MAX11627EEE+T

Analog To Digital Converters (ADC) Overview

The MAX11627EEE+T is a serial 12-bit analog-to-digital converter (ADC) featuring an internal track-and-hold circuit and a 4-channel single-ended analog multiplexer. It operates from a single +2.7V to +3.6V supply with an integrated 2.5V reference. The device supports a maximum sampling rate of 300ksps using an external clock and includes a 16-entry FIFO buffer for data storage. It utilizes a 10MHz SPI-/QSPI-/MICROWIRE-compatible serial interface and is housed in a 16-pin QSOP package, specified over the -40°C to +85°C temperature range.

Analog To Digital Converters (ADC) Feature Summary

• Integrated 4-channel analog multiplexer with track-and-hold functionality
• Built-in 2.5V voltage reference supporting unipolar input ranges
• On-chip 16-entry first-in/first-out (FIFO) buffer for efficient data handling
• Supports scan mode, internal averaging, and multiple clocking options

Analog To Digital Converters (ADC) Applications

• System Supervision
• Data-Acquisition Systems
• Industrial Control Systems
• Patient Monitoring
• Instrumentation

Analog To Digital Converters (ADC) Procurement Notes

Verify that the ordering suffix matches the required package type and lead-free status. Confirm the specific supply voltage requirements align with the design constraints, as this variant operates on a single low-voltage supply. Ensure the pinout corresponds to the 16-pin QSOP configuration before integration into the PCB layout.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a low-voltage operation between 2.7V and 3.6V is required. It is suitable for applications needing four single-ended inputs with high accuracy. Consider the internal 2.5V reference or the capability to use an external reference ranging from 1V to VDD based on system signal levels.

Analog To Digital Converters (ADC) Part Context

This part belongs to the MAX11626–MAX11629/MAX11632/MAX11633 family of 12-bit ADCs. While sharing core architecture, it differs from other family members by its specific 4-channel input count and lower voltage operating range compared to the 5V variants.

Analog To Digital Converters (ADC) Replacement Considerations

The MAX11626EEE+ serves as a direct functional replacement but requires a +5V supply and provides a 4.096V internal reference instead of 2.5V. Verify power supply compatibility and reference voltage adjustments when substituting.
