Overview
The TLV0838CDW is an 8-bit successive-approximation analog-to-digital converter (ADC) produced by Texas Instruments. This device features an input-configurable multichannel multiplexer and serial input/output, making it versatile for various applications. It is designed to operate within a voltage range of 2.7-V to 3.6-V and is available in a SOIC (DW) package with 20 pins. The TLV0838CDW is functionally equivalent to the ADC0834 and ADC0838 at a 3-V supply, but without the internal Zener regulator network.
