MAX1026BCEE+

Analog To Digital Converters (ADC) Overview

The MAX1026BCEE+ is a serial 10-bit analog-to-digital converter (ADC) featuring an internal reference and temperature sensor. It operates from a single +5V supply with a maximum sampling rate of 300ksps using an external clock. The device includes an on-chip FIFO, scan mode, internal clock mode, internal averaging, and AutoShutdown™. It provides eight configurable input channels supporting single-ended or differential inputs in unipolar or bipolar modes. The component utilizes a 10MHz SPI/QSPI/MICROWIRE-compatible serial port and is housed in a 16-pin QSOP package.

Analog To Digital Converters (ADC) Feature Summary

• Integrated internal temperature sensor with specified accuracy for system monitoring
• On-chip 16-entry first-in/first-out buffer to manage data flow without bus contention
• Configurable analog multiplexer supporting true differential track-and-hold for multiple channel configurations
• Low-power operation optimized for single +5V supply applications

Analog To Digital Converters (ADC) Applications

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

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'CEE+' against the manufacturer's current ordering guide to confirm lead-free compliance and RoHS status. Confirm the operating temperature range matches the 'E' designation (-40°C to +85°C). Ensure the package type corresponds to the 16-pin QSOP format. Cross-reference the datasheet revision to validate pinout compatibility with existing designs.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 10-bit resolution and 300ksps throughput are required within a single-channel or multi-channel scanning architecture. Consider the integrated FIFO and internal reference if board space is limited. Evaluate the input configuration requirements, as the MAX1026 supports up to eight single-ended or four differential channels. Verify that the host microcontroller supports the required SPI/QSPI/MICROWIRE interface timing.

Analog To Digital Converters (ADC) Part Context

The MAX1026 belongs to the MAX1026/MAX1028/MAX1030 family of low-power serial ADCs. While the MAX1026 offers eight channels, the MAX1028 provides twelve channels and the MAX1030 provides sixteen channels. All devices share similar architectural features, including the SAR conversion technique, internal reference options, and temperature sensing capabilities, differing primarily in channel count and package availability.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements within the same family include the MAX1028BEEE+ and MAX1030BEEE+, which offer higher channel counts but maintain the same interface and electrical characteristics. Verify that the increased channel count does not impact power consumption or thermal requirements in the target application.
