MAX160CPN+ - 8-Bit 250 ksps SAR ADC | Maxim Integrated
MPN： MAX160CPN+ ✓ 啟用中MAX160CPN+ 概覽
An ADC converts a continuous analog voltage into a numeric value for processing, storage, or control. The MAX160CPN+ belongs to the SAR ADC hierarchy, where a successive-approximation register compares the input against a generated reference voltage during each conversion. Compared with flash and pipeline ADC architectures, this SAR approach combines a relatively simple conversion process with useful resolution and sampling speed for instrumentation, industrial measurement, and embedded data-acquisition systems.
The principal specifications include 8-bit resolution, one analog input, a 250 ksps sampling rate, a parallel output interface, 5 V operation, and an 18-pin PDIP package. The + suffix identifies the lead-free ordering option within the MAX160 product family. Its 18-pin through-hole format also facilitates prototyping and replacement in legacy parallel-interface designs that do not use a compact surface-mount footprint.
The single-input architecture concentrates performance on one conversion channel at a time. If the source changes rapidly between samples, the system must either use an external sample-and-hold circuit or synchronize acquisition timing so that the SAR process captures a stable input. The 250 ksps rating means the converter can complete approximately 250,000 conversions per second under its specified operating conditions.
Typical uses include industrial process monitoring, legacy control-system data acquisition, laboratory measurement interfaces, and embedded equipment that reads a conditioned analog sensor signal. The parallel output allows the converted code to be read by compatible microprocessor or programmable-logic circuitry, while the 5 V supply simplifies integration with conventional digital systems.
A critical design consideration is the analog front end. Input range, reference accuracy, conversion timing, acquisition time, and logic-level compatibility should be checked against the manufacturer datasheet before signal-chain design begins. Decoupling and grounding must follow the recommended application circuit to reduce switching transients and digital coupling into the conversion result.
This product summary combines the MAX160CPN+ electrical identity, package details, sourcing context, pin-compatible family options, and application guidance into an engineering-focused reference for evaluating an 8-bit 250 ksps SAR ADC in a parallel-interface acquisition design.

典型應用
MAX160CPN+ 適用於 6 應用s: Industrial Process Measurement, Embedded Data Acquisition, Laboratory Measurement Interface, Legacy Control-System Upgrade, Precision Voltage Acquisition, Educational Electronics Prototyping.
Industrial Process Measurement
The MAX160CPN+ is suitable for acquiring conditioned process signals in industrial instrumentation because its 8-bit resolution and 250 ksps conversion rate provide 250,000 samples per second for measurement or monitoring. Place the ADC behind a sensor-conditioning amplifier, protection network, and antialiasing filter so that the analog node remains within the MAX160 input range. Its single 5 V supply simplifies interface design, while the parallel output can connect directly to compatible legacy microprocessor or programmable-logic circuitry. The primary qualification is environmental: the listed 0 C to +70 C operating range requires enclosure temperature control or selection of a wider-temperature family member.
推薦
Embedded Data Acquisition
The MAX160CPN+ supports embedded data-acquisition designs that read one analog channel and transfer the 8-bit result through a parallel bus. At 250 ksps, it is useful for fast feedback loops, sampled condition monitoring, and digital control blocks requiring more frequent updates than a low-rate general-purpose ADC would provide. The microprocessor-compatible parallel interface can shorten the path between conversion results and system logic. Use a stable reference, local supply bypassing, and a return path for digital signals so converter activity does not distort the analog measurement.
推薦
Laboratory Measurement Interface
The MAX160CPN+ can form the conversion stage of a laboratory measurement interface for slow or medium-speed analog inputs. Its 8-bit resolution suits coarse digital meter and instrumentation designs, while the 250 ksps rate allows the interface to sample faster than many panel-meter update rates. The 18-pin PDIP package is particularly convenient for breadboard, through-hole, and legacy instrument prototypes because it is easy to inspect and replace. For accuracy, connect the input through a high-impedance buffer and low-pass filter, isolate analog and digital return currents, and reference the converter from a low-noise source.
推薦
Legacy Control-System Upgrade
The MAX160CPN+ fits legacy control systems that retain an 18-pin parallel ADC interface but require a clearly defined 8-bit conversion stage rated to 250 ksps. Its microprocessor-compatible data output can support direct acquisition by older controller hardware, avoiding an unnecessary redesign of the bus architecture. The single analog input keeps the interface compact, although multiplexed or simultaneous measurement needs require additional front-end switching or another converter. Before insertion, verify signal polarity, chip-select and conversion-control timing, logic thresholds, and reference voltage against the original circuit.
推薦
Precision Voltage Acquisition
The MAX160CPN+ can digitize a precision conditioned voltage when the desired result fits an 8-bit code and the acquisition system benefits from a 250 ksps SAR conversion process. Position it after an instrumentation amplifier or precision buffer to maintain source impedance and preserve analog signal quality. A dedicated reference and careful grounding are essential because reference variation and comparator error affect code stability. The converter's -15 V precision ADC classification describes the device family positioning, but the actual allowable input span must be confirmed in the datasheet before scaling the analog signal.
推薦
Educational Electronics Prototyping
The MAX160CPN+ is practical for educational prototypes that demonstrate analog-to-digital conversion, parallel digital buses, sampling concepts, and embedded signal acquisition. Its 250 ksps maximum rate makes timing experiments possible, while the 18-pin PDIP format is easy to mount on perforated boards and prototype platforms. Students can compare output codes as the input changes, observe chip-select and conversion timing, and study the effect of filtering on sample accuracy. The through-hole package also makes the device straightforward to replace if a prototype is damaged.

設計說明
Route the eight parallel output lines away from the analog input and reference nets, especially the least-significant output bit and the conversion-control signal. Keep the analog trace short, use a continuous ground reference beneath it, and place the input bypass network close to the corresponding pins. This reduces capacitive coupling from the 250 ksps conversion process and helps preserve stable code readings.
Use the manufacturer's recommended application circuit as the basis for the PCB rather than substituting generic decoupling values. Place supply and reference capacitors at the associated device pins, provide a low-impedance return for digital output currents, and maintain separation between analog and digital paths. The 18-pin PDIP format simplifies routing, but correct pin-1 orientation and lead spacing are still essential.
Do not treat the 250 ksps sampling rate as the usable bandwidth of an arbitrary source. A changing input may require a sample-and-hold circuit, while a high source impedance can disturb the SAR acquisition network. Also verify chip-select polarity, conversion timing, and logic thresholds before connecting the parallel outputs to a host processor.
Apply a stable 5 V supply and decouple it close to the device according to the manufacturer application diagram. Reference noise and supply variation can affect code accuracy even when the ADC resolution is nominally 8 bits. Keep the analog reference source quiet and avoid routing digital return currents through the analog ground reference path.
