MAX1241AEPA

Analog To Digital Converters (ADC) Overview

The MAX1241AEPA is a low-power, 12-bit successive-approximation analog-to-digital converter (ADC) in an 8-pin PDIP package. It operates on a single supply voltage ranging from +2.7V to +5.25V and achieves a maximum throughput rate of 73ksps with a conversion time of 7.5µs. The device requires an external reference voltage applied to the REF pin, accepting input signals from 0V to VREF. It features a fast track/hold circuit with an acquisition time of 1.5µs and includes a three-wire serial interface compatible with SPI, QSPI, and MICROWIRE standards. Power consumption is 3mW at full speed, reducing to 5µW in shutdown mode.

Analog To Digital Converters (ADC) Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels. Confirm that the part matches the specified 8-pin PDIP package and electrical characteristics. Check for lead-free compliance markings if required by assembly specifications. Ensure proper handling procedures are followed during storage and installation.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an external precision voltage reference is available and integrated into the system design. It is suitable for applications requiring low power consumption and small footprint within an 8-pin package. Consider the need for an external clock source and verify compatibility with the host microcontroller's serial interface timing requirements.

Analog To Digital Converters (ADC) Part Context

This device belongs to the MAX1240/MAX1241 family of low-power, 12-bit serial ADCs. While the MAX1240 variant integrates an internal 2.5V reference, the MAX1241 specifically requires an external reference source. Both share identical architecture, performance metrics, and packaging options, differing primarily in reference configuration.

Analog To Digital Converters (ADC) Replacement Considerations

MAX1240AEPA+ serves as a functional substitute if an internal 2.5V reference is acceptable and no external reference is utilized.
