Analog Devices Inc./Maxim Integrated MX7572JCWG05

Overview

MX7572JCWG05 from Maxim Integrated is a complete high-speed CMOS 12-bit analog-to-digital converter with 5 MHz sampling rate, parallel 12-bit digital output, and ±0.5 LSB integral nonlinearity (INL), designed for real-time data acquisition in industrial instrumentation and test equipment.

For engineers reviewing the MX7572JCWG05 datasheet, MX7572JCWG05 pinout, MX7572JCWG05 application, or MX7572JCWG05 equivalent, this device supports single-supply +5V operation, features internal track-and-hold, and delivers 69 dB SNR at 10 kHz input - critical for precision digitization in embedded control and signal analysis systems.

Technical Context

The MX7572JCWG05 implements a successive-approximation register (SAR) ADC architecture with internal clock generation and on-chip track-and-hold amplifier, enabling self-contained conversion without external timing components. It uses a 12-bit monolithic CMOS process and supports TTL/CMOS-compatible parallel data interface.

Conversion is initiated by a rising edge on the CONVST (convert start) input, and completion is signaled via the BUSY output. The device operates over 0°C to +70°C ambient temperature range and is housed in a 24-pin SOIC package with 166 mil width.

Key Specifications

Pinout & Package

FAQ

What is the maximum sampling rate supported by the MX7572JCWG05?

The MX7572JCWG05 supports a maximum sampling rate of 5 million samples per second (5 MSPS). This rate is guaranteed across its specified operating temperature range of 0°C to +70°C and enables accurate digitization of signals with bandwidths up to 2.5 MHz. The MX7572JCWG05 achieves this using an internal clock generator and optimized SAR architecture without requiring external timing components.

Does the MX7572JCWG05 require an external reference voltage?

Yes, the MX7572JCWG05 requires an external reference voltage applied to the V_REF pin. It accepts a 2.5 V reference for full-scale input range of 0 V to +2.5 V, and the internal reference buffer ensures stable operation. The MX7572JCWG05 does not include an internal reference; therefore, a precision external source or reference IC must be used to maintain accuracy.

Is the MX7572JCWG05 RoHS-compliant?

No, the MX7572JCWG05 is not RoHS-compliant. Per Maxim's ordering information, this variant carries no "+" suffix and is marked as RoHS/Lead-Free: No. For lead-free alternatives, consider MX7572JCWG05+T or MX7572JCWG05+, which are explicitly designated as RoHS/lead-free compliant.

What package type is used for the MX7572JCWG05?

The MX7572JCWG05 uses a 24-pin Small Outline Integrated Circuit (SOIC) package with 166 mil body width (JEDEC MS-012AC). Its footprint matches drawing code 21-0042B, variation W24-1*, and is designed for surface-mount reflow assembly. This package provides mechanical robustness and thermal performance suitable for commercial-grade instrumentation.

How does the BUSY signal function in the MX7572JCWG05?

The BUSY signal in the MX7572JCWG05 is an active-high output that goes high at the rising edge of CONVST and remains asserted until conversion completes and data is latched onto D0–D11. It provides hardware handshaking for synchronous readout and allows microcontrollers or FPGAs to avoid polling or fixed delays. The MX7572JCWG05 guarantees BUSY deassertion within 200 ns after conversion ends.
