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 parallel word. 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 Parrallel 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. Applications Data acquisition Test equipment Remote instrumentation systems Ground loop elimination in remote measurements Improvements in system dynamic range and resolution Telemetry Process control Digitally controlled auto ranging systems Medical, Scientific & engineering research   Gain Amplifier Digital Programming & Control The D83P programs via a four terminal parallel data interface over a gain range from 0.25 (~ -12dB) to 1024 (~+60dB). Two stages of programmable gain/attenuation are used to optimize the D-C offset and gain bandwidth performance.   Programming Table Gain ( V/V ) Gain (~dB) D0 D1 D2 D3 1/4 -12.04 0 0 0 0 1/2 -6.02 1 0 0 0 1 0.00 0 1 0 0 2 +6.02 1 1 0 0 4 +12.04 0 0 1 0 8 +18.06 1 0 1 0 16 +24.08 0 1 1 0 32 +30.10 1 1 1 0 64 +36.12 0 0 0 1 128 +42.14 1 0 0 1 256 +48.16 0 1 0 1 512 +54.19 1 1 0 1 1024 +60.21 0 0 1 1   Specifications (@ 25°C and Vs ±15 Vdc) Analog Input Characteristics Configuration: DC coupled, differential Input AC Coupled (Optional): Fixed @ 10Hz Impedance: 1 MΩ || 22pF Bias Current: 20 pA max.
