ADC0838CIWMX

Analog To Digital Converters (ADC) Overview

The ADC0838CIWMX is an 8-bit successive approximation analog-to-digital converter featuring an 8-channel multiplexer. It operates on a single 5 VDC supply with a voltage range of 4.5 V to 6.3 V and consumes 15 mW of power. The device supports serial I/O compatible with TI MICROWIRE standards, allowing direct interface with microprocessors. It offers configurable input modes including single-ended, differential, and pseudo-differential configurations. The total unadjusted error is specified at ±1 LSB for the CIWM variant, with a conversion time of 32 μs.

Analog To Digital Converters (ADC) Procurement Notes

Verify that the ordering suffix 'X' corresponds to tape-and-reel packaging as indicated by distributor listings. Confirm the specific temperature grade associated with the 'CIWM' designation against the manufacturer's current production data sheets to ensure compliance with required operating conditions.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an 8-channel multiplexed input is required within a single package. The CIWM variant provides a total unadjusted error of ±1 LSB, suitable for general-purpose applications where higher precision variants like the BCV are not necessary. Ensure the system clock frequency remains within the 10 kHz to 400 kHz range for proper operation.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC0831-N series, which includes variants with different channel counts and pin configurations. The ADC0838-N specifically provides 8 channels in a 20-pin package. Other members of the family include the ADC0831 (1 channel), ADC0832 (2 channels), and ADC0834 (4 channels).

Analog To Digital Converters (ADC) Replacement Considerations

The TLV0838 is a low-voltage successor offering similar functionality but operating at 2.7 V to 3.6 V. Direct replacement requires verifying voltage level compatibility and ensuring the lower supply voltage meets system requirements.
