D83P Series Programmable Amplifier -12 dB to +60 dB Description The D83P Series programmable amplifiers are digitally controlled gain modules that were designed for conditioning DC-coupled wide-band signals (AC coupled-optional). They are programmable from -12 dB to +60 dB in 6 dB steps with an 4 -bit p a r a l l e l w o r d . Other standard performance features include differential input, single ended output, 5V interface logic, and low noise and distortion, making this plug-in ready-to-use amplifier ideal for many signal conditioning applications. Available options include AC coupled input and/or differential output. Features/Benefits: • Full power bandwidth to 100 kHz for wide dynamic range applications • Compact 1.8" x 0.8" x 0.3" (32 pin DIP) size minimizes board space requirements • Parallel 4-bit word for easy gain control. • Data out line allows data verification and cascading of multiple amplifiers over the same serial interface. • Plug-in ready-to-use, reducing engineering design and manufacturing time.
