Description
Ground for all Analog Circuitry.
Current Output. This is a high impedance current source output. A load resistor of nominally 200 Ω should be
connected between IOUT and AGND. A 20 pF capacitor to AGND is also recommended to act as a low-pass filter
and to reduce clock feedthrough. In conjunction with IOUTB, a differential signal is available.
Current Output. IOUTB is the compliment of IOUT. This pin should preferably be tied through an external load
resistor of 200 Ω to AGND, but can be tied directly to AGND. A 20 pF capacitor to AGND is also recommended as a
low-pass filter to reduce clock feedthrough. In conjunction with IOUT, a differential signal is available.
