Notes: The device has been designed for a negative supply system. It can be also used for positive supply systems
if the input signals are referred to VCC, VDD.
DC Characteristics
These characteristics are guaranteed for all settings of cutoff frequency and gain(unless otherwise stated).
The value of the external DAC resistor is R_DAC = 4.5 kΩ.
