PARAMETER MEASUREMENT INFORMATION
single-supply versus split-supply test circuits
Because the TLC2810Z is optimized for single-supply operation, circuit configurations used for the various tests
often present some inconvenience since the input signal, in many cases, must be offset from ground. This
inconvenience can be avoided by testing the device with split supplies and the output load tied to the negative
rail. A comparison of single-supply and split-supply test circuits is shown below. The use of either circuit gives
the same result.
