Unipolar-to-Bipolar Level Translator 0V to 5V Unipolar to ±10V Bipolar Converter

This design is intended to translate a small unipolar signal to a wide bipolar signal. A common application is to translate a 0 to 5V DAC output to a ±10V bipolar signal. All resistors are 1% but it is advisable to select 0.1% 20 ppm/°C resistors for good gain, offset accuracy, and...
