Product details
Overview
MX7572LN05 from Maxim Integrated is a complete high-speed CMOS 12-bit analog-to-digital converter with parallel CPU interface, 5.25 µs conversion time, ±1 LSB integral nonlinearity, and ±0.5 LSB differential nonlinearity - used in real-time data acquisition systems requiring precise digitization of DC-coupled or AC-coupled analog signals.
For engineers reviewing the MX7572LN05 datasheet, MX7572LN05 pinout, MX7572LN05 application, or MX7572LN05 equivalent, this part supports fast 8-bit microprocessor bus timing, features internal track/hold and reference, and delivers stable performance across 0°C to +70°C industrial temperature range without external calibration.
Technical Context
The MX7572LN05 implements a successive-approximation ADC architecture with integrated sample-and-hold amplifier and on-chip 2.5 V reference. It accepts unipolar 0 V to +2.5 V analog inputs and outputs 12-bit parallel digital codes compatible with TTL/CMOS logic levels.
Conversion is initiated by WR pulse and completed within 5.25 µs, with BUSY signal indicating active conversion and RD enabling data readout. The device operates from a single +5 V supply and draws 15 mA typical quiescent current.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 12-bit parallel-output ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX162BCNG | Same 12-bit SAR architecture, but 25 µs conversion time and ±2 LSB INL; requires external reference | Lower speed and reduced accuracy limit use in high-bandwidth control loops | Select when cost sensitivity outweighs speed/accuracy needs and external reference is already present |
| AD7824KNZ | 12-bit, 10 µs conversion, ±0.5 LSB INL, but requires separate +5 V and ±15 V supplies | Higher power and complex supply design preclude use in compact, single-rail embedded systems | Prefer for legacy industrial systems where dual-supply infrastructure exists and tighter INL is mandatory |
Compared with MAX162BCNG and AD7824KNZ, the MX7572LN05 offers the fastest conversion (5.25 µs), best single-supply simplicity (+5 V only), and optimal balance of accuracy (±1 LSB INL) and integration (on-chip reference + S/H) for new commercial-grade DAQ designs.

FAQ
What is the maximum sampling rate supported by the MX7572LN05?
The MX7572LN05 achieves a guaranteed conversion time of 5.25 µs, enabling a theoretical maximum sampling rate of approximately 190 kSPS. This assumes minimal setup/hold overhead on the WR and RD strobes and continuous back-to-back conversion cycles. Real-world throughput in microprocessor-based systems may be lower due to bus arbitration and software latency, but the MX7572LN05 itself imposes no lower limit beyond its 5.25 µs specification.
Does the MX7572LN05 require an external reference voltage?
No, the MX7572LN05 includes an internal 2.5 V reference that supports full-scale 0 V to +2.5 V unipolar analog input operation. VREF can be left unconnected when using the internal reference. However, the pin also accepts an external precision reference (0 V to +2.5 V) for applications demanding higher absolute accuracy or ratiometric measurement against a sensor excitation source.
Is the MX7572LN05 RoHS-compliant?
Yes, the MX7572LN05+ variant is RoHS/lead-free compliant. The base part number MX7572LN05 (without '+' suffix) is not lead-free and uses SnPb terminations. Both versions share identical electrical specifications and package dimensions (PDIP, 24-pin, N24-3* footprint), differing only in finish and compliance status.
Can the MX7572LN05 interface directly with an 8051 microcontroller?
Yes, the MX7572LN05 is fully compatible with the 8051 family. Its WR and RD strobes align with 8051's WR and RD control lines, AD0–AD11 connect directly to P0 (with external pull-ups), and BUSY can be monitored via any GPIO. No glue logic or level shifters are needed, making the MX7572LN05 a drop-in ADC solution for 8051-based data loggers and controllers.
What is the purpose of separate AGND and DGND pins on the MX7572LN05?
The MX7572LN05 uses separate analog ground (AGND) and digital ground (DGND) pins to isolate noise-sensitive analog circuitry (sample-and-hold, comparator) from switching noise generated by the digital output drivers and interface logic. Proper PCB layout-connecting AGND and DGND at a single point near the device and routing analog/digital traces separately-minimizes ground bounce and preserves the specified ±1 LSB INL performance of the MX7572LN05.
