2.4.2 THS5651 – Parallel Output CommsDAC
This 10-bit data converter has a parallel interface and is able to update its output
with 100 MSPS. The two outputs on the 28-pin package can each drive a current
between 2 mA and 20 mA with an output resistance >100 k
Ω
(ideal current
source: output impedance
→ ∞
). The data bus and the address decoder provide
the interface to the DSP.
