Product details
Overview
MX7572KCWG05 from Maxim Integrated is a complete high-speed CMOS 12-bit analog-to-digital converter with parallel CPU interface, 500 ksps sampling rate, and ±1 LSB integral nonlinearity (INL), designed for real-time data acquisition in industrial instrumentation and test equipment.
For engineers reviewing the MX7572KCWG05 datasheet, MX7572KCWG05 pinout, MX7572KCWG05 application, or MX7572KCWG05 equivalent, this device requires attention to its 24-pin SOIC package, single +5V supply operation, internal reference, and TTL/CMOS-compatible digital interface timing.
Technical Context
The MX7572KCWG05 implements a successive-approximation register (SAR) ADC architecture with internal track-and-hold and reference, enabling conversion without external support circuitry. It features a parallel 12-bit digital output bus and uses a 500 kHz maximum clock input for timing control.
Its conversion cycle completes in 2 µs, with aperture jitter under 10 ps, and supports both continuous and single-shot conversion modes via the CONVST and RD control signals. The device operates over 0°C to +70°C and is specified with ±1 LSB differential nonlinearity (DNL) and no missing codes.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| INL | ±1 LSB - ensures end-point linearity within 0.024% of full scale for calibration-sensitive applications |
| DNL | ±1 LSB - guarantees monotonic response and absence of missing codes across full range |
| Supply Voltage | +5V only - simplifies power design with single-rail operation, no dual or analog/digital split supplies |
| Reference | Internal 2.5V - eliminates need for external voltage reference component and associated layout complexity |
| Aperture Jitter | <10 ps - enables accurate digitization of high-frequency analog inputs without added sampling uncertainty |

| CLK | Master Clock Input | Accepts 500 kHz max clock for internal timing; determines conversion duration (2 µs cycle) |
| VREF | Reference Voltage Pin | Internally tied to 2.5V reference; externally accessible for monitoring or optional override |
| AGND / DGND | Analog & Digital Ground | Separate ground pins require star-point connection to minimize digital noise coupling into analog path |
Key Features

IC Role / Device Role / Timing Role: Standalone ADC in fixture-mounted measurement channel, triggered by ATE controller via CONVST/RD handshake. Use Value: Internal 2.5V reference provides stable, repeatable measurement baseline; no missing codes prevents false fail during pass/fail thresholding. |
| Medical Patient Monitors | Power Quality Analyzers |
|
Use Scenario: Digitizing ECG, respiration, or blood pressure waveforms in portable bedside monitors operating on battery power. IC Role / Device Role / Timing Role: Low-power, single-supply ADC interfaced directly to microcontroller's parallel port for waveform capture at ≤1 ksps. Use Value: Single +5V operation reduces power conversion stages; 10 ps aperture jitter preserves waveform fidelity critical for arrhythmia detection. |

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 |
|---|---|---|---|
| AD7892BRZ-5 | 5 V supply, 500 ksps, ±1 LSB INL, but requires external reference and separate AVDD/DVDD rails | Higher layout complexity due to dual supply and reference decoupling requirements | Select when system already includes precision external reference and split-rail power architecture |
| MAX1166BCAP+ | 12-bit, 250 ksps, internal reference, single +3.3V supply - slower, lower voltage, different pinout | Not suitable for 5V CPU bus interfaces; requires level translation or 3.3V host | Choose only for new low-voltage designs where reduced power and smaller QFN package outweigh speed loss |
Compared with AD7892BRZ-5 and MAX1166BCAP+, the MX7572KCWG05 uniquely combines 500 ksps speed, internal 2.5V reference, and true 5V-tolerant parallel interface in a single SOIC package - simplifying design while maintaining metrology-grade linearity.

FAQ
What is the maximum clock frequency supported by the MX7572KCWG05?
The MX7572KCWG05 accepts a maximum clock input frequency of 500 kHz, which defines its 2 µs conversion cycle time. Exceeding this frequency may cause timing violations, incomplete conversions, or invalid digital output. The MX7572KCWG05 datasheet specifies strict setup/hold timing relative to CLK edges, and all timing diagrams assume operation within this limit.
Does the MX7572KCWG05 require an external voltage reference?
No, the MX7572KCWG05 includes an internal 2.5V reference that is factory-trimmed and temperature-compensated. This reference is accessible at the VREF pin and can be used directly or buffered for external circuits. Using the internal reference eliminates the need for external components and improves system-level accuracy stability over temperature for the MX7572KCWG05.
Is the MX7572KCWG05 compatible with 3.3V logic interfaces?
No, the MX7572KCWG05 digital interface is fully TTL/CMOS-compatible but designed for 5V operation: its DB0–DB11 outputs swing rail-to-rail between 0V and VCC (5V), and input thresholds are referenced to 5V logic levels. Direct connection to 3.3V-only hosts risks overvoltage damage or unreliable reads; level-shifting circuitry is required for interoperability with the MX7572KCWG05.
What is the operating temperature range of the MX7572KCWG05?
The MX7572KCWG05 is rated for commercial temperature operation from 0°C to +70°C. This range is explicitly defined in Maxim's ordering information and applies to all variants with the "K" grade suffix (e.g., MX7572KCWG05, MX7572KCWG12). Industrial-grade alternatives such as MX7572KEWG05 extend operation to –40°C to +85°C but use different suffixes and packaging.
How does the MX7572KCWG05 handle analog input voltage range?
The MX7572KCWG05 accepts a unipolar analog input range of 0V to +2.5V when using the internal reference. With external reference applied to VREF, the full-scale input becomes 0V to VREF. The device does not support bipolar input configurations or input ranges exceeding VREF; exceeding 2.5V on the analog input with internal reference risks saturation or clipping, directly impacting measurement integrity of the MX7572KCWG05.
