2. CHARACTERISTICS AND SPECIFICATIONS
• Min / Max characteristics and specifications are guaranteed over all Operating Conditions
• Typical characteristics and specifications are measured at nominal supply voltages and TA = 25 °C.
• DGND = 0 V. All Voltages with respect to 0V.

Notes: 1. All “Gain = 20” specifications apply only to the Current Channels. Voltage Channels are set to Gain=1.
2. Effective Input Impedance (EII) varies with clock frequency (XIN) and Input Capacitance (IC)
EII = 1/(IC*XIN/4)
