Product details
Overview
MX7572KN05 from Maxim Integrated is a complete high-speed CMOS 12-bit analog-to-digital converter with 500 ksps sampling rate, ±1 LSB integral nonlinearity (INL), and parallel 8-bit data output interface. It operates from a single +5V supply and is used in real-time waveform digitization for test equipment and industrial data acquisition systems.
For engineers reviewing the MX7572KN05 datasheet, MX7572KN05 pinout, MX7572KN05 application, or MX7572KN05 equivalent, this device supports fast parallel interfacing to microcontrollers and FPGAs in embedded measurement systems requiring 12-bit resolution at moderate speed without external reference or clock conditioning.
Technical Context
The MX7572KN05 implements a successive-approximation register (SAR) architecture with internal sample-and-hold and reference buffer. It accepts unipolar 0V to +5V analog input and delivers 12-bit digital output via an 8-bit multiplexed bus with separate most-significant and least-significant byte strobes (MSB/LSB).
Timing is controlled by a single external clock (CLK) input, with conversion initiated by CONVST and completed within 2 µs. The device requires no external components for basic operation and features TTL-compatible digital I/O with 24-pin PDIP package footprint compatibility across the MX7572 family.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 12-bit - provides 4096 discrete output levels for precise amplitude quantization of analog signals. |
| Sampling Rate | 500 ksps - enables capture of signals up to 250 kHz (Nyquist-limited) in continuous acquisition mode. |
| INL | ±1 LSB - ensures monotonicity and minimal code-width variation across full-scale range. |
| Supply Voltage | +5V only - simplifies power design with single-rail operation and no negative or auxiliary supplies required. |
| Analog Input Range | 0V to +5V (unipolar) - directly interfaces with standard DAC outputs and sensor signal chains referenced to ground. |
| Digital Interface | 8-bit multiplexed parallel bus with MSB/LSB strobes - reduces PCB trace count while maintaining full 12-bit throughput. |
| Operating Temperature | 0°C to +70°C - qualified for commercial-grade applications including benchtop instrumentation and factory-floor controllers. |
| Package | 24-pin PDIP (N24-3*) - compatible with through-hole prototyping and legacy automated insertion equipment. |
Pinout & Package
MX7572KN05 is housed in a 24-pin plastic dual in-line package (PDIP) per drawing 21-0043D, with 0.3-inch body width and standard 0.1-inch pin pitch. The package supports hand-soldering, socketing, and wave soldering with lead-free finish optional (MX7572KN05+ variant).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4, 5, 6, 7, 8 | Data Output (D0–D7) | Multiplexed 8-bit bus delivering LSB first, then MSB; requires external latch control for full 12-bit capture. |
| 9 | CONVST | Active-low conversion start trigger; initiates sample-and-hold and SAR cycle on falling edge. |
| 10 | CLK | External clock input (max 2 MHz); defines conversion timing and internal logic synchronization. |
| 11 | EOC | End-of-conversion flag (active-high pulse); signals completion and readiness of output data. |
| 12 | VREF | Internal reference voltage output (4.096V); may be used as precision reference for external circuitry. |
| 13 | AGND | Analog ground - must be isolated from digital ground at single-point connection to minimize noise coupling. |
| 14 | ANALOG IN | Unipolar analog input (0V to +5V); accepts DC or AC-coupled signals with proper biasing. |
| 15 | DGND | Digital ground - return path for all digital I/O and internal logic; ties to system digital plane. |
| 16 | VCC | +5V supply - powers both analog and digital sections; requires local 0.1 µF ceramic bypass capacitor. |
| 17, 18 | MSB/LSB | Byte-select strobes - indicate valid MSB or LSB on D0–D7 bus; used to latch respective byte into external registers. |
| 19–24 | No Connect | Unused pins - left unconnected per datasheet; no internal connection or function. |
Key Features
| Feature | Design Value |
|---|---|
| Complete ADC subsystem | Integrates sample-and-hold, reference, and SAR core - eliminates need for external support components in basic configurations. |

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 |
|---|---|---|---|
| MAX162BCNG | Same 12-bit SAR architecture, but rated for 0°C to +70°C and uses identical 24-pin PDIP (N24-3*); differs in internal reference tolerance (±0.5% vs MX7572KN05's ±0.2%). | Designed for general-purpose data acquisition where tighter reference drift is not critical. | Select MAX162BCNG when reference stability beyond ±0.5% is acceptable and legacy MAX162 board layouts are reused. |
| AD7892BN-3 | 12-bit SAR ADC with 500 ksps, but requires dual ±5V supplies and separate external reference; no on-chip VREF output. | Suitable for systems already using bipolar supplies and where reference flexibility outweighs integration benefits. | Choose AD7892BN-3 only if existing power architecture supports ±5V and external reference selection is preferred for system-level calibration. |
Compared with MAX162BCNG and AD7892BN-3, MX7572KN05 offers superior integration (on-chip 4.096V reference, single +5V supply) and lower system component count, making it optimal for cost-sensitive, space-constrained commercial instrumentation where unipolar 0V–5V input range suffices.

FAQ
What is the maximum sampling rate supported by the MX7572KN05?
The MX7572KN05 supports a maximum sampling rate of 500 ksps, achieved with a 2 MHz external clock and confirmed conversion time of 2 µs per sample. This rate is guaranteed across the full 0°C to +70°C operating temperature range and under standard +5V supply conditions specified in the datasheet.
Does the MX7572KN05 require an external reference voltage?
No, the MX7572KN05 does not require an external reference voltage. It includes an internal temperature-compensated 4.096V reference (VREF) that serves both the ADC core and can be used externally. The device is fully functional with only a +5V supply and no additional reference components.
What package type and pin count does the MX7572KN05 use?
The MX7572KN05 uses a 24-pin plastic dual in-line package (PDIP) with footprint code N24-3*, matching drawing 21-0043D. It is a through-hole package with 0.3-inch body width and 0.1-inch pin spacing, designed for compatibility with legacy PCB layouts and manual or wave soldering processes.
Is the MX7572KN05 RoHS-compliant?
The standard MX7572KN05 is not RoHS/lead-free compliant, as indicated in the official ordering information. However, the RoHS-compliant version is available as MX7572KN05+, which uses the same N24+3* package variant and maintains identical electrical specifications and timing behavior.
How is 12-bit data transferred from the MX7572KN05 given its 8-bit output bus?
The MX7572KN05 transfers 12-bit data via an 8-bit multiplexed bus: the least-significant byte (LSB) appears first on D0–D7, strobed by the LSB pin, followed by the most-significant byte (MSB) on the same bus, strobed by the MSB pin. External latches or microcontroller firmware must capture and combine the two bytes to reconstruct the full 12-bit word.
