MAX11604EEE+

Analog To Digital Converters (ADC) Overview

The MAX11604EEE+ is an 8-bit, 12-channel analog-to-digital converter (ADC) from the MAX11600–MAX11605 family. It features a successive-approximation register (SAR) architecture with an internal track/hold circuit and a 4.096V internal voltage reference. The device operates on a single supply of 4.5V to 5.5V and supports a maximum sampling rate of 188ksps via a high-speed I²C-compatible 2-wire serial interface. It provides software-configurable unipolar or bipolar input modes and includes an internal FIFO for channel-scan operations.

Analog To Digital Converters (ADC) Feature Summary

• Internal track/hold circuitry and 4.096V voltage reference
• Software-selectable unipolar/bipolar operation and single-ended/pseudo-differential inputs
• AutoShutdown™ power-down mode reducing current consumption below 1µA

Analog To Digital Converters (ADC) Applications

• Handheld portable applications
• Medical instruments
• Battery-powered test equipment
• Solar-powered remote systems
• Received-signal-strength indicators

Analog To Digital Converters (ADC) Procurement Notes

Verify the component against official Analog Devices documentation to confirm pinout compatibility and electrical specifications. Ensure the operating voltage range matches the system requirements, as this specific variant requires a 4.5V to 5.5V supply. Check for lead-free/RoHS compliance markings on the package top marking to ensure authenticity.

Analog To Digital Converters (ADC) Selection Notes

Select the MAX11604EEE+ when a high channel count is required within a limited pin footprint. This model is appropriate for designs needing 12 analog inputs with an integrated reference, eliminating external components. Consider the 16-pin QSOP package constraints and verify that the host microcontroller supports the necessary I²C timing modes for data acquisition.

Analog To Digital Converters (ADC) Part Context

This component belongs to the MAX11600 series, which offers varying channel counts and resolutions. While other models in the family provide 4 or 8 channels, the MAX11604 specifically addresses applications requiring 12 channels. It shares the same low-power SAR architecture and I²C interface found across the series but is distinguished by its higher channel density and specific 4.096V internal reference configuration.

Analog To Digital Converters (ADC) Replacement Considerations

The MAX11605EEE+ serves as a direct functional substitute within the same package, differing only in its 2.048V internal reference voltage. For lower channel requirements, the MAX11602EEE+ (8 channels) may be considered if pin compatibility allows.
