Product Details

The AD364 is a complete 16-channel data acquisition system which conditions and subsequently converts an analog voltage into digital form. Each system consists of two devices, an analog input stage (AIS) and an analog-to-digital converter (ADC). The AIS includes a two 8-channel multiplexers, a channel address register, a unity gain instrumentation amplifier, and a sample-hold amplifier. The multiplexers may be connected to the instrumentation amplifier in either an 8-channel differential or 16-channel single ended configuration. A unique feature of this product is an internal user controlled switch which connects the multiplexers in either single-ended or differential mode. This allows a single device to perform in either mode with hard-wire programming and permits interfacing a mixture of single-ended and differential signals by dynamically switching the input mode control.

The AD364 is a ADC complete with a complete 12-bit successive approximation converter including an internal clock and a precision reference. Active laser trimming results in maximum linearity errors of ± 0.012% with conversion times of 32 µs. The hybrid AD364-ADC is a monolithic converter with 3-state output buffer circuitry for direct interface to an 8-, 12-, or 16-bit processor bus and three user selected input ranges (±5, ±10, and 0 to +10 volts).
