SK035M0470B5S-1019 on stock Differential Output Feature The multiple-feedback filter section of Figure l inherently includes two outputs of opposite signal polarity: a DC- inve rting outputfrom the OA (Pinl) and a DC noninve rting output from the INV block (Pin 7). These two outputs maintain equal gain and 1800 phase shift over a wide frequency range. This feature permits choosing the signal polarity in single-ended applications, and also performs single-ended-to-differential conversion. The latter prop- erty is useful in an antialias filter to drive standard mono- lithic A/D converters having differential inputs, as illus- trated on page l. The LTC1250's zero-drift nulling loop samples the input at 05kHz, allowing it to process signals below 2kHz with no aliasing. Signals above this frequency may show aliasing behavior, although wideband internal circuitry generally keeps errors to a minimum. The output of the LTC1 250 will have small spikes at the clock frequency and its harmonics; these will va ry in amplitude with different feedback configu- rations. Low frequency or band-limited systems should not be affected, but systems with higher bandwidth (oversampling A/Ds, for example) may need to filter out these clock artifacts. Output spikes can be minimized with a large feedback capacito r, but this will adve rsely affect noise performance (see Input Capacitance and Compensation on |
