ADC10732CIWM

Analog To Digital Converters (ADC) Overview

The ADC10732CIWM is a CMOS 10-bit plus sign successive approximation A/D converter featuring a 2-channel analog input multiplexer, sample/hold function, and integrated 2.5V band-gap reference. It operates on a single 5V supply with a maximum power consumption of 37mW and 18μW in power-down mode. The device supports serial I/O compatible with MICROWIRE standards, allowing interface with standard controllers. Key specifications include a maximum conversion time of 5μs, a sampling rate up to 74kHz, and no missing codes over the operating temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

The ADC10732 is classified as obsolete or on lifetime buy by Texas Instruments. Verification of current availability through authorized distributors is required before procurement planning. Designers should consider lifecycle status implications for long-term production support.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a low-pin-count, single-supply 10-bit ADC with an internal reference is needed. It is suitable for applications requiring up to two analog inputs with multiplexing capabilities. Ensure the system can accommodate the MICROWIRE serial interface timing requirements and that the 5V supply voltage aligns with the design constraints.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC1073x family, which includes the ADC10731 (1 channel), ADC10734 (4 channels), and ADC10738 (8 channels). All variants share similar architectural features, including the SAR conversion method and serial interface, differing primarily in the number of available analog input channels.

Analog To Digital Converters (ADC) Replacement Considerations

As the ADC10732 is obsolete, direct replacements may not be available from the original manufacturer. Engineers should evaluate newer Texas Instruments ADC families or third-party equivalents that offer compatible pinouts, interface protocols, and performance specifications.
