Analog To Digital Converters (ADC) Procurement Notes

Verify the component status as obsolete or lifetime buy through official Texas Instruments channels before procurement planning. Confirm package availability in SOIC-24 format. Ensure supply chain partners provide valid traceability documentation. Check for alternative lifecycle management options if long-term production support is required for the design.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 10-bit resolution with signed output format is necessary for bipolar signal processing. The internal multiplexer reduces board space by accommodating up to 8 channels. Ensure the system clock frequency remains within the 5 kHz to 3 MHz range for proper serial data exchange. Verify that the analog input voltage does not exceed the supply rails by more than 50 mV to maintain accuracy.

Analog To Digital Converters (ADC) Part Context

The ADC10738CIWM belongs to the ADC1073x family, which includes the ADC10731, ADC10732, and ADC10734 variants. These devices share identical core architecture but differ in channel count and pin configuration. The ADC10738 specifically provides eight analog inputs, whereas other family members offer fewer channels. This series represents a specialized solution for low-power, multi-channel data conversion tasks.

Analog To Digital Converters (ADC) Replacement Considerations

The ADC10731, ADC10732, and ADC10734 are obsolete and included for reference only. No direct functional replacements are listed in the provided datasheet. Designers should evaluate newer Texas Instruments ADC families with similar serial interfaces and resolution specifications for modern implementations.
