MAX117CAI+T

Analog To Digital Converters (ADC) Overview

The MAX117CAI+T is an 8-bit, 8-channel analog-to-digital converter (ADC) from the MAX113/MAX117 family. It operates on a single +3V 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. It features latched three-state outputs for direct microprocessor bus interfacing without external logic. Power consumption is typically 1.5mA in operating mode and reduces to 1µA in power-down mode. The component is housed in a 28-pin SSOP package.

Analog To Digital Converters (ADC) Feature Summary

• Microprocessor-compatible parallel interface with latched three-state data outputs
• Integrated multiplexer supporting eight selectable analog input channels
• Low-power operation with programmable power-down mode reducing current to 1µA
• Ratiometric reference inputs allowing flexible voltage range configuration

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 ordering suffix 'T' against official documentation to confirm tape-and-reel packaging requirements. Confirm that the 'C' grade designation aligns with the required commercial temperature range of 0°C to +70°C for the target application environment.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an 8-bit resolution and 400ksps throughput are sufficient for the signal bandwidth. Ensure the system requires a single +3V supply and benefits from low standby current. Verify that the 28-pin SSOP footprint fits the PCB layout constraints and that the parallel interface matches the host controller's capabilities.

Analog To Digital Converters (ADC) Part Context

This part belongs to the MAX113/MAX117 series of 8-bit ADCs. 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 pin configuration within the same package families.

Analog To Digital Converters (ADC) Replacement Considerations

The MAX117EAI serves as a parameter-equivalent alternative offering an extended industrial temperature range (-40°C to +85°C). Direct replacements must maintain the 8-bit resolution, 8-channel multiplexing capability, and 28-pin SSOP form factor.
