CHARACTERISTICS AND SPECIFICATIONS

VA- = -2 V ±10%; External VREF+ = 1.2 V; XIN = 4.000 MHz; AGND, DGND = 0.0V.) (See Notes 1 and 2)

Notes: 1. Specifications guaranteed by design, characterization, and/or test.

2. Analog signals are relative to AGND and digital signals to DGND unless otherwise noted.

3. Effective Input Impedance (EII) varies with clock frequency (XIN) and Input Capacitance (IC)

EII = 1/(IC*XIN/4)
