ADC0834CIWM

Analog To Digital Converters (ADC) Overview

The ADC0834CIWM is an 8-bit successive approximation analog-to-digital converter (ADC) manufactured by National Semiconductor. It features a serial input/output interface compatible with standard microprocessor protocols and includes an internal multiplexer for multiple channel selection. The device operates on a single 4.5V to 6.3V power supply and supports sampling rates up to 31.25 kSPS. Packaged in a 14-pin SOIC format, it integrates a track-and-hold circuit and requires an external reference voltage. Key electrical specifications include a maximum conversion time of 32 µs and a linear error of 0.3906%.

• Microprocessor-based measurement systems

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADC083x family of 8-bit serial A/D converters from National Semiconductor. The 'CI' suffix indicates commercial temperature range (-40°C to +85°C), while 'WM' denotes the 14-SOIC surface-mount package. This series provides a cost-effective solution for applications needing moderate speed and resolution with minimal digital interface wiring.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible alternatives within the same family include the ADC0834CCN (PDIP package) or ADC0834CN. For surface-mount replacements, verify if the ADC0834CIM (SOIC-16) or similar variants meet the specific package width requirements, as pinouts may differ slightly between SOIC-14 and SOIC-16 packages.
