CHARACTERISTICS AND SPECIFICATIONS

•

Min / Max characteristics and specifications are guaranteed over all Operating Conditions

•

•

DGND = 0 V. All Voltages with respect to 0V.

ANALOG CHARACTERISTICS

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)
