ANALOG OUTPUT CHARACTERISTICS
Notes: 10. Guaranteed by design and/or characterization.
11. Load on the precision OUT± outputs is normally from a CS3301A/02A amplifier, which has 2 GΩ/1 TΩ
typical input impedance and 18 pF typical input capacitance.
12. Single-ended output impedance at 1/64 is different for BUF+ and BUF- due to the output attenuator
architecture.
