ADC0838BCVX

Analog To Digital Converters (ADC) Overview

The ADC0838BCVX is an 8-bit successive approximation analog-to-digital converter (ADC) from Texas Instruments, part of the ADC0831-N series. It features a software-configurable multiplexer supporting up to 8 input channels with single-ended, differential, or pseudo-differential modes. The device operates on a single 5 VDC supply (4.5 V to 6.3 V), consumes 15 mW, and delivers a conversion time of 32 μs at a clock frequency of 250 kHz. It utilizes a TI MICROWIRE-compatible serial interface for direct processor connection.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'X' against the official datasheet, as standard listings typically reference 'ADC0838BCV'. Confirm package type and temperature range specifications directly with the manufacturer or authorized distributors to ensure compliance with design requirements.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring flexible analog input configurations within a compact 20-pin PLCC package. Ensure the system clock frequency remains between 10 kHz and 400 kHz. 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

This device belongs to the ADC0831-N family, which includes variants with different channel counts (1, 2, 4, and 8). The ADC0838 variant specifically provides the highest channel count (8) in a 20-pin package, distinguishing it from the smaller footprint options like the ADC0831 or ADC0832.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements include other members of the ADC0831-N family such as the ADC0838CCV or ADC0838CIWM, provided the temperature range and error specifications meet the application needs.
