Analog To Digital Converters (ADC) datasheet and documents for ADC08038CIWMX
Analog To Digital Converters (ADC) Overview
The ADC08038CIWMX is an obsolete 8-bit successive approximation analog-to-digital converter (ADC) from Texas Instruments, housed in a 20-pin SOIC package. It features a configurable input multiplexer supporting up to eight channels with single-ended, differential, or pseudo-differential modes. The device operates on a single 5V supply (4.5V to 6.3V) and includes an internal 2.6V band-gap reference. Key electrical specifications include a maximum conversion time of 8 μs at a 1 MHz clock frequency, a total unadjusted error of ±1 LSB for the CIWM suffix, and a maximum power dissipation of 20 mW.
Analog To Digital Converters (ADC) Feature Summary
- Configurable 8-channel input multiplexer supporting single-ended, differential, and pseudo-differential input modes
- Serial I/O interface compatible with NSC MICROWIRE standard, requiring minimal processor pins
- Integrated 2.6V band-gap voltage reference for absolute accuracy applications
- On-chip track/hold function allows analog voltage variation during the conversion cycle
Analog To Digital Converters (ADC) Applications
- Digitizing automotive sensors
- Process control monitoring systems
- Remote sensing in noisy environments
- Embedded diagnostics and instrumentation
Analog To Digital Converters (ADC) Part Context
The ADC08038CIWMX belongs to the ADC0803x family, which also includes the ADC08031, ADC08032, and ADC08034. These devices share identical SAR architecture and serial communication protocols but differ in channel count and pin configurations. The 'CIWM' suffix denotes the industrial temperature range (-40°C to +85°C) and the 20-pin Small Outline Integrated Circuit (SOIC) package variant.
Analog To Digital Converters (ADC) Replacement Considerations
Texas Instruments has designated the ADC08038CIWMX as obsolete. No direct replacement part numbers are listed in the provided documentation. Designers must evaluate alternative ADCs based on required resolution, sampling speed, and interface compatibility.
