MAX11627EEE/V+TCLS - 12-Bit 300ksps ADC w/ FIFO, QSOP-16 | Maxim
MPN: MAX11627EEE/V+TCLS ✓ نشطMAX11627EEE/V+TCLS نظرة عامة
An ADC (Analog-to-Digital Converter) is a semiconductor device that converts a continuous-time analog voltage into a discrete digital code. Successive-approximation (SAR) ADCs use an internal DAC and comparator to binary-search the input, achieving 12-bit resolution at up to 300 ksps while consuming only a few milliwatts. SAR ADCs sit within the broader hierarchy of mixed-signal ICs and are widely used in industrial control, instrumentation, and sensor-interface signal chains where moderate speed and precision are required.
Key specifications include 12-bit resolution, 300 ksps maximum sampling rate, single-ended analog inputs across 4, 8, 12, or 16 channels (family-wide), an internal 4.096 V reference, an internal FIFO for autonomous burst capture, and a low-power shutdown mode. The QSOP-16 (5.0 mm × 3.0 mm body) package exposes all analog, digital, and power pins, while the SPI serial interface supports daisy-chaining of multiple MAX1162x devices on a single bus.
Internally, the device uses a capacitive charge-distribution SAR architecture, an on-chip bandgap-derived reference with factory-trimmed accuracy, and dedicated input track-and-hold circuitry. The result is excellent AC performance at low conversion rates without requiring external precision components or calibration.
Typical applications include multichannel data-acquisition front ends, patient monitoring, sensor-array sampling, HVAC controllers, and portable instrumentation. The wide channel count and FIFO make the device well suited to scanning multiple analog signals before waking a microcontroller to read the conversion queue.
Design with this part using the recommended 0.1 uF decoupling capacitor close to VDD, and place the analog inputs on quiet ground-referenced traces routed away from switching lines. Confirm that host MCU SPI timing satisfies the 40 ns minimum SCLK period specified in the datasheet.

التطبيقات النموذجية
MAX11627EEE/V+TCLS مناسب لـ 6 التطبيقs: Multichannel Data Acquisition Front End, Portable Patient Monitoring, Sensor Array Sampling, HVAC Building Controllers, Portable Instrumentation, Industrial Control Signal Chains.
Multichannel Data Acquisition Front End
The MAX11627EEE/V+TCLS fits multichannel data acquisition front ends where 12-bit precision at 300 ksps is sufficient. Its 4 to 16 single-ended analog inputs (family-dependent) and internal FIFO allow scanning multiple analog sources before waking the host MCU. The on-chip 4.096 V reference eliminates external reference components, reducing BOM cost. With its QSOP-16 footprint and SPI interface, it integrates into compact DAQ modules used in industrial control and instrumentation.

Portable Patient Monitoring
The MAX11627EEE/V+TCLS suits portable patient monitoring where low power and small size are required. Its 300 ksps sampling and 12-bit resolution are sufficient for ECG, SpO2, and temperature sensor front ends. The internal FIFO and shutdown mode minimize host CPU activity and battery drain during continuous monitoring. The QSOP-16 small-form-factor package keeps the analog chain compact on portable medical PCBs.

Sensor Array Sampling
The MAX11627EEE/V+TCLS is well suited to scanning sensor arrays including temperature, pressure, and strain-gauge bridges. The internal FIFO buffers conversion results so the host processor can sleep between burst scans, reducing system power. Its 12-bit resolution over the 0 to VREF range yields 1 mV LSB precision when VREF=4.096 V - adequate for most sensor-element digitization. The SPI interface simplifies routing in dense sensor boards.

HVAC Building Controllers
The MAX11627EEE/V+TCLS supports HVAC building controller designs where multiple analog inputs (temperature, humidity, airflow, pressure) must be digitized with 12-bit precision. The internal reference eliminates trimming, easing factory calibration of HVAC wall modules. The QSOP-16 industrial -40C to +85C operating range is well-matched to outdoor and mechanical-room HVAC installations.

Portable Instrumentation
The MAX11627EEE/V+TCLS serves portable handheld instruments including digital multimeters, oscilloscope front ends, and field-testers. Its small QSOP-16 package, internal reference, and shutdown mode enable battery-powered designs where the host MCU can power-cycle the ADC between measurement sweeps. The 12-bit resolution is sufficient for consumer and prosumer instrument-grade measurements.

Industrial Control Signal Chains
The MAX11627EEE/V+TCLS supports industrial control PLC analog input modules. Its 12-bit resolution at 300 ksps suits 4-20 mA loop current and 0-10 V industrial transducer inputs. The daisy-chain SPI mode allows multiple MAX1162x devices to share a single host port, expanding channel count on PLC backplanes. Industrial -40C to +85C operation tolerates factory-floor thermal environments.

ملاحظات التصميم
Place a 0.1 uF ceramic decoupling capacitor as close as possible to the AVDD pin and a separate 0.1 uF cap at the DVDD pin. A 10 uF bulk capacitor on the supply rail is recommended to handle transient current demands during conversions. The internal reference benefits from an external bypass cap on the REF pin per the datasheet layout guideline.
Route analog input traces as short as possible, away from digital lines and switching converter nodes. Use a ground-referenced analog ground plane under the QSOP-16 device; place the REF pin bypass capacitor immediately adjacent to its pin. Avoid running digital return currents under the analog input traces.
Ensure the host MCU SPI SCLK frequency stays below the MAX11627's 25 MHz max (40 ns minimum period per the datasheet). Do not operate with VDD below the 2.7 V minimum. Use the daisy-chain mode only when connecting multiple MAX1162x devices on the same CS line; a misconfigured CHAIN pin will leave the FIFO in an undefined state.
