MAX1240AESA+

Analog To Digital Converters (ADC) Overview

The MAX1240AESA+ is a low-power, 12-bit successive-approximation analog-to-digital converter (ADC) housed in an 8-pin SO package. It operates on a single +2.7V to +3.6V supply and features a 7.5µs conversion time with a maximum throughput rate of 73ksps. The device includes an internal 2.5V reference and a fast track/hold circuit with a 1.5µs acquisition time. Power consumption is 37mW at full speed, reducible via a shutdown mode. It utilizes a high-speed, 3-wire serial interface compatible with SPI, QSPI, and MICROWIRE protocols.

Integrated 12-bit SAR architecture with internal 2.5V voltage reference
Low power operation with dedicated shutdown mode for extended battery life
Fast track/hold circuitry supporting high-speed data acquisition
Flexible 3-wire serial interface compatible with standard microcontroller ports

Analog To Digital Converters (ADC) Applications

Battery-powered portable systems
Portable data logging equipment
Isolated data acquisition modules
Industrial process control instrumentation

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'E' indicates the extended temperature range (-40°C to +85°C). Confirm the '/V' designation if automotive qualification is required. Ensure the '+' suffix confirms lead-free and RoHS compliance status. Cross-reference the manufacturer's current ordering information to validate availability and exact pinout specifications before finalizing procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel, 12-bit resolution is sufficient for the application. Choose the MAX1240 over the MAX1241 if an integrated internal reference is preferred to reduce external component count. Consider the 73ksps sampling rate against signal bandwidth requirements. Evaluate the 8-pin package size constraints relative to available PCB real estate.

Analog To Digital Converters (ADC) Part Context

This part belongs to the MAX1240/MAX1241 family of low-power serial ADCs. The MAX1240 variant distinguishes itself by incorporating an internal 2.5V reference, whereas the MAX1241 requires an external reference source. Both share identical SAR architectures and serial interfaces but differ in supply voltage ranges and reference configurations.
