Product details
Overview
MX7572JN05 from Maxim Integrated is a complete high-speed CMOS 12-bit analog-to-digital converter with 5.25 MSPS sampling rate, ±0.5 LSB integral nonlinearity (INL), 69.5 dB SNR, and single +5V supply operation. It integrates internal track-and-hold, reference, and parallel digital output, and is used in real-time waveform digitization for test equipment and high-fidelity data acquisition systems.
For engineers reviewing the MX7572JN05 datasheet, MX7572JN05 pinout, MX7572JN05 application, or MX7572JN05 equivalent, key selection considerations include its 5.25 MSPS throughput, 12-bit resolution with guaranteed monotonicity, single-supply compatibility, and PDIP-24 package suitability for prototyping and legacy industrial designs.
Technical Context
The MX7572JN05 implements a flash-based architecture with internal 2.5V reference and on-chip track-and-hold amplifier, enabling full-scale conversion without external support circuitry. Its parallel CMOS-compatible output interface drives standard TTL/CMOS logic directly at up to 5.25 MHz.
Designed for DC-coupled signal chains, it features differential input structure with ±2.5V full-scale range (unipolar/bipolar selectable via REF pin), 10 ns aperture jitter, and guaranteed 12-bit accuracy over 0°C to +70°C ambient temperature range.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 12-bit, medium-speed ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX162BCNG | Same 12-bit resolution, but 1 MSPS max sampling rate and higher ±1.5 LSB INL | Lower speed suits slower control loops or low-bandwidth sensor interfaces | Select when cost sensitivity outweighs throughput requirements and layout space allows SOIC or PDIP variants |
| AD7821KNZ | 12-bit, 2.5 MSPS, ±1 LSB INL, requires external reference and separate analog/digital supplies | Higher power and board area needed due to external support components | Prefer when existing designs already use ADI's reference ecosystem or require tighter thermal drift specs |
Compared with MAX162BCNG and AD7821KNZ, MX7572JN05 offers the highest throughput among PDIP-packaged 12-bit ADCs with integrated reference and single-supply operation, making it optimal for space-constrained, high-sample-rate instrumentation where layout simplicity is prioritized.

FAQ
What is the maximum sampling rate supported by MX7572JN05?
The MX7572JN05 supports a maximum sampling rate of 5.25 million samples per second (MSPS), achieved when driven by a minimum 5.25 MHz master clock. This rate is guaranteed across the full 0°C to +70°C operating temperature range and enables accurate digitization of signals with bandwidths up to approximately 2.6 MHz under Nyquist criteria. The MX7572JN05 maintains specified INL and SNR performance at this maximum rate.
Does MX7572JN05 require an external reference voltage?
No, MX7572JN05 includes a precision internal 2.5V reference and does not require an external reference for standard operation. The REF pin selects between ±2.5V differential and 0V to +5V unipolar input ranges, while EXT/INT pin configures internal reference usage. External reference can be applied only if EXT/INT is grounded, but this mode is not supported in the MX7572JN05's default configuration per its datasheet specifications.
Is MX7572JN05 RoHS compliant?
MX7572JN05 is not RoHS/lead-free compliant, as indicated by its part number suffix "JN05" (no '+' symbol) and confirmed in Maxim's ordering information table. It uses leaded solder terminations and falls under RoHS exemption categories applicable to high-reliability analog components manufactured prior to full RoHS transition. For RoHS-compliant alternatives, consider MX7572JN05+ or SOIC-packaged variants with '+' suffix.
What package type is used for MX7572JN05?
MX7572JN05 uses a 24-pin plastic dual in-line package (PDIP) with 0.3-inch body width and 2.54 mm pin pitch, per Maxim drawing code N24-3 (document 21-0043D). This through-hole package supports manual assembly, socketing for burn-in or rework, and compatibility with legacy test equipment PCBs originally designed for similar ADCs such as the AD7820 or MAX162 series.
How is the input range configured on MX7572JN05?
The MX7572JN05 supports two input ranges: ±2.5V differential (bipolar) and 0V to +5V (unipolar), selected via the REF pin. When REF is tied to VCC, the device operates in ±2.5V mode; when REF is grounded, it switches to 0V to +5V mode. The differential input structure (IN+, IN−) remains active in both configurations, and common-mode voltage is internally biased to mid-supply regardless of range selection. This configuration is fixed at power-up and does not require dynamic control.
