General Description
The TC3405 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 TC3405 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 early warning power fail detector, or as a Wake-up Timer. The TC3405’s 2-wire microPort digital interface is use……
