DESCRIPTION

· The TC500/A/510/514 family are precision analog front ends with dual slope A/D converters, offering up to 17-bit resolution.

· Each device includes an integrator, zero crossing comparator, and processor interface logic.

· The TC500 operates with dual power supplies, while the TC500A offers improved linearity.

· The TC510 supports single-supply operation with an onboard negative power supply converter.

· The TC514 adds a 4-input differential analog multiplexer for enhanced functionality.

FEATURES
