EVAL-AD7329CBZ

The AD7329 can input true bipolar analog signals and is available in four software-selectable ranges: ±10V, ±5V, ±2.5V, and 0 to 10V. Each analog input channel is independently programmable and can be set to one of four input ranges by setting the corresponding bit in the range register.

The analog input channels can be configured in one of three modes: single-ended, fully differential, or pseudo-differential. The analog inputs are configured via special control register bits.

The ADC has an internal 2.5 V reference voltage or an external reference. If in REF_IN/OUT A 3V external reference voltage is applied to the pin, and the ADC can handle ± 12V true bipolar analog input range. For this ±12V input range, a V of ±12V is required_DD and V_SS Power supply.

The AD7329 has multiplexer output pins and ADC input pins. These pins allow the user to insert buffers, differential amplifiers, or antialiasing filters between the multiplexer and ADC if necessary, meaning that only one driver is required for all eight analog inputs in the AD7329.

The AD7329 supports several power-down modes that reduce power consumption levels by reducing throughput.

Product Focus
