Description:

Sum-It is a tiple channel, unity-gain buffer. The input sections use NOS JFETs that have been biased for optimum performance. The output section is constructed from two op-amps in parallel providing lower noise and higher current drive.

The output signal is in phase with the input signal.

Suggested Uses:

Sum-It is well suited for:

• driving long cable lengths to avoid tonal loss

• combining multiple signals to a single output

• converting high-Z input to low-Z output

• buffering signals in/out of Swytch-It
