MAX173CNG+ - 10-Bit 200ksps SAR ADC | Analog Devices
MPN: MAX173CNG+ ✓ সক্রিয়MAX173CNG+ সারাংশ
An ADC is an interface IC that converts an analog input voltage into a digital number for processing by a microcontroller, logic device, or other digital system. The MAX173CNG+ belongs to the ADC hierarchy as a single-channel SAR ADC. Successive-approximation operation internally compares the unknown input with a controlled reference and produces a digital result after a sequence of comparison steps.
The principal device characteristics visible in the verified distributor and manufacturer-related records are a 10-bit resolution, one analog input, SAR architecture, 200 ksps throughput, 5.25 V operating voltage, and a 24-pin through-hole PDIP package. These specifications make the converter appropriate for industrial instrumentation, sensor interfaces, process-control loops, and embedded measurement systems that do not require simultaneous sampling or resolution above 10 bits.
The MAX173CNG+ uses an internal reference, as shown in the available comparison data, and accepts a single-ended input. A single-ended architecture simplifies the signal path because the input is referenced to ground rather than requiring a differential pair. The 10-bit result provides 1,024 possible codes, while the 200 ksps rate supports sampling intervals of approximately 5 microseconds.
The 24-pin PDIP package is suitable for through-hole assembly and prototypes where component accessibility and straightforward socket or PCB insertion are useful. Its larger footprint differs from modern surface-mount ADC packages, so designers should confirm board area and insertion requirements before selecting it for new compact products.
The main design consideration is signal conditioning. The ADC can only reproduce an input that remains inside its valid input range and is presented with a source impedance compatible with the internal sampling network. External buffering, filtering, grounding, and reference-noise control can materially affect whether the converter achieves its intended measurement accuracy.
This page consolidates verified distributor specifications, lifecycle-oriented sourcing information, application guidance, and a conservative compatibility assessment. It does not infer missing electrical limits or claim substitute parts as drop-in replacements unless the available cross-reference evidence establishes the required package and pin compatibility.

সাধারণ ব্যবহার
MAX173CNG+ এর জন্য উপযুক্ত 6 অ্যাপ্লিকেশনs: Industrial Sensor Acquisition, Process Control Loops, Digital Thermometer and Metering, Laboratory Instrumentation, Embedded Control Interface, Power and Equipment Monitoring.
Industrial Sensor Acquisition
The MAX173CNG+ is appropriate for acquiring moderately slow analog sensor signals in industrial measurement equipment because it provides a 10-bit result, one single-ended input, and a 200 ksps conversion rate. The approximately 5 microsecond conversion time allows rapid periodic sampling, while the 24-pin PDIP package remains convenient for through-hole prototypes and maintenance-oriented industrial boards. The transducer should be conditioned so its output stays within the datasheet input range and presents a source impedance suitable for the internal sampling network. A sensor amplifier, anti-alias filter, and local reference bypass can improve repeatability. Because the converter has 1,024 possible output codes, system resolution is also limited by analog noise, reference stability, grounding, and signal-chain accuracy.

Process Control Loops
The MAX173CNG+ can support process-control feedback loops where the controller needs a fresh measurement every few microseconds but does not require more than 10 bits of resolution. Its 200 ksps conversion rate and single-ended SAR input simplify periodic sampling from pressure, temperature, or level transmitters. The 5.25 V supply matches integrated analog and digital systems designed around a conventional 5 V rail. Designers should provide a continuous-time antialias filter ahead of the input, maintain a low-impedance reference path, and connect the digital interface according to the exact manufacturer pinout. Through-hole packaging supports rugged laboratory and control prototypes, although the DIP footprint occupies more board area than a surface-mount ADC.

Digital Thermometer and Metering
A compact digital thermometer or general-purpose metering instrument can use the MAX173CNG+ to digitize a conditioned analog sensor signal at a practical rate of 200 ksps. The device offers 10-bit resolution, producing 1,024 codes, and its approximately 5 microsecond conversion time is more than adequate for many temperature, level, and pressure measurements. A low-noise reference and grounded input source are important because they establish the stability of the final numerical result. The 24-pin PDIP package is useful where sockets, through-hole repair, and straightforward inspection improve serviceability. Firmware should perform calibration or offset correction, and the signal path should be protected against ESD and electrostatic discharge.

Laboratory Instrumentation
MAX173CNG+ is a practical choice for educational, laboratory, and service equipment that measures one analog voltage at a time. The single-ended input reduces analog routing complexity, while the 200 ksps SAR conversion rate allows rapid calibration or repetitive measurements. The 24-pin PDIP package makes the converter straightforward to socket, probe, and replace in a through-hole instrument. Measurement quality depends on preserving the reference voltage, using a stable source impedance, and separating sensitive input traces from digital switching paths. The converter should be calibrated against a known source after installation. Compared with a 12-bit device, the MAX173CNG+ provides fewer numerical codes, so applications needing finer quantization should evaluate a 12-bit alternative even if its conversion rate is lower.

Embedded Control Interface
The MAX173CNG+ can serve as an analog measurement front end for an embedded controller requiring a moderate-rate, single-channel acquisition path. A 10-bit result is often sufficient for supervisory controls, setpoint monitoring, and coarse position feedback where the resulting 1,024-code span can be calibrated. The approximately 5 microsecond conversion time permits dense sampling, and the 24-pin PDIP package allows mixed assembly techniques on legacy or prototype boards. The interface must be checked carefully because the exact output coding and terminal functions are not reproduced in the supplied source excerpts. Firmware should convert unsigned or signed results according to the datasheet, and the PCB should place input and reference grounding paths carefully to reduce conversion-dependent error.

Power and Equipment Monitoring
The MAX173CNG+ can digitize a scaled voltage from power-supply or equipment-monitoring circuitry when 10-bit resolution and a 200 ksps sampling rate are adequate. Its single-ended SAR input permits periodic observation of one rail or sensor node at a time. The 5.25 V supply is convenient for conventional 5 V analog systems, and the through-hole PDIP package can simplify construction of a monitor board around an existing controller. Monitoring accuracy depends heavily on the divider ratios, input filtering, reference behavior, and grounding. Designers should check the input range and source-impedance requirements before scaling a power rail. A higher-resolution alternative may be preferable for very small calibration margins, while the MAX173CNG+ remains suitable where faster acquisition and simpler single-channel sampling are the priorities.

ডিজাইন নোট
Treat the analog input as a sampled rather than continuously observed node. Place an antialias filter close to the converter, keep the input trace short, and minimize parasitic capacitance around the input and reference terminals. Source impedance must remain compatible with the acquisition network specified in the manufacturer datasheet. If the sensor or divider has high output impedance, add a low-noise buffer rather than assuming that the 200 ksps conversion rate alone guarantees accurate results.
Use the exact terminal assignments from the Maxim Integrated datasheet before laying out the 24-pin PDIP footprint. The supplied records confirm the package and terminal count but do not expose the complete pinout, so assigning power, ground, reference, analog input, and digital outputs from general knowledge could create a hazardous board. Follow the datasheet pin drawing, preserve a common ground reference between analog and digital sections, and place required bypass capacitors directly beside their associated terminals.
Do not substitute a superficially similar DIP-24 ADC without checking resolution, output coding, clock requirements, acquisition timing, reference behavior, and logic levels. The supplied comparisons show MAX172AENG at 12 bits and 100 ksps and MAX163CCNG at 12 bits, demonstrating that another 24-pin SAR ADC can require substantial firmware and hardware changes. Also verify the commercial temperature limits, input range, output format, and absolute maximum ratings directly from the MAX173CNG+ datasheet before release to production.
