX107ECS+ - Dual 6-Bit 400MSPS ADC | Maxim Integrated
N.º de pieza: MAX107ECS+ ✓ ActivoMAX107ECS+ Descripción general
An ADC is a data-conversion IC that samples an analog voltage and converts it into a digital value. Within the broader semiconductor hierarchy, the MAX107ECS+ is a flash ADC, a data-converter IC, and a high-speed signal-processing component. Flash architectures use a bank of comparators to perform single-cycle parallel conversion, making this device suitable for demanding acquisition stages rather than low-rate precision measurement.
The MAX107ECS+ combines two conversion channels with a 6-bit code width and a maximum sampling rate of 400MSPS. Its on-chip wideband input amplifier reduces the external analog front-end required for many I/Q baseband systems. Demultiplexed differential LVDS outputs support reliable transfer of high-speed digital data between the converter and downstream processing electronics, while parallel output provides an alternative interface architecture.
The manufacturer datasheet identifies the device as a dual 6-bit converter for fast and precise digitizing of in-phase and quadrature baseband signals. Its 400MSPS throughput gives each channel 2.5 ns between ideal sampling intervals. The 6-bit resolution provides 64 digital codes, making the converter particularly useful when system timing, gain, and signal-to-noise performance matter more than fine amplitude quantization.
Typical applications include I/Q baseband digitization, communications receivers, radar signal processing, digital oscilloscopes, spectrum analyzers, and high-speed test equipment. Two integrated channels also support coherent sampling of quadrature signals, allowing one converter to process the in-phase and quadrature channels of a complex baseband waveform.
PCB design should preserve the integrity of the differential LVDS clock and data paths. Place decoupling and analog-input components close to the relevant device pins, maintain the recommended package footprint and exposed-pad soldering pattern, and route high-speed outputs over a continuous reference plane with minimal stubs. Differential impedance and return-path discontinuities can degrade edge quality even when nominal sample-rate and resolution targets are met.
This product page consolidates the MAX107ECS+ electrical characteristics, package details, application guidance, comparison information, and verified sourcing links. It also identifies the distinction between the base MAX107ECS ordering code and the MAX107ECS+ designation, helping engineers verify procurement configuration before PCB release.

Aplicaciones típicas
MAX107ECS+ es adecuado para 6 aplicacións: I/Q Baseband Signal Digitization, Communications Transceiver Baseband, Radar Signal Processing, Digital Oscilloscope Front End, Spectrum Analyzer Acquisition, High-Speed Test and Measurement.
I/Q Baseband Signal Digitization
The MAX107ECS+ fits coherent communications receivers because its two conversion channels can sample in-phase and quadrature baseband signals at up to 400MSPS each. The on-chip wideband input amplifier reduces the amount of analog amplification required immediately before digitization. Demultiplexed differential LVDS outputs can feed FPGA or ASIC logic over a short, controlled interconnect. At the maximum sampling rate, the converter has a 2.5 ns ideal sampling interval, making timing margin and clock distribution central design considerations.
Communications Transceiver Baseband
The MAX107ECS+ is suitable for digitizing wideband I/Q waveforms produced by communication transceivers. Two integrated 6-bit channels provide parallel sampling of complex baseband data, while the 400MSPS maximum rate captures signals with substantially higher bandwidth than a low-speed general-purpose ADC. The LVDS output option supports robust transmission across a controlled PCB interface. System designers should still balance the 6-bit quantization level against receiver gain, filtering, and required signal-to-noise ratio before fixing the front end.
Radar Signal Processing
The MAX107ECS+ can serve as the acquisition converter in radar or high-speed receiver systems that require rapid sampling of complex baseband signals. Its dual-channel architecture supports coherent I/Q measurement, while the integrated wideband input amplifier helps shorten the analog signal path. The 400MSPS rate provides ample sampling speed for many IF or baseband waveforms. Differential LVDS outputs reduce susceptibility to common-mode noise when data is routed to FPGA processing logic, although filtering, gain control, and system timing remain essential.
Digital Oscilloscope Front End
The MAX107ECS+ is applicable to high-speed digital oscilloscope acquisition channels where rapid sampling is more important than fine amplitude resolution. Two channels can capture related waveforms concurrently, while 400MSPS operation supports time-domain analysis of repetitive and transient signals. The 6-bit flash conversion architecture provides fast digital output for FPGA-based processing. A practical implementation still requires careful input attenuation, bandwidth matching, clock jitter control, and verification of the LVDS output timing.
Spectrum Analyzer Acquisition
The MAX107ECS+ can provide the high-speed conversion stage in a spectrum-analyzer or vector-analysis receiver. A 400MSPS sampling rate permits digital capture of wideband intermediate-frequency or complex baseband content, and the dual-channel configuration supports simultaneous I/Q analysis. Differential LVDS outputs are well suited to feeding high-throughput FPGA logic. Designers should account for analog bandwidth, anti-alias filtering, clock quality, and the consequences of using 64 quantization levels when specifying gain and signal levels.
High-Speed Test and Measurement
The MAX107ECS+ fits modular high-speed test equipment in which multiple converters must acquire synchronized signals at a common rate. Its two channels can reduce the number of separate acquisition devices, and the 400MSPS maximum conversion rate supports demanding waveform and modulation tests. The on-chip wideband input amplifier is valuable in compact instrument architectures, while parallel and LVDS output options provide flexibility for different FPGA interfaces. Clock distribution and inter-channel skew should be evaluated carefully in multi-channel systems.

Notas de diseño
Treat the clock, data, and LVDS traces as a controlled high-speed interface. Route differential pairs over a continuous reference plane, minimize stubs and layer transitions, and apply the impedance guidance in the manufacturer datasheet. Keep switching-current paths away from the analog inputs and sensitive clock distribution, because the 400MSPS operating rate leaves little margin for edge degradation or data-bit errors.
Place the input-network, clock, and decoupling components close to their associated MAX107ECS+ pins. Preserve the 80-pin TQFP exposed-pad footprint and its thermal and electrical land pattern exactly. The exposed pad should be connected according to the manufacturer pin-description table and soldering guidance; incorrect treatment can impair heat transfer, grounding, or supply integrity.
Do not assume that every MAX107ECS-family ordering code is a separate electrical substitute. MAX107ECS and MAX107ECS+T are orderable variants within the same converter family, while MAX107ECS+T is identified with a different factory pack quantity. Confirm the complete ordering suffix, package marking, clock requirements, output interface, and exposed-pad connection before approving a substitution.
Información de cumplimiento
The MAX107ECS+ ordering suffix may indicate a specific lead-finish or environmental ordering configuration, but the available technical information does not explicitly state RoHS, REACH, AEC-Q100, halogen-free, or conflict-minerals status.
