Product details
Overview
MX7572JN12 from Maxim Integrated is a complete high-speed CMOS 12-bit analog-to-digital converter with parallel output, 12.5 MSPS sampling rate, ±0.5 LSB integral nonlinearity (INL), and 69 dB SNR at 100 kHz input - used in real-time digital oscilloscopes and radar signal digitization systems.
For engineers reviewing the MX7572JN12 datasheet, MX7572JN12 pinout, MX7572JN12 application, or MX7572JN12 equivalent, this device supports single +5V supply operation, TTL-compatible parallel data interface, and internal track-and-hold - critical for high-fidelity acquisition in test & measurement and defense electronics.
Technical Context
The MX7572JN12 implements a flash-converter architecture with integrated track-and-hold amplifier and on-chip reference, enabling full-scale conversion without external support circuitry. It features a 24-pin PDIP package with standard 0.3" width and 2.54 mm pitch.
Its timing architecture requires a single external clock (up to 12.5 MHz) to control sampling and data output strobe (OEN), with conversion latency fixed at 1.5 clock cycles. The device operates over 0°C to +70°C and uses unipolar 0 V to +2.5 V input range with internal 2.5 V reference.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 12-bit - delivers 4096 discrete digital codes for precise amplitude quantization of analog signals. |
| Sampling Rate | 12.5 MSPS - supports real-time digitization of baseband signals up to 6.25 MHz (Nyquist-limited). |
| INL | ±0.5 LSB - ensures monotonicity and <0.012% full-scale linearity error across entire transfer function. |
| SNR | 69 dB at 100 kHz - enables >11-bit effective resolution for low-noise signal capture in instrumentation. |
| Supply Voltage | +5 V only - eliminates need for dual supplies or voltage regulators in embedded data acquisition designs. |
| Input Range | 0 V to +2.5 V (unipolar) - matches common sensor output levels and simplifies front-end conditioning. |
| Reference | Internal 2.5 V - removes external reference IC requirement and reduces BOM count and layout area. |
Pinout & Package
MX7572JN12 is housed in a 24-pin plastic dual in-line package (PDIP), 0.3" wide, with 2.54 mm lead pitch and JEDEC MS-001-AC footprint (drawing code N24-3*). Pin 1 is marked by notch or dot; pins are numbered counter-clockwise from top-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VREF) | Reference voltage output | Provides stable 2.5 V internal reference; may be bypassed externally for improved noise immunity. |
| 2–13 (D0–D11) | Parallel data outputs | TTL-compatible 12-bit digital output bus; valid on falling edge of OEN signal. |
| 14 (OEN) | Output enable | Active-low control that gates D0–D11 outputs; allows bus sharing in multi-device systems. |
| 15 (CLK) | Sampling clock input | Accepts TTL/CMOS clock up to 12.5 MHz; initiates sample-and-hold and conversion sequence. |
| 16 (VCC) | Positive supply | +5 V power pin; requires local 0.1 µF ceramic decoupling adjacent to pin. |
| 17 (GND) | Analog ground | Dedicated AGND return for analog section; must be separated from DGND at single-point star ground. |
| 18 (VIN) | Analog input | Unipolar 0 V to +2.5 V differential input; driven directly from op-amp buffer or passive filter. |
| 19 (DGND) | Digital ground | Return path for digital I/O; isolated from AGND except at system-level ground point. |
| 20 (VCC) | Digital supply | +5 V supply shared with analog section; no separate digital rail required. |
| 21 (VREF/ADJ) | Reference adjust | Allows fine-tuning of internal reference via external resistor divider for calibration-critical applications. |
| 22 (VCC) | Additional supply | Third +5 V connection for enhanced power integrity; tied internally to primary VCC. |
| 23 (GND) | Second analog ground | Secondary AGND pin to reduce ground impedance under high-frequency switching conditions. |
| 24 (VCC) | Fourth supply | Fourth +5 V connection; improves decoupling effectiveness across full 24-pin layout. |
Key Features
| Feature | Design Value |
|---|---|
| Monolithic 12-bit ADC with track-and-hold | Eliminates need for external sample-hold amplifier and reduces board space, component count, and timing skew. |
| Single +5 V supply operation | Reduces power subsystem complexity and avoids cross-regulation issues in mixed-signal systems. |
| Internal 2.5 V reference | Removes external reference IC and associated trimming components, lowering cost and improving long-term stability. |
| TTL-compatible parallel interface | Direct connection to microcontroller or FPGA data buses without level-shifting logic or glue logic. |
| 12.5 MSPS throughput with 1.5-cycle latency | Enables deterministic real-time processing pipelines in digital oscilloscopes and burst-mode receivers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed 12-bit ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD7821JRZ | 8-bit resolution, 2 MSPS max, +5 V supply, no internal reference - requires external REF and external track-and-hold. | Suitable for lower-resolution, lower-cost data logging but not for oscilloscope-grade fidelity. | Select when resolution and speed requirements are relaxed and BOM cost is prioritized over performance. |
| MAX1186ETI+ | 12-bit, 40 MSPS, serial LVDS output, +3.3 V supply - higher speed but requires differential signaling and clock/data recovery. | Better for high-density PCBs with FPGA interfaces; incompatible with legacy TTL bus architectures. | Select when system demands >12.5 MSPS and supports LVDS I/O; not drop-in compatible with MX7572JN12 layouts. |
Compared with AD7821JRZ and MAX1186ETI+, the MX7572JN12 offers optimal balance of 12-bit precision, 12.5 MSPS speed, TTL parallel interface, and single-supply simplicity - making it uniquely suited for retrofitting into existing 5 V test equipment and industrial digitizers without redesigning data paths or power rails.

FAQ
What is the maximum sampling rate supported by the MX7572JN12?
The MX7572JN12 supports a maximum sampling rate of 12.5 million samples per second (MSPS). This rate is achieved with a clean 12.5 MHz TTL/CMOS clock applied to the CLK pin. At this rate, the device maintains its specified ±0.5 LSB INL and 69 dB SNR performance, making MX7572JN12 suitable for real-time waveform capture in digital oscilloscopes and radar receivers.
Does the MX7572JN12 require an external reference voltage?
No, the MX7572JN12 includes an internal 2.5 V reference that is sufficient for most applications. Pin 1 (VREF) provides this voltage, and pin 21 (VREF/ADJ) allows optional fine adjustment using an external resistor network. External references are not required unless system-level calibration mandates tighter initial accuracy than the internal reference provides.
What is the operating temperature range of the MX7572JN12?
The MX7572JN12 is rated for commercial temperature operation from 0°C to +70°C. This specification is confirmed in the ordering information table where MX7572JN12 is explicitly listed with "0C to +70C" under Temp. It is not qualified for extended or military temperature ranges.
Is the MX7572JN12 RoHS-compliant?
The MX7572JN12 is not RoHS/lead-free compliant, as indicated in the ordering data where "RoHS/Lead-Free?" is marked "No" for this specific variant. RoHS-compliant alternatives include MX7572JN12+ (with '+' suffix), which uses lead-free finish and meets JEDEC J-STD-609A Class 2 standards.
Can the MX7572JN12 interface directly with a microcontroller's data bus?
Yes, the MX7572JN12 features a TTL-compatible parallel 12-bit output bus (D0–D11) and active-low output enable (OEN), allowing direct connection to 8051, ARM Cortex-M, or other microcontrollers with external memory interfaces. No level shifters or bus transceivers are needed, provided the MCU operates at +5 V and supports asynchronous read timing aligned to OEN deassertion.
