MAX153CPP+ - 8-Bit 1MSPS ADC with 1µA Power-Down | Analog Devices
料号： MAX153CPP+ ✓ 量产中MAX153CPP+ 概述
An ADC is a data-converter IC that translates an analog voltage into a digital code for processing by a microcontroller, microprocessor, comparator, or control system. The MAX153 belongs to the parallel-output ADC family, a functional subset of data converters and analog-to-digital converters. Its parallel interface transfers each 8-bit conversion result directly through dedicated digital output pins, making it suitable for designs that require deterministic sampling without a serial communication protocol.
Key features include 1 MSPS throughput, 8-bit resolution, a 660 ns half-flash conversion time, and a typical 1 µA power-down current. The converter accepts unipolar or bipolar analog inputs and supports both single +5 V and dual ±5 V operating arrangements. These characteristics are useful where compact, low-power, processor-compatible data acquisition is more important than high resolution.
The MAX153 uses a half-flash conversion architecture rather than a conventional successive-approximation or flash-only architecture. This approach supports the stated 660 ns conversion time and 1 MSPS sampling rate while presenting an 8-bit parallel result to the host processor. An active-low POWERDN input allows the converter to enter its low-power state when measurements are not required, reducing system power consumption during inactive intervals.
Typical uses include industrial process control, factory automation, test and measurement equipment, embedded instrumentation, and legacy data-acquisition systems. The 20-pin PDIP format also favors through-hole prototyping, repair, and legacy motherboard layouts where a modern fine-pitch package would require a different footprint and routing strategy.
The primary design consideration is interface timing: the host must read the 8-bit parallel output within the converter's permitted output timing window, while the analog input and supply references must satisfy the MAX153 operating requirements. Power-down should be used during idle periods, but power-state transitions must be coordinated with acquisition sequencing to avoid sampling an unsettled analog input.
This product page combines the verified Analog Devices MAX153 data, distributor pricing information, source links, and application-oriented guidance to provide engineering context beyond the basic distributor catalog description. It also distinguishes verified production information from package-level and cross-reference details that require further engineering confirmation.

典型应用
MAX153CPP+ 适用于 6 应用s: Industrial Process Control, Factory Automation and Counter Inputs, Legacy Data-Acquisition Systems, Test and Measurement Instrumentation, Embedded Control Signal Sampling, Low-Power Portable Data Logging.
Industrial Process Control
The MAX153CPP+ fits industrial process-control loops that need faster-than-control-loop sampling without the resolution of a modern high-speed converter. Its 1 MSPS conversion rate and 660 ns conversion time provide up to one million conversions per second, while the 8-bit parallel result can be read directly by a microprocessor. The device also accepts unipolar or bipolar inputs, giving designers flexibility when conditioning signals from sensors, transducers, and industrial I/O. The 20-pin PDIP package is especially useful for legacy controller boards that require through-hole assembly. For a new design, verify the commercial temperature grade and environmental requirements against the full Analog Devices datasheet before deployment.
推荐
Factory Automation and Counter Inputs
The MAX153CPP+ is suitable for acquiring rapidly changing counter, position, or event signals in factory automation equipment. Its 660 ns conversion time supports a 1 MSPS sampling rate, allowing the host processor to observe short timing intervals that a much slower successive-approximation converter could miss. The parallel 8-bit output avoids adding a serial clock and deserialization stage to older PLC or embedded controller architectures. Unipolar and bipolar input support broadens the range of conditioned signals that can be captured. Engineers should still verify input-bandwidth, settling-time, and acquisition-time requirements in the manufacturer datasheet before using the converter directly on fast edges.
推荐
Legacy Data-Acquisition Systems
The MAX153CPP+ is a practical choice for maintaining or expanding legacy parallel-bus data-acquisition systems because it combines an 8-bit microprocessor-compatible interface with a 20-pin PDIP package. The 1 MSPS rate provides more temporal resolution than typical slow ADC sections used in older control equipment, while single +5 V or dual ±5 V operation allows adaptation to different analog power architectures. Through-hole construction simplifies repair and avoids redesigning a mixed through-hole and surface-mount board. Because the verified information does not establish the complete pin table, replacement work should begin with a direct comparison against the original converter and the Analog Devices MAX153 datasheet, Revision 2.
