MAX117EAI+T

Analog To Digital Converters (ADC) Overview

The MAX117EAI+T is an 8-bit, 8-channel analog-to-digital converter (ADC) from the MAX113/MAX117 family. It operates on a single +3.0V to +3.6V supply and achieves a conversion time of 1.8µs per channel, supporting up to 400ksps sampling rates. The device utilizes a half-flash architecture with an internal track/hold circuit and requires no external clock. Power consumption is typically 1.5mA in operating mode and reduces to 1µA in power-down mode. It features latched three-state outputs for direct microprocessor bus interfacing and supports ratiometric reference inputs.

Analog To Digital Converters (ADC) Feature Summary

• Microprocessor-compatible parallel interface with latched three-state data outputs
• Integrated internal track/hold circuitry for fast signal acquisition
• Configurable power-down mode reducing current consumption to microamp levels
• Ratiometric reference input capability for flexible voltage scaling

Analog To Digital Converters (ADC) Applications

• Battery-powered portable equipment
• Remote data acquisition systems
• System-health monitoring applications
• Communications systems

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'EAI' corresponds to the SSOP-28 package and -40°C to +85°C temperature range as listed in official documentation. Confirm RoHS compliance status through the manufacturer's current product release notes. Ensure the ordering code matches the exact pin configuration required for the target PCB layout.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an 8-bit resolution with multiple analog channels is required within a low-voltage system. The integrated track/hold simplifies analog front-end design by eliminating external hold capacitors. Consider the 1.8µs conversion speed and 1µA standby current for burst-mode battery applications where power efficiency is critical.

Analog To Digital Converters (ADC) Part Context

This part belongs to the MAX113/MAX117 series of 8-bit ADCs manufactured by Analog Devices/Maxim Integrated. The MAX117 variant specifically provides eight analog input channels, whereas the MAX113 offers four. Both share identical electrical characteristics and interface protocols, differing primarily in channel count and package pinout.

Analog To Digital Converters (ADC) Replacement Considerations

The MAX113 serves as a functional substitute if only four analog input channels are required. For applications requiring five or more channels, the MAX117 variants remain the primary option. Verify that any replacement maintains the same SSOP-28 package dimensions and electrical specifications.
