典型應用
MAX113CNG+ 適用於 6 應用s: Industrial Process Control, Instrumentation Panel, Battery-Powered Monitoring, Threshold and Limit Control, Educational and Legacy Test Equipment, Data Acquisition Backplane.
Industrial Process Control
The MAX113CNG+ fits legacy industrial process-control systems that must monitor four proportional analog inputs while retaining a microprocessor-compatible parallel interface. Its 8-bit resolution provides 256 quantization levels for thresholding and supervisory control, while the 400 ksps conversion rate supports rapid sequential sampling. The single +3 V supply simplifies connection to 3.3 V controller hardware, and the 1 uA power-down current is useful when the controller periodically wakes for measurement. Designers should verify analog input range, reference accuracy, settling time, and isolation requirements from the manufacturer datasheet. Because the device is obsolete, new production designs should also evaluate an active converter with higher resolution and a more compact package.
推薦
Instrumentation Panel
The MAX113CNG+ can support instrumentation panels that acquire up to four sensor or control signals and present their values through a parallel digital bus. At 400 ksps and 1.8 us per conversion, it can service rapidly changing inputs, while the four-channel architecture reduces the number of converters needed for coordinated measurements. The 8-bit result is sufficient for display positioning, coarse status indication, and simple alarm thresholds, but not for precision metrology. The 24-pin PDIP format is particularly convenient for through-hole prototypes, test fixtures, and legacy panel boards. Layout must account for analog input routing and bypass capacitors, while firmware must coordinate conversion start, channel selection, bus read timing, and power-down control.
推薦
Battery-Powered Monitoring
The MAX113CNG+ is appropriate for low-duty-cycle monitoring equipment because its 1 uA power-down current helps reduce consumption between measurement bursts. The converter can sample four channels at 400 ksps when active and then place the device into its low-power shutdown state under software control. Its 8-bit resolution is useful for battery state indication, position sensing, and coarse environmental measurements where higher accuracy is not required. The single +3 V rail fits systems whose battery-derived supply operates at 3.3 V. Firmware should minimize active conversion time, and the PCB should keep sensitive analog traces away from digital bus lines. For new battery products, a modern low-power SAR ADC may provide greater resolution and a smaller footprint.
推薦
Threshold and Limit Control
The MAX113CNG+ can be used in threshold and limit-control systems where an 8-bit value is sufficient to identify operating regions rather than produce a high-precision measurement. Four analog inputs can be sampled sequentially at up to 400 ksps, allowing the controller to monitor setpoint-like signals rapidly. For example, a legacy controller can convert each channel, compare the digital value against programmed limits, and activate an alarm or control output when a threshold is crossed. The parallel interface supports direct connection to microprocessor-compatible buses. Calibration requirements should remain modest, but offset, gain error, reference stability, and input settling still need to be characterized for each board. Software must avoid treating the 8-bit output as having more accuracy than its stated resolution and reference performance.
推薦
Educational and Legacy Test Equipment
The MAX113CNG+ is practical for educational benches and legacy test equipment because it combines four analog inputs, an 8-bit parallel result, and a 400 ksps conversion rate in an inspectable 24-pin PDIP package. Students can connect the microprocessor-compatible bus to a controller, visualize sampling and channel selection, and experiment with calibration, thresholds, and power-down behavior without adopting a complex serial ADC interface. Through-hole construction also simplifies breadboard and prototype assembly. The 1 uA shutdown specification makes power-state experiments possible, although normal operating current and settling requirements must be obtained from the full datasheet. Since availability is limited by the obsolete lifecycle status, builders should retain the original device for repair and training rather than treat it as a default new-design choice.
推薦
Data Acquisition Backplane
The MAX113CNG+ can serve as a four-channel front end on a legacy parallel data-acquisition backplane. The microprocessor-compatible output reduces the need for a serial protocol converter, and 400 ksps throughput allows the controller to refresh several channels rapidly. Such a system can collect process trends, digital potentiometer positions, or simple transducer outputs into an external memory and then transmit the results through a communications controller. The 24-pin PDIP footprint supports repairable through-hole boards, although it occupies substantially more board area than a surface-mount ADC. Engineering validation should include input multiplexing timing, bus contention, ground partitioning, reference decoupling, and processor reset behavior. For new backplanes, compare the obsolete MAX113 family against current parallel-interface converters before committing the mechanical design.

主要差異化特點
- Four-channel acquisition in one converter (對比MAX163CCNG)
- Direct legacy-processor connectivity (對比MAX1271AENG+)
- Higher conversion throughput than the verified single-channel SAR comparator (對比MAX163CCNG)
設計說明
Route the four analog inputs away from the parallel data bus, enable pins, and switching supply nodes. Although the verified excerpts do not provide the complete input-range and settling-time tables, those details must be checked in the manufacturer datasheet before layout release. Keep the converter and any reference components near the controller, provide short ground returns, and place input bypass components at the corresponding pins where the datasheet recommends them.
Design the 3 V supply and decoupling around the manufacturer's pinout and recommended operating circuit. The verified data confirms a single +3 V supply and a 1 uA power-down current, but it does not establish the active supply-current limit or permitted supply range. Verify both before enabling the ADC, and ensure the host controller cannot drive data or control pins while the converter is powered down.
Do not substitute a 12-bit single-channel ADC merely because it uses a 24-pin PDIP; the verified MAX163CCNG comparison changes resolution, input count, architecture, and sampling rate. For a physical replacement, use the manufacturer ordering table to distinguish MAX113CNG+, MAX113ENG, and MAX113MRG by package, temperature grade, and accuracy suffix. A footprint match alone does not establish complete timing, input-range, or logic compatibility.
The parallel interface can create simultaneous output switching on the controller side, so keep digital traces short and provide a clear return path between the ADC and host. Where multiplexing is used, allow the acquisition interval required by the datasheet before interpreting the output. At 400 ksps, acquisition, conversion, and bus-access timing must be evaluated together; the headline throughput rate should not be treated as guaranteed end-to-end sampling latency.
合規資訊
The verified Avaq comparison identifies the MAX113CNG+ as RoHS compliant. No verified evidence was supplied for REACH, halogen-free status, conflict-mineral compliance, or lead-free classification, so those fields remain unknown. The commercial temperature grade is taken from the Partstack result.