推荐
Test and Measurement Instrumentation
The MAX153CPP+ can serve as the acquisition element in compact test and measurement instruments that need an 8-bit, 1 MSPS parallel ADC rather than a high-resolution serial converter. Its 660 ns conversion time permits rapid sampling of repetitive or transient waveforms, while the microprocessor-compatible output supports direct connection to digital acquisition logic. The converter accepts both unipolar and bipolar signals, simplifying front-end selection when the instrument must measure quantities around a bipolar reference. The 1 µA typical power-down current is also useful for portable equipment that spends substantial time between test sequences. Input bandwidth, sampling noise, linearity, and reference requirements must be checked in the full datasheet before setting measurement expectations.
推荐
Embedded Control Signal Sampling
The MAX153CPP+ is appropriate for embedded controllers that periodically sample analog control signals and benefit from a deterministic parallel interface. At 1 MSPS, the converter can acquire a substantially denser sequence of control values than a slow low-resolution converter, while the 660 ns conversion time helps constrain acquisition latency. The active-low POWERDN input can reduce current consumption to a typical 1 µA during idle periods, making the part useful in periodically operating equipment. Designers must coordinate power-down and wake timing with the host software, allow the analog source to settle, and verify that the digital output is captured within the timing limits shown in the manufacturer datasheet.
推荐
Low-Power Portable Data Logging
The MAX153CPP+ fits portable data-logging equipment where the host can power the converter down between acquisition bursts. Its typical 1 µA power-down current limits the converter's inactive contribution, while the 1 MSPS rate permits short, dense measurement bursts when data collection begins. The 8-bit parallel interface suits older portable processors and embedded controllers that lack a convenient serial ADC input, while the 20-pin PDIP package supports through-hole prototype and repair workflows. System-level power budgeting should include the active operating current, which is not provided in the verified excerpts, as well as sensor and processor standby consumption. Input conditioning must also preserve signal integrity during each wake and settling interval.

设计说明
Do not treat any 8-bit ADC as an automatic drop-in replacement. Before substituting MAX153CPP+CGP or another candidate, compare the ordering code, 20-pin PDIP footprint, every signal name, input range, reference arrangement, conversion timing, output access timing, and power-down polarity against the original schematic. The supplied cross-reference snippet identifies a related MAX153 listing but does not reproduce a complete pin table. The Analog Devices MAX153 datasheet, Revision 2, should be the controlling document, particularly for PCB rework on a live production board.
Use the POWERDN control only after confirming its active-low polarity in the manufacturer datasheet. Asserting power-down can terminate or invalidate a conversion, while releasing it may require a settling interval before the first valid code is captured. For a duty-cycled design, determine the complete energy budget from both the 1 µA typical power-down current and the active current, which was not included in the verified excerpts. Also ensure the host logic levels remain compatible when the ADC supply is disabled; a floating or partly powered input can create unpredictable current unless the original circuit includes suitable isolation or clamping.
Place the analog input and reference connections close to the appropriate MAX153 pins and keep digital output routing away from the sensitive input path. The 8-bit parallel bus creates multiple fast switching edges, so route the bus according to the host's acquisition timing and isolate it from high-impedance input nodes where practical. Through-hole DIP assembly does not remove the need for good grounding or short return paths. Compare the manufacturer's recommended application circuit and bypass-capacitor arrangement rather than substituting generic values without checking the complete operating conditions.
合规信息
The verified excerpts identify the MAX153 as a production commercial-grade product but do not provide explicit RoHS, REACH, lead-free, halogen-free, or conflict-minerals declarations. AEC-Q100 is not applicable because the product is identified as commercial grade rather than automotive grade.
