MAX1241BCPA+

Analog To Digital Converters (ADC) Overview

The MAX1241BCPA+ is a low-power, 12-bit successive-approximation analog-to-digital converter (ADC) housed in an 8-pin PDIP package. It operates on a single supply voltage ranging from +2.7V to +5.25V and requires an external reference voltage at the REF pin. The device features a fast track/hold circuit with a 1.5µs acquisition time and supports throughput rates up to 73ksps. Power consumption is 3mW at maximum sampling speed and reduces to 5µW in shutdown mode. It utilizes a high-speed, 3-wire serial interface compatible with SPI, QSPI, and MICROWIRE protocols.

Analog To Digital Converters (ADC) Feature Summary

• Single-supply operation supporting voltages from +2.7V to +5.25V
• Integrated track/hold circuitry for signal acquisition
• Compatible with standard microcontroller serial interfaces
• Low power consumption with dedicated shutdown capability

Analog To Digital Converters (ADC) Applications

• Battery-powered systems
• Portable data logging
• Isolated data acquisition
• Process control instrumentation

Analog To Digital Converters (ADC) Procurement Notes

Verify that the component matches the specific ordering suffix 'CPA+' which indicates an 8-pin PDIP package and lead-free/RoHS compliance. Confirm the temperature range corresponds to the 'B' grade specification of 0°C to +70°C. Ensure the datasheet revision aligns with the required electrical characteristics for your design.

Analog To Digital Converters (ADC) Selection Notes

Select this model when an external reference voltage is preferred over an internal one. The MAX1241 differs from the MAX1240 by requiring an external reference input rather than providing an internal 2.5V source. Verify that the application can accommodate the 8-pin PDIP footprint and that the serial interface timing meets the microcontroller's requirements.

Analog To Digital Converters (ADC) Part Context

This component belongs to the MAX1240/MAX1241 family of low-power, 12-bit serial ADCs manufactured by Analog Devices / Maxim Integrated. The series offers small footprint options in both SO and PDIP packages. The MAX1241 variant specifically targets applications requiring flexible reference voltage configurations while maintaining low power consumption.

Analog To Digital Converters (ADC) Replacement Considerations

The MAX1240ACPA+ serves as a functional alternative if an internal 2.5V reference is acceptable instead of an external one. Other members of the MAX124x family may be considered based on package type or temperature range requirements.
