Product details
Overview
MX7572JEWG05 from Maxim Integrated is a complete high-speed CMOS 12-bit analog-to-digital converter with parallel interface, 5.25 MSPS sampling rate, ±0.5 LSB integral nonlinearity, and SOIC-24 package rated for –40°C to +85°C operation. It serves as a precision data acquisition front-end in real-time instrumentation and digital oscilloscope signal chains.
For engineers reviewing the MX7572JEWG05 datasheet, MX7572JEWG05 pinout, MX7572JEWG05 application, or MX7572JEWG05 equivalent, key selection criteria include its 12-bit resolution, 5.25 MSPS throughput, single-supply 5V operation, internal track-and-hold, and compatibility with TTL/CMOS logic levels.
Technical Context
The MX7572JEWG05 implements a successive approximation register (SAR) architecture with an integrated track-and-hold amplifier and reference buffer. It requires no external clock divider and accepts a single 5V supply, simplifying system power design.
Its parallel 12-bit data bus outputs are latched on the falling edge of /RD, supporting direct interfacing to microcontrollers and FPGAs without glue logic. Conversion initiation is controlled via the /CONVST input, enabling precise timing synchronization in multi-channel systems.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 12-bit SAR ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX1166BCAP+ | 16-bit, 250 kSPS, SPI interface, internal reference; lower speed, higher resolution, serial interface | Suitable for low-speed precision sensing (e.g., strain gauges), not real-time waveform capture | Select when resolution > speed and serial interface simplifies routing |
| ADS7822U | 12-bit, 200 kSPS, SPI interface, external reference; slower, no internal ref, smaller SO-8 package | Fits space-constrained designs where throughput ≤200 kSPS suffices (e.g., sensor hubs) | Select for ultra-compact layouts and lower power, accepting reduced speed |
Compared with MAX1166BCAP+ and ADS7822U, the MX7572JEWG05 uniquely balances 12-bit precision, 5.25 MSPS parallel throughput, and single-supply operation-making it optimal for real-time digitization where speed, simplicity, and industrial reliability converge.

FAQ
What is the maximum sampling rate supported by the MX7572JEWG05?
The MX7572JEWG05 supports a maximum sampling rate of 5.25 million samples per second (MSPS). This rate is achieved using its internal clock and is specified across the full –40°C to +85°C operating temperature range. The MX7572JEWG05 maintains this throughput without external clock dividers or timing adjustments, making it suitable for real-time waveform digitization in test and measurement applications.
Does the MX7572JEWG05 require an external reference voltage?
No, the MX7572JEWG05 does not require an external reference voltage. It includes an internal 2.5V reference with ±0.5% initial accuracy and 25 ppm/°C temperature drift, accessible via the REFIN/REFOUT pin. This integrated reference eliminates the need for external precision references in most applications, though the device also supports external 2.5V references if higher accuracy or custom scaling is needed.
What logic family is compatible with the MX7572JEWG05's digital interface?
The MX7572JEWG05's DB0–DB11 outputs and control inputs (/CONVST, /RD) are fully compatible with standard TTL and CMOS logic families operating at +5V. Its outputs meet VOH ≥ 2.4V and VOL ≤ 0.4V specifications under load, ensuring reliable interfacing with 8051 derivatives, legacy microcontrollers, and FPGA I/O banks configured for 5V-tolerant operation.
Is the MX7572JEWG05 RoHS-compliant?
The MX7572JEWG05 is not RoHS/lead-free compliant, as indicated by its absence of "+" suffix and explicit "RoHS/Lead-Free: No" designation in Maxim's official ordering information. It uses leaded solder terminations and conforms to legacy industrial standards where Pb-based finishes remain acceptable. For RoHS-compliant alternatives, consider MX7572JEWG05+T or MX7572JEWG05+ variants.
How is conversion timing controlled on the MX7572JEWG05?
Conversion timing on the MX7572JEWG05 is controlled by two dedicated signals: /CONVST initiates conversion on its falling edge, and /RD latches the 12-bit result onto the data bus on its falling edge. The /BUSY pin goes high during conversion and returns low when data is ready, enabling either polling or interrupt-driven readout. This deterministic timing allows tight synchronization with host processors in real-time systems.
