DC2398A Demo Circuit for LTC6373

Analog Devices DC2398A Demo Circuit for LTC6373 features the LTC6373 programmable gain instrumentation amplifier. The circuit’s gain can be controlled in several ways, such as by simply setting onboard jumpers or by connecting an Arduino or Linduino (DC2026A) microcontroller board. The LTC6373 has fully differential outputs with independent common mode level shifting. The output common mode level can be set by the ICs internal default or overdriven by the user. The DC2398A can be powered by external bench supplies (typically ±15V), but optionally also demonstrates the use of the LTC3265 dual low noise charge pump to generate ±15V rails from a single 9V to 12V input supply.
