Overview
The TLV0838CDWR 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 suitable for a variety of applications requiring precise analog-to-digital conversion. The TLV0838 is designed to operate with a supply voltage range of 2.7 to 3.6 volts and is available in a 20-pin SOIC (DW) package. It is functionally equivalent to the ADC0834 and ADC0838 at 3-volt supply without the internal Zener regulator network.
