MAX11602EEE+

Analog To Digital Converters (ADC) Overview

The MAX11602EEE+ is an 8-bit, 8-channel analog-to-digital converter (ADC) from the MAX11600–MAX11605 family. It operates on a single supply of 4.5V to 5.5V and features an internal 4.096V voltage reference. The device supports a maximum sampling rate of 188ksps with a typical supply current of 350µA. It utilizes an I²C-compatible 2-wire serial interface supporting up to 1.7MHz high-speed mode. The ADC provides software-configurable unipolar/bipolar and single-ended/pseudo-differential input modes. It is housed in a 16-pin QSOP package and is rated for operation over an extended industrial temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to ensure correct package type and lead-free compliance. Confirm that the required supply voltage aligns with the 4.5V to 5.5V specification for this variant. Check for any regional distribution restrictions or discontinuation notices prior to finalizing procurement plans.

Analog To Digital Converters (ADC) Selection Notes

Select the MAX11602EEE+ when eight analog input channels are required alongside an integrated 4.096V reference. Ensure the system operates within the specified 4.5V to 5.5V supply range. Consider the 16-pin QSOP package constraints for board layout. Verify that the I²C bus speed requirements match the supported 400kHz or 1.7MHz modes.

Analog To Digital Converters (ADC) Part Context

This component belongs to the MAX11600–MAX11605 series of low-power, multichannel ADCs. While other variants in the family offer different channel counts or reference voltages, the MAX11602EEE+ specifically combines eight channels with a 4.096V internal reference. It shares the same core SAR architecture and I²C interface as its siblings but is distinct in its pinout configuration and reference selection.

Analog To Digital Converters (ADC) Replacement Considerations

The MAX11603EEE+ serves as a direct functional substitute if a 2.048V internal reference is acceptable instead of 4.096V. Other members of the MAX1160x family may be considered if channel count or resolution requirements differ, though pin compatibility varies across the series.

Analog To Digital Converters (ADC) FAQ

What is the difference between single-ended and pseudo-differential input modes?

In single-ended mode, the conversion result is the difference between the selected analog input and ground. In pseudo-differential mode, the result is the difference between two selected analog inputs, where the negative input must remain stable relative to ground during conversion.

How does the AutoShutdown feature affect power consumption?

AutoShutdown powers down the device between conversions. This reduces the supply current to less than 1µA at low throughput rates, compared to 350µA at the maximum sampling rate of 188ksps.

Can the MAX11602EEE+ operate with an external reference voltage?

Yes, the full-scale analog input range can be determined by an externally applied reference voltage ranging from 1V to VDD, in addition to the internal 4.096V reference.
