Module A-183-4 is a fourfold level shifter. A level shifter is required if the level of a digital control signal has to be increased or decreased. It can be used also to improve the slew rate (or edge steepness) of a signal
A typical application is the conversion of a gate, trigger or clock signal with +5V voltage level (or any level beyond +3V) to +12 voltage level. Another application is to sharpen the rising and falling edge of a signal. In some cases (e.g. triggering an envelope generator) a fast rising edge may be required. If the slew rate (and/or level) of the available gate signal is not sufficient module A-183-4 is the right choice.
The output voltage level can be set by means of a jumper to +12V or +5V. The factory setting is +12V. But it can be changed to convert also a higher to a lower level (e.g. +12V to +5V). But this application is required rarely. The output level setting by means of the jumper is global, i.e. it is valid for all four units and cannot be set individually for each unit.
voltages above +3 V are treated as "high"
Typical applications
- Converting the levels of digital control signals (e.g. gate, trigger, clock) to another voltage level (+12V or +5V)
- >buffering and duplicating digital control signals (e.g. gate, trigger, clock)
- improving the edges of "flabby" digital control signals
- Important note: the module cannot be used for analog signals ! With an analog input signal the module does work only as a comparator. But in can be used to derive a digital signal with fast slopes from a slowly varying analog signal (e.g. triangle of an LFO). With the aid of an offset generator (e.g. A-183-2) the crossover point can be adjusted.
