Product details
Overview
MAX19506ETM+ from Maxim Integrated is a dual-channel, 8-bit analog-to-digital converter (ADC) with 100Msps sampling rate, 49.8dBFS SNR at 70MHz, 69dBc SFDR at 70MHz, and 850MHz full-power bandwidth. It operates from 1.8V analog supply or 2.5V–3.3V regulated AVDD, supports DC-coupled RF/IF inputs via 0.4V–1.4V common-mode range, and targets zero-IF receivers in cellular base stations.
For engineers reviewing the MAX19506ETM+ datasheet, MAX19506ETM+ pinout, MAX19506ETM+ application, or MAX19506ETM+ equivalent, this page delivers verified electrical specs, validated dual-CMOS/multiplexed output timing, confirmed 48-pin TQFN package mapping, and real-world interface constraints for high-speed data acquisition systems.
Technical Context
The MAX19506ETM+ employs a 10-stage fully differential pipelined architecture with 9-cycle latency, digital error correction to eliminate missing codes, and self-biased differential clock inputs supporting 50MHz–100MHz operation. Its track-and-hold circuit uses 120Ω switch resistance and 1.2pF sampled capacitance per input.
It integrates programmable common-mode reference (0.45V–1.35V in 0.15V steps), selectable clock division (DIV1/DIV2/DIV4), dual or multiplexed CMOS output buses, and configurable data formats (two's complement, gray code, offset binary) accessed via SPI or parallel control mode.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 8-bit - defines quantization step size and dynamic range for digitizing analog signals in communications front-ends. |
| Max Sampling Rate | 100Msps - enables Nyquist-compliant digitization of IF signals up to 50MHz without aliasing in ZIF architectures. |
| SNR @ 70MHz | 49.8dBFS - determines minimum detectable signal level above quantization and thermal noise floor in receiver chains. |
| SFDR @ 70MHz | 69dBc - specifies spurious-free operating range for multi-tone signals in microwave receivers and ultrasound imaging. |
| Input Bandwidth | 850MHz - supports wideband RF sampling beyond L-band, critical for direct-conversion transceivers and spectrum analyzers. |
| Common-Mode Range | 0.4V to 1.4V - allows seamless DC coupling to transformer-coupled or active balun-based front-ends without external bias networks. |
| Analog Supply | 1.8V or 2.5V–3.3V (regulator mode) - provides flexibility in mixed-supply systems while maintaining low power consumption per channel. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel, 8-bit, high-speed ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX19505ETM+ | Same 48-pin TQFN package and pinout; 65Msps max sample rate; identical 8-bit resolution and 0.4V–1.4V common-mode range. | Lower power (37mW/channel) but insufficient for 100Msps ZIF sampling; suitable for cost-sensitive IF digitization below 32.5MHz Nyquist zone. | Select MAX19505ETM+ when system clock budget limits sampling rate and SNR >48dBFS remains acceptable at lower frequencies. |

FAQ
What is the maximum sampling rate supported by the MAX19506ETM+?
The MAX19506ETM+ supports a maximum sampling rate of 100Msps, validated across the full -40°C to +85°C temperature range with typical SNR of 49.8dBFS and SFDR of 69dBc at 70MHz input frequency. This rate is sustained using either differential or single-ended clock inputs with 50MHz–100MHz frequency range.
Does the MAX19506ETM+ support DC-coupled analog inputs?
Yes, the MAX19506ETM+ supports DC-coupled analog inputs via its wide 0.4V to 1.4V programmable common-mode voltage range. Internal 2kΩ resistors can be enabled through SPI registers to supply bias current, and the common-mode reference (CMA/CMB) is adjustable from 0.45V to 1.35V in 0.15V steps - enabling direct connection to transformerless RF amplifiers.
What package type and pin count does the MAX19506ETM+ use?
The MAX19506ETM+ is packaged in a 7mm × 7mm, 48-pin thin QFN with exposed pad (TQFN-EP), specified for operation from -40°C to +85°C. Pin functions include dual 8-bit CMOS outputs (D0A–D7A, D0B–D7B), differential clock inputs (CLK+/CLK-), and dedicated data clocks (DCLKA/DCLKB), all mapped in the official Maxim pin configuration diagram.
Can the MAX19506ETM+ operate from a single 1.8V supply?
Yes, the MAX19506ETM+ operates from a 1.8V analog supply (AVDD) for core conversion circuitry, while digital outputs run on an independent OVDD supply from 1.8V to 3.5V. An integrated self-sensing regulator also allows AVDD to be supplied from 2.5V–3.3V, simplifying power architecture in mixed-voltage systems without external regulators.
How is the MAX19506ETM+ programmed for different output configurations?
The MAX19506ETM+ is programmed via a 3-wire SPI interface (CS, SCLK, SDIN) when SPEN is low, enabling full register control over output format (two's complement/gray/offset binary), clock division (DIV1/DIV2/DIV4), and common-mode voltage. When SPEN is high, those pins become parallel controls for bus mode, format, and divider selection - eliminating need for microcontroller firmware in fixed-function designs.
