• Manufacturer Part Number: AD7367-5ARUZ
• Description: 1 MSPS, 8-Channel, Software-Selectable, True Bipolar Input, 12-Bit Plus Sign ADC
• Manufacturer: AD [Analog Devices]

This voltage is set up externally, and its range varies with
reference voltage. As the reference voltage increases, the
common-mode range decreases. When driving the differential
inputs with an amplifier, the actual common-mode range is
determined by the amplifier’s output swing. If the differential
inputs are not driven from an amplifier, the common-mode
range is determined by the supply voltage on the V
and the V
When a conversion takes place, the common mode is rejected,
resulting in a noise-free signal of amplitude −2 × (4 × V
(4 × V
