ADC0834CCWM

Analog To Digital Converters (ADC) Overview

The ADC0834CCWM is an 8-bit successive approximation analog-to-digital converter manufactured by Texas Instruments. It features a software-configurable multiplexer supporting four single-ended or two differential input channels. The device 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. It utilizes a TI Microwire-compatible serial interface for data exchange, allowing direct connection to microprocessors. The total unadjusted error is specified at ±1 LSB, and the conversion time is determined by the clock frequency.

Analog To Digital Converters (ADC) Applications

• Industrial Control Systems Signal Acquisition
• Automation Test Equipment
• Sensor Signal Processing

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix CCWM indicates the commercial temperature range (0°C to +70°C) and SOIC package variant. Confirm RoHS compliance status as older revisions may differ. Ensure the source document matches SNAS531B specifications for electrical limits. Check availability as this component series has legacy status in some distributor catalogs.

Analog To Digital Converters (ADC) Selection Notes

Select the ADC0834CCWM when four analog inputs are required within a compact surface-mount footprint. The device is suitable for applications needing ratiometric operation or absolute accuracy via external reference. Ensure the system clock frequency remains between 10 kHz and 400 kHz to meet timing requirements. Verify that the input signal impedance does not exceed 1 kΩ without buffering.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADC0831-N family, which includes variants with different channel counts and packages. The ADC0834 specifically provides four input channels, distinguishing it from the single-channel ADC0831 and two-channel ADC0832. The CCWM suffix denotes the wide-body SOIC package and commercial temperature grade.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements include other members of the ADC083x series such as the ADC0832 or ADC0838, provided the channel count meets design needs. Modern low-power alternatives like the TLV0834 offer similar functionality but operate at lower voltages (2.7V to 3.6V) and require level shifting if interfacing with 5V logic systems.
