Аналогово Цифровые Преобразователи (АЦП) TC7109CPL

АЦП , 12 бит, 10 выборок/с, Дифференциальный, Параллельный, Последовательный, Однополярный, 4.5 В

The TC7109CPL is a 12-bit µA-compatible Analog-to-digital Converter (ADC) provides a versatile digital interface. In the direct mode, chip select and HIGH/LOW byte enable control parallel bus interface. In the Handshake mode, the TC7109A will operate with industry standard UARTs in controlling serial data transmission - ideal for remote data logging. Control and monitoring of conversion timing is provided by the RUN/HOLD input and Status output. The plus sign, CMOS low power ADC has only eight passive components and a crystal are required to form a complete dual slope integrating ADC. The improved VOH source current and other TC7109A features make it an attractive per-channel alternative to analog multiplexing for many data acquisition applications. True differential input and reference allow measurement of bridge type transducers such as load cells, strain gauges and temperature transducers.

• Zero integrator cycle for fast recovery from input overloads
• Eliminates cross-talk in multiplexed systems
• Sign magnitude coding format
• True differential signal input and differential reference input
• No zero adjustment needed
• TTL Compatible, byte organized tri-state outputs
