10.1 Bias Supply Voltage

The recommended bias supply voltage range for LM5111 is from 3.5 V to 14 V. The upper end of this range is driven by the 15-V absolute maximum voltage rating of the VCC. TI recommends keeping proper margin to allow for transient voltage spikes. A local bypass capacitor must be placed between the VCC and VEE pins, and this capacitor must be placed as close to the device as possible. TI recommends a low ESR, ceramic surface mount capacitor. TI recommends using 2 capacitors across VCC and VEE: a 100-nF ceramic surface-mount capacitor for high frequency filtering placed very close to VCC and VEE pin, and another surface-mount capacitor, 220 nF to 10 µF, for IC bias requirements.
