General Description
The TC3401 is a low cost, low power analog-to-digital converter based on Microchip’s Sigma-Delta technology. It will perform 16-bit conversions (15-bit plus sign) at up to eight per second. The TC3401 is optimized for use as a microcontroller peripheral in low cost, battery operated systems. A voltage reference is included, or an external reference can be used. A VDD monitor with a reset generator provides Power-on Reset and Brownout protection while an extra threshold detector is suitable for use as an earl……
