Description

This circuit performs the function of producing a ±10V voltage output where both a high level of accuracy and a fast update rate are desired. This is achieved by combining the fast settling time and precision of a 16-bit unbuffered R-2R DAC (DAC8832) and the low input offset voltage and fast slew rate of two output amplifier stages (OPA2192). The circuit provides an analog output voltage useful for precisely tuning feedback circuits as well as driving off-board components.

Features
  • ±10 V output range
  • Less than 0.1% TUE FSR
  • Output settles in less than 5 µs to ±2 LSBs
  • Less than 0.5 LSBs of flicker noise
