MAX152CAP+ - 8-Bit 400ksps ADC | Maxim Integrated
MPN: MAX152CAP+ ✓ فعالMAX152CAP+ جائزہ
An ADC is a data-conversion IC that converts an analog voltage into a digital code for processing, storage, or control. The MAX152 belongs to the ADC > data converter > signal-processing IC hierarchy and combines parallel digital output with low-power operation. Its half-flash architecture provides 400 ksps throughput while keeping the converter suitable for compact control and measurement systems.
Key features include an 8-bit resolution, 400 ksps sampling rate, 1.8 µs conversion time, and 1 µA power-down current. Operating current is 1.5 mA, and the converter has a 300 kHz full-power input bandwidth. The internal track-and-hold circuit simplifies acquisition of rapidly changing analog signals, while the parallel interface supports direct connection to suitable microprocessor or logic devices.
Technically, the converter provides a practical balance between sampling speed, resolution, supply options, and power consumption. Its input system supports unipolar and bipolar operation, making it adaptable to sensor signals, process-control inputs, and digital measurement equipment. The 20-pin SSOP outline also permits reuse of a compact PCB footprint while keeping the converter separate from the wider SOIC package family.
Typical applications include industrial process measurement, digital panel instruments, battery-operated data-acquisition equipment, feedback control, and embedded acquisition systems. A 400 ksps conversion rate is useful where analog input changes faster than a slow display or control loop, while the 1 µA shutdown current helps preserve battery life during inactive periods.
Designers should verify the analog input range, supply configuration, digital output timing, and acquisition timing before fixing the clocking scheme. Short, controlled traces and a stable reference arrangement are important because converter accuracy is affected by source impedance, signal noise, and input settling behavior.
This page consolidates the verified MAX152CAP+ specifications, sourcing information, replacement constraints, and practical selection guidance. It also distinguishes true package-compatible alternatives from reel-code or temperature-grade variants so engineers can make an evidence-based drop-in decision rather than relying on a broad similarity search.

عام استعمالات

Industrial Process Measurement
The MAX152CAP+ fits industrial process-measurement channels that require up to 400 ksps sampling, an 8-bit parallel result, and operation from a +3 V to +3.6 V supply. Its 1.8 µs conversion time permits rapid acquisition of sensor signals, while the internal track-and-hold simplifies the front end. The 300 kHz full-power bandwidth is useful for faster-varying process signals, but engineers must confirm that the sensor, amplifier, and analog filter settle sufficiently within the acquisition interval. The 1.5 mA operating current also suits distributed low-power measurement nodes better than a continuously enabled high-power data-acquisition system.

Digital Panel Instrumentation
The MAX152CAP+ is appropriate for digital panel instruments that convert a sensor or control signal into an 8-bit code for display and adjustment. Its 400 ksps throughput is more than adequate for many panel update rates, while the parallel interface can feed a controller without requiring a serial protocol converter. The device accepts unipolar or bipolar inputs, permitting selection according to the instrument’s signal range, and its 1 µA shutdown current helps control standby consumption. Accurate results still depend on stable excitation, suitable source impedance, input filtering, and calibration of the displayed engineering unit.

Battery-Powered Data Acquisition
The MAX152CAP+ supports battery-powered data acquisition because it consumes 1.5 mA while operating and only 1 µA in power-down mode. Designers can enable the converter during a measurement window and place it into shutdown between samples, helping preserve energy in portable instruments. Its 900 ns power-up time allows the system to react quickly after enable, while the 400 ksps conversion rate supports burst acquisition when many samples must be captured. The overall battery budget must also include the sensor, analog conditioning, digital control, and communications circuitry.

Feedback Control Systems
The MAX152CAP+ can be used as the sensing element in a feedback-control loop when 8-bit resolution is adequate and inputs change at a rate compatible with its 400 ksps conversion capability. The 1.8 µs conversion time provides a short acquisition interval, and the internal track-and-hold reduces the number of external timing functions required. For motor, actuator, or temperature-control systems, the engineer should compare the loop update time with conversion and settling time and should include suitable filtering to prevent noise from destabilizing the control loop.

Embedded Acquisition System
The MAX152CAP+ is useful in embedded acquisition systems where an 8-bit parallel ADC can connect directly to compatible digital logic. Its single +3 V supply operation, 20-pin SSOP outline, and 400 ksps rate support compact mixed-signal boards. The internal track-and-hold accepts the sampled input, while the half-flash architecture produces a digital result in 1.8 µs. The design must observe acquisition, conversion, and data-read timing, and it should use controlled input routing and bypassing to keep switching and digital coupling from affecting the sampled code.
تجویز کردہ
Event and Waveform Monitoring
The MAX152CAP+ can capture moderate-resolution event waveforms at up to 400 ksps when the phenomenon of interest falls within its 300 kHz full-power bandwidth. The 8-bit resolution is useful for threshold, timing, and trend observations rather than high-fidelity waveform reconstruction. Its 1.8 µs conversion time and internal track-and-hold support closely spaced samples, but the designer must provide enough analog gain, anti-alias filtering, memory, and trigger logic to retain the relevant portion of the event. Power-down operation can also reduce consumption between acquisition bursts.

ڈیزائن نوٹس
Choose the analog input source impedance and acquisition time together. The MAX152CAP+ includes an internal track-and-hold and converts in 1.8 µs, but the external source must still charge the sampling network within the allowed settling interval. Keep the input trace short, place any input capacitance specified by the manufacturer close to the ADC pin, and place normal-anti-alias filtering ahead of the converter rather than after the digital output.
Route the eight parallel output lines away from the analog input and supply nodes, especially where acquisition and digital-output edges occur simultaneously. Keep the bypass capacitor network close to the supply pins and provide a low-impedance ground reference for both the analog and digital return currents. Because the verified sources do not provide the full pin table, engineers must follow the manufacturer layout and pin-description drawings before defining the SSOP-20 land pattern.
Budget for the 1.5 mA operating current, the converter’s dynamic demand, and the current required by external logic rather than relying only on the 1 µA shutdown figure. The 1 µA power-down mode is valuable for duty-cycled acquisition, but supply settling must satisfy the device’s operating requirements before conversion begins. The verified 900 ns power-up value should therefore be checked against the system’s enable-to-sample timing instead of being treated as complete system readiness.
تعمیل کی معلومات
The supplied verified excerpts do not state RoHS, REACH, lead-free, halogen-free, or conflict-minerals status. The MAX152CAP+ is an 8-bit data-converter IC, so AEC-Q100 qualification is not applicable unless an automotive-qualified ordering option is specifically identified.
