General Description
The AS1713 is a low cost cmos difference amplifier providing extended common mode voltage range for a single rail 5V supply. Resistor trimming during final test ensures a typical common mode rejection of 60dB. Low input bias currents, 10MHz gain bandwidth, low total harmonic distortion (THD) and a rail-to-rail output drive capability of typically 200mA (@ 5V supply) provide support for a number of signal processing applications such as audio line receivers, ground loop breakers and current sensing. Linearity is suitable for 12bit ADC measurement.
