PARAMETER MEASUREMENT INFORMATION

single-supply versus split-supply test circuits

Because the TLC272 and TLC277 are 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 versus split-supply test circuits is shown below. The use of either

circuit gives the same result.
