TC7109CPL Microchip Know-how Inc

The TC7109A is a 12-bit plus sign, CMOS low power Analog-to-Digital Converter (ADC). Solely eight passive components and a crystal are required to sort a whole twin slope integrating ADC. The improved VOH provide current and totally different TC7109A choices make it a lovely per-channel numerous to analog multiplexing for lots of data acquisition features. These choices embrace typical enter bias current of 1pA, drift of decrease than 1μV/°C, enter noise often 15μVP-P, and auto-zero. True differential enter and reference allow measurement of bridge form transducers, just like load cells, strain gauges and temperature transducers. The TC7109A offers a versatile digital interface. Inside the Direct mode, Chip Select and HIGH/LOW byte enable administration parallel bus interface. Inside the Handshake mode, the TC7109A will operate with enterprise customary UARTs in controlling serial info transmission – easiest for distant info logging. Administration and monitoring of conversion timing is provided by the RUN/HOLD enter and Standing output.
