This current passed through resistor into internal reference voltage component, preamplifier output being signal centering internal reference voltage. systems (positive phase negative phase) created during conversion, generating output driver buffer. Regulator This typical series regulator that generates reference voltage internally. saturation types transistor must connected. BA6398FP Operational amplifier standard 4558 type. FApplication example FOperation notes BA6398FP internal thermal shutdown circuit. Output current muted when chip temperature exceeds 175_C (typically). mute (pin voltage opened lowered below 0.5V, output current will muted. should pulled above 2.0V during normal use. bias (pin muted when lowered below 1.4V (typically). Make sure stays above 1.6V during normal use. driver circuit shuts down when supply voltage drops below 4.5V (typically), starts again when voltage rises above 4.7V (typically). Muting occurs during thermal shutdown, mute-on operations drop bias voltage supply voltage. each case, only drivers muted. During muting, output pins remain internal bias voltage, roughly (VCC-VF) BA6398FP internal input resistor positive temperature coefficient roughly 2000ppm degree, when changing gain using attached resistor, gain will also change rate roughly 2000ppm degree. There virtually gain variation temperature when using internal input resistor. sure connect 0.1µF bypass capacitor power supply, base radiating connected package's internal GND, should also connected external ground. capacitor between regulator output (pin also serves prevent oscillation select with good temperature characteristics.
