ADC1034CIWMX

Analog To Digital Converters (ADC) Overview

The ADC1034CIWMX is a 10-bit analog-to-digital converter manufactured by National Semiconductor, now part of Texas Instruments. It features a serial I/O interface and integrates an analog multiplexer with a track-and-hold function. The device operates within a supply voltage range of 2.7 V to 5.5 V and supports sampling rates up to 200 kSPS. Key electrical parameters include a differential nonlinearity (DNL) of ±1 LSB and integral nonlinearity (INL) of ±2 LSB. It utilizes a SAR architecture and communicates via a standard 3-wire serial port compatible with SPI and QSPI.
