MAX1426EAI+

Analog To Digital Converters (ADC) Overview

The MAX1426EAI+ is a 10-bit, monolithic analog-to-digital converter (ADC) capable of a 10Msps sampling rate. It features a differential pipelined architecture with an internal track-and-hold amplifier and generates an internal +2.5V reference to provide a ±2V differential input range. The device operates on a single +5V analog supply and a separate +3V digital logic supply, consuming only 156mW. It is housed in a 28-pin SSOP package and supports an operating temperature range from -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix EAI against the datasheet ordering information to confirm the extended industrial temperature range (-40°C to +85°C). Confirm RoHS compliance status as indicated by the plus sign. Check current availability through authorized distributors, as lead times may vary based on manufacturing schedules.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 10-bit resolution at 10Msps is required with low power consumption. Ensure the application can accommodate the 28-pin SSOP footprint. Verify that the system clock jitter is minimized to maintain optimal SNR performance. Consider the need for external buffering if driving heavy capacitive loads on the digital outputs.

Analog To Digital Converters (ADC) Part Context

This part belongs to the MAX1426 family of high-speed ADCs. Pin-compatible alternatives include the MAX1424 and MAX1425, which offer higher data rates. The MAX1426 specifically targets applications requiring a balance between speed, resolution, and power efficiency in a compact surface-mount package.

Analog To Digital Converters (ADC) Replacement Considerations

For pin-compatible upgrades with higher throughput, consider the MAX1424 or MAX1425. Verify that the replacement part's voltage requirements and interface timing match the existing design constraints before substitution.
