Manufacturer Part Number

MAX1243BCSA

Description

10-bit SAR analog to digital converter in an 8-pin SOIC package. Converts analog signals to digital using successive approximation register technique. Offers single input channel, SPI compatible data interface, and easy integration for embedded systems.

Specifications

Converter resolution is 10 bits. Sampling rate is up to 73 kSPS. Supports one single-ended input. Operates with analog and digital supply voltages from 2.7V to 5.25V. Uses external reference voltage. Input and output interface via SPI protocol. Encased in standard 8-SOIC package, 3.90mm wide.

Device Structure

Single channel, single-ended input, SAR architecture. Includes sample-and-hold circuit integrated with ADC core. SPI digital output. Surface-mount package for direct PCB attachment.

Performance Characteristics

Fast conversion time with up to 73,000 samples per second. High accuracy and stable operation through external reference option. Low supply voltage operation enables battery-powered applications. Designed for optimal performance across standard temperature range from 0°C to 70°C.

Application Environments

Useful in embedded system signal acquisition. Suitable for data loggers, sensor interfacing, portable instruments, industrial automation, medical devices, and general analog measurement. Best used where moderate resolution and sampling rates are acceptable.

Selection Guidelines

Choose if application requires up to 10-bit conversion resolution and speeds up to 73kSPS. Make sure to match supply voltage range (2.7V-5.25V) and external reference usage. Verify compatibility with SPI data transfer requirements. Confirm size and mounting style fit with your board design.

Usage Considerations

Refer to the product datasheet for details on external reference requirements. Ensure clean supply voltages and careful PCB layout for accurate conversion. Device is RoHS non-compliant; consider environmental regulations. Expects surface-mount assembly and standard handling for MSL 1 rating (unlimited shelf life). No advanced features; design for basic ADC operation.
