MAX1241BCSA

Analog To Digital Converters (ADC) Overview

The MAX1241BCSA is a low-power, 12-bit analog-to-digital converter (ADC) manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single +2.7V to +5.25V supply and features a successive-approximation register architecture with a throughput rate of 73 ksps. The device utilizes an external reference voltage at the REF pin and includes an internal track/hold circuit with a 1.5µs acquisition time. Power consumption is 3mW at maximum sampling speed, reducing to 5µW in power-down mode. It communicates via a high-speed, 3-wire serial interface compatible with SPI, QSPI, and MICROWIRE protocols.

Analog To Digital Converters (ADC) Feature Summary

• Compact 8-pin SO package footprint

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 component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and lead-free packaging requirements prior to procurement. Ensure ordering suffixes match specific temperature ranges and accuracy grades. Request official datasheets and test reports to validate electrical characteristics against application specifications.

Analog To Digital Converters (ADC) Selection Notes

Select the MAX1241BCSA when an external reference voltage is required rather than an internal one. This variant offers ±1 LSB integral nonlinearity within the commercial temperature range. Consider the MAX1240 series if an integrated 2.5V reference simplifies the design. Evaluate source impedance constraints to ensure the 1.5µs acquisition time meets signal bandwidth requirements.

Analog To Digital Converters (ADC) Part Context

This component belongs to the MAX1240/MAX1241 family of low-power, 12-bit serial ADCs. The MAX1241 variant specifically requires an external reference, distinguishing it from the internally referenced MAX1240. Both share identical SAR architectures and serial interfaces but differ in reference configuration and supply voltage flexibility.

Analog To Digital Converters (ADC) Replacement Considerations

Direct replacements include other members of the MAX1240/MAX1241 family such as the MAX1241ACSA or MAX1241CCSA, which offer different accuracy grades and temperature ranges. Verify pin compatibility and reference requirements before substitution.
