MAX153EPP+ - 1Msps 8-Bit ADC with 1uA Power-Down | Analog Devices
MPN： MAX153EPP+ ✓ 啟用中MAX153EPP+ 概覽
An ADC is a data-acquisition interface that converts an analog voltage into a digital value for processing by a microprocessor, microcontroller, or other digital controller. The MAX153 belongs to the parallel-output ADC family within the broader data-converter and interface IC hierarchy. It combines a 1Msps sampling capability with an 8-bit resolution and a power-down state, which can help control system power consumption when continuous conversion is not required.
The MAX153EPP+ provides a 1Msps conversion rate, 660ns conversion time, 8-bit resolution, one analog input, and 1uA power-down current. These specifications make it suitable for industrial control, instrumentation, sensor acquisition, and embedded systems requiring a direct parallel ADC interface. The manufacturer product page identifies the MAX153 as a production device and lists a starting list price of $14.17 as of 2026-10-30.
The half-flash conversion architecture is intended to support microprocessor-compatible interfacing while maintaining a 1Msps sampling rate. The device accepts either unipolar or bipolar input arrangements, giving designers flexibility when conditioning signals from sensors, transducers, dividers, and other analog sources. Its 20-pin PDIP package provides a through-hole mounting option for conventional industrial and laboratory boards.
Typical applications include process-control monitoring, laboratory measurement equipment, digital panel meters, sensor interfaces, industrial automation, and embedded data-acquisition systems. In each case, the parallel ADC outputs can be read by a suitable processor bus, while the power-down pin can reduce consumption during inactive periods. Designers should verify signal ranges, timing margins, and processor logic levels against the complete manufacturer datasheet.
For a new design, confirm the MAX153EPP+ supply configuration, input range, conversion timing, output coding, and processor interface before layout. The provided data does not include a verified complete pinout, thermal ratings, absolute maximum ratings, or detailed timing tables, so those values should be taken directly from the official MAX153 datasheet rather than inferred.

典型應用
MAX153EPP+ 適用於 6 應用s: Industrial Process Monitoring, Digital Panel Meters, Laboratory Measurement Equipment, Embedded Sensor Acquisition, Power Supply and System Monitoring, Legacy Data-Acquisition Systems.
Industrial Process Monitoring
The MAX153EPP+ fits legacy industrial process-monitoring systems that require rapid conversion of a single analog control or sensor signal. Its 1Msps sampling rate and 660ns conversion time provide a responsive parallel ADC front end for panel meters, controller inputs, and automation equipment. The 8-bit resolution is appropriate when the final control or display resolution does not require more than 256 codes. Install it in a through-hole 20-pin PDIP design, connect its microprocessor-compatible outputs to the controller, and use the 1uA power-down state during idle periods. Exact input scaling, acquisition timing, and grounding must follow the official datasheet.
推薦
Digital Panel Meters
The MAX153EPP+ is suitable for digital panel-meter designs that acquire a unipolar or bipolar sensor signal and present the result through a parallel microprocessor interface. A 1Msps conversion rate is more than adequate for many slowly changing process measurements, while the 8-bit output provides a simple digital value without a serial protocol converter. Place the device in a conventional through-hole PCB and connect its parallel outputs to the meter controller. The 660ns conversion time and 1uA power-down current help balance responsiveness with idle power consumption. Verify the exact input range, output coding, and bus timing in the manufacturer documentation.
推薦
Laboratory Measurement Equipment
The MAX153EPP+ can serve as the acquisition converter in laboratory instruments that sample one analog measurement and transfer it to a digital processing section. Its 1Msps rate, 8-bit resolution, and half-flash conversion method provide a straightforward parallel-interface solution for educational instruments, waveform monitors, and bench prototypes. The converter accepts unipolar or bipolar inputs, allowing designers to select the signal arrangement that best fits the front end. Use the single +5V or dual ±5V configuration supported by the design, and observe the complete acquisition and settling requirements. The 1uA power-down state is useful when the instrument enters a low-power standby mode.
推薦
Embedded Sensor Acquisition
The MAX153EPP+ is appropriate for embedded sensor interfaces requiring a single-channel, parallel ADC rather than a serial SPI or I2C converter. The 1Msps rate supports responsive acquisition from suitable sensors, and the 8-bit resolution can satisfy basic temperature, level, position, or contact-sensing tasks where higher fidelity is unnecessary. Connect conditioned sensor voltages to the converter, read the parallel outputs through the embedded controller, and assert POWERDN when sampling is not required to reduce current to 1uA. Sensor settling time, source impedance, reference accuracy, and input range must be evaluated because those details are not present in the supplied verified data.
推薦
Power Supply and System Monitoring
The MAX153EPP+ can monitor a representative analog system voltage in a power-control or fault-detection subsystem. A 1Msps conversion rate allows repetitive measurements, while the 8-bit result provides enough resolution for supervisory threshold decisions in many designs. The unipolar input capability is useful for rails scaled into the converter input range, and the 1uA power-down state helps minimize consumption when continuous monitoring is unnecessary. Place the converter in the 20-pin PDIP footprint and interface its parallel outputs with the supervising controller. The official datasheet should define the permitted input range, output coding, and timing before this function is committed to production.
推薦
Legacy Data-Acquisition Systems
The MAX153EPP+ is a practical choice when maintaining or recreating a legacy parallel data-acquisition architecture. The through-hole 20-pin PDIP package, 1Msps rate, 8-bit resolution, and microprocessor-compatible outputs align with established 8-bit control systems. Its single +5V or dual ±5V supply options can simplify adaptation of older instrumentation, and the POWERDN input can reduce standby consumption. Because the provided material does not establish a complete verified pinout, engineers must compare every connection against the official MAX153 datasheet and verify timing margins with the processor bus. It is best suited where modern serial converters would require substantial board redesign.

設計說明
Do not treat the matching headline specifications of MAX153EPP+ and MAX153CPP+ as proof of unconditional interchangeability. Confirm every pin name, supply arrangement, input range, output coding, conversion timing, and absolute maximum rating against the official datasheets. The supplied comparison data establishes the same 20-pin DIP format, 1Msps rate, 8-bit resolution, 660ns conversion time, and 1uA power-down current, but it does not provide a complete pin-by-pin validation.
Route the analog input directly to the converter and keep it away from digital output and clock lines. Use a compact, low-impedance connection from the source, place any input filtering or conditioning network close to the relevant pins, and provide normal supply bypassing near the device. Grounding and return-current paths should be arranged so converter currents do not share noisy paths with analog signal returns. Exact capacitor values and layout should be based on the complete manufacturer application guidance.
Use the single +5V or dual ±5V configuration that matches the selected input mode and the rest of the circuit. Assert POWERDN only with logic levels compatible with the device, and do not assume that the 1uA shutdown specification represents total board consumption. Processor I/O, pull resistors, references, analog front-end stages, and support circuitry may continue to draw power while the ADC is disabled, so calculate the complete standby budget before selecting it for battery-operated equipment.
